Omega Ruins

Omega Ruins.

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 any other location 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.


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

FFX Omega Ruins

Treasure chests in Omega Ruins, with the final volume of the Al Bhed Primers near the wall.

The treasures are randomly either a treasure or a Mimic. If the treasure is a Mimic, the nearby chests disappear. If one opens a chest but leaves the chest group, the other chests will disappear even if the mimic did not appear. The idea is to avoid a Mimic in all four groups to earn 99 Warp Spheres.

Using the diagram it is recommended to get the Teleport Sphere first by activating the glyphs, then proceed to opening chests, the larger groups first, eventually making to the fourth and two-chested group. Should one pick wrongly along the way and encounter a Mimic, it is recommended to do a quick reset, reload the last save and try again. The first group is the hardest as one needs to open three chests. Trial and error and patience is needed. It is recommended to save after each group is complete, though loading back a save game resets to the first item in the list.
