Obedience
Spend an hour meditating on something you’ve learned and whispering hypotheses and possibilities based upon that fact. Additionally, once per week, you must perform an act you’ve never done before and that society holds as taboo—usually involving eating or drinking something unsavory. You can attempt a saving throw to disbelieve any illusion you come within 10 feet of, and you gain a +4 bonus on Will saving throws to disbelieve illusions.
