Charged Wind Gale

A column of wind, charged by a drawn arrow forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw of 12DC. A creature takes 8d6 + Dexterity modifier, force damage on a failed save, or half as much damage on a successful one. If a creature fails the save, they must roll a Strength saving throw of 14 DC or get knocked back 10 feet.
