You create a 30ft cube whose edges have a total of 12 glowing purple and blue portals. Creatures inside the cube must make a Wisdom saving throw or be charmed by the portals. Any creature charmed by this effect must spend their turn moving towards the nearest portal and stepping through it. Upon stepping through, roll a d12. The creature reappears at another portal in the area, using the original portal they stepped through as a 1, counting clockwise. Upon travelling through a portal, the creature suffers 4d8 psychic damage. Creatures affected by this spell may attempt a new Wisdom saving throw at the end of their turn to end the effect.
At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
