Crystallize

You create 10ft radius burst of Crystal centered at a point within range. Each creature within range must make a Dexterity saving throw of 17. On a failed save the target takes 4d6 piercing damage. The creature is incapacitated and has a speed of 0 as they are encased in crystal. The creature encased cannot attack or use spells, and cannot be attacked or affected by spells. A creature encased in the Crystal can make strength saving throw of 17 breaking free of the crystal. Additionally each Crystal has an AC of 13 and 25 Health. Once the Crystal is destroyed the creature is immediately released.
