Schuler’s Wasting Oubliette

When you cast this spell, choose one Large or smaller creature within range that you can see, focusing on the intention of punishing the creature. The target must make a Charisma saving throw, and on a failed save, vanishes with a faint popping noise. The target is teleported to a small demiplane for the duration of the spell, which takes the form of a 10-foot cube with polished stone walls, a stone floor, and a ceiling of metal bars, through which filters dim lighting. The walls, floor, and bars are immune to all damage, and can not be destroyed. Time in this demiplane works differently, with one hour passing for each minute that passes in the Material Plane. Creatures in this demiplane do not require air, food, or water for the duration, do not age while they remain here, and can not benefit from short or long rests. At the end of the spell, the target returns to a randomly determined unoccupied space within 10 ft. of yourself. If there is no unoccupied space in that range, the target reappears in the nearest unoccupied space.   At Higher Levels When you cast this spell using a spell slot of 6th level or higher, you can maintain concentration on the spell for 1 hour, and when cast using a spell slot of 8th level or higher, you can maintain concentration on the spell for up to 24 hours.
