Eh, it's mostly Loss who's Chaotic Evil, and while she sorta runs the Slaughter Tribe, she doesn't really bother to be picky about who joins or how they build their characters. Personally I was going to make the NPC's Neutral Good and act as Loss's conscious, and hopefully she'll help keep Loss in check if/when she has to collaborate with the other guys. The NPC also belongs to Loss too, if that matters.

Also I'll adjust the other stuff too. With Disruptive attack it's more like "Whenever you cast a spell near Loss, she gets a swing at you". The attack itself may or may not be able to actually stop the spell from happening, but getting slashed in the face might. Using D&D terms, think of it as Loss always being allowed to take an attack of opportunity against someone using a spell in melee, even if they cast defensively. As for the axe it's mainly able to sunder lingering magical effects like buffs and such, or things like mind control on an ally. It can't be used to do stuff like, sunder through a fireball or stop healing magic.
