Secret Art: Razor Hurricane

You create a rapid spinning hurricane with a 15x15 size and 50ft in height in the target location. All creatures caught in the hurricane immediately take Wind Light Damage and are pushed out of the Hurricane. Every creature that enters the hurricane immediately takes Wind Light Damage and must succeed at a save against your Potency or be pushed back 20ft. Leaving the hurricane does no damage and requires no save. Upkeep: You must spend 1 Mana and 2 AP at the start of each turn or the spell ends. When you pay this Upkeep, you may move the hurricane up to 20ft. Any creature that comes into contact with the hurricane during this move takes damage and must make a save as if they had entered it.
