Waterjet

You hurl a jet of pressurized water towards a creature within 60ft. The target must succeed on a Strength saving throw or take 1d6 bludgeoning damage and be knocked back 5ft. Against targets that are underwater, the range of the spell is doubled to 120ft. and targets that fail the saving throw are instead knocked prone.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
