A 5-foot-diameter swirling ball of ice and winds appears in an unoccupied space of your choice within range and lasts for the duration. Any creature that ends its turn within 5 feet of the sphere must make a Constitution saving throw. The creature takes 1d8 cold damage on a failed save, or half as much damage on a successful one. In addition creatures who fail the save are blinded until the end of their next turn.

As a bonus action, you can move the sphere up to 30 feet.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
