We just released the new professions in-game. Players will be able to set their second profession ingame via /setprofession.
When starting a new character you will execute the command twice to set both of your professions.
Since this is a new update for Gildorym, we may experiences some bugs. If you experience any errors please post your error on the bug thread (Link below). It helps staff out tremendously if you also post a screenshot of your issue/error.
