Disintegration Blade

You imbue your blade with eldritch energy wreathing it in shadows. This spell lasts 1 Minute or until you land a successful attack with the weapon enchanted.

The next attack you land with this weapon forces a CON save. On a failed save, the target takes 10d6 + 40 force damage. If this damage reduces the target to 0 hit points, it is disintegrated.

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 10-foot- cube portion of it. A magic item is unaffected by this 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.
