Cold Mist

You create a 20-foot-radius sphere of cold mist centered on a point within range. The sphere spreads around corners, and its area is lightly obscured, It lasts for the duration or until a wind of low or greater speed (at least 5 miles per hour) disperses it. Any creature within this mist must make a Constitution saving throw. On a failed save, the creature has disadvantage on the next ability check it makes before the end of its turn. Creatures with resistance or immunity to cold are also immune to this effect.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the radius of the mist increases by 20 feet for each slot level above 1st.
