In iruna each adventurer is given the option to take on classes to gain abilities and stat boosts. At certain levels you can change your classes.
Tier 1: 10-20
Tier 2: 50-70
Tier 3: 120-140
Special classes can be achieved by being level 100 minimum and completing the quest for the class. But going to these special classes you forfeit any previous skills from other classes that you have obtained. And once you are a special class there's no going back. So pick your iruna career correctly
