You summon a blast of bitter cold wind. Each creature in a 90-foot cone must make a Constitution saving throw. A creature takes 12d8 cold damage on a failed save, or half as much damage on a successful one.

The bitter cold freezes nonmagical liquids within the area that aren't being worn or carried, and it extinguishes nonmagical flames and any magical flames created by a spell cast with a slot level lower than the one used to cast this spell.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 2d8 for each slot level above 7th
