Maze

Banish one creature you can see within range into a labyrinthine demiplane. The target remains there until the effect ends or it escapes by using its action to make an INT (Investigation) check against your power save DC. On a success, it returns to its former space or the nearest unoccupied space.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
