Decinerate

A work of magic that doesn't evoke an intense fire as many suppose, but is rather a sophisticated spell whose primary function is to disperse and diffuse at a very fine level, and which produces an incredibly intense heat as a side effect of its peculiar structure. When you cast the spell, a livid bluish-white beam of fire lances forward at a target you can see within range. The target can be a creature, a non-magical object, or a creation of magical force, such as the wall created by Wall of Force.

A creature that is targeted by this spell makes a Dexterity saving throw: on a success, the target takes half damage; on a failed save, the target takes 15d4 + 40 Fire damage. If this damage reduces it to 0 Hit Points, it and everything non-magical it is wearing and carrying are disintegrated into fine gray ash. The target can be revived only by a True Resurrection or a Wish spell.

This spell automatically disintegrates a Large or smaller non-magical object or a creation of magical force. If such a target is Huge or larger, this spell disintegrates a 10-foot Sphere portion of it.

Using a Higher-Level Spell Slot. The damage increases by 5d4 for each spell slot level above 6.
