Vacuum Bombardment

You fire a small explosive sphere of arcane energy at a creature within range of the spell. Make a ranged spell attack against the target. On a hit, the target takes 4d10 energy damage and must make a Strength saving throw. On a miss, the target is knocked prone (if it is Large or smaller), and each creature within a 10-foot radius around it must succeed on a Dexterity saving throw or take 4d6 energy damage and be knocked 5 feet away from the original target. On a success, the creature takes half damage.

At Higher Levels. When you cast this spell by spending mana points equal to a spell of 4th level or higher, the damage increases by 1d10 for each spell level above 3rd. When cast as a spell of 5th level or higher, this spell’s damage becomes runic.
