Waterball

A ball of water flies from you to a point you choose within range and then explodes into a burst of water upon impact. Each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 8d6 Bludgeoning damage on a failed save or half as much damage on a successful one.

Creatures nearby are [Tooltip Not Found].

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
