Eki-Eki's Blizzard

You conjure a small blizzard centered on yourself with a radius of 20 ft. You are considered heavily obscured and have 3/4 cover, and ranged weapon attacks have disadvantage against you. While within the area of the blizzard the ground is considered difficult terrain to any creature other than you. Any creature within the blizzard other than yourself must make a Strength saving throw or take 2d6 cold damage and be knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radius of the spell gets larger by 5 ft., and the cold damage increases by 1d6 for every spell slot above 3rd.
