Aqua jet

Through the Arcane motions of your hands you cause water to surround you, before shooting out like a jet stream in a 30 foot line from yourself. A creature caught in the line must make a strength saving throw, taking 4d6 bludgeoning damage, getting pushed 5 feet to the side and get knocked prone on a failed save. Taking half damage on a successful save and none of the secondary conditions taking effect. 

At higher level: When cast using a level 3 spell slot or higher, you can add 1d6 bludgeoning damage for every level above 2.
