final fantasy x omega ruins
Game: Final Fantasy X/X-2
Content Type: Gaming Guides


The Omega Ruins is an optional dungeon that you can access any time after gaining after getting control of the Airship. To unlock it, you must search for the coordinates ‘x72, y35’ on the map of the airship. Then, fly to the ‘Omega Ruins’ location. This dungeon has some of the most powerful fiends in the game, as well as two superbosses. This place is also a great spot for grinding AP and farming gil.

Watch out for the Great Malboros in this area. Unlike the ones within Sin, this version of the fiend will ALWAYS ambush your party and immediately use Bad Breath. The best way to counter this is to have a weapon with the ‘First Strike’ passive, so that the character that has it will go before the Great Malboro. Then, you can either use Provoke to stop it from using Bad Breath, or use Flee to avoid the battle altogether.

There’s a hidden minigame in the dungeon that involves many of the chests you will find within. More specifically, you will find four rooms throughout the Omega Ruins that have a group of chests (1 room with 2 chests, 2 room with 3 chests, and 1 room with 4 chests). Each chest in these rooms has a 50/50 chance of containing either an item, or triggering a battle with a Mimic. If you either find a Mimic, or leave the room after opening one of the chests with an item, the rest of the chests in the room will disappear.

There is a progression of items you get as you open chests that contain items in a row. Note that the item progression resets if you get a Mimic or reload your save:

  1. Lv. 4 Key Sphere
  2. Defending Bracer
  3. Turnover
  4. 2 Lv. 3 Key Spheres
  5. Defending Armlet
  6. 2 Friend Spheres
  7. Lv. 4 Key Sphere
  8. Phantom Ring
  9. Cactuar Wizard
  10. Warmonger
  11. 2 Teleport Spheres
  12. 99 Warp Spheres

Getting all of the items from this minigame relies entirely on chance, since there is no way to guarantee you won’t find a Mimic. As there are other ways of getting Warp Spheres, and there is a VERY low chance of getting an item from all 12 chests (specifically, a 1 in 240 chance), you’re better off not worrying about this minigame and just getting the items that you can.

The Save Sphere at the beginning of the ruins is the only one in the entire dungeon. Move forward until you reach a three-way split, and head right to reach the first cluster of chests that’s part of the treasure minigame. Head back to the three-way split and go left now, continuing until you see another split. Head left to find another group of chests, then go back to the split and head north.

When you reach yet another split, take the left path and you will find another cluster of chests. Then, go back to the split and head right. As you go through here, you will notice a glyph on the wall. You can’t do anything with it right now, but keep in mind that it’s here. Eventually, down the path you will find the final cluster of chests. Just north of the chests you will find the Al Bhed Primer Vol. XXVI.

The image is a little dark, but this is the glyph you are looking for

To the left of these chests, you will find a path that leads to a glyph similar to the one you saw before. Touch this glyph, then make your way back to the first glyph (the one we mentioned earlier — it will now be activated), and interact with it. Activating both glyphs will create a small bridge just south of where the first glyph was. At the end of this bridge you will find a chest containing a Teleport Sphere.

Head back to where you saw the fourth cluster of chests, and head right to find a glyph on the floor. Stepping on this one will have it lift you up to the next level. Then, head forward and you will be put into a boss fight.

Ultima Weapon is one of the game’s superbosses. For full details on how to fight it, you can check out our Ultima Weapon guide.

After the battle, you will see a teleporter. As there are no other Save Spheres in the dungeon, it might be a good idea to make your way back to the entrance and save your game before continuing. When you’re ready, step on the teleporter to be taken to the next area.

There will be no random battles in this area. Instead, every time you step on a large circle, you will be forced into a battle (however, you have the option to run from these battles).

Take the left path, and at the end you will find a chest containing a Friend Sphere. Go back and make your way through the right path. When you reach the end, you will see a wall of fog. Walk up to the wall to begin a boss fight.

Omega Weapon is another one of the game’s superbosses. For full details on how to defeat it, you can check out our Omega Weapon guide.

After the battle, you will automatically be taken back to the entrance of the ruins. If you go back to where you fought Omega Weapon, you will find a chest with a Magic Sphere (however, the area leading up to it will now have random battles).
