Commune

You contact your deity or a divine proxy and ask up to three questions that can be answered with a yes or no. You must ask your questions before the spell ends. You receive a correct answer for each question. Divine beings aren't necessarily omniscient, so you might receive "unclear" as an answer if a question pertains to information that lies beyond the deity's knowledge. In a case where a one-word answer could be misleading or contrary to the deity's interests, the DM might offer a short phrase as an answer instead. If you cast the spell two or more times before finishing your next long rest, there is a cumulative 25 percent chance for each casting after the first that you get no answer. The DM makes this roll in secret.

This spell puts the caster in contact with his patron deity or an extraplanar servant thereof, who answers one yes-or-no question per caster level. The ritual to cast this spell takes 1 turn to complete. The being contacted may or may not be omniscient, and further, though the being is technically allied with the caster, it may still not answer questions clearly or completely. These details are left to the GM's discretion.
