5th-Level Divination (Ritual)
Casting Time: 1 minute
Range: Self
Components: VSM (incense and a vial or holy or unholy water)
Duration: 1 minute

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.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you may ask two additional questions for every slot level above 5th.
