Blasting Bubble

You inflate a roiling bubble of water and send it flying at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 bludgeoning damage. Hit or miss, the bubble then explodes. The target and each creature within 10 feet of it must succeed on a Strength saving throw or take 2d8 thunder damage. If one of the creatures around the original target fails the saving throw, they are also pushed 10 feet away from the original target. A target immersed in water has disadvantage on the saving throw.
