You slice the air, creating a sharp blast of wind that shoots out from you. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 slashing damage on a failed save, or half as much damage on a successful one.

When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
