Vapor Fist

You punch your fist in the air, causing a tremor in the water vapor in range. Each creature other than you in that area must make a Dexterity saving throw. On a failed save, a creature takes 2d6 bludgeoning damage and is knocked prone.

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