Alternate Reality

The caster creates a small variation in probabilities. This variation lasts only for a moment, but creates an alternate result for one recent event. When this spell is cast, any one event attempted by the recipient during their action is recalculated, essentially allowing (or forcing) the creature to make new die rolls.

 Only events that begin and end in a single round can be affected, and only one die roll can be rerolled. If the creature is a willing recipient, the player can choose which roll affects the target. If the creature is unwilling they must repeat the action as though it had never happened. In this case the second result, no matter the outcome can not be changed.

This spell can only be cast on a single creature once in a single round even if the recipient is targeted by a different caster.
