Why did you give up on stuns? - I'm planning to kill with attacks. Stunning a corpse doesn't make sense.

Well, statistically, you'll have one corpse every four turns. And that's without considering various parries, blocks, dodges, and negations. With paralysis, your opponent will either be dead or countered in half the cases. Decapitation only has one charge.

But you can take evasion.

It will be much more useful than decapitation in your case.

add everything from willpower to dexterity.

I wouldn't advise it.
