I take it your group isn't playing for the home team. Sweet, in a nasty, nasty way. I can already hear this one being nick-named, "Paladin Bait." I'd like to see a player-vs.-player of those two classes going at each other.
Not necessarily an evil class. Just like a fighter version of the warlock. Upon looking at it some more, I think I need to get rid of empowered resistance. Don't need a level 5 ability, and it's pretty darn powerful.
