Breaking Waves (Sea)

Crashing waves of water break against a target within range. Make a ranged spell attack roll against the target. On a hit, the target takes 1d6 bludgeoning damage and must succeed on a Strength saving throw or be knocked prone.

This damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
