Bitter Wind

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.
At Higher Levels. When you cast this spell using a spell
slot of 4th level or higher, the saving throw is made with
disadvantage, and the damage increases by 1d12 for each
slot level above 3rd.
