Think D&D style here, maybe. He's physically powerful, and quite fast. He'd have good fortitude and reflex saving throws against negative effects. But willpower might be his weak spot, so mental effects could do him in a bit easier than other things. It's also pretty heavily foreshadowed by now that the sister has more potential than him, so I kind of feel like she might need more "exp" to level up than he does.Wtf? He’s a fair bit stronger than her, physically at least, and yet he can’t resist at all? Isn’t that ability WAY too op?
