Blue Mages are a unique class that can learn any enemy skills that they experience. They may record more enemy skills in their skill log as their level increases. One of these skills may be used as your action for the day, once acquired. All enemy skills cost the user the consolation exp points per use.

This class is attainable after using the Blue Mage's Medal.
