Disentropise

A thin violet ray springs from your pointing finger to a target that you can see within range. The target can be a creature, an object, or a creation of magical force, such as the wall created by wall of force.

A creature targeted by this spell must make a Constitution saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is turned into a skeletal statue of white, hard, razor sharp crystals if this damage leaves it with 0 hit points.

A disentropised creature and everything it is wearing and carrying, except magic items, are transformed into hard crystal. The creature can be restored to life only by means of a true resurrection or a wish spell.

This spell automatically disentropises a Large or smaller nonmagical object or a creation of magical force. If the target is a Huge or larger object or creation of force, this spell disentropises a 10-foot- cube portion of it. A magic item is unaffected by this spell. 

A disentropised creation of magical force shrinks by half its volume, prioritising thickness in the case of walls, shields, or other barriers. A disentropised creation of magical force becomes a construct of nigh indestrutible opaque crystal. Such constructions loose any special properties or functions ther than as an immobile, permanent object. A disintegrate spell can disintegrate 1 foot cube portions of such constructs, but they are otherwise impervious to all other forms of damage and cannot be removed aside from being wished out of existence,

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 3d6 for each slot level above 6th.
