Aquajet

Water or a similar liquid pools in your hand and then pulses out towards your enemies. Each creature in line 30 foot long and 5 foot wide line emanating from you must make a Dexterity Saving Throw. A creature takes 2d6 cold damage on a failed saving throw, or half as much damage on a successful one.

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