Jobs refer to those martial paths that thrived in former times but have since fallen into disuse. Recent developments, however, have occasioned something of a revival in their popularity. By achieving sufficient mastery in a certain class, adventurers will be able to begin undertaking the mantle of a related job.
Once you get your main class to Level 30, you can begin to start thinking of what 'Job' you want to obtain. By leveling a class to 30 and a sub-class to 15, classes can partake in up to 9 different jobs.
Characters learn new jobs by obtaining 'Soul Crystals' that unlock once you meet the jobs particular requirements. A quest will become available from your guildmaster once you have met the requirements, which are listed below:
