A wave of water sweeps out from you. Each creature in a 15-foot cube originating from you must make a Strength saving throw. On a failed save, a creature takes 2d8 bludgeoning damage and is knocked prone. On a successful save, the creature takes half as much damage and isn't knocked prone.

In addition, unsecured objects that are completely within the area of effect are automatically knocked over by the spell's effect.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
