Blast of Foam

A powerful stream of stinging cold foam springs forth from your outstretched hands towards a creature or object in range, forcing you to dig your heels in and lean against the blast to stay on your feet. The target makes a Dexterity saving throw, taking 3d6 cold damage on a failed save and being pushed 15 feet away from you. Any nonmagical fires within a 15-foot cube centered on the target are extinguished.

At Higher Levels. When this spell is cast from a spell slot of 3rd level or higher, the cold damage dealt increases by 1d6 for each slot level above 2nd, and the size of the cube in which nonmagical fires are extinguished increases by 5 feet for each slot level above 2nd.
