Cube of Distraction

An intelligent creature (minimum Int score of 9) you can see which is able to manipulate things with its hands must make an intelligence saving throw (against your spell save) or become engrossed in a puzzle cube that only it can see. It is so engrossed that it takes no actions on it's next turn. On subsequent turns it makes another saving throw - on a fail it becomes frustrated and takes 1d4 psychic damage. It becomes progressively more frustrated rolling 2d4 on its next failed save, then 3d4 which is the maximum.

The spell also ends if the creature takes damage from another source.

If cast at 3rd level the damage die becomes 1d6 and progresses as above.
