Waterball

Materializes and hurls a mass of water from your pointing finger to a point you choose within range and then explodes on contact. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 2d6 bludgeoning damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 2d6 for each slot level above 2nd. The range also increases by 10 ft. for each slot level above second.
