The Omega Ruins (オメガ遺跡, Omega Iseki^?) is a large dungeon located within a small group of islands to the east of Spira's main continent in Final Fantasy X. Rather maze-like, unlike many of the other locations in the game, the cave must be mapped by the player. Navigating the dark passages, Tidus and his friends will encounter some of the toughest fiends in the game, including the Master Tonberry and Great Malboro, while also coming across chests, which yield some handy (albeit random) treasures.

At the end of the cave, two deadly bosses await the party's arrival.

A traitor to Yevon, Omega was banished to these ruins, and during the long years he was imprisoned, his hatred grew and turned him into the fiendish Omega Weapon. His hatred for Yevon was so strong, he also spawned a lesser Weapon: Ultima.

CoordinatesEdit

To be unlocked on the Airship Map, the coordinates 69-75x and 33-38y have to be found using the Search Function.

TreasuresEdit

The treasures are randomly either a treasure or a monster. If the treasure is a monster-in-a-box, the nearby chests disappear. The outcome of the chests is always random, but if the player manages to open all chests, they get 99 Warp Spheres. Because the first treasure is always a L4 Key Sphere, an easy way to harvest these rare items is to go back out after having a go at the first set of chests, as the chests will reset whenever the player leaves and re-enters.

The treasures contain the following items:

1. L4 Key Sphere
2. Defending Bracer
3. Turnover
4. 3x L3 Key Sphere
5. Defending Armlet
6. 2x Friend Sphere
7. L4 Key Sphere
8. Phantom Ring
9. Cactuar Wizard
10. Warmonger
11. 2x Warp Sphere
12. 99x Warp Sphere
13. The last Treasure Chest isn't available on International Versions.
