Sphere of Ultimate Destruction

A 5-foot diameter sphere of pure void and annihilation appears in an unoccupied space of your choice within range and lasts for the duration. Any creature that ends its turn within 5 feet of the sphere must make a Dexterity saving throw. The creature takes 10d6+40 force damage on a failed save, or half as much on a successful one. A creature brought to zero hit points by this spell is disintegrated as if affected by the Disintegrate spell.
As an action, you can move the sphere up to 60 feet in any direction. If you ram the sphere into a creature as part of moving the sphere, that creature must make the saving throw against the sphere’s damage, and the sphere stops moving this turn. Any unattended non-magical object that is Large or smaller is automatically disintegrated if rammed by the sphere.
