Dark Abyss

You force a creature within range to make a Charisma saving throw. On a failed save, the target is teleported to a demiplane that is a featureless black void, where it falls continually until the spell ends. When the spell ends, the target returns to the space it occupied before you cast the spell or, if the space is occupied, into the nearest unoccupied space. The creature lands prone as if it had fallen 50 feet, suffering 5d6 bludgeoning damage, unless the creature can fly and hover or can otherwise mitigate falling damage.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, it affects one additional creature for every two slot levels above 4th.
