Briny Jet

You blast a stream of saltwater in a 30-foot line that is 5 feet wide. Each creature in that line must make a Dexterity saving throw. On a failure, a target takes 2d6 bludgeoning damage and, if it is Large or smaller, is pushed up to 10 feet away from you and knocked prone. On a success, a target takes half the bludgeoning damage, but is neither pushed nor knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
