Crushing Prison

Enclose an opponent in a cage of telekinetic force. Each turn, they are immobilized and take 3d10 force damage. Every subsequent turn the opponent can make a STR save to escape the prison. On a successful save, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th.
