As you enter, head to the right and get the Gizamaluke's Bell (1) from the Burmecian soldier. Use the bell to open the door and continue.

Zorn and Thorn will send 2 Type A black mages to attack. After that, pass under the bridge and attack the wandering Type A black mages to get another Gizamaluke's Bell (2). Go up the steps and open the left door. Follow the wall around, pick up a Bronze Vest and then talk to the defeated Burmecian soldier to get your next Gizamaluke's Bell (1). Go back down the stairs and open the door to the far right.

As you traverse the stairs, pick up a Mythril Gloves and a Magus Hat. Give the moogle your Kupo Nut to get the him out of the big bell and then pick up another Gizamaluke's Bell (2) from the treasure chest. Use the bell to open the right-hand door to find Mogmi and Moguta. Talk to Moguta and tell him you like Kupo nuts. As you go back out, Moguta will give you the Holy Bell.

Go back out and use the bell to open the other door. As soon as you enter the next room, you must fight Gizamaluke.
