There are 4 different classes, Warrior, Mage, Archer, and Thief. At level 20, you will be able to accept your job advancement quest line. It is reccomended that you do some research on your job advancements before choosing.
First, you will have to choose from your available job advancement classes* you must go around Bearded Whale Coast and kill any enemies there until you have 20 Class Emblems. Next, you must defeat Captain Hookah on 2 Star (F2) difficulty. Finally, Defeat Hookah on 4 Star (F4) difficulty.**

- Archers can become Hunters or Rangers. Hunters use Bows while Rangers use Crossbows.
