Classes are character jobs with unique abilities and can take on the role of melee, ranged, or magic types. Each class has different sets of skills and wields a unique weapon that depends on the type. Classes are not gender locked and can be changed at any time outside of combat, assuming the class has already been unlocked.
The class level is a separate leveling system from the character level. Each class has its own class leveling system. thereby requiring characters to level up each class in order to access the corresponding class skills and other abilities. The class level cannot exceed the character level.
