Biting Winds

A line of piercing wind blasts out from your hand in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 6d8 slashing damage and is knocked prone. On a successful save, it takes half as much damage and isn't knocked prone by this spell.

You can create a new line of wind as your action on any turn until the spell ends.

For the duration, buffeting winds swirl around you. Ranged attacks against you have disadvantage.
