no one says anything about Brother Verulus (the guy who is supposed to get fed to the cannibals). I havent played a ton with him since I got him but he is pretty bad ass. Also not positive he is immortal, but I would assume he is a quest ender like Barbas is so I would think he is.

I will play him more tomorrow as I might go back to my 'main' guy for the day. Will update on whether or not he is really immortal or not. But he is a caster anyway so even if he isnt his chances of getting hit by you to kill him are slim anyway.
