Idea

The caster flips a coin into the air while thinking of a problem at hand. The coin vanished mid-spin, and the caster then gains a +5 to Arcana, History, Insight, Investigation, Medicine, Nature, Religion, or Survival ability checks needed to solve the problem.

If the problem is one that requires role-playing instead of skill roles to solve, the DM gives a hint to the solution.

Repeated castings concerning the same problem gain the same insight each time.
