Disintegration Wave

You invoke the raw destructive force of the Disintegrate spell, and channel it outwards in a deadly wave of green energy. The blast effects everything within a 30 foot radius centered on you. All creatures within that sphere must make a Constitution saving throw. On a failure, the creature takes 10d6 + 40 Force damage. If this damage reduces the target to 0 hit points, it is disintegrated. The spell automatically disintegrates any Large or smaller nonmagical objects and creations of magical force within the spell's radius that are not being carried.  If a Huge or larger object or creation of magical force is within the radius, this spell desintegrates whatever portion of it is within the sphere. A disintegrated creature and everything it is wearing and carrying, except magical items, are reduced to a pile of fine grey dust. The creature can be restored to life only by means of a True Resurection or a Wish spell.
