Cyclonic Lance

Channeling the surrounding air into an unstoppable, cyclonic force, you strike forward in a straight line to an unoccupied space within 30 feet. The movement does not provoke opportunity attacks.

Make a single Melee Attack roll. During the surge, any creature's space you pass through, or within your melee range of, takes 4d12 Slashing damage if the attack would hit, or half on an attack miss. 

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