Augury

You receive an omen from an otherworldly entity about the results of a course of action that you plan to take within the next 30 minutes. The DM chooses the omen from the Omens table.

Omen	For Results That Will Be...
Weal	Good
Woe	Bad
Weal and woe	Good and bad
Indifference	Neither good nor bad

The spell doesn't account for circumstances, such as other spells, that might change the results.
If you cast the spell more than once before finishing a Long Rest, there is a cumulative 25 percent chance for each casting after the first that you get no answer.
