Blizzard

You conjure a swirling blizzard that fills a 30-foot radius sphere, centred on a point you can see within range. The blizzard lasts for the duration. The blizzard's area is difficult terrain, and extinguishes exposed flames in its area. Creatures fully within the blizzard's area are blinded and deafened.

A creature that starts its turn in the blizzard's area or that enters the blizzard's area for the first time on a turn must succeed on a Constitution saving throw, or suffer a level of exhaustion. A creature that has resistance to cold damage makes this saving throw with advantage, and a creature with immunity to cold damage succeeds on the saving throw automatically.

While the spell lasts you can use an action on each your turns to move the blizzard up to 30 feet in a direction of your choice.
