Classes
From Xeliki
In Ragnarok Online, a character's abilities and skills are defined by their class (also known as job). Characters start out as Novices, then once they reach job level 10 they can choose between a variety of first job classes. Once they then reach at least job 40 they can then change to a second class job, either 2-1 or 2-2. Then after reaching 99 base level and 50 job level as a second class they can choose to transcend and start the process again, being rewarded with a more powerful, transcendent character.
