The job change system in World Breaker was relatively simple. At the start of the game, players would choose one of three basic classes: Warrior, Mage, or Artisan. After reaching certain levels, they could advance to a more powerful class. The first job change occurred at level 3, the second at level 25, and the third at level 50.
The first job change, however, was almost too insignificant to be considered an advancement. It was more of a transition from the tutorial to the actual gameplay. This system was designed for beginners, allowing them to familiarize themselves with the basic classes before moving on to the first job change. Without a basic understanding, players might struggle, which is why there was a level gap before the first job change.
