Cavitation Bubble

You conjure a bubble of water and launch it at high speeds at a creature you can see within range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 thunder damage. When cast upon a creature within 5ft you don't have disadvantage on the attack, and when underwater you can cast the spell as a bonus action.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
