Water Stream

You produce a blast of powerful water from your palm. Each creature in a 30ft. long and 5ft. long line originating out from you must make a Strength saving throw, taking 2d8 bludgeoning damage on a failed save, or half as much on a successful save. A creature that fails this save is also pushed back up to 20 feet. 

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.
