6-level Conjuration (ritual)
You swap the positions of any two creatures you can see, including yourself. They are teleported each others spots. If one or more are unwilling, they are allowed a Wisdom save. If both creatures are unwilling and one fails its save while the other succeeds, the creature who fails is instead teleported to a spot next to the creature who succeeded. If all such spots are occupied, they are teleported as close as possible. A creature being unexpectedly swapped into an enemy's threatened space provokes an attack of opportunity.
