Transposition

Choose a creature that is Large or smaller, or an object no larger than 5 feet in any direction, that you can see within range. You and the target immediately swap places upon casting the spell. If the target is a creature, they may make a Charisma saving throw to negate the spell's effects.

If you or the target do not fit in the space you are being teleported to, both you and the target take 3d6 force damage, and the spell is wasted.
