Final Fantasy XI brings back the job system, which was last used in Final Fantasy V. The job system allows you to actively shift your character’s job class whenever you see fit. You can begin your quest as a Warrior and then shift to a White Mage if you want to. All you have to do to change your job is simply go to your Mog House (yes, the very same Mogs that have been a staple in many Final Fantasy games) in the residential district of whichever city you have allegiance to. At your Mog House you can not only change jobs, but also store surplus items, place furniture and other things. Changing your job is an important part of building your character as it unlocks the ability to create support jobs (which allows you to essentially have two jobs at once and mix their abilities) or even become a special job class, like a Ninja, Bard or Summoner.
