Disintegrate

You launch a green ray at a target you can see within range. The target can be a creature, a nonmagical object, or a creation of magical force, such as the wall created by Wall of Force. A creature targeted by this spell makes a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 Force damage. If this damage reduces it to 0 Hit Points, it and everything nonmagical it is wearing and carrying are disintegrated into gray dust. The target can be revived only by a True Resurrection or a Wish spell. This spell automatically disintegrates a Large or smaller nonmagical object or a creation of magical force. If such a target is Huge or larger, this spell disintegrates a 10-foot-Cube portion of it.

Using a Higher-Level Spell Slot: The damage increases by 3d6 for each spell slot level above 6.
