Initiation Time: 1 action
Range: 60 feet
Duration: Instantaneous
You conjure up a wave of water that crushes down on an area within range. The area can be up to 30 feet long, up to 10 feet wide, and up to 10 feet tall. Each creature in that area must make a Strength saving throw. On a failed save, a creature takes 4d8 bludgeoning damage and is knocked prone. On a success, a creature takes half as much damage and isn't knocked prone. The water then spreads out across the ground in all directions, extinguishing unprotected flames in its area and within 30 feet of it.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 1d8, and the length, width, and height of the wave increases by 5 feet for each level above 3rd.
