Okay. So. Deathmaster isn't in the mafiascum wiki. Even so I don't put it past anyone to create a super-power role so let's pretend for the sake of conversation that Warrior is telling the truth. If all night kills are deflected then he can die by lynching. Okay... he also says part of this role gives him night kills. And he doesn't claimed to be either town or mafia aligned, so this role is probably a survival win. Why the hell would we keep anyone with a nightkill ability who isn't pro-town?
I don't believe this roleclaim, but I also don't trust Warrior as far as I can throw him because he's rogue and he's a bullter (an epic funny one, but nonetheless.)
So ##vote: The Ultimate Warrior because either way he's not in it for a town win.
