Bravely Default/Jobs

Initially, each character starts off with the Freelancer job. As you progress through the story and earn asterisks from defeated bosses, you will unlock more jobs. There are 24 jobs that can be unlocked. Jobs have levels that can be raised by earning JP from battles. Each level gained unlocks a new ability. Each job is mastered at level 14. Jobs can be switched in the Job menu and any progress of the previous job is saved. When you change the job of a character, you will also want to ensure you change their abilities and equipment.

Magic
Some jobs, such as the black mage and white mage use magic for their commands. You need to purchase scrolls before you can use magic. Only one scroll is needed to unlock for all characters.
