Jobs are your first and foremost source of income ingame. You join a Job and perform it to automatically receive ingame currency for every block you place/break or mob/player you kill depending on the Job you have chosen. You may join or leave a Job at anytime, however you are limited to being able to join two Jobs at a time. Jobs also level up similiar to Skills, although much more slowly. The higher your Job level for your current Job, the more money you will make doing that Job. The maximum level for a Job is 30. Once you leave a Job your Job level will reset to 1. Also pay attention to what actions bring in money and what take it away! Don't bankrupt yourself.
