If you are doing the quest Second Suggestion to "obtain information from zobadi" you will have to do both quests he has. First to kill 3 mobs at sulfur mines, then to obtain oil from fogans. (there is an optional quest right beside that NPC to kill 200 fogans for a 10g bar, if you want to complete that while you are at fogans anyways.) After that you will be able to get his "information".

im fucking screaming this is so stupid
