Anterome's Aquatic Assualt

You create a large stream of water 15ft in diameter, originating from you, in a 30ft line. All creatures in the area when you cast it must make a Strength saving throw against your spell DC or take 3d10 bludgeoning and be pushed 10ft away from you, on a success taking half damage and not being moved. You can use a bonus action on subsequent turns to shift the direction the stream is pointed, and any creature that begins its turn in the area is forced to make another save

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you deal one additional damage dice for each level above 3rd.
