The jester forces one Medium or Small humanoid within 60 feet to make a DC 17 Charisma saving throw. If the saving throw fails, the jester and the target exchange locations via teleportation and an illusion causes them to swap appearance: the jester looks and sounds like the target, and the target looks and sounds like the jester. The illusion lasts for 1 hour unless it is dismissed earlier by the jester as a bonus action, or dispelled (DC 17).
