Equipment
DAV for short is the physical yet mechanical body that Cater's soul resides in, his true name was lost with other details of his past life. Regardless the DAV was specifically designed by him when he still had his original body and its purpose was to be an improvement over the biological one.
DAV is constructed from Dwarven metals which are and so far have always been the best quality metal available on Mewni, its closest equivalent from Earth which is Titanium is several leagues weaker than it on a ounce per ounce basis. DAV not only boasts impressive physical durability due to the material it is constructed of but also the six potent enchantments that Caster has active at all times on them.
The first enchantment DAV possesses is the 'Tower' enchantment, this extremely rare enchantment serves as a reactive armor towards all energy based attacks launched towards Caster. Instead of harming him the energy is stored inside DAV and serves as a power source to fill his Martial Spirit or Magical spells, the 'Tower' enchantment is very powerful as even solar flares from stars have failed to over load what seems to be a capacitor with infinite capacity but 'Tower' only works against energy based attacks and fails against energy constructs or physical projectiles/strikes.
The second enchantment DAV possesses is a high resistance to Anti-Magic nullification attributes as well as Magic Absorption, this enchantment is called 'Containment' it serves almost as an insulation for Caster and prevents his magic from being forcefully removed or manipulated by outside parties.
The third enchantment DAV possess is 'Dwarven Perseverance' this enchantment allows Caster's mechanical form to self repair mid combat at a rate of 1/10th of his body per ten seconds so it would only take a minute for Caster to return to optimum physical efficiency.
The fourth enchantment DAV possesses is 'Temp' this enchantment makes DAV immune to all Heat and Cold based effect, the fifith enchantment DAV possesses is 'Anchor' this prevents Caster from being teleported or phased against his will and only allows so if he consents to this or the figure in question is a high tier reality warper
The final enchantment DAV possesses is 'Immorta' this places the Mewni soul in a state of immortality and prevents outside figures from manipulating his automic form as well as forms of Death Inducement/Life Manipulation
The Anchron Crystal is the only other piece of equipment Caster carries for as a Master Mage he needs no other equipment, the Anchron Crystal serves three purposes. The first grants Caster a self recharging supply of magical energy to power his spells and replenish is Martial Spirit, the second purpose serves as a way to permanently imprison Skyfather's and use their own power to serve Caster. The final and third person of the Anchron Crystal is to grant temporary aura's of absolute invulnerability towards an Anchron.
Magic Abilities
While other members of the Companions have an arsenal of weapons or equipment the old wizard does not and instead uses an arsenal of magical spells for fighting and aiding his allies.
Caster primarily uses three forms of restoration
[Remove Ailment]<- This spell removes various status effects such as poisons/toxins/viruses/debuffs/curses even exotic and unique ones from himself or his allies.
[Heal]<- This spell is used to heal all types of whether they be from burns/cuts/bruises/magic/cosmic//physical/severe or minor
[Resurrect]<- This spell is used to resurrect any fallen allies, even from Death Inducement/Reality Warping/Time Manipulation (Note it can not resurrect targets with out souls or those who have had their souls destroyed, it also can not resurrect Anchrons or those that died through natural causes)
Caster primarily uses seven forms of Destruction spells
[Fire]<- An incendiary spell capable of limited fire manipulation, hot enough to vaporize entire rivers instantaneously but powerful enough to destroy castles in single shots.
[Curse]<- A spell that halves an enemies physical attributes and quality of equipment/armor/weapon, making them half as Strong/Durable/Fast (Capable of being stacked up to three times)
[Storm]<- A spell that grants limited electrokinesis, enough lightning to lay waste to entire cities quickly but each individual bolt being a thousand times more powerful than a regular bolt.
[Whirl]<- A spell that grants limited aerokinesis, capable of manipulating the air to blow away entire mountains or asphyixate entire legions of soldiers.
[Earth]<- A spell that grants limited geokinesis, capable of commanding the masses of mountains or summoning massive Earth quakes to annihilate armies
[Absorption]<- A ranged based ray spell that absorbs an enemies life force and mana based on the duration the ray remains on the target, the longer it remains the more life force and mana is absorbed per second.
[Silence]<- A spell that prevents enemy mages from using magic (Effects targets below planetary scale)
Caster primarily uses three forms of Conjuration
[Ethereal Swords]<- Intangible swords are summoned that are capable of causing harm whilst still remaining intangible. These Ethereal Swords are powerful enough to easily cleave through those more durable than a mountain yet only special attributes or techniques are able to make Ethereal swords tangible and thus vulnerable to harm.
[Elemental Golems]<- Physical humanoid creatures made out of three possible elements Earth/Water/Fire/ are summoned to do Caster's bidding and are only banished if their elemental energy is absorbed or physical forms are banished.
[Sustenance]<- A spell capable of summoning various types of food and liquids to feed/quench allies.
Caster primarily uses six forms of Alteration
[Multiward]<- Caster's most used spell due to its defensive purposes, provides an invisible barrier that protects users from all manners of attacks so long as its active at the cost of requiring mana to recast the shield every time he breaks. These force fields provide the selected targets with the durability of a massive mountain yet their mobility and strength remained unaffected.
[Medusa's Stare]<- A spell that transmutates targets into Stone
[Enlighten]<- A spell that reduces the weight of the target by 1/100th of its original weight (Ergo something weighing 100 tons is now only 1 ton) Caster can stack this spell up to ten times before it reaches its limits, typically the duration of the spell once stack ten times can last up to a day while being only used once can last up to an hour
[Gills]<- A spell that grants the selected targets the ability to breathe water for a day
[Light]<- A spell that creates a source of luminosity, the more mana used the greater the brightness
[Burden]<- A spell that is the opposite of Enlight, instead of making the target 1/100th of its weight the spell Burden makes the target 100x times its original weight and can be stacked up to ten times with the same duration Enlighten has.
Caster primarily uses three forms of Illusion
[Invisibility]<- A spell that makes the selected targets immune to detection, the only methods of detection is through having a very powerful form of supernatural detection (Regular supernatural detection is not sufficient) for even through searching all fields of the visible spectrum and searching carefully for sounds will result in failed attempts to detect figures with Caster's Invisibility spell.
[Nightmare]<- A spell that is a form of high level telepathy, the enemies greatest fears are brought to life in a powerful illusion or resurface into their memory in a extended loop (The more mana placed the longer Nightmare lasts)
[Decoy]<- A spell that creates hardlight copies of a selected target
MS Abilities
Caster possesses only two MS abilities
A very powerful mental attack that is the equivalent of an Omega level telepath unleashing his or her full power onto an opponent but rather than breaking or dominating a mind the MS technique does neither and rather confuses the minds commands. Once MS Mayhem is used all the actions that a foe does now become the opposite (If an opponent tries to flee they will fight and vice versa, if an opponent decides to take a step forward their body will instead they a step backward, if an opponent wants to evade an attack they will instead attempt to withstand an attack, if an opponent which to aid an ally they will instead inconvenience the ally by either attacking or refusing to give support, etcetera)
For a short duration MS Alpha Strike gives Caster no warm up times or cool downs for his spells as well as giving him limitless mana, MS Alpha Strike thus gives the Caster the ability to spam all his magical abilities simultaneously with out any strain or concern for managing his magical reserves so long as his Martial Spirit reserves do not fail.
Physicals
25 ton lifting and striking strength but this is his maximum limit
Massively Hypersonic, twice as fast as lightning in both combat and reaction speed but due to having no biological body he has limitless stamina to keep up this pace indefinitely
Blunt trauma durability is makes Caster a man sized fortress but he is still relatively weak compared to most Companions yet his resistance to penetrating attacks are far greater than his resistance to blunt trauma attacks (Because the impacts still travel in and damage fine cogs and gears while the blades are stopped by his armor)
Miscellaneous
Caster has all the mannerisms of a polite elderly man, his patience and wisdom is greater than all the other members of the Companions combined and none could say that they have ever seen him truly furious. Caster is the type of person to let bygones be bygones and give others second chances and surprisingly despite being only 5'0 in height his body is incredibly dense due to the way he smithed the Dwarven Metal which makes him weigh 1,000 lbs when not using magic.
He has an almost grand father like effect over the companions and is always there to help both emotionally and physically.
