Augury

You receive an omen from an otherworldly entity
about the results of a specific course of action
that you plan to take within the next 30 minutes.
If you cast the spell two or more times before
completing your next long rest, there is a
cumulative 25 percent chance for each casting
after the first that you get a random reading.
Material: Specially marked sticks, bones, or
similar tokens worth at least 25 gp
