Anomalous Enrapture

You choose a creature within your sight. Within their mind they are enraptured in a spatial anomaly that folds in on itself infinitely on a fractal within the edge of an infinite void.

The creature must succeed on an intelligence saving throw. If they succeed on the save, they are stunned until their next turn or when they next take damage, whichever happens first. If they fail the save they lash out on their surroundings, using their next action to attack the closest creature to them (at disadvantage) with a melee weapon attack or spell attack with a cantrip. They continue to lash out until they are damaged, at which point they may make an additional intelligence saving throw, at which point, if they succeed, they are released from the spell.
