Diabolical oaths usually can only be accessed as a result of a meeting with a true devil, or after performance of a heinous incantation. A character that has taken a diabolical oath radiates an aura of evil equal to a cleric with levels equal to his hit dice. In the case of Devotee of Darkness and Soulsworn, the patron of the oath has the ability to revoke the oath at any time.

Only the most powerful servants of Good can otherwise release a character from the effects of a diabolical oath; the method of such a release is detailed in the oath’s description. In either case, though, once the diabolical oath has been spurned, no new feat is gained in its place.
