Some deities sanctify their clerics and similarly devoted followers. This gives the follower the holy or unholy trait. The holy trait (page 456) indicates a powerful devotion to altruism, helping others, and battling against unholy forces like fiends and undead. The unholy trait (page 462), in turn, shows devotion to victimizing others, inflicting harm, and battling celestial powers. Deities that list “must choose” mandate gaining the trait and those that list “can choose” give the devotee the option to choose the trait or not. You can have the holy trait, unholy trait, or neither, but can never have both the holy and unholy traits.
