Ethereal Swap

Ethereal smoke shrouds your body as you are pulled from the material plane. Before the smoke can even dissipate another creature lies prone where you once were. As an action, you can attempt to swap places with a single medium or smaller creature in range. If the creature is willing, there is no save and lands safely on their feet. However, if the creature is unwilling, they must make a Charisma save against your spell save DC. On a failed save, the creature instantly swaps places with you, takes 1d6 bludgeoning damage, and falls prone
