Water Bolt

You hurl a whirling water ball at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 bludgeoning damage and must succeed on a Strength saving throw against your Spell Save DC or knocked prone.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
