Francisca is the first of three Mage Generals you will face, the same who is also a user of the Element of Ice. Because of this, you will definitely want to have the Element of Fire on your side. It is recommended to combine the Staff Copy Ability with a Fire Element, as Francisca is extremely weak to this. Should Francisca try to use her Freeze Cannon against you, simply stand directly underneath her and attack from below. She will also like to flying around the area, freezing your allies with her attacks as she does. If she begins to do this, try to unleash as many attacks with your flaming staff as you possibly can.
