You guide others on the path of enlightenment, leading by example. You gain the ability to expend ki to smite 'tainted' creatures (aberrations, extraplanar creatures that are not Lawful Outsiders, and undead). You gain +2 to Diplomacy, Heal, and Intimidate, and a permanent Protection from Tainted Creatures effect (warding against mental domination and granting a +2 deflection bonus to AC and a +2 resistance bonus to saves against attacks from extraplanar creatures, aberrations, and undead). Your unarmed attacks now bypass Byeshk damage reduction.
