Memory of Nothing

With a look and a gesture, you turn a thinking creature's mind against itself, causing the creature to struggle to remember how to perform more complex actions. Choose a target within 30 feet and spend a Mythic Point. The target must attempt a Will save against your class DC or spell DC (whichever is higher) at mythic proficiency.

Critical Success The target is unaffected.

Success For the next 3 rounds, if the target performs an activity that requires three or more actions, they take 12d8 mental damage.

Failure For the next 3 rounds, if the target performs an activity that requires two or more actions, they take 12d8 mental damage.

Critical Failure As failure, but the target is also Stunned 1 as its mind struggles to function.
