in the quest guide it says "Go back to the Duke, and he orders you to find the castle's silverware that went missing, and that unless it's returned, they'll have no option but to war against the goblins. Now it is time to use the key that you thieved from Sigmund earlier. Use the key on the chest in the room just south of the Duke and Sigmund. In that chest, you will find a set of H.A.M. Robes. Tell the Duke that Sigmund's a member of H.A.M." it practically means you gotta get the robes INSIDE of SIGMUND's chest, not any other HAM robes? =\ ill try your idea though
