Chilling Wind

A burst of Icy-Cold wind, 30 feet long and 15 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 15 feet away from you in a direction following the line. Those who get pushed back also take 2D6 cold damage. 

While in contact with a Chilling Wind, your movement speed is halved, and you take 1d6 cold damage every turn you start there.
