Wave of Disintegration

You send out a blast of magical force in a 60ft cone in front of you. A creature in the cone must make a Dexterity saving throw. On a failed save, the target takes 15d6+80 force damage. The target is disintegrated if this damage leaves it with 0 hit points.

A disintegrated creature and everything it is wearing and carrying, except magic items, are reduced to a pile of fine gray dust. The creature can be restored to life only by means of a true resurrection or a wish spell.

This spell automatically disintegrates 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 disintegrates a 25-foot-cube portion of it. A magic item is unaffected by this spell.
