Cavitation

You warp a section of air or water that you can see within range, collapsing it in on itself. The area then violently implodes, sending a destructive wave of pressure in every direction. Each creature in a 15-foot-radius sphere centered on that point must make a Constitution saving throw. On a failed save, creatures within the area take 5d10 thunder damage and are blinded and deafened until the start of their next turn. Creatures that succeed on the saving throw take half as much damage and suffer none of the spell's other effects.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
