Alpha's Chill of the Void

You bring forth a wave of airless, supernaturally-intense cold in a 60-foot cone. Each creature in that area must make a Constitution Saving Throw, taking 7d6 cold damage on a failure or half as much on a success.

If a creature fails its saving throw by 10 or more, it takes a level of exhaustion as the air is ripped from its lungs.

All normal vegetation of Medium size or smaller in the area dies. Larger vegetation has a 50% change of dying as well. Fires in the area are immediately snuffed and standing water instantly freezes.
