Freezing wind, forming a line 120 feet long and 20 feet wide, blasts from you in a direction you choose for the spell’s duration. Each creature that starts its turn in the line must succeed on a Strength saving throw or be pushed 30 feet away from you in a direction following the line. Creatures that fail the saving throw also take 1d12 cold damage and are knocked prone. If cast during cold weather or in dark or shadowy conditions, the saving throw is made with disadvantage. Any creature in the line must spend 2 feet of movement for every 1 foot it moves when moving closer to you.   As a bonus action on each of your turns before the spell ends, you can change the direction in which the line blasts from you.   The bitter wind disperses gas or vapor, and it extinguishes candles, torches, lanterns, and similar flames in the area.
