Sentence to the Void

You attempt to sentence one creature that you can see within range to a life of eternal imprisonment until the end of Time. The target must succeed on a Charisma saving throw or gain a Detainment Chance of 20%. Each time the target takes damage, it rolls a d100, and if the roll is equal to or less than its current Detainment Chance, it is instantly sent to the Void.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target one additional creature for each slot level above 5th.
