Thane’s Planar Transference

Small, unstable rifts to the outer planes appear around and pull at two creatures you can see within range (can target self). An unwilling creature must succeed on a Charisma saving throw to resist the spell. All creatures that fail the saving throw swap places with the other target of the spell and if they were unwilling, the creature takes 4d6 force damage. On a success, neither creature changes positions and the unwilling creatures take half damage.

If a creature were to be falling after being teleported by this spell, it descends slow enough to the ground that it does not take any falling damage, as with the feather fall spell.
