Enemy list
Chest list
From Lufenia, fly into the desert on the northeastern continent. Park your airship east of the desert's center.
Mirage Tower
The tower is 3 floors with 18 treasure chests; the Flying Fortress above has another 34. Stock up before attempting this — you can Exit anytime, but both dungeons are long. Fire and Ice magic works well here. Check the bestiary for enemy weaknesses.
1F. Walk through the door as soon as you enter. Walk straight through the first opening and follow it around. There'll be 8 treasure chests in this area; collect them all. After you've collected the most western one, walk around the wall and head south. You'll be back to where you walked through that first door except this time, take the door on the left and walk up the stairs to 2F.
2F. Circle around the entire room and you'll find a gap in the wall eventually. Walk through it and then walk through the second gap and continue heading south until you reach the room. There will be 10 chests to collect. Exit the room and go directly north around the room. Ignore the robot (sorry robot) and walk upstairs to 3F.
3F. Walk south, go into the room and defeat the Blue Dragon blocking your path.
Proceed to the red teleporter in the middle of the room. Use the Warp Cube to reach the Flying Fortress.
Flying Fortress
The Flying Fortress is five floors with 34 chests. Unlike Sunken Shrine, there's no backtracking between floors. Just explore every room, grab treasure, and fill your bestiary.
1F.

4F. This floor uses square holes to navigate. Walk two squares north, then two squares west to reach the teleporter to the final floor.
5F. Walk directly north across the long bridge to reach Tiamat and the Wind Crystal. There's a rare superboss on this bridge (Warmech) you can read more about below if you wish to fight it before Tiamat. Heal up and restore MP with Ether before the fight.
Warmech
On the bridge (5F), there's a 4.7% chance to encounter Warmech, a superboss stronger than Tiamat with 2,000 HP. He's needed for the Field Research - Professional trophy but entirely optional. But be warned: some players report walking the bridge for hours before he shows up.
If you want to fight, cast NulBlaze (Nuke is fire-based), stack Invisira, NulAll, and Protera, then go all-out with Haste and physical attacks. Lightning magic is the only element Warmech doesn't resist.
Tiamat
Tiamat is the Fiend of Wind and the last of the four elemental bosses.
Defeat Tiamat and the Wind Crystal is restored. All four crystals now shine. Use the portal to exit.
Return to Mt. Duergar
Take your airship and fly to Mt. Duergar on the western continent. We're going to use that Adamantite we collected earlier to forge one of the strongest swords in the game.
Find Smyth the blacksmith in the northern room. Show him the Adamantite and he forges Excalibur, one of the strongest swords in the game. Equip it on your Knight immediately.
With all four crystals restored and Excalibur in hand, it's time to tackle the final dungeon. Stock up on all items and make sure you've got all the best equipment and spells. Your next destination is the Chaos Shrine, where your journey began.
