There are a total of twelve different jobs in the game and once you assign a character to a job, you will be stuck with that job unless you visit and speak to Montblanc in the Clan Hall of Rabanastre. You’ll gain access to your first job shortly into the game, but you’ll be able to assign another job to each character after advancing the story sufficiently. This is done by purchasing a specific license on the initial License Board you pick.
You will have access to all abilities and equipment from the two License Boards, plus all abilities, stats and equipment are shared across both of them. For example, if you purchase one of the Swiftness licenses on one board and the other has it, then it will be purchased on both boards. This is a good thing, as it has potential to bypass having to get certain Quickenings or Espers, which will sometimes have licenses locked behind them. It gives you more versatility and it makes choosing complementary jobs very important, indeed. You can also choose a job for more than one character if you want, as you don’t need to go with all twelve jobs. So, if you wanted to make everyone a White Mage, you could!
Of course, strength often lies in diversity, and being able to utilize multiple types of arms, armor, magicks and technicks will arguably give you the best chance of handling whatever foes lurk in Ivalice. With two jobs per character at your disposal in The Zodiac Age, diversity shouldn’t be as much of an issue as balancing your party and picking job combinations that enhance each other. It is to this end this chapter is dedicated, and every job will be discussed in detail, including what licenses they provide and what other jobs pair up well with them.
