Thoron

A concentrated beam of thunder erupts from your extended palm 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 Dexterity saving throw. On a failed save, the target takes 10d6 + 40 thunder 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.

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.
