Thunderwind (Aeromancer) skill

Open the umbrella and ride the wind upward. While holding down the skill key, levitate and move in the air. When the key is released, swiftly slash down with a sword, empowered by lightning, over a distance of 8 meters to inflict Atk. Power Damage and knock back foes. If the key is released before fully riding the wind upward, you'll strike down quickly over a 4 meter distance to inflict Atk. Power Damage.
