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. After attaining Job Level 40 they can then change to a second class job, either 2-1 or 2-2.
Once Base Level 99 and Job Level 50 as a second class, they can choose to transcend and start the process again, being rewarded with a more powerful, transcendent character.
A 2-1 or 2-2 regular or transcendent character can then chose to change to a third class, which breaks the level 99 barrier. The current maximum base and job level for third classes are 150 and 50.
Alternatively, from Novice, players can choose to become the ultimate Novice, the Super Novice, or explore one of the Expanded classes.
