Thieving Guild

In order to do thieving guild jobs, one first needs to complete the Thieving Guild Trail quest, located in Mentan on Mezno Island. Once you have completed the quest you will be accepted into the Thieving guild. From then on you can ask them for a job at Mentan. 

When you ask the Thieving guild for a job you will be given the assignment to thieve a random (online) player within a certain time limit. They will also tell you where he or she was last seen (if you forget, click on "Quests" in the left menu). Once you have attempted to thieve him or her (you do not need to be successful) return to the thieving guild to collect your reward. You will gain some thieving experience as well as some gold pieces. The faster your complete the job, the more thieving experience and gold pieces you get!. 

For more information, see our Thieving Guide.

NB: if your target goes offline, you can return to the thieving guild and ask them for a new job (since you cannot thieve offline players).
