Corallian's Blasting Bolt

You gather magical energy and unleash it in the form of a crackling, blinding-bright bolt of power. Choose fire, acid, lightning, thunder, cold, radiant, necrotic, force or psychic damage. Whichever damage type you selected is the damage type that the bolt inflicts. The bolt immediately rockets to a point you choose, and explodes violently with a loud crackling noise in a 10-foot-radius sphere.

A creature within this spell's area must make a Dexterity saving throw. On a failed save, the target takes 15d10 + 50 damage of the type that you selected. The target is annihilated in a different horrific way depending on which damage type it was dealt if this damage leaves it with 0 hit points.

Fire - The creature and every item it was carrying is completely incinerated, leaving virtually no trace of their prior existence save for ashes.
Acid - The creature and every item it was carrying is dissolved instantaneously, leaving nothing but a bubbling mass of clear liquid.
Lightning - The creature and every item it was carrying is charred and blasted apart, leaving only a mass of molten, ionised material.
Thunder - The creature and every item it was carrying is shattered into millions of pieces, and scattered in random directions.
Cold - The creature and every item it was carrying is frozen and then cracks suddenly, leaving only frigid chunks behind.
Radiant - The creature and every item it was carrying is seared down to the atom, leaving absolutely nothing that would indicate their prior existence.
Necrotic - The creature and every item it was carrying wilts and withers into nothingness, leaving only dead, black dust as any indication of their prior existence.
Force - The creature and every item it was carrying is disintegrated completely, and reduced to only fine grey dust.
Psychic - The creature and every item it was carrying rupture and explode violently, leaving nothing but various parts of said creature and items lying twisted and irreparable.

An annihilated creature and everything it is wearing and carrying, except magic items, are left in a totally irreparable state. A creature annihilated by this spell can be restored to life only by means of a true resurrection or a wish spell.

This spell automatically destroys a Large or smaller nonmagical object. If the target is a Huge or larger object, this spell disintegrates a 10-foot-radius portion of it. A magic item is unaffected by this spell.
