Vaporem’s Thrashing Wave

A small violently quick wave of water streaks toward creatures within range. Choose one creature within range, or choose two creatures within range that are within 5 feet of each other. A target must succeed on a Strength saving throw or take 1d6 bludgeoning damage and be pushed 10ft away.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6)
