Water Spray

You cause water to shoot out with force in a direct 5ft wide line from an object or creature you touch for 100ft.  The water continues to move until the spell ends, when you become incapacitated, or if you choose to end it early.  If the water is from a water source, once it moves beyond the spell’s area, it resumes its flow based on the terrain. If the water is created, it disappears past 100 ft.  

Any creature in the water spray must make a Dexterity saving throw against the spell caster's spell save DC or take 4d8 bludgeoning damage and 2d6 cold damage on a failed save and be pushed back 15ft and knocked prone.  On a successful save, the creature takes half as much damage and is not pushed back or knocked prone.

At 6th level or higher, add an additional 1d8 bludgeoning damage and 1d6 cold damage for every spell level above 5th.
