The character can contact the character's deity—or agents thereof—and ask questions that can be answered by a simple yes or no. (A cleric of no particular deity contacts a philosophically allied deity.) The character are allowed one such question per caster level. The answers given are correct within the limits of the entity’s knowledge. "Unclear" is a legitimate answer, because powerful beings of the Outer Planes are not necessarily omniscient. In cases where a one-word answer would be misleading or contrary to the deity’s interests, the DM should give a short phrase (five words or less) as an answer instead. The spell, at best, provides information to aid character decisions. The entities contacted structure their answers to further their own purposes. If the character doesn't focus on the conversation, discusses the answers at length with other parties, or leaves to undertake another task, the spell ends.
