Aquajet

You create a pounding pulse of water from your palm, stretched outward towards your enemies. Each creature in a 30 foot long and 5 foot wide line centered on you must make a
dexterity saving throw. Each creature that fails the save takes 2d6 cold damage and is completely doused in water. This water extinguishes any non-magical flames affecting the creature or that they are carrying. A creature that succeeds on its saving throw takes half damage and is not covered in water

At Higher Levels When you use a spell slot of 2nd level or higher to cast this spell, it does 1d6 additional damage per spell slot used above 1st.
