Eragon Bromsson Respect Thread [Completed 4/15/15]

Respect for Eragon Shadeslayer, son of the late Dragon Rider Brom, and the first in a new era of Dragon Riders.

Eragon is one of my favorite characters in any book I've read, and I'm surprised he's not used very often in battles on here. So I've taken the liberty to make this respect thread for him in order to sort of "get his name out there" and help him become more known, as well as help others gauge him and where he stands against other characters.

Here's an update on his appearance after the Blood-oath Celebration:

It was as if the numerous physical changes that, over time, alter the appearance of a human Rider----and which Eragon had already begun to experience since bonding with Saphira----had been completed while he was unconscious. His face was now as smooth and angled as an elf's, with ears tapered like theirs and eyes slanted like theirs, and his skin was as pale as alabaster and seemed to emit a faint glow, as if with the sheen of magic. I look like a princeling. Eragon had never before applied the term to a man, least of all himself, but the only word that described him now was beautiful. Yet he was not entirely an elf. His jaw was stronger, his brow thicker, his face broader. He was fairer than any human and more rugged than any elf.

[...]

Not only was the savage blight he had elected to keep gone, but every other scar and blemish had vanished from his body, leaving him as unmarked as a newborn babe. Eragon traced a line upon his wrist where he had cut himself while sharpening Garrow's scythe. No evidence of the wound remained. The blotchy scars on the insides of his thighs, remnants from his first flight with Saphira, had also disappeared. For a moment, he missed them as a record of his life, but his regret was short-lived as he realized that the damage from every injury he had every suffered, no matter how small, had been repaired.

Tracking and Hunting Skills

This section will be devoted to Eragon's skills in tracking and hunting down game. When he was younger, Eragon would routinely venture into the Spine, a region of dangerous mountains near Carvahall that almost nobody knew how to survive and navigate it correctly, and sometimes spent days tracking his prey. All of these feats are before he began his training as a Dragon Rider, so after his education from Oromis, he would be extremely more knowledgeable and capable.

Eragon is a skilled tracker, hunting a deer through the Spine for three days. The Spine is a dangerous stretch of mountains that very nearly everyone tries to avoid:

The deer had led him deep into the Spine, a range of untamed mountains that extended up and down the land of Alagaesia. Strange tales and men often came from those mountains, usually boding ill. Despite that, Eragon did not fear the Spine----he was the only hunter near Carvahall who dared track game deep into its craggy recesses.

[...]

Eragon slowly crept closer, keeping the bow ready. All his work of the past three days had led to this moment.

Roran muses that Eragon's hunting skills are better than his:

Intelligence

Eragon learns as much as he can while in Ellesmera from scrolls that Oromis gave him. From these scrolls, Eragon learned about subjects such as geography, biology, anatomy, philosophy, mathematics, and read personal memoirs, biographies, and histories:

When not with Oromis, Eragon supplemented his education by reading the many scrolls the elf gave him, a habit he soon became addicted to. Eragon's rearing----limited as it was by Garrow's scant tutelage----had exposed him only to the knowledge needed to run a farm. The information he discovered on the miles of paper flooded into him like rain on parched desert, sating a previously unknown thirst. He devoured texts on geography, biology, anatomy, philosophy, and mathematics, as well as memoirs, biographers, and histories. More important than mere facts was his introduction to alternative ways of thinking. They challenged his beliefs and forced him to reexamine his assumptions about everything from the rights of an individual within society to what caused the sun to move across the sky.

During his studies with Oromis, Eragon learned the various climates and geographic regions in Alagaesia:

Oromis had devoted many of his lessons to the various climates and geographic regions that existed throughout Alagaesia. Thus, when Eragon left their camp to investigate the surrounding area, he was able to identify most of the plants he encountered.

Eragon figures out Sloan's true name. In the Eragon universe, knowing someone's true name gives you complete control over them, and it is one of the hardest things to do, whether you're finding your own name or someone else's:

Abandoning for the moment the question of punishment, Eragon considered what he knew about Sloan: the butcher's overriding love for Katrina----obsessive, selfish, and generally unhealthy as it was, although it had once been something wholesome----his hate and fear of the Spine, which were the offspring of his grief for his late wife, Ismira, who had fallen to her death among those cloud-rending peaks; his estrangement from the remaining branches of his family; his pride in his work; the stories Eragon had heard about Sloan's childhood; and Eragon's own knowledge of what it was like to love in Carvahall.

Eragon took that collection of scattered, fragmented insights and turned them over in his mind, pondering their significance. Like the pieces of a puzzle, he tried to fit them together. He rarely succeeded, but he persisted, and gradually he traced a myriad of connections between the events and emotions of Sloan's life, and thereby he wove a tangled web, the patterns of which represented who Sloan was. Throwing the last line of his web, Eragon felt as if he finally comprehended the reasons for Sloan's behavior. Because of that, he empathized with Sloan.

More than empathy, he felt he understood Sloan, that he had isolated the core elements of Sloan's personality, those things one could not remove without irrevocably changing the man. There occurred to him, then, three words in the ancient language that seemed to embody Sloan, and without thinking about it, Eragon whispered the words under his breath.

The sound could not have reached Sloan, yet he stirred----his hands gripping his thighs----and his expression became one of unease.

A cold tingle crawled down Eragon's left side, and goosebumps appeared on his arms and legs as he watched the butcher. He considered a number of different explanations for Sloan's reaction, each more elaborate than the last, but only one seemed plausible, and even it struck him as being unlikely. He whispered the trio of words again. As before, Sloan shifted in place, and Eragon heard him mutter,". . . someone walking on my grave."

Eragon released a shaky breath. It was difficult for him to believe, but his experiment left no room for doubt: he had, quite by accident, chanced upon Sloan's true name. The discovery left him rather bewildered. Knowing someone's true name was a weight responsibility, for it granted you absolute power over that person. Because of the inherent risks, the elves rarely revealed their true names, and when they did, it was only to those whom they trusted without reservation.

Eragon had never learned anyone's true name before. He had always expected that if he did, it would be as a gift from someone he cared about a great deal. Gaining Sloan's true name without his consent was a turn of events Eragon was unprepared for and uncertain how to deal with. It dawned upon Eragon that in order to guess Sloan's true name, he must understand the butcher better than he did himself, for he had not the slightest inkling what his own might be.

Through his readings during his time training with Oromis, Eragon learned a great many things, one of which was the culture of Urgals:

Many of the scrolls Oromis had assigned Eragon to read were devoted to the subject of Urgals, and one in particular, The Travels of Gnaevaldrskald, had taught him that the Urgals' entire culture was based upon feats of combat. Male Urgals could only improve their standing by raiding another village----whether Urgal, human, elf, or dwarf mattered little----or by fighting their rivals one on one, sometimes to the death. And when it came to picking a mate, Urgal females refused to consider a ram eligible unless he had defeated at least three opponents. As a result, each new generation of Urgals had no choice but to challenge their peers, challenge their elders, and scour the land for opportunities to prove their valor. The tradition was so deeply ingrained, every attempt to suppress it had failed.

After being given many memories from the Eldunari from Vreongard, Eragon knows how long large stones have been in a field as he is granted the knowledge of one of the ancient Dragons:

As he ate, he gazed out at the pleasant fields around the hill, watching the stir of air in the stalks of wheat and barley. Long, low walls of piled stone separated the fields; it must have taken the local farmers hundreds of years to dig so many stones out of the ground.

At least that wasn't a problem we had in Palancar Valley, he thought.

A moment later, one of the dragons' memories returned to him, and he knew exactly how old the stone walls were; they dated to the time when humans had come to live in the ruins of Illirea, after the elves had defeated King Palancar's warriors. He could see, as if he had been there, lines of men, women, and children combing over freshly tilled fields and carrying the rocks they found over to where the walls would be.

Telepathy

Being a Dragon Rider gives Eragon the power of telepathy, as it's his only way to talk to his dragon. He can also reach out with his consciousness and sense other organisms around him, feel the presences of other organisms, read memories, and feel the emotions and thoughts of other people.

Eragon senses a pack of rabbits and kills them with Death Word:

Less than a minute later, Eragon collected a brace of dead rabbits from their nest. It had taken him but an instant to locate the rabbits with his mind and then kill them with one of the twelve death words.

He telepathically calms a horse he is trying to buy without any formal training:

Eragon tried to put his hand on the bay like Brom had, but it shied away. He automatically reached out with his mind to reassure the horse, stiffening with surprise as he touched the animal's consciousness. The contact was not clear or sharp like it was with Saphira, but he could communicate with the bay to a limited degree. Tentatively, he made it understand that he was a friend. The horse calmed and looked at him with liquid brown eyes.

Brom then notes that it usually takes years of training for a Rider to contact anything other than their dragon:

Brom frowned. "It's unusual for one as young as you to have the ability. Most Riders had to train for years before they were strong enough to contact anything other than their dragon."

He spotted Cadoc a ways off, standing with his back to the wind. With his mind, Eragon instructed the horse to return to Brom.

Eragon tells his and Murtagh's horses to swim under a waterfall if they want to live:

Eragon reached out with his mind to force himself into the frightened thoughts of the horses. Using the ancient language, he told them that unless they swam through the waterfall, the would be killed and eaten by the Urgals. Though they did not understand everything he said, the meaning of his words was unmistakable.

Snowfire and Tornac tossed their heads, then dashed into the thundering downpour, whinnying as it struck their backs.

Eragon talks with Solembum, a werecat. Angela states that Eragon is only the third person who has been able to talk to him that has come to her store:

On a whim, Eragon reached out with his mind and touched the cat's consciousness. Gently, he prodded it with his thoughts, trying to make it understand that he was a friend.

You don't have to do that.

Eragon looked around in alarm. The cat ignored him and licked a paw. Saphira? Where are you? he asked. No one answered. Puzzled, he leaned against the counter and reached for what looked like a wood rod.

That wouldn't be wise.

Stop playing games, Saphira, he snapped, then picked up the rod. A shock of electricity exploded through his body, and he fell to the floor, writhing. The pain slowly faded, leaving him gasping for air. The cat jumped down and looked at him.

You aren't very smart for a Dragon Rider. I did warn you.

You said that! exclaimed Eragon. The cat yawned, then stretched and sauntered across the floor, weaving its way between objects.

Who else?

But you're just a cat! he objected.

[...]

The door to the shop swung open, letting in a beam of sunlight. Angel entered with a cloth bag full of plants. Her eyes flickered at Solembum and she looked startled. "He says you talked with him."

"You can talk with him, too?" asked Eragon. She tossed her head. "Of course, but that doesn't mean he'll say anything back." She set her plants on the counter, then walked behind it and faced him. "He likes you. That's unusual. Most of the time Solembum doesn't show himself to customers. In fact, he says that you show some promise, given a few years of work."

"Thanks."

"That's a compliment, coming from him. You're only the third person to come in here who has been able to speak with him."

Eragon contacts Arya's mind while she's in a catatonic state:

Eragon closed his eyes and extended a tendril of thought, like a probing finger, towards the elf's mind. He found it without difficulty. It was not fuzzy and filled with pain as he had anticipated, but lucid and clear, like a note from a crystal bell. Suddenly an icy dagger drove into his mind. Pain exploded behind his eyes with splashed of color. He recoiled from the attack but found himself held in an iron grip, unable to retreat.

Eragon fought as hard as he could and used every defense he could think of. The dagger stabbed into his mind again. He frantically threw his own barriers before it, blunting the attack. The pain was less excruciating than the first time, but it jarred his concentration. The elf took the opportunity to ruthlessly crush his defenses.

A stifling blanket pressed down on Eragon from all directions, smothering his thoughts. The overpowering force slowly contracted, squeezing the life out of him bit by bit, though he held on, unwilling to give up.

The elf tightened her relentless grip even more, so as to extinguish him like a snuffed candle. He desperately cried out in the ancient language, "Eka ai fricai un Shur'tugal!" I am a Rider and friend! The deadly embrace did not loosen its hold, but its constriction halted and surprise emanated from her.

Suspicion followed a second later, but he knew she would believe him; he could not have lied in the ancient language. However, while he had said he was a friend, that did not mean he meant her no harm. For all she knew, Eragon believed himself to be her friend, making the statement true for him, though she might not consider him one. The ancient language does have its limitations, thought Eragon, hoping that the elf would be curious enough to risk freeing him.

She was. The pressure lifted, and the barriers around her mind hesitantly lowered. The elf warily let their thoughts touch, like two wild animals meeting for the first time. A cold shiver ran down Eragon's side. Her mind was alien. It felt vast and powerful, weighted with memories of uncounted years. Dark thoughts loomed out of sight and touch, artifacts of her race that made him cringe when they brushed his consciousness. Yet through all the sensations shimmered a melody of wild, haunting beauty that embodied her identity.

What is your name? she asked, speaking in the ancient language. Her voice was weary and filled with quiet despair.

[...]

Arya withdrew from their contact. The unearthly strains that had echoed across their link were gone. Eragon took a shuddering breath and forced his eyes open. Murtagh and Saphira stood on either side of him, watching with concern. "Are you alright?" asked Murtagh. "You've been kneeling here for almost fifteen minutes."

"I have?" asked Eragon, blinking.

Yes, and grimacing like a pained gargoyle, commented Saphira dryly.

Eragon stood, wincing as his cramped knees stretched. "I talked with Arya!" Murtagh frowned quizzically, as if to inquire if he had gone mad. Eragon explained, "The elf----that's her name."

Eragon comes into contact with the minds of soldiers and people while flying over Surda:

As Saphira descended toward the inner ward of the castle, she brought Eragon into contact with the combined thoughts of the people in the capital. The noise overwhelmed him at first----how was he supposed to listen for foes and still function at the same time?----until he realized that, as usual, he was concentrating too much on specifics. All he had to do was sense people's general intentions. He broadened his focus, and the individual voices clamoring for his attention subsided into the continuum of the emotions surrounding him. It was like a sheet of water lay draped over the nearby landscape, undulating with the rise and fall of people's feelings and spiking whenever someone was racked by extremes of passion.

Thus, Eragon was aware of the alarm that gripped the people below as word of Saphira spread.

Eragon unconsciously catches the thoughts of a seneschal (guide):

While monitoring the minds around him, Eragon finds out that a man is planning to commit murder:

As Saphira was about to take off again, Eragon frowned; a note of discord had entered the minds he was monitoring. "Dahwar, two grooms in the stables have gotten into an argument and one of them, Tathal, intends to commit murder. You can stop him, though, if you send men right now."

Dahwar widened his eyes in an expression of astonishment, and even Orik twisted round to look at Eragon. The senechal asked, "How do you know this, Shadeslayer?"

Eragon merely said, "Because I am a Rider."

Eragon searches for the minds of magicians and the likes:

Eragon extended his awareness as far as he could in every direction, hunting for hostile minds that could feel his probing touch and would react to it----the minds of magicians and those trained to fend off magicians.

What he felt instead was the sudden panic that overwhelmed the Varden's sentinels, many of whom, he realized, had never before seen Saphira.

Eragon can look into people's memories:

As Eragon reached toward Garzhvog's consciousness, it reminded him of how the Twins invaded his mind when he first entered Farthen Dur. That observation was swept away as he immersed himself in the Urgal's identity. The very nature of his search----looking for malevolent intent perhaps hidden somewhere in Garzhvog's past----meant Eragon had to examine years of memories.

Eragon takes over an enemy soldier's mind and makes him sabotage catapults:

Extending himself, he found the mind of a soldier who tended one of the catapults. Though he was sure the soldier was defended by some magician, Eragon was able to gain dominance over him and direct his actions from afar. He guided the man up to the weapon, which was being loaded, then had him use his sword to hack at the skein of twisted rope that powered the machine. The rope was too thick to sever before the soldier was dragged away by his comrades, but the damage was already done. With a mighty crack, the partially wound skein broke, sending the arm of the catapult flying backward and injuring several men. His lips curled in a grim smile, Eragon proceeded to the next catapult and, in short order, disabled the remainder of the engines.

Eragon enters Sloan's mind and shows him his own memories:

Thrusting out with his mind, he engulfed Sloan's consciousness in his own and forced the butcher to accept memories that confirmed the truth of his statements. He also wanted Sloan to feel the power that was now his and to realize that he was no longer entirely human. And while Eragon was reluctant to admit it, he enjoyed having control over a man who had often made trouble for him and also tormented him with gibes, insulting both him and his family. He withdrew a half minute later.

Eragon contacts Solembum through the Varden camp:

Eragon reached out with his mind then, and searched through the camp until he found the distinctive feel of the werecat's mind. Solembum, he said, I need your help! Please come to my tent.

After a moment, he felt a grudging acknowledgement from the werecat, and he severed the contact.

Eragon knows how to defend himself against other telepathic attacks:

The congregation of priests began to howl and stomp their feet, and Eragon felt their minds clawing at his, like a pack of wolves tearing at a weakened deer. He retreated deep within himself, warding off the attacks with techniques he had been practicing under Glaedr's tutelage.

With the help of the Eldunari, Eragon is able to make telepathic contact with the Varden a little longer than a league (3 miles) away:

Eragon engages the Shade Varaug in a mental battle (credit to @brightsteel):

Knowing that Arya’s and Saphira’s lives were in peril stripped Eragon of every emotion, save that of implacable determination. His thoughts as sharp and clear as a shard of glass, he drove himself at the Shade’s seething consciousness. Varaug was too powerful, and the spirits that resided within him too disparate, for Eragon to overwhelm and control, so Eragon sought to isolate the Shade. He surrounded Varaug’s mind with his own: every time Varaug attempted to reach out toward Saphira or Arya, Eragon blocked the mental ray, and every time the Shade attempted to shift his body, Eragon counteracted the urge with a command of his own.

They battled at the speed of thought, fighting back and forth along the perimeter of the Shade’s mind, which was a landscape so jumbled and incoherent, Eragon feared it would drive him mad if he gazed at it for long. Eragon pushed himself to the utmost as he dueled with Varaug, striving to anticipate the Shade’s every move, but he knew that their contest could only end with his own defeat. As fast as he was, Eragon could not outthink the numerous intelligences contained within the Shade.

Eragon’s concentration eventually wavered, and Varaug seized upon the opportunity to force himself further into Eragon’s mind, trapping him . . . transfixing him . . . suppressing his thoughts until Eragon could do no more than stare at the Shade with dumb rage. An excruciating tingling filled Eragon’s limbs as the spirits raced through his body, coursing down every one of his nerves.

Awareness

Eragon was taught how to cast out his "awareness" all around his surroundings, which is akin to a field around himself and using his mental powers to locate the and keep track of any or all minds in that area. This power is closely related to "Telepathy", but I thought it better to put it in it's own category.

Eragon can cast out his thoughts, sensing any living being around him:

The day came when Eragon went to the glade beyond Oromis's hut, seated himself on the polished white stump in the center of the mossy hollow, and----when he opened his mind to observe the creatures around him----sensed not just the birds, beasts, and insects but also the plants of the forest.

The plants possessed a different type of consciousness than animals: slow, deliberate, and decentralized, but in their own way just as cognizant of their surroundings as Eragon himself was. The faint pulse of the plants' awareness bathed the galaxy of stars that wheeled behind his eyes----each bright spark representing a life----in a soft, omnipresent glow. Even the most barren soil teemed with organisms; the land itself was alive and sentient.

Intelligent life, he concluded, existed everywhere.

As Eragon immersed himself in the thoughts and feelings of the beings around him, he was able to attain a state of inner peace so profound that, during that time, he ceased to exist as an individual. He allowed himself to become a nonentity, a void, a receptacle for the voices of the world. Nothing escaped his attention, for his attention was focused on nothing.

He was the forest and its inhabitants.

Although Eragon did not study his surroundings in any great detail visually, he kept track of the minds of every living creature he was able to sense within a radius of several hundred feet, even down to the smallest spider crouched behind its web in the corner of a room, for Eragon had no desire to be surprised by anyone who might have cause to seek him out.

Even against a shielded mind, Eragon can spot his friends by the feel of their consciousness alone:

Eragon smiled and said, "Hello, Orik." He opened his eyes to see Orik clambering up the low knuckle of rock where he and Saphira sat. The dwarf, who was fully armored, carried his Urgal-horn bow in his left hand.

Hunkering beside Eragon,Orik wiped his brow and shook his head. "How'd you know it was me? I was shielding myself."

Every consciousness feels different, explained Saphira. Just like no two voices sound exactly the same.

Closing his eyes, Eragon slowly extended his consciousness outward, moving from the mind of one living thing to another, like tendrils of water seeping through sand. He touched teeming cities of insects frantically scurrying about their business, lizards and snakes hidden among warm rocks, diverse species of songbirds, and numerous small mammals. Insects and animals alike bustled with activity as they prepared for the fast-approaching night, whether by retreating to their various dens or, in the case of those of a nocturnal bent, by yawning, stretching, and otherwise readying themselves to hunt and forage.

Just as with his other senses, Eragon's ability to touch another being's thoughts diminished with distance. By the time his psychic probe arrived at the base of Helgrind, he could perceive only the largest of animals, and even those but faintly.

[...]

He proceeded with caution, ready to withdraw at a second's notice if he happened to brush against the minds of their prey: the Ra'zac and the Ra'zac's parents and steeds, the gigantic Lethrblaka.

[...]

Eragon searched long and hard. When he returned to himself, Roran was watching him with the expression of a starving wolf.

[...]

"I think I felt her," he said. "It's hard to be certain, because we're so far from Helgrind and I've never touched her mind before, but I think she's in that forsaken peak, concealed somewhere near the very top."

"Can you remember the name of the ancient language now, or is Galbatorix's magic still clouding your mind?"

"I can almost remember it, but . . . " Eragon shook his head with frustration.

Then Murtagh spoke the name of names twice: first to remove the spell of forgetfulness Galbatorix had placed on Eragon, and then again so that Eragon and Saphira might learn the name for themselves.

Brisingr (Fire)

Without any formal training, Eragon uses brisingr to defeat two Urgals, creating an explosive arrow in the process:

As he faced the Urgals, images flashed in his mind: dead villagers piled around the spear and an innocent baby who would never grow to adulthood. At the thought of their fate, a burning, fiery power gathered from every part of his body. It was more than a desire for justice. It was his entire being rebelling against the fact of death----that he would cease to exist. The power grew stronger and stronger until he felt ready to burst from the contained force.

He stood tall and straight, all fear gone. He raised his bow smoothly. The Urgals laughed and lifted their shields. Eragon sighted down the shaft, as he had done hundreds of times, and aligned the arrowhead with his target. The enemy inside him burned at an unbearable level. He had to release it, or it would consume him. A word suddenly leapt unbidden to his lips. He shot, yelling, "Brisingr!"

The arrow hissed through the air, glowing with a crackling blue light. It struck the lead Urgal on the forehead, and the air resounded with an explosion. A blue shock wave blasted out of the monster's head, killing the other Urgal instantly. It reached Eragon before he had time to react, and it passed through him without harm, dissipating against the houses.

Eragon kills the Shade Durza by lighting his sword on fire and plunging it through his heart:

Time seemed to slow as Eragon saw Durza tilt his head toward the ceiling. First shock, then anger contorted the Shade's face. Sneering defiantly, he raised his hand and pointed at Saphira, a word forming on his lips.

A hidden reserve of strength suddenly welled up inside Eragon, dredged from the deepest part of his being. His fingers curled around the hilt of his sword. He plunged through the barrier in his mind and took hold of the magic. All his pain and rage focused on one word:

"Brisingr!"

Zar'roc blazed with bloody light, heatless flames running along it. . .

He lunged forward. . .

And stabbed Durza in the heart.

Durza looked down with shock at the blade protruding from his heart. His mouth was open, but instead of words, an unearthly howl burst from him. His sword dropped from nerveless fingers. He grasped Zar'roc as if to pull it out, but it was lodged firmly in him.

Then Durza's skin turned transparent. Under it was neither flesh nor bone, but swirling patterns of darkness. He shrieked even louder as the darkness pulsated, splitting his skin. With one last cry, Durza was rent from head to toe, releasing the darkness, which separated into three entities who flew through Tronjheim's walls and out of Farthen Dur. The Shade was gone.

Eragon creates a small werelight to help see in the dark:

Reaching deep within himself to the place where he could touch the flow of magic, he uttered the words "Brisingr raudhr!"

He moved slightly, and the werelight mimicked his motion, as if connected to him by an invisible pole.

Geuloth du Knifr (Barrier)

Eragon creates a thin barrier around his sword so that he can spar with Brom without the fear of cutting him. First, here's Brom using it, as well as a description, then towards the end, Eragon uses it:

For a moment nothing happened, then he uttered, "Geuloth du knifr!" and a small red spark jumped between his fingers. As it flickered back and forth, he ran his fingers down the length of the sword. Then he twirled it and did the same thing on the other side. The spark vanished the moment his fingers left the metal.

Brom held his hand out, palm up, and slashed it with the sword. Eragon jumped forward but was too slow to stop him. He was astonished when Brom raised his unharmed hand with a smile. "What did you do?" asked Eragon.

"Feel the edge," said Brom. Eragon touched it and felt an invisible surface under his fingers. The barrier was about a quarter inch wide and very slippery. "Now do the same on Zar'roc," instructed Brom. "Your block will be a bit different than mine, but it should accomplish the same thing."

He told Eragon how to pronounce the words and coached him through the process. It took Eragon a few tries, but he soon had Zar'roc's edge protected.

Jierda (Break/Hit)

Eragon takes out 12 Urgals, man-like beasts who are over 8 feet tall, by creating piercing beams of light that struck the creatures and sent them flying back:

Rage swept through the Urgals; their leader howled, gnashing his teeth. "We'll drag you to him, then!" He waved his arm and the Urgals rushed at Saphira. Raising his right hand, Eragon barked, "Jierda!"

No! cried Saphira, but it was too late.

The monsters faltered as Eragon's palm glowed. Beams of light lanced from his hand, striking each of them in the gut. The Urgals were thrown through the air and smashed into trees, falling senseless to the ground.

Eragon breaks open a wooden door:

The patter of the Ra'zac's feet behind him made him quicken his pace until the hall abruptly ended with a closed door.

He pounded against it, trying to break it open, but the wood was too strong. The Ra'zac were nearly upon him. Frantic, he sucked in his breath and barked, "Jierda!" With a flash, the door splintered into pieces and fell to the floor.

Eragon uses jierda to untie ropes around his hands:

Eragon concentrated on the ropes that bound his wrists and reached for the magic. He hesitated, aware of Murtagh's eyes on him, then decided it didn't matter. "Jierda!" he grunted. The ropes snapped off his wrists. He rubbed his hands to get the blood flowing.

Using the energy in Aren, Eragon breaks apart rubble in front of city gates and sends it flying, while later transferring all of the rubble into a nearby lake. The rubble was so large that it would have taken 50 men days to move all of it:

Eragon drew in his breath, then he breached Aren's precious hoard and shouted, "Jierda!"

The torrent of energy that flowed through him was greater than any he had ever experienced; it was like an ice-cold river that burned and tingled with almost unbearable intensity. The sensation was both agonizing and ecstatic.

At his command, the huge pile of rubble blocking the gates erupted toward the sky in a solid pillar of earth and stone. The rubble struck Thorn in the side, shredding his wing and knocking the screeching dragon beyond the outskirts of Dras-Leona. Then the pillar spread outward, forming a loose canopy over the southern half of the city.

The launch of the rubble shook the square and drove everyone to the ground. Eragon landed on his hands and knees and remained there, staring upward as he maintained the spell.

When the energy in the ring was almost depleted, he whispered, "Ganga raehta." Like a dark thunderhead caught in a gale, the plume drifted to the right, in the direction of the docks and Leona Lake. Eragon continued to push the rubble away from the center of the city for as long as he could; then, as the last remnants of the energy coursed through him, he ended the spell.

With a deceptively soft sound, the cloud of debris collapsed inward. The heavier elements----the stones, the broken pieces of wood, and the clumps of dirt----fell straight down, pummeling the surface of the lake, while the smaller particles remained suspended in the air, forming a large brown smudge that slowly drifted farther west.

Where the rubble had been was now an empty crater. Broken paving stones edged the hollow, like a circle of shattered teeth. The gates to the city hung open, warped and splintered, damaged beyond repair.

Thrysta (Thrust/Compress)

Eragon helps collapse tunnels:

Breathing slowly, Eragon prepared to use magic. It might be possible to actually move all the dirt off the tunnel, but he needed to conserve his strength for later. Instead, he would try to collapse the tunnel by applying force to weak sections of its ceiling.

"Thrysta deloi," he whispered and sent tentacles of power into the soil. Almost immediately they encountered rock. He ignored it and reach further down until he felt the hollow emptiness of the tunnel. Then he began searching for flaws in the rock. Every time he found one, he pushed on it, elongating and widening it. It was strenuous work, but no more than it would have been to split the stone by hand. He made no visible progress----a fact that was not lost on the impatient dwarves.

Eragon persevered. Before long he was rewarded by a resounding crack that could be heard clearly on the surface. There was a persistent screech, then the ground slid inward like water draining from a tub, leaving a gaping hole seven yards across.

As the delighted dwarves walled off the tunnel with rubble, the sharp-nosed dwarf led Eragon to the next tunnel. This one was much more difficult to collapse, but he managed to duplicate the feat. Over the next few hours, he collapsed over a half-dozen tunnels throughout Farthen Dur, with Saphira's help.

Eragon uses a thrysta variation to push back enemies protected by wards against direct magical attacks:

He quickly readied a spell Murtagh had once used on him: "Thrysta vindr!" It was a roundabout way of striking at the men, as he was not actually hitting them but rather pushing the air against them. In any case, it worked.

A howl of wind filled the chamber, clawing at Eragon's hair and cloak and sending the men closest to him flying back into their compatriots, clearing a space of ten feet in front of him.

Waise heill (Heal)

With the help of Saphira, Eragon heals most of Brom's wounds from a knife stabbing him in between the ribs:

He peeled off his gloves while furiously searching his mind for the healing words Brom had taught him. Help me, Saphira, he implored. I am too weak to do this alone.

Saphira crouched next to him, fixing her eyes on Brom. I am here, Eragon. As her mind joined his, new strength infused his body. Eragon drew upon their combined power and focused it on the words. His hand trembled as he held it over the wound. "Waise heill!" he said. HIs palm glowed, and Brom's skin flowed together, as if it had never been broken. Murtagh watched the entire process.

It was over quickly. As the light vanished, Eragon sat, feeling sick. We've never done that before, he said.

Saphira nodded. Together we can cast spells that are beyond either of us.

Murtagh examined Brom's side and asked, "Is he completely healed?"

"I can only mend what is on the surface. I don't know enough to fix whatever's damaged inside."

Eragon spends hours healing Arya's various minor wounds:

As he gently laid a hand on the elf's spine, Saphira settled next to him, her glittering eyes fixed on the elf. He took a deep breath, then reached for the magic and started working.

He spoke the ancient words, "Waise heill!" A burn shimmered under his palm, and new, unmarked skin flowed over it, joining together without a scar. He passed over bruises or other wounds that were not life-threatening----healing them all would consume the energy he needed for more serious injuries. As Eragon toiled, he marveled that the elf was still alive. She had been repeatedly tortured to the edge of death with a precision that chilled him.

[...]

He labored through dawn, pausing only at brief intervals to eat and drink, trying to replenish himself from his fast, the escape, and now healing the elf. Saphira remained by his side, lending her strength where she could. The sun was well into the sky when he finally stood, groaning as his cramped muscles stretched. His hands were gray and his eyes felt dry and gritty.

Eragon heals a cut he received while shaving:

When he reached his chin, though, the razor slipped in his hand and cut him from the corner of his mouth to the underside of his jaw. He howled and dropped the razor, clapping his hand over the incision, which poured blood down his neck. Spitting the words past bared teeth, he said, "Waise heill." The pain quickly receded as magic knitted his flesh back together, though his heart still pounded from the shock.

Eragon heals a myriad of injuries on Saphira:

Eragon limped to Saphira's side, where he examined the crimson wound, glad that Oromis had given so many scrolls on anatomy to read. The blow----by claw or tooth, he was not sure----had torn the quadriceps muscle beneath Saphira's hide, but not so much as to bare the bone. Merely closing the surface of the wound, as Eragon had done so many times, would not be enough. The muscles had to be knitted back together.

The spell Eragon used was long and complex, and even he did not understand all its parts, for he had memorized it from an ancient text that offered little explanation beyond the statement that, given no bones were broken and the internal organs were whole, "this charm will heal any ailment of violent origins, excepting that of grim death." Once he uttered it, Eragon watched with fascination as Saphira's muscle writhed beneath his hand----veins, nerves, and fibers weaving together----and became whole once more.

Eragon heals soldiers after a battle:

Acquiescing, he bent down and mended a soldier's torn neck before moving on to one of the Varden. He made no distinction between friend and foe, treating both to the limit of his abilities.

As he healed a man's broken spine, a new way of viewing the situation occurred to him. . .

[...]

Kneeling by one of King Orrin's men, who had an arrow through the gut, Eragon grabbed his arms to stop him from writhing. "Easy now."

"Water," groaned the man. "For pity's sake, water. My throat is as dry as sand. Please, Shadeslayer." Sweat beaded his face.

Eragon smiled, trying to comfort him. "I can give you a drink now, but it'd be better if you wait until after I heal you. Can you wait? If you do, I promise you can have all the water you want."

"You promise, Shadeslayer?"

"I promise."

The man visibly struggled against another wave of agony before saying, "If I must."

With the aid of magic, Eragon drew out the shaft, then he and Saphira worked to repair the man's innards, using some of the warrior's own energy to fuel the spell. It took several minutes. Afterward, the man examined his belly, pressing his hands against the flawless skin, then gazed at Eragon, tears brimming in his eyes.

Eragon heals a woman's malignant tumor:

It was just after dawn and Eragon was sitting on his cot, oiling his mail hauberk, when one of the Varden's archers came to him and begged him to heal his wife, who was suffering from a malignant tumor. Even though he was supposed to be at Nasuada's pavilion in less than an hour, Eragon agreed and accompanied the man to his tent. Eragon found his wife much weakened from the growth, and it took all of his skill to extract the insidious tendrils from her flesh. The effort left him tired, but he was pleased that he was able to save the woman from a long and painful death.

Eragon manipulates stone to create a grave for Brom:

Eragon climbed onto the smooth hilltop, struggling because of his ribs. There, Murtagh lay Brom on the stone.

Eragon wiped his eyes and fixed his gaze on the sandstone. Gesturing with his hand, he said, "Moi stenr!" The stone rippled. It flowed like water, forming a body-length depression in the hilltop. Molding the sandstone like wet clay, he raised waist-high walls around it.

They laid Brom inside the unfinished sandstone vault with his staff and sword. Stepping back, Eragon again shaped the stone with magic. It joined over Brom's motionless face and flowed upward into a tall faceted spire.

Wards

Wards are a defensive magic that one uses to defend against enemy attacks. For example, if you said "Don't let any spear or sword hit me," then no spears or swords in battle would hurt you, as long as you had the energy to keep up the ward.

"Wards," said Oromis, "rely upon the strength of your body. If that strength is exceeded, you die. No matter how many wards you have, you will only be able to block attacks so long as your body can sustain the output of energy."

In these examples, Eragon's wards protect him from fireball debris fired from a catapult, arrows, a javelin fired from a ballista, and Thorn's fire breath, which killed other soldiers in moments:

Scry

A description of scrying:

Eragon srcys Saphira, Roran, and a girl from his dreams. The last one was thought to have been an impossible task:

He breathed deeply and closed his eyes. In his mind he formed a picture of Saphira, making it as lifelike as possible. It was more demanding than he expected. Then he said, "Draumr kopa!" and gazed at the water.

Its surface became completely flat, frozen by an invisible force. The reflections disappeared and the water became clear. On it shimmered an image of Saphira. Her surroundings were pure white, but Eragon could see that she was flying. Brom sat on her back, beard streaming, sword on his knees.

Eragon tiredly let the image fade. At least they're safe. He gave himself a few minutes to recuperate, then leaned back over the water. Roran, how are you? In his mind he saw his cousin clearly. Impulsively, he drew upon the magic and uttered the words.

The water grew still, then the image formed on its surface. Roran appeared, sitting on an invisible chair. Like Saphira, his surroundings were white. There were new lines on Roran's face----he looked more like Garrow than ever before. Eragon held the image in place as long as he could. Is Roran in Therinsford? He's certainly nowhere I've been.

The strain of using magic had brought beads of sweat to his forehead. He sighed and for a long time was content just to sit. Then an absurd notion struck him. What if I tried to scry something I created with my own imagination or saw in a dream? He smiled. Perhaps I'd be shown what my own consciousness looks like.

It was too tempting an idea to pass by. He knelt by the water once again. What shall I look for? He considered a few things, but discarded them all when he remembered his dream about the woman in the cell.

After fixing the scene in his mind, he spoke the words and watched the water intently. He waited, but nothing happened. Disappointed, he was about to release the magic when inky blackness swirled across the water, covering the surface. The image of a lone candle flickered in the darkness, brightening to illuminate a stone cell. The woman from his dream was curled up on a cot in one corner. She lifted her head, dark hair falling back, and stared directly at Eragon. He froze, the force of her gaze keeping him in place. Chills ran up his spine as their eyes locked. Then the woman trembled and collapsed limbly.

The water cleared. Eragon rocked back on his heels, gasping. "This can't be." She shouldn't be real; I only dreamed about her! How could she know I was looking at her? And how could I have scryed into a dungeon that I've never seen?

Source: Eragon

Eragon knows a variation of scrying where he can talk with the person he is scrying as well as see them:

He waited until the surface of the water became perfectly still----so that it acted like a mirror and he stood before what looked like a basin of stars----and then he said, "Draumr kopa," and many other words besides, reciting a spell that would allow him to not only see but speak with others at a distance. Oromis had taught him the variation on scrying two days before he and Saphira had left Ellesmera for Surda.

The water went completely black, as if someone had extinguished the stars like candles. A moment or two later, an oval shape brightened in the middle of the water and Eragon beheld the interior of a large white tent, illuminated by the flameless light from a red Erisdar, one of the elves' magical lanterns.

Normally, Eragon would be unable to scry a person or place he had not seen before, but the elves' seeing glass was enchanted to transmit an image of its surroundings to anyone who contacted the glass. Likewise, Eragon's spell would project an image of himself and his surroundings onto the surface of the glass. The arrangement allowed strangers to contact each other from any location in the world, which was an invaluable ability in times of war.

Eragon clamps another elf's legs, arms, and mouth shut:

Eragon's temper broke then, and he reached deep within himself and into the torrent of magic.

Drain

Eragon learns to draw energy from other living things to power his own spells instead of using his own reserves:

"I want you to extract a sphere of water from the stream, using only the energy you can gleam from the forest around you."

"Yes, Master."

As Eragon reached out to the nearby plants and animals, he felt Oromis's mind brush against his own, the elf watching and judging his progress.

[...]

He resumed the process, careful to avoid draining the elf's vitality, and when he was ready, commanded, "Up!"

Silent as the night, a sphere of water a foot wide rose from the brook until it floated at eye level across from Eragon. And while Eragon experienced the usual strain that results from intense effort, the spell itself caused him no fatigue.

The sphere was only in the air for a moment when a wave of death rolled through the smaller creatures Eragon was in contact with. A line of ants keeled over motionless. A baby mouse gasped and entered the void as it lost the strength to keep its heart beating. Countless plants withered and crumbled and became inert as dust.

Eragon drains the last vestiges of strength from a wounded horse to help his body with injuries and give him energy:

Then he transferred the horse's remaining vitality into himself and Saphira. It was not enough energy to restore all their strength, but it soothed their aching muscles and stopped their limbs from shaking.

Bending over his hands, he whispered, "Thaefathan."

The backs of his hands began to crawl and prickle as if he had fallen into a patch of stinging nettles. The sensation was so intense and so unpleasant, he longed to jump up and scratch himself as hard as he could. With an effort of will, he stayed where he was and watched as the skin on his knuckles bulged, forming a flat, whitish callus half an inch thick over each joint. They reminded him of the hornlike deposits that appear on the inside of horses' legs. When he was pleased with the size and density of the knobs, he released the flow of magic and set about exploring, by touch and sight, the mountainous new terrain that loomed over his fingers.

His hands were heavier and stiffer than before, but he could still move his fingers through their full range of motion. It may be ugly, he thought, rubbing the rough protuberances on his right hand against the palm of his left, and people may laugh and sneer if they notice, but I don't care, for it will serve its purpose and may keep me alive.

Miscellaneous

Below will be listed several spells that Eragon knows or has used that don't particularly fall into a single category or are just a school of study that Eragon has trained in.

While training with Oromis, Eragon manipulates water in many ways:

When Eragon got back on his feet, Oromis had him manipulate the water in various ways----shaping it into complex knots, changing the color of light that it absorbed or reflected, and freezing it in certain prescribed sequences----none of which proved difficult for him.

While training with Oromis, Eragon learns making, binding, summoning, and transmutation spells:

Night and day, Eragon strove to master his lessons. He memorized the words of making, binding, and summoning; learned the true names of plants and animals; and studied the perils of transmutation, how to call upon the wind and the sea, and the myriad skills needed to understand the forces of the world.

While training with Oromis, Eragon excelled at spells that had to do with light, heat, and magnetism:

At spells that dealt with the great energies----such as light, heat, and magnetism----he excelled, for he possessed the talent to judge nigh exactly how much strength a task required and whether it would exceed that of his body.

Eragon trains to lift a pebble in his palm:

"See this pebble?"

"Yes."

"Take it." Eragon did and stared at the unremarkable lump. It was a dull black, smooth, and as large as the end of his thumb. There were countless stones like it on the trail. "This is your training."

Eragon looked back at him, confused. "I don't understand."

"Of course you don't," Brom said impatiently. "That's why I'm teaching you and not the other way around. Now stop talking or we'll never get anywhere. What I want you to do is lift the rock off your palm and hold it in the air for as long as you can. The words you're going to use are stenr reisa. Say them."

"Stenr reisa."

"Good. Go ahead and try."

Eragon focused sourly on the pebble, searching his mind for any hint of the energy that had burned in him the day before. The stone remained motionless as he stared at it, sweating and frustrated. How am I supposed to do this? Finally, he crossed his arms and snapped, "This is impossible."

"No," said Brom gruffly. "I'll say when it's impossible or not. Fight for it! Don't give in this easily. Try again."

Frowning, Eragon closed his eyes, setting aside all distracting thoughts. He took a deep breath and reached into the farthest corners of his consciousness, trying to find where his power resided. Searching, he found only thoughts and memories until he felt something different----a small bump that was a part of him and yet not of him. Excited, he dug into it, seeking what it hid. He felt resistance, a barrier in his mind, but knew that the power lay on the other side. He tried to breach it, but it held firm before his efforts. Growing angry, Eragon drove into the barrier, ramming against it with all of his might until it shattered like a thin pane of glass, flooding his mind with a river of light.

"Stenr reisa," he gasped. The pebble wobbled into the air over his faintly glowing palm. He struggled to keep it floating, but the power slipped away and faded back behind the barrier. The pebble dropped to his hand with a soft plop, and his palm returned to normal. He felt a little tired, but grinned from success.

Oromis taught Eragon many ways to control energy such as light, heat, electricity, and gravity:

Study of the ancient language devoured the afternoon, whereupon they took up the practice of magic. Much of Oromis's lectures concerned the proper way in which to control various forms of energy, such as light, heat, electricity, and even gravity. He explained that since these forces consumed strength faster than any other type of spell, it was safer to find them already in existence in nature and then shape them with gramarye, instead of trying to create them from nothing.

Source: Eldest

Eragon is a fast learner, learning different words in the ancient language and swordsman skills very quickly:

The days followed the same pattern. First, Eragon struggled to learn the ancient words and to manipulate the pebble. Then, in the evening, he trained against Brom with the fake swords. Eragon was in constant discomfort, but he gradually began to change, almost without noticing. Soon the pebble no longer wobbled when he lifted it. He mastered the first exercises Brom gave him and undertook harder ones, and his knowledge of the ancient language grew.

In their sparring, Eragon gained confidence and speed, striking like a snake. His blows became heavier, and his arm no longer trembled when he warded off attacks. The clashes lasted longer as he learned how to fend off Brom.

Eragon can kill game with magic, mostly by firing a rock at the target:

Eragon also learned how to kill game with magic, which saved them time hunting. He would hold a small rock in his hand and shoot it at his prey. It was impossible to miss. The results of his efforts roasted over the fire each night.

Eragon uses a spell to hear a conversation (which is over a page long) between Brom and his friend Joed from rooms away:

It's not fair, he complained to himself. If only I could hear what they are saying. He jolted upright, electrified. Brom had once taught him some words that would enhance his hearing. Keen ears aren't exactly what I want, but I should be able to make the words work. After all, look what I could do with brisingr!

He concentrated intensely and reached for his power. Once it was within his grasp, he said, "Thverr stenr un atra eka horna!" and imbued the words with his will. As the power rushed out of him, he heard a faint whisper in his ears, but nothing more. Disappointed, he sank back, then started as Joed said, "----and I've been doing that for almost eight years now."

Eragon looked around. No one was there except for a few guards standing against the far wall of the keep. Grinning, he sat on the courtyard and closed his eyes.

Eragon uses his magic to unlock his cell door:

He was weak from his enforced fast, but his excitement overcame his hunger. Now for the real test. He reached out with his mind and felt the lock on the door. Instead of trying to break or cut it, he simply pushed its internal mechanism into the unlocked position. With a click, the door creaked inward.

Source: Eragon

Eragon summons water that was under the ground, up to the surface:

Though the ground was dry, the furrow he had made was lined with moisture. Curious, he scraped away more dirt and found a damp layer a few inches under the surface. "Look at this!" he said excitedly.

Saphira lowered her nose to his discovery. How does this help us? Water in the desert is sure to be buried so deeply we would have to dig for weeks to find it.

Yes, said Eragon delightedly, but as long as it's there, I can get it. Watch! He deepened the hole, then mentally accessed the magic. Instead of changing the dirt into water, he simply summoned forth the moisture that was already in the earth. With a faint trickle, water rushed into the hole. He smiled and sipped from it. The liquid was cool and pure, perfect for drinking.

Eragon uses magic to disperse a group of slavers:

Before the slavers could gather their senses, Eragon scrambled out of the commotion and raised his hands, invoking words in the ancient language. A globule of indigo fire struck the ground in the midst of the fray, bursting into a fountain of molten drops that dissipated like sun-warmed dew.

Eragon uses magic to make sure no one could eavesdrop on his and Nasuada's conversation:

Paranoia that they might be eavesdropped on gripped him. Reaching through the barrier in his mind, he delved into the magic and intoned: "Atra nosu waise vardo fra eld hornya. . . There, now we may speak without being overheard by man, dwarf, or elf."

Eragon uses magic to call back an arrow he fired:

Eragon fit shaft to string, aimed over the Az Ragni, and pulled back. The bow's draw length was less than two feet, but he was surprised to find that its weight far exceeded that of his own bow; he was barely strong enough to hold the string. He released the arrow and it vanished with a twang, only to reappear far above the river. Eragon watched with amazement as the arrow landed in a spray of water halfway across the Az Ragni.

He immediately reached through the barrier in his mind so that the magic's power suffused him and said, "Gath sem oro un lam iet." After a few seconds, the arrow darted back through the air to land on his outstretched palm.

Eragon uses magic to help him shave:

Eragon sat, glaring at the razor. Finally, he muttered, "Forget this." Composing himself, he reviewed his store of words from the ancient language, selected those that he needed, and then allowed his invented spell to roll off his tongue. A faint stream of black powder fell from his face as his stubble crumbled into dust, leaving his cheeks perfectly smooth.

Eragon uses magic to cook:

Oromis set many challenges before him. He had Eragon cook meals with magic, in order to teach him finer control of his gramarye; Eragon's first attempts resulted in a blackened mess.

Eragon can use magic to detect and neutralize poisons in his food:

The elf showed Eragon how to detect and neutralize poisons of every sort and, from then on, Eragon had to inspect his food for the different venoms Oromis was liable to slip into it.

Eragon can imbue matter with energy to be released at a later time or to give and object certain attributes:

Oromis devoted long hours to the craft of imbuing matter with energy, either to be released at a later time or to give an object certain attributes.

Eragon uses magic to float up on top of a high ridge:

Fixing his gaze on the crest of the monolith, Eragon gathered his strength, then said in the ancient language, "Up!"

He realized later that it he had not been accustomed to flying with Saphira, the experience might have proved unsettling enough to cause him to lose control of the spell and plunge to his death. The ground dropped away beneath his feet at a swift clip, while the tree trunks narrowed as he floated toward the underside of the canopy and the fading evening sky beyond. Branches clung like grasping fingers to his face and shoulders as he pushed through into the open. Unlike during one of Saphira's dives, he retained his sense of weight, as if he still stood upon the loam below.

Rising above the edge of the Stone of Broken Eggs, Eragon moved himself forward and released his grip on the magic, alighting upon a mossy patch.

Eragon places spells on a staff and Roran's hammer so that they won't break unless under the most extreme pressures:

That night, he had fortified both the knotted hawthorn and the handle to Roran's hammer with several spells that would prevent either piece from breaking, except under the most extreme stress.

Eragon talks about the different ways he can light a fire, which consisted of friction. summoning lightning, or concentrating sunbeams onto a single point:

"There are almost an infinite number of ways to do something with magic. For example, if I want to light a fire, I could light it with heat gathered from the air or the ground; I could create a flame out of pure energy; I could summon a bolt of lightning; I could concentrate a raft of sunbeams into a single point; I could use friction; and so forth."

Eragon talks about the possibilities and limitations of making someone "immortal":

"Can you make someone immortal with magic?" asked Roran.

"You can darken white hair, you can smooth wrinkles and remove cataracts, and if you are willing to go to extraordinary lengths, you can give a sixty-year old man the body he had at nineteen."

Source: Brisingr

Eragon uses magic to create a filter to protect him and Roran from the paralyzing effects of the Ra'zac's breath:

Eragon muttered a quick line in the ancient language. The drop in his strength that followed was almost imperceptible. "There. That will filter the air in front of us and protect us from the paralyzing effects of the Ra'zac's breath."

Source: Brisingr

Eragon casts a spell to temporarily blind a Lethrblaka:

He only had time for one more spell before he would have to devote himself to stopping the Ra'zac from inserting the sword between his liver and kidneys. In desperation, he gave up trying to directly harm the Lethrblaka and instead cried, "Garjzla, letta!"

It was a crude spell, constructed in haste and poorly worded, yet it worked. The bulbous eyes of the Lethrblaka with the broken wing became a matched set of mirrors, each a perfect hemisphere, as Eragon's magic reflected the light that otherwise would have entered the Ltherblaka's pupils. Blind, the creature stumbled and flailed at the air in a vain attempt to hit Saphira.

Eragon casts a spell so that only Roran or himself can open Katrina's cell door:

Closing his eyes, Eragon located the minds of the prisoners in Helgrind, muttered a burst of the ancient langauge, then said to Roran, "I sealed off Katrina's cell so the Ra'zac can't use her as a hostage. Only you and I can open the door now."

Source: Brisingr

Eragon casts a bright red light that illuminates a whole room:

He recoiled against the wall, shoving Roran back. At the same time, something augered past his face, carving a groove of flesh from his right cheek. The thin trench burned as if cauterized.

"Kveykva!" shouted Eragon.

Red light, bright as the midday sun, flared into existence. It had no source, and thus it illuminated every surface evenly and without shadows, giving things a curious flat appearance. The sudden blaze dazzled Eragon, but it did more than that to the lone Ra'zac in front of him; the creature dropped its bow, covered its hooded face, and screamed high and shrill.

Source: Brisingr

Eragon knows incantations to find out whether or not there are other spells cast on Katrina:

"Just look into my eyes," he told her. She nodded and obeyed.

That was the first time Eragon had a reason to use the spells Oromis had taught him for detecting the work of another spellcaster, and he had difficulty remembering every word from the scrolls on Ellesmera.

Eragon floats down to a ledge a hundred feet below him with a spell:

Securing his hold on Sloan, Eragon fixed his eyes on a narrow ledge about a hundred feet below. This is going to hurt, he thought, preparing himself for the attempt. Then he barked, "Audr!"

Eragon felt himself rise several inches above the floor of the cave. "Fram," he said, and the spell propelled him away from Helgrind and into open space, where he hung unsupported, like a cloud drifting in the sky. Accustomed as he was to flying with Saphira, the sight of nothing but thin air underneath his feet still caused him unease.

By manipulating the flow of magic, Eragon quickly descended from the Ra'zac's lair----which the insubstantial wall of stone once again hid----to the ledge. His boot slipped on a loose piece of rock as he alighted. For a handful of breathless seconds, he flailed, searching for solid footing but unable to look down, as tilting his head could send him toppling forward. He yelped as his left leg went off the ledge and he began to fall. Before he could resort to magic to save himself, he came to an abrupt halt as his left foot wedged itself in a crevice. The edges of the rift dug into his calf behind his greave, but he did not mind, for it held him in place.

Eragon leaned his back against Helgrind, using it to help him prop up Sloan's limp body. "That wasn't so bad," he observed.

Source: Brisingr

Eragon casts spells on Sloan to make him walk all the way to Du Weldenvarden from Helgrind (through a huge desert and across many miles), makes him walk all the way there without allowing him to change course or else an itch will start and grow, and allows animals to come give him aid when he needs it:

"Furthermore, I will lay upon you a compulsion to travel northward until you reach the elf city of Ellesmera, which stands deep in the heart of Du Weldenvarden. You can try to resist the urge if you want, but no matter how long you fight it, the spell will irritate you like an unscratched itch until you obey its demands and travel to the elves' realm."

[...]

"Wherever you go, you shall not want food, nor will wild animals attack you. I will place certain enchantments around you that will keep men and beasts from troubling you and will cause animals to bring you sustenance when you need it."

[...]

And when they were finished with the oaths, Eragon cast five spells that would drive Sloan toward Ellesmera, would protect him from unprovoked violence, and would entice the birds and the beasts and the fish that dwelled in the rivers and lakes to feed him. Eragon fashioned the spells so they would derive their energy from Sloan and not himself.

Source: Brisingr

Here's a map showing the distance Sloan had to walk:

Eragon uses a spell to make himself invisible to an enemy soldier:

As the soldier approached his location, spurs clinking, Eragon began to whisper a complex spell in the ancient language. The words poured off his tongue in an unbroken stream, until, to his alarm, he mispronounced a particularly difficult cluster of vowels and had to start the incantation anew.

The soldier took another step toward him.

And another.

Just as the soldier paused in front of him, Eragon completed the spell and felt his strength ebb as the magic took effect. He was an instant too late, however, to completely escape detection, for the soldier exclaimed, "Aha!" and brushed aside the branches, exposing Eragon.

Eragon did not move.

The soldier peered directly at him and frowned.

"What the . . . ," he muttered. He jabbed his spear into the thicket, missing Eragon's face by less than an inch. Eragon dug his nails into his palms as a tremor racked his clenched muscles. "Ah, blast it," said the soldier, and released the branches, which sprang back to their original positions, hiding Eragon once more.

"What was it?" called another of the men.

"Nothing," said the soldier, returning to his companions. He removed his helmet and wiped his brow. "My eyes are playing tricks on me."

Source: Brisingr

Description of the spell:

The spell he had used contained two parts: the first bent rays of light around his body so he appeared invisible, and the second hopefully prevented other spellweavers from detecting his use of magic. The spell's main drawbacks were that it could not conceal footprints----therefore one had to remain stone-still while using it----and it often failed to completely eliminate a person's shadow.

Eragon sings a flower to life:

Eager to lighten her burden however he could, Eragon glanced about the ground nearest him and then murmured so softly as to be inaudible, "Loivissa." Guided by the power of the true name, he shifted through the earth by his feet until his fingers closed upon what he sought: a thin, papery disk half the size of his smallest fingernail. Holding his breath, he deposited it in his right palm, centering it over his gedway ignasia with as much delicacy as he could muster. He reviewed what Oromis had taught him concerning the sort of spell he was about to cast to ensure he would not make a mistake, and then he began to sing after the fashion of he elves, smooth and flowing:

Eldhrimmer O Loivissa nuanen, dautr abr deloi,

Eldhrimmer nen ono weohnatai medh solus un thringa,

Eldhrimmer un fortha onr feon vara,

Wiol allr sjon.

Eldhrimmer O Loivissa nuanen . . .

Again and again, Eragon repeated the same four lines, directing them toward the brown flake in his hand. The flake trembled and then swelled and bulged, becoming spherical. White tendrils an inch or two long sprouted from the bottom of the peeling globe, tickling Eragon, while a thin green stem poked its way out of the tip and, at his urging, shot nearly a foot in the air. A single leaf, broad and flat, grew from the side of the stem. Then the tip of the stem thickened, drooped, and, after a moment of seeming inactivity, split into five segments that expanded outward to reveal the waxy petals of a deep-throated lily. The flower was pale blue and shaped like a bell.

When it reached its full size, Eragon released the magic and examined his handiwork. Singing plants into shape was a skill most every elf mastered at an early age, but it was one Eragon had practiced only a few times, and he had been uncertain whether his efforts would meet him with success. The spell had exacted a heavy toll from him; the lily required a surprising amount of energy to feed what was the equivalent of a year and a half of growth.

Eragon uses a spell to return Murtagh's sword to it's undamaged form:

As he gazed at the silver steel, Eragon composed a spell that would smooth the wrinkles from the blade, close the wedge-shaped gaps along the edges, and restore the strength of the temper.

Eragon uses magic to mine/bring forth gold from the ground:

He strode through the camp until he found a large square of open space where thirty-some Varden were practicing with a wide assortment of weapons. To his relief, they were too busy training to notice his presence. Crouching, he lay his right hand palm-upward on the trampled earth. He chose the words he would need from the ancient language, then murmured, "Kuldr, risa lam iet un malthinae unin bollr."

The soild beside his hand appeared unchanged, although he could feel the spell sifting through the dirt for hundreds of feet in every direction. Not more than five seconds later, the surface of the earth began to boil like a pot of water left to sit for too long over a high flame, and it acquired a bright yellow sheen. Eragon had learned from Oromis that wherever one went, the land was sure to contain minute particles of nearly every element, and while they would be too small and scattered to mine with traditional methods, a knowledgeable magician could, with great effort, extract them.

From the center of the yellow pouch, a fountain of sparkling dust arched up and over, landing in the middle of Eragon's palm. There each glittering mote melded into the next, until three spheres of pure gold, each the size of a large hazelnut, rested on his hand.

Source: Brisingr

Eragon enchants two rings for Roran and Katrina:

From the pouch at his belt, Eragon withdrew two plain gold rings, polished until they shone. The previous night, he had molded them out of the last of the gold orbs he had extracted from the earth. He handed the larger one to Roran and the smaller one to Katrina.

Roran turned his ring, examining it, then held it up against the sky, squinting at the glyphs in the ancient language carved into the inside of the band. "It's very nice, but how can these help protect us?"

"I enchanted them to do three things," said Eragon. "If you ever need my help, or Saphira's, twist the ring once around your finger and say, 'Help me, Shadeslayer; help me, Brightscales,' and we will hear you, and we will come as fast as we can. Also, if either of you is close to death, your ring will alert us and you, Roran, or you, Katrina, depending on who is in peril. And so long as the rings are touching your skin, you will always know how to find each other, no matter how far apart you may be."

Without the use of words, Eragon uses magic to pull three dwarf guards toward him and away from danger:

As the first word rang in his throat, three of the strange dwarves grabbed the hindmost of Eragon's guards and lifted their glimmering daggers to stab him. Faster than speech or conscious thought, Eragon plunged his whole being into the flow of magic and, without relying upon the ancient language to structure his spell, rewove the fabric of the world into a pattern more pleasing to him. The three guards who stood between him and the attackers flew toward him, as if yanked by invisible strings, and landed upon their feet beside him, unharmed but disoriented.

Eragon uses a spell to ensure that the cold wind doesn't chill him even more while flying with Saphira:

Eragon protected himself against the freezing temperatures by wearing several layers of clothes and by shielding himself from the wind with a spell that split the stream of freezing air so it flowed harmlessly to either side.

Source: Brisingr

Eragon can use magic to transport objects:

While the two dragons danced among the clouds, Oromis taught Eragon how a magician could transport an object from one place to another without having the object traverse the intervening distance. "Most forms of magic," said Oromis, "require ever more energy to sustain as the distance between you and your target increases. However, that is not the case in this particular instance. It would require the same amount of energy to send the rock in my hand to the other side of that stream as it would to send it all the way to the Southern Isles. For that reason, the spell is most useful when you need to transport an item with magic across a distance so vast, it would kill you to move it normally through space. Even so, it is a demanding spell, and you should only resort to it if all else has failed. To shift something as large as Saphira's egg, for example, would leave you too exhausted to move."

Then Oromis taught Eragon the wording of the spell and several variations on it. Once he had memorized the incantations to Oromis's satisfaction, the elf had him attempt to shift the small rock he was holding.

As soon as Eragon uttered the spell in its entirety, the rock vanished from the palm of Oromis's hand and, an instant later, reappeared in the middle of the clearing with a flash of blue light, a loud detonation, and a surge of burning hot air. Eragon flinched from the noise and then gripped the branch of a nearby tree to steady himself as his knees buckled and cold crept over his limbs. His scalp tingled as he gazed at the rock, which lay in a circle of charred and flattened grass, and he remembered the moment when he had first beheld Saphira's egg.

Eragon disperses an area of smoke:

"Vaetna," he gasped, and waved his hand. With a sound like rustling silk, the thick gray dust parted, leaving the center of the courtyard clear.

Eragon uses magic to summon the true form of his sword Brisingr, creating a literal copy:

Eragon took a moment to collect himself. Then he found the nub in the back of his mind and reached into the word he spoke, while also thinking about everything he knew of the sword, he said clearly and distinctly:

"Brisingr!"

Eragon felt his strength ebb precipitously. Alarmed, he tried to speak, tried to move, but the spell bound him in place. He could not even blink or breathe.

Unlike before, the sheathed sword did not burst into flame; it wavered, like a reflection in water. Then, in he air next to the weapon, a transparent apparition appeared: a perfect, glowing likeness of Brisingr free of its sheath. As well made as was the sword itself----and Eragon had never found so much as a single flaw----the duplicate floating before him was even more refined. It was as if he was seeing the idea of the sword, an idea that not even Rhunon, with all her experience working metal, could hope to capture.

As soon as the manifestation became visible, Eragon was again able to breathe and move. He maintained the spell for several seconds, so he could marvel at the beauty of the summoning, and then he let the spell slip free of his grasp and the ghostly sword slowly faded into oblivion.

Source: Inheritance

Eragon lights a lantern:

He went to the lantern that hung from the pole in the center of the tent and murmured, "Istalri," not using brisingr, so as to avoid igniting his sword. The resulting flame filled the interior with a warm, steady light that made the sparsely furnished army tent seem almost cozy.

Eragon stops himself in midair with a spell:

Even as he fell, he made sure to maintain his grasp on Brisingr and to keep the blade well away from his body; wards or no wards, the sword could still injure him, due to Rhunon's spellwork.

Little one!

"Letta!" Eragon shouted, and with a jolt, he stopped dead in the air, no more than ten feet above the ground.

Eragon launches himself in the air with a spell:

Eragon took a half step forward, as if to stop her, then cursed and growled, "Audr!"

Eragon knows a spell that makes Saphira invisible from below while she's flying:

----but after circling the camp a few times, Saphira would fly into a cloud, and Eragon would cast a spell that would render her invisible to those watching from below.

Eragon can protect himself from the cold with magic:

From the Varden's camp by the banks of Leona Lake, Saphira set out across the broad expanse of water, angling northwest and climbing so high that Eragon had to use a spell to shield himself from the cold.

Eragon knows a spell that will let him know how close he is to the ground or water while flying with Saphira:

He also cast a spell that Oromis had taught him, a spell that informed him and Saphira exactly how close they were to the water----or to the ground----at any given moment.

Eragon knows a spell that allows him to filter water away from him when its raining:

From the moment they entered the cloud, the ever-present moisture began to accumulate on Eragon's skin and soak into his woolen clothes, weighing them down. It was an annoyance he could have ignored had not the combination of water and wind been so chilling, it would have soon drained the heat from his limbs and killed him. Therefore, he cast another spell, which filtered the air around him of any visible droplets, as well as----at her request----the air around Saphira's eyes, for the moisture kept collecting on their surface, forcing her to blink all too frequently.

Glaedr teaches Eragon a spell that allows him to warm himself, Saphira, and Glaedr against the freezing cold, as well as trap air around themselves so that they could breathe, as well as allow stale air to escape from the bubble he created:

Eragon, you must amend the spell you are using to warm yourself to include Saphira and me. It is going to grow cold, colder than even the bitterest winter in the Spine, and without magic, we shall freeze to death.

Even you?

I will crack like a piece of hot glass dropped in snow. Next you must cast a spell to gather the air around you and Saphira and to hold it there, so you may still breathe. But it must also allow the stale air to escape, or else you will suffocate. The wording of the spell is complicated, and you must not make any mistakes, so listen carefully. It goes as such----

Once Glaedr had recited the necessary phrases in the ancient language, Eragon repeated them back to him, and when the dragon was satisfied with his pronunciation, Eragon cast the spell. Then he amended his other piece of magic as Glaedr had instructed, so the three of them were shielded from the cold.

Source: Inheritance

Glaedr teaches Eragon a spell that protects him from the strange poison on Vreongard:

Eragon, you must cast another spell. The wording of it goes thus---- And he uttered several lines in the ancient language. It was an odd spell; the phrasing was obscure and convoluted, and Eragon was unable to determine what it was supposed to accomplish.

When he asked Glaedr, the old dragon said, There is an invisible poison here, in the air you breathe, in the ground you walk upon, and in the food you may eat and the water you may drink. The spell will protect us against it.

Eragon can use magic to increase his eyesight:

Eragon continued to study the valley, comparing it to what Glaedr had shown him, and he frowned when he saw a line of bobbing lights----lanterns, he thought----within the abandoned city. He whispered a spell to sharpen his sight and was able to make out a line of hooded figures in dark robes walking slowly through the ruins.

Eragon uses a spell to catch himself from a 300 foot fall and land softly on he ground:

Keeping his arms outstretched, he stood atop the pillar, and then he tipped forward and fell headfirst toward the ground. Just before he struck, he said, "Veoht," and he slowed, rotated, and alit upon the cracked stone as gently as if he were stepping out of a carriage.

Umaroth teaches Eragon a spell where he can store the 130-something Eldunari in his possession in a sort of "pocket dimension," which will always be at a set place behind him and allows him to talk to and call upon the dragons and their strength still:

At last Umaroth said, This is a lesson for another time. You know what the spell is supposed to do, if not how. That will have to suffice. Take from us the strength needed and cast it, and then let us be off.

Nervous, Eragon fixed the words of the spell in his mind to avoid making mistakes, and then he began to speak. As he uttered the lines, he drew upon the reserves of the Eldunari, and his skin tingled as an enormous rush of energy poured through him, like a river of water both hot and cold.

The air around the uneven pile of Eldunari rippled and shimmered; then the pile seemed to fold in on itself and it winked out of sight. A gust of wind tousled Eragon's hair, and a soft, dull thud echoed throughout the chamber.

Astonished, Eragon watched as Saphira pushed her head forward and swung it through the spot where the Eldunari had just been. They had disappeared, completely and utterly, as if they had never existed, and yet he and she could still feel the dragons' minds close at hand.

Once you leave the vault, said Umaroth, the entrance to this pocket of space will remain at a fixed distance above and behind you at all times, save when you are in a confined area or when a person's body should happen to pass through that space. The entrance is no longer than a pinprick, but it is more deadly than any sword; it would cut right through your flesh were you to touch it.

Eragon uses a transporting spell to embed 12 swords into a wall to prevent a trap from triggering:

Summoning the words he needed, Eragon cast the first of the twelve spells he intended to use. One of the elves' swords----Laufin's, he thought----disappeared with a faint breath of wind, like a tunic being swung through the air. A half second later, a solid thud emanated from the wall to their left.

Eragon smiled. It had worked. If he tried to send the sword through the sheet of metal, the reaction would have been substantially more dramatic.

Speaking faster than before, he cast the rest of the spells, embedding six swords within each wall, each sword five feet from the next. The elves watched him intently as he spoke; if the loss of their weapons upset them, they did not show it.

Eragon uses an empathy spell on Galbatorix, making the King feel all the suffering and hurt he has caused since he was born, and Galbatorix is over a hundred years old. The spell drove the king so mad, he ended up casting a suicide spell:

Eragon cried out, and in his desperation he reached for Saphira and the Eldunari----their minds beseiged by the crazed dragons of Galbatorix's command----and without intending to, he drew from their stores of energy.

And with that energy, he cast a spell.

It was a spell without words, for Galbatorix's magic would not allow otherwise, and no words could have described what Eragon wanted, nor what he felt. A library of books would have been insufficient to the task. His was a spell of instinct and emotion; language could not contain it.

What he wanted was both simple and complex: he wanted Galbatorix to understand . . . to understand the wrongness of his actions. If Eragon was going to spend the rest of his life as a slave to the king, then he wanted Galbatorix to comprehend what he had done, fully and completely.

As the magic took effect, Eragon felt Umaroth and the Eldunari turn their attention to his spell, fighting to ignore Galbatorix's dragons. A hundred years of inconsolable grief and anger welled up with the Eldunari, like a roaring wave, and the dragons melded their minds with Eragon's and began to alter the spell, deepening it, widening it, and building upon it until it encompassed far more than he originally intended.

Not only would the spell show Galbatorix the wrongness of his actions; now it would also compel him to experience all the feelings, both good and bad, that he had aroused in others since the day he had been born. The spell was beyond any Eragon could have invented on his own, for it contained more than a single person, or a single dragon, could conceive of. Each Eldunari contributed to the enchantment, and the sum of their contribution was a spell that extended not only across the whole of Alagaesia but also back through every moment in time between then and Galbatorix's birth.

It was, Eragon thought, the greatest piece of magic the dragons had ever wrought, and he was their instrument; he was their weapon.

The power of the Eldunari rushed through him, like a river as wide as an ocean, and he felt a hollow and fragile vessel, as if his skin might tear with the force of the torrent he channeled. If not for Saphira and the other dragons, he would have died in an instant, drained of all strength by the voracious demands of the magic.

[...]

The lines of Galbatorix's face deepened, and his eyes began to bulge from their sockets. "What have you done?" he said, his voice hollow and strained. He stepped back and put his fists to his temples. "What have you done!"

With an effort, Eragon said, "Made you understand."

With the help of the Eldunari, Eragon uses a spell to drag himself, Arya, Elva, Thorn, Murtagh, two children, and Saphira to a stone slab carrying Nasuada, and then casts a spell to protect them from any harm caused by Galbatorix's suicide spell:

Eragon had no time for words. Again drawing upon the Eldunari, he cast a spell to drag himself, Saphira, Arya, Elva, Thorn, and Murtagh, and the two children on the dias over to the block of stone where Nasuada was chained. And he also cast a spell to stop or deflect whatever might harm them.

They were only halfway to the block when Galbatorix vanished in a flash of light brighter than the sun. Then all went black and silent as Eragon's protective spell took effect.

Description of the blast:

The ground rumbled and shook; then the front of the citadel exploded outward in a wall of white and yellow flame so bright, Roran saw the bones within the archer's neck and head, his flesh like a red gooseberry held before a candle.

[...]

The walls of the room were cracked, and the pillars, carvings, and lanterns had been pulverized. At the back of the chamber lay Shruikan's corpse, much of the flesh stripped from his soot-blackened bones. At the front, the explosion had shattered the stone walls, as well as the walls beyond for hundreds of feet, exposing a veritable warren of tunnels and rooms. The beautiful golden doors that had guarded the entrance to the chamber had been blown off their hinges, and Eragon thought he glimpsed daylight at the far end of the quarter-mile-long hallway that led to the outside.

[...]

Piles of broken stone covered the floor along much of the hallway, which slowed the dragons. To either side, Eragon could see into the rubble-filled rooms and tunnels that the explosion had torn open. Within them, tables, chairs, and other pieces of furniture burned. The limbs of the dead and dying stuck out at odd angles from beneath the tumbled stones, occasionally a grimy face or the back of a head.

[...]

As they emerged from the citadel, the air cleared and Eragon was able to see the destruction that the blast had wreaked on Uru'baen. It had ripped off the slate roofs of many nearby buildings and set fire to the beams underneath. Scores of fires dotted the rest of the city.

Using the name of the ancient language, Eragon dismantles the spells Galbatorix set up and around Uru'baen:

Before he had joined in the effort to heal and place wards or protection around everyone in and around Uru'baen, he had spent over an hour using the name of the ancient language to find and dismantle the many spells Galbatorix had bound to the buildings and the people of the city. Some of the enchantments seemed benign, even helpful----such as one spell whose only apparent purpose was to keep the hinges of a door from creaking, and which drew its power from an egg-sized piece of crystal set within the face of the door----but Eragon dared not leave any of the king's spells intact, no matter how harmless they appeared. Especially not those that lay upon the men and women of Galbatorix's command. Among them, oaths of fealty were the most common, but there were also wards enchantments to grant skills beyond the ordinary, and other, more mysterious spells.

Premonition

Brief "description" of a premonition in the Eragon universe:

"It's a mystery, then, how people can have premonitions while sleeping, how they do something unconsciously that has defeated our greatest sages. Premonitions may be linked to the very nature and fabric of magic . . . or they may function in a similar way to the dragons' ancestral memories. We don't know."

Eragon has a premonition, or a look into the future, of a battle to come:

Slumber soon took him. Most of his rest was uneventful, but right before he woke, the usual night phantasms were replaced with a vision as clear and vibrant as any waking experience.

He saw a tortured sky, black and crimson with smoke. Crows and eagles swirled high above the flights of arrows that arched from one side to another of a great battle. A man sprawled in the clotted mud with a dented helm and bloody mail----his face concealed behind an upthrown arm.

An armored hand entered Eragon's view. The gauntlet was so near it blotted out half the world with polished steel. Like an inexorable machine, the thumb and last three fingers curled into a fist, leaving the trunk of the index finger to point at the downed man with all the authority of fate itself.

Swordsmanship

Brom describes Eragon as a talented and rare swordsman:

Brom shook his head. "I can teach you nothing more of the sword. Of all the fighters I've met, only three of them could have defeated me like that, and I doubt any of them could have done it with their left hand." He smiled ruefully. "I may not be as young as I used to be, but I can tell that you're a talented and rare swordsman."

Eragon defeats Brom in a duel, only using his left hand (his off hand) because his right hand is still recovering from being broken:

Eragon swooped down, grabbed the stick, and hurled it at Brom. The splint got in his way, though, and Brom easily sidestepped the piece of wood. The old man rushed forward, swinging his sword. Eragon ducked just as the blade whistled over his head. He growled and tackled Brom ferociously.

They pitched to the ground, each struggling to stay on top. Eragon rolled to the side and swept Zar'roc over the ground at Brom's shins. Brom parried the blow with the hilt of his sword, then jumped to his feet. Twisting as he stood, Eragon attacked again, guiding Zar'roc through a complex pattern. Sparks danced from their blades as they struck again and again. Brom blocked each blow, his face tight with concentration. But Eragon could tell that he was tiring. The relentless hammering continued as each sought as opening in the other's defenses.

Then Eragon felt the battle change. Blow by blow he gained advantage; Brom's parries slowed and he lost ground. Eragon easily blocked a stab from Brom. Veins pulsed on the old man's forehead and cords bulged in his neck from the effort.

Suddenly confident, Eragon swung Zar'roc faster than ever, weaving a web of steel around Brom's sword. With a burst of speed, he smashed the flat of his blade against Brom's guard and knocked the sword to the ground. Before Brom could react, Eragon flicked Zar'roc up to his throat.

Eragon spars evenly with Murtagh, even though Murtagh has been studying swordplay all of his life as compared to the few months Eragon has:

Eragon safed Zar'roc, settled into a crouch, then swung at Murtagh's shoulder. Their swords met in midair. Eragon disengaged with a flourish, thrust, and then riposted as Murtagh parried, dancing away.

He's fast! thought Eragon.

They struggled back and forth, trying to batter each other down. After a particularly intense series of blows, Murtagh started laughing. Not only was it impossible for either of them to gain an advantage, but they were so evenly matched that they tired at the same rate. Acknowledging with grins each other's skill, they fought on until their arms were leaden and sweat poured off their sides.

Finally Eragon called, "Enough, halt!" Murtagh stopped in midblow and sat down with a gasp. Eragon staggered to the ground, his chest heaving. None of his fights with Brom had been this fierce.

Eragon duels Arya, even though he is somewhat tired from running magic exercises, and manages to impress her with his skill:

They faced each other across the circle of warriors. Arya drew her sword with her left hand. The weapon was thinner than Eragon's, but just as long and sharp. He slid Zar'roc out of its polished sheath and held the red blade point-down by his side. For a long moment they stood motionless, elf and human watching each other. It flashed though Eragon's mind that this was how many of his fights with Brom had started.

He moved forward cautiously. With a blur of motion Arya jumped at him, slashing at his ribs. Eragon reflexively parried the attack, and their swords met in a shower of sparks. Zar'roc was bated aside as if it were no more than a fly. The elf did not take advantage of the opening, however, but spun to her right, hair whipping through the air, and struck at his other side. He barely stopped the blow and backpedaled frantically, stunned by her ferocity and speed.

Belatedly, Eragon remembered Brom's warning that even the weakest elf could easily overpower a human. He had about as much chance at defeating Arya as he did Durza. She attacked again, swinging at his head. He ducked under the razor-sharp edge. But then why was she . . . toying with him? For a few long seconds he was too busy warding her off to think about it, then he realized, She wants to know how proficient I am.

Understanding that, he began the most complicated series of attacks he knew. He flowed from one pose to another, recklessly combining and modifying them in every possible way. But no matter how inventive he was, Arya's sword always stopped his. She matched his actions with effortless grace.

Engaged in a fiery dance, their bodies were linked and separated by the flashing blades. At times they nearly touched, taut skin only a hair's breath away, but then momentum would whirl them apart, and they would withdraw for a second, only to join again. Their sinuous forms wove together like twisting ropes of windblown smoke.

Eragon could never remember how long they fought. It was timeless, filled with nothing but action and reaction. Zar'roc grew leaden in his hand; his arm burned ferociously with each stroke. At last, as he lunged forward, Arya nimbly sidestepped, sweeping the point of her sword up to his jawbone with supernatural speed.

Eragon froze as the icy metal touched his skin. His muscles trembled from the exertion. Dimly he heard Saphira bugle and the warriors cheering raucously around them. Arya lowered her sword and sheathed it. "You have passed," she said quietly amid the noise.

Eragon outspars one of the best elven duelists in Du Weldenvarden:

This time it was Vanir who initiated the fight. In a single bound, he crossed the distance between them and thrust his blade toward Eragon's right shoulder. To Eragon, it seemed as if the elf moved slower than usual, as if Vanir's reflexes had been reduced to the level of a human's. It was easy for Eragon to deflect Vanir's sword, blue sparks flying from the metal as their blades grated against one another.

Vanir landed with an astonished expression. He struck again, and Eragon evaded the sword by leaning back, like a tree swaying in the wind. In quick succession, Vanir rained a score of heavy blows upon Eragon, each of which Eragon dodged or blocked, using Zar'roc's sheath as often as the sword to foil Vanir's onslaught.

Eragon soon realized that the spectral dragon from the Agaeti Blodhren had done more than alter his appearance; it had also granted him the elves' physical abilities. In strength and speed, Eragon now matched even the most athletic elf.

Fired by that knowledge and a desire to test his limits, Eragon jumped as high as he could. Zar'roc flashed crimson in the sunlight as he flew skyward, soaring more than ten feet above the ground before he flipped like an acrobat and came down behind Vanir, facing the direction from which he had started.

A fierce laugh erupted from Eragon. No more was he helpless before elves, Shades, and other creatures of magic. No more would he suffer the elves' contempt. No more would he have to rely on Saphira or Arya to rescue him from enemies like Durza.

He charged Vanir, and the field rang with a furious din as they strove against each other, raging back and forth upon the trampled grass. The force of their blows created gusts of wind that whipped their hair into tangled disarray. Overhead, the trees shook and dropped their needles. The duel lasted long into the morning, for even with Eragon's newfound skill, Vanir was still a formidable opponent. But in the end, Eragon would not be denied. Playing Zar'roc in a circle, he darted past Vanir's guard and struck him upon the upper arm, breaking the bone.

Vanir dropped his blade, his face turning white with shock.

Eragon defeats a group of Urgals:

Eragon tried to join him but was blocked by four of the monsters. The first one swung a sword at his shoulder. He ducked the blow and killed the Urgal with magic. He caught a second one in the throat with Zar'roc, wheeled wildly, and slashed a third through the heart.

Eragon knows how to fight with a staff, and uses one to fight off two Ra'zac:

Eragon spun the hawthorn staff in his hands and knocked aside the Ra'zac's sword when it was less than an inch from his ribs. The Ra'zac landed in front of him and jutted out its neck. Eragon recoiled as a short, thick beak appeared from within the depths of its hood. The chitinous appendage snapped shut just short of his right eye. In a rather detached way, Eragon noticed that the Ra'zac's tongue was barbed and purple and writhed like a headless snake.

Bringing his hands together at the center of the staff, Eragon drove his arms forward, striking the Ra'zac across its hollow chest and throwing the monster back several yards. It fell upon its hands and knees. Eragon pivoted around Roran, whose left side was slick with blood, and parried the sword of the other Ra'zac. He feinted, beat the Ra'zac's blade, and, when the Ra'zac stabbed at his throat, whirled the other half of the staff across his body and deflected the thrust. Without pausing, Eragon lunged forward and planted the wooden end of the staff in the Ra'zac's abdomen.

If Eragon had been wielding Zar'roc, he would have killed the Ra'zac then and there. As it was, something cracked inside the Ra'zac, and the creature went rolling across the cave for a dozen or more paces. It immediately popped up again, leaving a smear of blue gore on the uneven rock.

I need a sword, thought Eragon.

He widened his stance as the two Ra'zac converged upon him; he had no choice but to hold his ground and face their combined onslaught, for he was all that stood between those hook-clawed carrion crows and Roran. He began to mouth the same spell that had proved itself against the Lethrblaka, but the Ra'zac executed high and low slashes before he could utter a syllable.

The swords rebounded off he hawthorn with a dull bonk. They did not dent or otherwise mar the enchanted wood.

Left, right, up, down. Eragon did not think; he acted and reacted as he exchanged a flurry of blows with the Ra'zac. The staff was ideal for fighting multiple opponents, as he could strike and block with both ends, and often simultaneously. That ability served him well now. He panted, each breath short and quick. Sweat dripped from his brow and gathered at the corners of his eyes, and a layer greased his back and the undersides of his arms. The red haze of battle dimmed his vision and throbbed in response to the convolutions of his heart.

He never felt so alive, or afraid, as he did when fighting.

Eragon's own wards were scant. Since he had lavished the bulk of his attention on Saphira and Roran, Eragon's magical defenses soon failed, and the smaller Ra'zac wounded him on the outside of his left knee. The injury was not life-threatening, but it was still serious, for his left leg wound no longer support his full weight.

Gripping the spike at the bottom, Eragon swung the staff like a club and bashed one Ra'zac upside the head. The Ra'zac collapsed, but whether it was dead or only unconscious, Eragon could not tell. Advancing upon the remaining Ra'zac, he battered the creature's arms and shoulders and, with a sudden twist, knocked the sword out of its hand.

Eragon, whilst injured and somewhat exhausted, stomps one of the Ra'zac, who was in similar condition at the time (credit to @brightsteel):

As if this attempt were nothing more than a preliminary gesture that custom dictated they observe before proceeding with their actual confrontation, the Ra’zac stooped, placed the bow on the floor, then straightened its cowl and slowly and deliberately pulled its leaf-bladed sword from underneath its robes. While it did, Eragon rose to his feet and took a shoulder-wide stance, his hands tight on the staff.

They lunged toward each other. The Ra’zac attempted to cleave Eragon from collarbone to hip, but Eragon twisted and stepped past the blow. Jamming the end of the staff upward, he drove its metal spike underneath the Ra’zac’s beak and through the plates that protected the creature’s throat.

The Ra’zac shuddered once and then collapsed.

Before his re-training by Glaedr, Eragon states that he would have been able to defeat Wyrden, one of his Elven spellcaster bodyguards, if they were engaged in a real-life duel instead of a friendly spar:

His pleasure, however, vanished when Wyrden landed four touches in quick succession: one on Eragon’s right shoulder, two on his ribs, and a wicked draw cut across his abdomen. The blows smarted, but Eragon’s pride smarted even more. It worried him that the elf had been able to slip past his guard so easily. If they had been fighting in earnest, Eragon knew that he would have been able to defeat Wyrden in their first few exchanges, but that thought was of little comfort.

Glaedr teaches Eragon a new way of fighting, The Way of Knowing/The Way of the Warrior, which is a technique that focuses on reading body movement and language, fighting without emotional distractions, and gathering all the information you know about your opponent to help you defeat them. After just one session of being instructed in his manner of fighting, Eragon was able to match Arya in a sword fight, who had previously outfought him easily every day in their spars.

Here are exerts of Glaedr teaching Eragon:

All great fighting is the same, Eragon, even as all great warriors are the same. Past a certain point, it does not matter whether you wield a sword, a claw, a tooth, or a tail. It is true, you must be capable with your weapon, but anyone with the time and the inclination can acquire technical proficiency. To achieve greatness, though, that requires artistry. That requires imagination and thoughtfulness, and it is those qualities that the best warriors share, even if, on the surface, they appear completely different.

[...]

You have allowed yourself to become angrier than you should, said Glaedr softly. Anger has its place, but it will not help you here. The way of the warrior is the way of knowing. If that knowledge requires you to use anger, then you use anger, but you cannot wrest forth knowledge by losing your temper. Pain and frustration will be your only reward if you try.

Instead, you must strive to be calm, even if a hundred ravening enemies are napping at your heels. Empty your mind and allow it to become like a tranquil pool that reflects everything around it and yet remains untouched by its surroundings. Understanding will come to you in that emptiness, when you are free of irrational fears about victory and defeat, life and death.

You cannot predict every eventuality, and you cannot guarantee success every time you face an enemy, but by seeing all and discounting nothing, you may adapt without hesitation to any change. The warrior who can adapt the easiest to the unexpected is the warrior who will live the longest.

So look at Arya, see what you are looking at, and then take the action you deem most appropriate. And once you are in motion, do not allow your thoughts to distract you. Think without thinking, so that you act as if out of instinct and not reason.

[...]

Do not try to move quickly, Eragon. Do not try to move slowly. Only move at the correct moment and your blow will appear neither fast nor slow but effortless. Timing is everything in battle. You must pay close attention to the patterns and rhythms of your opponents' bodies: where they are strong, where they are weak, where stiff and where flexible. Match those rhythms when it serves your purpose and confuse them when ir does not, and you will be able to shape the flow of the battle as it pleases you. This you should understand thoroughly.

[...]

Keep hold of the things you need to remember, but don't let them distract you from what is happening. Find a place of calm within yourself, and let the concerns of the world wash over you without sweeping you away with them. You should feel as you did when Oromis had you listen to the thoughts of the creatures in the forest. Then you were aware of everything that was going on around you, yet you were not fixated on any one detail.

After fighting for a long time and receiving numerous minor wounds that were heeding his ability to fight, Eragon finally defeated Murtagh in a duel:

As they started toward each other once again, Eragon sidled to Murtahg's right, while at the same time allowing his sword arm to drift away from the side of his body, as if through exhaustion or carelessness. It was a slight motion, but he knew that Murtagh would notice and that he would attempt to exploit the opening he had provided.

At that moment, Eragon felt nothing. He still registered the pain from his wounds, but at a remove, as if the sensations were not his own. His mind was like a pool of deep water on a breathless day, flat and motionless, and yet filled with the reflection of those things around it. What he saw, he registered without conscious thought. The need for that had passed. He understood all that was before him, and further contemplation would only hamper him.

As Eragon expected, Murtagh lunged toward him, stabbing at the middle of his belly.

When the time was ripe, Eragon turned. He moved neither fast nor slow but at just the right speed the situation required. The motion felt preordained, as if it were the only action he could have taken.

Instead of striking him in the gut, as Murtagh had intended, Zar'roc struck Eragon in the muscles along his right side, directly below his ribcage. The impact felt like a hammerblow, and there was a steely slither as Zar'roc slid past the broken links of his mail and into his flesh. The coldness of the metal made Eragon gasp more than the pain itself.

Behind him, the tip of the blade tugged at his hauberk as it emerged from his body.

Murtagh stared, seemingly taken aback.

Before Murtagh could recover, Eragon drew back his arm and thrust Brisingr into Murtagh's abdomen, close to his naval: a far worse wound than the one Eragon had just received.

Senses

After the Blood-oath Celebration, Eragon has elf-like senses:

Eragon floated in a state of heightened awareness, his senses thrumming with the multitude of new sights, sounds, smells, and feelings that assailed him. He could see in darkness that would have blinded him before. He could touch a leaf and, by touch alone, count the individual hairs that grew upon it. He could identify the odors wafting about him as well as a wolf or a dragon. And he could hear the patter of mice in the underbrush and the noise a flake of bark makes as it falls to earth; the beating of his heart was as a drum to him.

In his spar with Vanir, the two of them move their swords fast enough to create gusts of wind that whipped their hair aside and shook the needles from trees:

He charged Vanir, and the field rang with a furious din as they strove against each other, raging back and forth upon the trampled grass. The force of their blows created gusts of wind that whipped their hair into tangled disarray. Overhead, the trees shook and dropped their needles.

Eragon catches an arrow out of the air, faster than any human:

He missed one arrow, though, which was fired a few seconds after the first volley.

Eragon leaned as far to his right as he could and, faster than any normal human, plucked the arrow from the air as Saphira flew past it.

Eragon deflects an arrow from close range with a wooden staff (credit to @brightsteel) :

A mare’s tail of blood separated Eragon from his enemy as the Ra’zac swept back its sodden cloak, revealing a bow that it held with an arrow already fit to the string. Lifting and drawing the weapon, the Ra’zac loosed the bolt in the direction of Eragon’s chest. Eragon batted the shaft aside with his staff.

Eragon crosses a hundred feet in a few seconds:

Eragon waited until the two closest sentinels had their backs turned toward him, and then he sprinted with all his might. Within seconds, he traversed the hundred or so feet that separated the rain barrel from the slope of the rampart and dashed up the embankment so fast, he felt as if he were a stone skipping across water.

Eragon dodges attacks from a dwarf, which move faster than the eye could see:

Then the last of the black-garbed dwarves was upon him. Eragon parried his dagger twice . . . thrice . . . and then cut through the dwarf’s padded sleeve and scored his dagger arm from the elbow to the wrist. The dwarf hissed with pain, blue eyes furious above his cloth mask. He initiated a series of blows, the dagger whistling through the air faster than the eye could follow, which forced Eragon to hop away to avoid the deadly edge. The dwarf pressed the attack. For several yards, Eragon succeeded in evading him, until his heel struck a body and, in attempting to step around it, he stumbled and fell against a wall, bruising his shoulder.

Eragon swings his sword faster than human and elf eyes can see:

Eragon and Arya have a duel in a matter of seconds, in which all of the underlined parts happened:

The duel lasted only a few seconds, though it was still long enough for them to exchange a flurry of blows. Shields cracked, chunks of torn sod flew over the ground, and sword rang against sword as they flowed from one stance to another, their bodies twisting through the air like twin columns of smoke.

In the end, the result was the same as before. Eragon slipped past Arya's guard with an adroit bit of footwork and a flick of his wrist, which resulted in him slashing Arya across her chest, from shoulder to sternum.

Christopher Paolini claims that Eragon can stab twenty times a second with Brisingr, his Rider sword, and strike more than twenty times a second with a regular weapon like a rapier:

Strength/Physicals

After the Blood-oath Celebration, Eragon is now as fit as the most athletic elf. As a reminder, even the weakest elf is many times faster and stronger than the strongest (peakest) human:

Eragon soon realized that the spectral dragon from the Agaeti Blodhren had done more than alter his appearance; it had also granted him the elves' physical abilities. In strength and speed, Eragon now matched even the most athletic elf.

Eragon draws his sword but sends it flying and embeds it in a tree trunk to the point that even another elf had trouble getting it out:

Emptying his mind, Eragon grasped and drew Zar'roc as fast as he could. To his surprise, the sword felt as if it weighed no more than a willow wand. Without the expected resistance, Eragon's arm snapped straight, tearing the sword from his hand and sending it whirling twenty yards to his right, where it buried itself in the trunk of a pine tree.

[...]

"See that it does not happen again." Going to the tree, Vanir gripped Zar'roc's hilt and tried to pull the sword free. The weapon remained motionless. Vanir's eyebrows met as he frowned at the unyielding crimson blade, as if he suspected some form of trickery. Bracing himself, the elf heaved backward and, with the crack of wood, yanked Zar'roc out of the pine.

Eragon jumps ten feet in the air:

Fired by that knowledge and a desire to test his limits, Eragon jumped as high as he could. Zar'roc flashed crimson in the sunlight as he flew skyward, soaring more than ten feet above the ground before he flipped like an acrobat and came down behind Vanir, facing the direction from which he had started.

Eragon's new strength allows him to cleave helms in two, splinter shields, dent armor, and cut opposing swords in half:

Once there, Eragon could not tell from whose mouth emanated the ravenous jet of flame that consumed a dozen soldiers, cooking them in their mail, nor whose arm it was that brought Zar'roc down in an arc, cleaving a soldier's helm in half.

Eragon incapacitates a man with a punch to his armpit, snaps two soldiers' spines, then punches another man in the chest, caving in his armor and sending him flying a dozen feet away:

Four soldiers who had dismounted confronted him with drawn swords. They charged. Dodging to the right, he caught the first soldier's wrist as the man swung his sword and punched him in the armpit. The man collapsed and was still. Eragon dispatched his next opponents by twisting their heads until their spines snapped. The fourth soldier was so close by then, running at him with sword held high, Eragon could not evade him.

Trapped, he did the one thing he could: he struck the man in the chest with all his might. A fount of blood and sweat erupted as his fist connected. The blow staved in the man's ribs and propelled him more than a dozen feet over the grass, where he fetched up against another corpse.

Eragon punches through a dwarves' shield with relative ease and sends the dwarf behind the shield into the opposite wall, killing him:

Releasing the buckler with his right hand but still holding on with his left, Eragon drew back his arm and struck the shield as hard as he could, punching through the tempered steel as easily as if it were made of rotten wood. Because of the calluses on his knuckles, he felt no pain from the impact.

The force of the blow threw the dwarf against the opposite wall. His head lolling upon a boneless neck, the dwarf dropped to the ground, like a puppet whose strings had been severed.

Eragon stabs through a soldier's shield, then his arm, and out through his body:

Eragon waited until the captain was only a few feet away. Then he took a single step forward and stabbed Brisingr through the center of the man's embossed shield, through his arm underneath, and then through the man's chest and out his back. The man convulsed once and was still.

Eragon breaks his falchion against a wall, even though he had previously put spells on it to prevent such things:

The nearest of the last two attackers raised his shield in anticipation of the blow Eragon was about to direct at him. Summoning the full measure of his might, Eragon cut at the shield, intending to shear it and the arm underneath in half, as he had often done with Zar’roc. In the fever of battle, though, he forgot to account for the dwarf’s inexplicable speed. As the falchion neared its target, the dwarf tilted his shield, so as to deflect the blow to the side. Two plumes of sparks erupted from the surface of the shield as the falchion glanced off the upper part and then the steel spike mounted in the center.

Momentum carried the falchion farther than Eragon had intended, and it continued flying through the air until it struck edge-first against a wall, jarring Eragon’s arm. With a crystalline sound, the blade of the falchion shattered into a dozen pieces, leaving him with a six-inch spike of jagged metal protruding from the hilt

[...]

Eragon walked to where the remains of his falchion lay. He knelt in the soot and, with the tip of a finger, touched one of the pieces of metal, tracing its ragged edges. I must have hit the shield and the wall so hard, I overwhelmed the spells I used to reinforce the steel, he thought.

Eragon hits one of the Ra'zac, throwing them back several yards:

Bringing his hands together at the center of the staff, Eragon drove his arms forward, striking the Ra’zac across its hollow chest and throwing the monster back several yards. It fell upon its hands and knees. Eragon pivoted around Roran, whose left side was slick with blood, and parried the sword of the other Ra’zac. He feinted, beat the Ra’zac’s blade, and, when the Ra’zac stabbed at his throat, whirled the other half of the staff across his body and deflected the thrust. Without pausing, Eragon lunged forward and planted the wooden end of the staff in the Ra’zac’s abdomen.

Eragon hits one of the Ra'zac in the chest, breaking something in their chest, and then sending them rolling backwards form a dozen or more paces:

If Eragon had been wielding Zar’roc, he would have killed the Ra’zac then and there. As it was, something cracked inside the Ra’zac, and the creature went rolling across the cave for a dozen or more paces. It immediately popped up again, leaving a smear of blue gore on the uneven rock.

Eragon slices off a dozen spearheads and cuts through chainmail with ease, then bashes a man with his shield into three other men, sending them sprawling:

Eragon ran forward and, with a single stroke of Brisingr, lopped off the tops of a dozen polearms as easily as he had flicked off the seed heads of barley stalks when he was younger. He slashed the nearest soldier across the chest, slicing through his mail as if it were the flimsiest of cloth. A fountain of blood arose. Then Eragon stabbed the next soldier in line and struck the soldier to his left with his shield, knocking the man into three of his companions and bowling them over.

Eragon rams his shoulder into an enemy soldier, sending him back a few feet and clutching his chest:

A spear thudded against Eragon's shield, bruising his shoulder. He whirled toward the thrower, a big, scarred man missing his lower front teeth, and sprinted at him. The man struggled to draw a dagger from his belt. At the last moment, Eragon twisted, tensed his arms and chest, and rammed his sore shoulder into the man's sternum.

The force of the impact drove the soldier backward several yards, whereupon he collapsed, clutching at his heart.

Eragon kills a soldier with a punch:

He sped around a corner and collided with a soldier walking in the opposite direction. Eragon's vision flashed red and yellow as his forehead struck the rim of the man's shield. He clung to the soldier, and the two of them staggered back and forth across the corridor like a pair of drunk dancers.

The soldier uttered an oath as he struggled to regain his balance. "What's wrong with you, you thrice-blasted----" he said, and then he saw Eragon's face, and his eyes widened. "You!"

Eragon balled his right and and punched the man in the belly, directly underneath his rib cage. The blow lifted the man off his feet and smashed him into the ceiling. "Me," Eragon agreed as the man dropped to the floor, lifeless.

Eragon dispatches more soldiers with punches, sending them flying as well:

With his left hand, Eragon swung at the woman. For whatever reason, the spell did not stop his fist, and he felt the bones in her chest give way as he knocked her sprawling into the people behind her.

The remaining priests extricated themselves and resumed their charge. Stepping forward, Eragon blocked a clumsy slash from the foremost priest; then----with a shout of "Ha!"----he drove his fist into the man's gut and sent him flying into a pew, which the priest struck with a nasty crack.

Gear

Brisingr

Brisingr, Eragon's new Rider sword, which will never dent, rust, or break. The sword also catches on fire every time Eragon utters its name out loud:

Covering the blade was a glossy scabbard of the same dark blue as the scales on Saphira's back. The color displayed a slight variegation, like the mottled light at the bottom of a clear forest pond. A piece of blued brightsteel carved in the shape of a leaf capped the end of the scabbard while a collar decorated with stylized vines encircled the mouth. The curved crossguard was also made of blued brightsteel, as were the four ribs that held in place the large sapphire that formed the pommel. The hand-and-a-half hilt was made of hard black wood.

[...]

Like the rest of the sword, the blade was blue, but of a slightly lighter shade; it was the blue of the scales in the hollow of Saphira's throat rather than the blue of those on her back. And as it was on Zar'roc, the color was iridescent; as Eragon moved the sword about, the color would shimmer and shift, displaying any of the many tones of blue present on Saphira herself. Through the wash of color, the cable-like patterns within the brightsteel and the pale bands along the edges were still visible.

With a single hand, Eragon swung the sword through the air, and he laughed at how light and fast it felt. The sword almost seemed alive. He grasped the sword with both his hands then and was delighted to find that they fit perfectly on the longer hilt.

[...]

Eragon consulted with Saphira, and when she agreed with his choice, he lifted the weapon to shoulder level and said, "I am decided. Sword, I name thee Brisingr!"

And with a sound like a rushing wind, the blade burst into fire, an envelope of sapphire-blue flames writhing about the razor-sharp steel.

Source: Brisingr

Brisingr has spells of countermagic built into it to allow the weapon to slice through magical enchantments:

Grasping his sword with both hands, Eragon lifted it overhead and shouted, "Brisingr!" The blade burst into blue fire, and the warriors behind him uttered exclamations of amazement. Eragon stepped forward then and smote one of the crossbars of the portcullis. A blinding flash lit the wall and surrounding buildings as the sword sliced through the thick piece of metal. At the same time, Eragon noticed a sudden increase in his fatigue as Brisingr severed the wards protecting the portcullis. He smiled. As he had hoped, the spells of countermagic with which Rhunon had imbued Brisingr were more than sufficient to defeat the enchantments.

Source: Brisingr

Eragon can also strengthen the fire and temperature of his sword at will, making it hot enough to cut through thick wood like a knife through fresh bread:

He aligned Brisingr with the hairline crack between the two doors, put his weight behind the sword, and pushed the blade through the narrow gap and out the other side. Then he increased the flow of energy to the fire blazing around the blade until it was hot enough to burn its way through the dense wood as easily as a knife cuts through fresh bread.

Eldunari

Eldunari description:

Eragon is given Glaedr's Eldunari before him and Oromis depart to fight the Empire:

I have decided, said Glaedr, to give you my heart of hearts, Saphira Brightsclaes, Eragon Shadeslayer.

Saphira's astonishment was no less than Eragon's. Together, they stared at the majestic gold dragon who towered high above them. Saphira said, Master, you honor us beyond words, but . . . are you sure that you wish to entrust your heart to us?

I am sure, said Glaedr, and lowered his massive head until it was only slightly above Eragon. For many reasons, I am sure. If you hold my heart, you shall be able to communicate with Oromis and me----no matter how far apart we may be----and I shall be able to aid you with my strength whenever you are in difficulty. And if Oromis and I should fall in battle, our knowledge and experience, and also my strength, shall still be at your disposal. Long have I pondered this choice, and I am confident it is the right one.

[...]

Then Glaedr drew back his head. The muscles of his abdomen rippled and clenched several times, and his throat began to convulse, as if something were stuck in it. Widening his stance, the gold dragon extended his neck straight out in front of him, every cord and sinew of his body standing in high relief underneath the armor of his sparkling scales. Glaedr's throat continued to flex and relax with increasing speed until at last he lowered his head so that it was level with Eragon and opened his jaws, hot, pungent air pouring from his massive maw. Eragon squinted and tried not to gag. As he gazed into the depths of Glaedr's mouth, Eragon saw the dragon's throat contract one last time, and then a hint of gold light appeared between the folds of dripping, blood-red tissue. A second later, a round object about a foot in diameter slid down Glaedr's crimson tongue and out of his mouth so fast, Eragon nearly missed catching it.

As his hands closed around the slippery, saliva-covered Eldunari, Eragon gasped and staggered backward, for he suddenly felt Glaedr's every thought and emotion, and all of the sensations of his body. The amount of information was overwhelming, as was the closeness of their contact. Eragon had expected as much, but it still shocked him to realize he was holding Glaedr's entire being between his hands.

[...]

The Eldunari itself was like a giant jewel. Its surface was warm and covered with hundreds of sharp facets, which varied somewhat in size and sometimes projected at odd, slanting angles. The center of the Eldunari glowed with a dull radiance, similar to that of a shattered lantern, and the diffuse light throbbed with a slow, steady beat. Upon first inspection, the light appeared uniform, but the longer Eragon gazed at it, the more details he saw within it: small eddies and currents that coiled and twisted in seemingly random directions, darker motes that barely moved at all, and flurries of bright flashes no larger than the head of a pin that would flare for a moment, then fade back into the underlying field of light. It was alive.

Source: Brisingr

Eragon is also in possession of Umaroth's Eldunari. Umaroth's strength is great enough to overwhelm the minds of Eragon, Saphira, and Glaedr easily, something even the strongest spellcasters in the land would be hard pressed to do, if they could at all:

Then Cuaroc swung shut his breastplate, and Umaroth said, No, I am over here, and he directed Eragon's vision toward an alcove that contained a large white Eldunari.

Source: Inheritance

Eragon brings with him 131 Eldunari (not including Glaedr) to fight against Galbatorix, and after he defeats him, he is in possession of all 136 that were in the Vault of Souls on Vreongard:

Satisfaction came from Umaroth, and he replied, Now that you have found us, our days of hiding are over; we would go with you to Uru'baen and fight alongside you to kill Galbatorix. The time has come for us to leave our den and once and for all confront that traitorous eggbreaker. Without us, he would be able to pry open your minds as easily as did we, for he has many Eldunari at his command.

I cannot carry all of you, said Saphira.

You shall not have to, said Umaroth. Five of us will stay to watch over the eggs, along with Cuaroc. In the event we should fail to defeat Galbatorix, they will tamper no more with the skeins of energy, but will content themselves with waiting until it is again safe for dragons to venture forth in Alagaesia. But you need not worry; we shall not be a burden to you, for we will provide the strength to move our weight.

"How many of you are there?" asked Eragon, gazing around the room.

One hundred and thirty-six.

Belt of Beloth the Wise

The belt of Beloth the Wise, given to him by Oromis:

He handed the bottle to Eragon, then removed a long black-and-blue sword belt from the pouch. The belt felt unusually thick and heavy to Eragon when he ran it through his hands. It was made of cloth threads woven together in an interlocking pattern that depicted a coiling Liani Vine. At Oromis's instruction, Eragon pulled at a tassel at the end of the belt and gasped as a strip in its center slid back to expose twelve diamonds, each an inch across. Four diamonds were white, four were black, and the remainder were red, blue, yellow, and brown. They glittered cold and brilliant, like ice in the dawn, casting a rainbow of multicolored specks onto Eragon's hands.

"Master . . ." Eragon shook his head, at a loss for words for several breaths. "Is it safe to give this to me?"

"Guard it well so that none are tempted to steal it. This is the belt of Beloth the Wise----who you read of in your history of the Year of Darkness----and is one of the great treasures of the Riders. These are the most perfect gems the Riders could find. Some we traded for with the dwarves. Others we won in battle or mined ourselves. The stones have no magic of their own, but you may use them as repositories for your own power and draw upon that reserve when in need. This, in addition to the ruby set in Zar'roc's pommel, will allow you to amass a store of energy so that you do not become unduly exhausted casting spells in battle, or even when confronting enemy magicians.

Yew Bow

Yew bow, given to him by the queen of the elves, Queen Islanzandi:

Islanzadi extended a hand and one of the elf lords handed her a shallow, unadorned wooden box. "Oromis had his gifts for you, and I have mine. Let them remind you of your time spent with us under the dusky pines." She opened the box, revealing a long, dark bow with reflexed limbs and curled tips nestled on a bed of velvet. Silver fittings chased with dogwood leaves decorated the ears and grip of the bow. Beside it lay a quiver of new arrows fletched with white swan feathers. "Now that you share our strength, it seems only proper that you should have one of our bows. I sang it myself from a yew tree. The string will never break. And so long as you use these arrows, you will be hard-pressed to miss your target, even if the wind should gust during your shot."

Armor

Eragon's armor at the battle of Farthen Dur, which he later would keep:

Over Eragon's head went a stiff shirt of leather-backed mail that clinked when he moved. He belted Zar'roc over it, which helped keep the mail from swinging. On his head went a leather cap, then a mail coif, and finally a gold-and-silver helm. Bracers were strapped to his forearms, and greaves to his lower legs. For his hands there were mail-backed gloves. Last, Orik handed him a broad shield emblazoned with an oak tree.

Aren

Aren, Brom's ring given to Eragon, which has enough energy stored in it to take apart an entire castle:

It took Eragon a moment to remember that Aren was the name of Brom's ring; he had heard it uttered only once before, from Islanzadi, on the day he arrived in Ellesmera. My ring now, he told himself. I have to stop thinking of it as Brom's. He cast a critical gaze at the large sapphire that sparkled in its gold setting on his finger. "I don't know if there is any energy in Aren. I've never stored any there myself, and I never checked it Brom had." Even as he spoke, he extended his consciousness toward the sapphire. The instant his mind came into contact with the gem, he felt the presence of a vast, swirling pool of energy. To his inner eye, the sapphire thrummed with power. He wondered that it did not explode from the amount of force contained within the boundaries of its sharp-edged facets. After he used the energy to wash away his aches and pains and restore strength to his limbs, the treasure trove inside Aren was hardly diminished.

His skin tingling, Eragon severed his link with the gem. Delighted by his discovery and his sudden sense of well-being, he laughed out loud, then told Arya what he had found. "Brom must have squirreled away every bit of energy he could spare the whole time he was hiding in Carvahall." He laughed again, marveling. "All those years . . . With what's in Aren, I could tear apart an entire castle with a single spell."

Saddle:

He stepped into his hut for a moment and reappeared carrying a thick, molded saddle decorated with gilt designs along the seat and leg pieces. "----use this. It was crafted in Vroengard and imbued with many spells so that it will never fail you in time of need."

Eragon staggered under the weight of the saddle as he received it from Oromis. It had the same general shape as Brom's, with a row of buckles----intended to immobilize his legs----hanging from each side. The deep seat was sculpted out of leather in such a way that he could fly for hours with ease, both sitting upright and lying flat against Saphira's neck. Also, the straps encircling Saphira's chest were rigged with slips and knots so that they could extend to accommodate years of growth. A series of broad ties on either side of the head of the saddle caught Eragon's attention. He asked their purpose.

Glaedr rumbled, Those secure your wrists and arms so that you are not killed like a rat shaken to death when Saphira performs a complex maneuver.

Info about Dragon Riders

"Before your grandfathers' fathers were born, and yea, even before their fathers, the Dragon Riders were formed. To protect and guard was their mission, and for thousands of years they succeeded. Their prowess in battle was unmatched, for each had the strength of ten men. They were immortal unless blade or poison took them. For good only were their powers used, and under their tutelage tall cities and towers were built out of the living stone. While they kept peace, the land flourished."

Source: Eragon

"You forget that dragons were magical----they affected everything around them in strange ways. The Riders were closest to them and experienced this the most. The most common side effect was an extended life. Our king has lived long enough to make that apparent, but most people attribute it to his own magical abilities. There were also other, less noticeable changes. All the Riders were stronger of body, keener of mind, and truer of sight than normal men."

Source: Eragon

"Young Riders like yourself were put through a strict regimen designed to strengthen their bodies and increase their mental control. This regimen continued for many months, occasionally years, until the Riders were deemed responsible enough to handle magic."

Source: Eldest

The Dragon Riders were created thousands of years earlier in the aftermath of the elves' great war with the dragons, in order to ensure that hostilities would never again afflict their two races. The Riders became peacekeepers, educators, healers, natural philosophers, and the greatest of spellweavers----since being joined with a dragon makes one a magician. Under their guidance and protection, the land enjoyed a golden age.

Thanks for reading. Click here to view my other Respect Threads.

Still unfinished, only half way done. But enjoy!

Awesome stuff so far, keep up the good work ^_^

@claymore1998: Thank you! ^.^

Impressive

Cool stuff in there. I started reading the Inheritance cycle right after i finished the Harry Potter books.

@primez0ne: Thanks Prime!

@thelegionproject: Thanks man! Have you finished the series?

Finished it last year :)

@thevivas: Yeah about 4 years ago in 2011.

@thevivas: No worries friend, you are most welcome ^_^

Updated with feats and the likes from Brisingr.

I'm wondering what levels of hax can Eragon achieve with so many Eldunaris in his possesion.

@i_am_lightning: He also knows the true name of the ancient language, so there's also that. Lol

Nice thread though I would like to point out his feat of punching through the dwarven shield he doesn't knock him unconscious. The dwarf has his neck broken when he hit the wall.

@eisenfauste: ......That's even better then. Lol. I'll change that soon, thanks for that!

@thevivas: No problem :)

Yaaaaaaaaaaaaaaaaaaay! Eragon respect thread!

Nice job!

Though, you missed this one for strength:

The nearest of the last two attackers raised his shield in anticipation of the blow Eragon was about to direct at him. Summoning the full measure of his might, Eragon cut at the shield, intending to shear it and the arm underneath in half, as he had often done with Zar’roc. In the fever of battle, though, he forgot to account for the dwarf’s inexplicable speed. As the falchion neared its target, the dwarf tilted his shield, so as to deflect the blow to the side. Two plumes of sparks erupted from the surface of the shield as the falchion glanced off the upper part and then the steel spike mounted in the center.

Momentum carried the falchion farther than Eragon had intended, and it continued flying through the air until it struck edge-first against a wall, jarring Eragon’s arm. With a crystalline sound, the blade of the falchion shattered into a dozen pieces, leaving him with a six-inch spike of jagged metal protruding from the hilt

......

Eragon walked to where the remains of his falchion lay. He knelt in the soot and, with the tip of a finger, touched one of the pieces of metal, tracing its ragged edges. I must have hit the shield and the wall so hard, I overwhelmed the spells I used to reinforce the steel, he thought.

Pretty impressive considering the fact that he's fully capable of trading blows with Murtagh with this sword. May of had something to do with what he hit however......

Then the last of the black-garbed dwarves was upon him. Eragon parried his dagger twice . . . thrice . . . and then cut through the dwarf’s padded sleeve and scored his dagger arm from the elbow to the wrist. The dwarf hissed with pain, blue eyes furious above his cloth mask. He initiated a series of blows, the dagger whistling through the air faster than the eye could follow, which forced Eragon to hop away to avoid the deadly edge. The dwarf pressed the attack. For several yards, Eragon succeeded in evading him, until his heel struck a body and, in attempting to step around it, he stumbled and fell against a wall, bruising his shoulder.

Another faster than the eye feat for Eragon, being able to keep up with the Dwarf.

@brightsteel: Thanks! And I like your username haha.

For some reason when I saw the feat of him shattering his falchion, I decided not to put it in there, but after thinking about it, I can't remember why I didn't want to put it in there.... Lol

And thanks for the dwarf feat, I must've missed that one!

Bump

Realized I didn't actually say it when I first posted on here, but good job on the thread. I was originally going to make an Eragon respect thread, but this saved me the trouble. Thanks. XD

Also, a somewhat on topic question. Why exactly is Eragon one of your favorite characters?

@darkdefender: You read the Inheritance books, DD?

Awesome job on the thread m8

Cool

Bump. Added some stuff to try to make it look better and be easier to read/more descriptive.

Bump just cause.
