Seeing as many people think the new paladin enhancements aren't quite enough of a boost, I've come up with an idea for an enhancement.
As paladins are primarily combatants versus the forces of evil, such as undead and evil outsiders, how about giving them a couple of enhancements that can apply their aura as an equal penalty to undead and evil outsiders respectively.
It would be something relatively new and situationally useful. So what do you think?
