Mastery certificate description
The Freelancer is the default job class in the 3D versions of Final Fantasy III. Although Freelancers have low base attributes, they have a diverse range of equipment, able to equip many types of armor including some exclusive to a particular job. Freelancers lack particular expertise as while they can equip most weapons and armor, as well as use magic, their overall abilities are well average. They are useful in the beginning but get progressively weaker.
