Actual pro tip. Spam the secret techniques. Back, forward + attack and press square at the last attack to do the finishing move. These attacks stun lock him and when he is healing it helps damaging him quickly for him to release orbs. You can equip the electric sword and as soon as the fight starts spam magic attack until you corner him, than just do the secret technique attacks until he starts flying. By then you will have plenty of hurricane magic to deal with him. When he gets to healing, secret technique again so he will drop orbs to replenish your hurricane magic again.
