I am building a D&D 3.5e Saint Cloistered Cleric with a Vow of Poverty and Vow of Peace. In the past two weeks, I ran across a character ability (a skill, feat, spell, alternate class feature, domain ability, or something) that had wording like:
as a free action you can consult your intuition and know whether something is in accord with your god's will [or breaks a vow, I'm not certain of the exact benefit]
I remember specifically that it was a free action and it let you check the status of an action under consideration. But I've spent 3 hours searching the Book of Exalted Deeds, the Player's Handbook, and Google and can't locate it.
