Basically as others have stated, it is really, really hard to do so. A blade forged from an abstract level being using stars was capable of killing a darkness entity, but that wasn't Jackie it killed. The Witchblade, which is the child of two abstracts has done it, but we don't know the exact circumstances yet, so it is really hard to say.

I need to find the writeup, but there is a little breakdown in one of the books, where it attributes the blade as granting superhuman stats to wielders and so on, but I forget what else it stated about it. I need to dig through my books and find it.

@dondave: Probably from the idea that it has hurt/killed people with healing factors, though I won't state that it negates healing factors myself, but it should be more than capable of killing someone with one. To be honest, I need to go through his appearances, and now this will probably get me off my lazy bum to do so.

Let's not say "made", but was more or less enhanced and cultivated to be able drain such energies.

@jashro44: Honestly, I need to go through the Ian appearances, and gather more intel to see if I think a good defense could be made here. Ian can and has deflected gunfire with a sword before, and is really very skilled. I tend to think that if the stare isn't used all that often, and Gorgon can be tagged even with the telepathy, then Ian should have the ability to take some wins here with the bloodsword.

Jackie. He doesn't have to move, blink, speak, or even touch Kratos to put him down.

What about the stone stare bit?

The Angelus is the polar opposite of and oddly the equivalent of the Darkness. They have always been shown and stated to be equals in strength, durability, and so on. You are catching me at a point where I have not cleanly gathered all of her feats in one nice spot (she is on my to do list, I will get there, but I am working up some stuff for CaVs), but I can say that a weapon capable of taking down one of the trinity is quite powerful (since the Angelus, Darkness and Witchblade are the top dogs of Top Cow).

Luther has a kind of telepathy/body reading/foresight kind of thing kicking with levels of superhuman speed. Ian had superhuman speed before the bloodsword, was fast enough to catch bullets barehanded, and tangled with artifact bearers. The bloodsword is capable of killing godlike beings and such, and grants users enhanced stats. It has been forever since I watched Jack, but I did read some of the more recent comics with him, and his speed did not seem out of their range from that.

That's an awesome feat, but still, whether he won the fight or not, how did he fare in the fight overall? None of them were wielding the bloodsword, so if they were able to tag him and give him a good fight, then that goes a long way in making a determination.
