Involved Areas
 * Upper Jeuno
 * Lower Jeuno
 * Port Jeuno
 * Eldieme Necropolis
 * Castle Zvahl Baileys

Speak to Guslam (Upper Jeuno H-8, Durable Shields), who will tell you to find ‘a pair of old arm guards’ (key item) from a coffer in the Eldieme Necropolis. Tomb Warriors, Tomb Mages, Spriggans, and Haunts all drop the Coffer Key, but I would recommend sticking with the first two. Bringing higher-level Monks along makes the process makes things go fairly fast. The cross-section of M-10 on the second map (the one with four separate sections), where the ‘Hume Bones’ for the Blue Ribbon Quest are located and the surrounding area (watch for Lichs and Dark Stalkers) is a popular camping spot for Tomb Mages and Warriors. After you have your coffer key, you can solo getting the coffer so long as you’re careful and either have a buddy, a White Mage sub of 25+, or a stack or two of Sneak Oils. Everything in Eldieme is aggressive to sound. Zoning in from Beaucedine Glacier and hunting the coffers in that section is recommended. Return the key item to Guslam, who will tell you to speak to Yin Pocanakhu in Tenshodo Headquarters (being a Tenshodo Member is required). Yin is a Mithra standing in the middle of the main room. She will ask you for 1000 gil to give you directions to a toolbox that will not open. Give her the gil, and she will direct you to the ??? outside the Duty Free Shop in Port Jeuno (H-8). After a cut-scene, you will be instructed to retrieve the ‘Shadow Flames’ (key item) from Castle Zvahl Baileys. From the entrance to Baileys, the path is fairly straightforward, follow it until it diverges, and then keep following it west to a gate at F-8. Please note in Castle Zvahl Baileys it is always best to stay as close to the center of the path as possible, as mobs can agro from below and create some rather nasty trains. Clear any Demons in the area, and assign one person to choose a torch and click it. Defeat the NM Bomb Dark Spark (he can explode and do massive area damage, so killing him with the most speed possible is important) and touch the torch again. Make sure everyone in the party knows which torch was originally selected, or Dark Spark will pop again. Once you have the key item ‘Shadow Flames’, return to the ??? outside the Jeuno Duty-Free Shop again to receive your Fighter’s Mufflers.
