Sphere of ultimate destruction

Sphere of ultimate destruction is a very powerful sorcerer and wizard spell that conjures a featureless black sphere of nothingness that destroys everything in its path.

Effects
Creatures who are struck by the sphere have a slim chance of surviving, but will most likely be disintegrated, along with any non-living matter. Upon striking a creature, the sphere will stop moving and wait to be directed to a new target by its caster. If the sphere moves beyond the range of the spell, it winks out of existence.

Components
In addition to verbal and somatic components, this spell required a pinch of dust from a disintegrated creature.

History
The history of this spell is unknown, but it was in common use in the Unapproachable East some time around 1373 DR.
