what about a paladin spell called Smite?....Would be an anit-vampire skill that would cause X holy damage toward the vampire in question....enchants main hand weapon to do x damage only applicable to vampires?

Why only vampires Juba? Just curious if this could perhaps be extended to all undead so Paladins can maintain life in the world.

I'm not keen on vamp only since vamps aren't a strong feature at the moment, but perhaps as an attack against evil. Rather than making it a spell, it could be a skill, and the hand would recharge and when ready would inform the paladin at which time they could "smite <evil creature>" for a hefty attack.
