Nothing is sacred. You are unbound by the beliefs of man, enabling you to operate outside of culture's manufactured boundaries.
You are immune to mental-affecting abilities and statuses (such as Dread and Euphoria), and you are more effective using your mind-affecting abilities on others.
A sarira left behind by a Nihilism monk will grant its bearer a bonus to defense against mind-effecting abilities.
