|A medium cog.|
Medium cog is an item used in the Elemental Workshop II quest. It is found by searching upstairs and downstairs in the secondary Elemental Workshop, and the location is random for each player. It can be used, along with the large cog and small cog, to repair the wind tunnel by placing it on the lower-left pin on the east side of the room.
