Arte History and Description
When this arte is used, Estelle thrusts directly into the enemy before launching herself backward and into the air at an angle. This arte's movements are similar to Flying Dragon used by Leon Magnus and Snipe Roar used by Rutee Katrea, both from Tales of Destiny. Air Divide is learned as an altered arte, available for use if the "Alembic" skill is equipped while using Dividing Edge until the arte is mastered. After this, Air Divide is available as a separate arte that does not require the skill to be equipped in order to be used.
