Cone of Oblivion

9th-level transmutation

Casting Time: 1 action

Range: Self (30-foot cone)

Components: V, S, M (the ash from a disintegrated creature)

Duration: Instantaneous

A cone of terrible energy spreads out from your hand. Creatures in the area must make a Constitution saving throw. On a failed save, a creature takes 20d6 + 40 force damage. If this reduces a creature to 0 hit points, it is disintegrated.

A disintegrated creature and everything it is wearing and carrying are reduced to fine ash. If a magical item is affected by the spell, it may make a Constitution saving throw of its own, being reduced to ash on a failed save.

Objects within the affected area are automatically disintegrated.

Large or larger objects that are not completely in the cone are only reduced to ash in the spell’s area of affect.

Living creatures and objects can only be restored by true resurrection and wish or similarly powerful magic. The cone cannot pass through a globe of invulnerability or an antimagic field, which block the cone from passing through them.
