Duelist's Domain

One creature you can see within range must pass on a Charisma Saving Throw or be transported with the caster to a harmless, demiplane. When the spell ends, both the caster and the target return to the space they departed from at the spell's casting, or the nearest unoccupied space if that space is occupied. A target automatically fails the Saving Throw if they are within 5 feet of the caster. The duration of this spell cannot be reduced by any means, including from the caster. Additionally, if the target is killed while in the demiplane, the caster recovers the Spell Slot used to cast this spell.
