Chronal Exile (Chronomancy School of Magic)

With a glimmer, you activate a large spinning top which whirls in front of you in the air. When you speak the name of a creature within range, it must succeed on a Charisma saving throw or be sent howling into the riptide outside of linear time. It ceases to exist for the duration. If it is on its native plane, it has advantage on this saving throw.

If the target succeeds on its saving throw, the spell ends with no effect and the creature is immune to this spell if you cast it again. When you cast this spell, any previous casting of it ends, meaning that you can only exile one creature at a time.

This spell continues for the life of the caster. Once it ends, the creature returns to the exact location it was removed from existence.
