Aqua Blast

A blast of gushing water is pulled from the depths of the Elemental Plane of Water. This water shoots from your hands in a line of 120 feet long and 5 feet wide out from you in the direction you choose. Each creature in that line of fire must make a Strength saving throw. On a failed save, a creature takes 6d12 bludgeoning damage and is pushed 30 feet directly away from you. On a successful save, a creature takes half damage and is only pushed 15 feet away from you. 

At Higher Levels: When you cast this spell using a slot of 7th level or higher, the initial damage increases by 1d12 for each slot level above 6th./
