Deep Freeze

You focus on a target or point within range and cause an eruption of jagged ice crystals to form in all directions instantaneously. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 cold damage on a failed save, or half as much damage on a successful one.

Any non-magical fires are snuffed out in the area of effect which becomes difficult terrain till the end of the next turn at which point the magical ice evaporates.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
