When I saw the Antipaladin, I figured upon first inspection that it wouldn't be that different to play in a game versus a PF paladin. Then I saw Aura of Cowardice and I was a little surprised! Creatures that are within 10 ft that are normally immune to fear lose that immunity?! Sure, that means you negate a paladin's aura of courage, but what about undead or construct traits that make them immune to fear? How far does this thing go? There's no save, no SR because this thing is an SU ability and it's always on.
What are your thoughts on this?
