Conjure True Vacuum

Creates a magical bubble containing a sphere of True Vacuum with a diameter of up to 1 foot. Nothing can exist within this sphere. All matter, energy and information caught inside it is instantly destroyed, along with anything that enters it for the duration. Creatures destroyed by the sphere cannot be brought back to life as their souls have been annihilated by the sphere.

On your turn, you can use an action to move the sphere up to 10 feet in any direction and a bonus action to increase or decrease the diameter by up to 5 feet, to a maximum of 30 feet. A moving sphere annihilates everything in its path.

The spell can only be dispelled safely if you use a bonus action on your turn before the spell duration runs out. The sphere must be at most 5 feet in diameter to be safely dispelled. If you let the duration run out, you must succeed on a DC 10 saving throw of your spellcasting ability to safely dispel the sphere. If the sphere is affected by any spell that would dispel it you must immediately succeed on a DC 15 saving throw of your spellcasting ability to safely dispel the sphere. If you fail on either saving throw or if you lose concentration on the sphere, only the bubble containing the sphere is dispelled and the sphere of True Vacuum will start to expand in all directions at a rate of 5.901.426.339 feet per turn.
