Water Jet

You shoot forth a burst of water in a 60-foot line that is 5 feet wide. Each target in that line must make a Dexterity saving throw. On a failure, a target takes 6d6 bludgeoning damage and, if it is huge or smaller, is pushed up to 20 feet away from you and knocked prone. On a success, a target takes half the damage, but is neither pushed nor knocked prone. If you cast this spell while underwater, a target that fails its saving throw is pushed 40 feet away and takes an extra 2d6 bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th and the distance pushed back increases by 5 feet.
