In the Zodiac versions, Omega Weapon is also fought on the Trial Mode stage 99.
Clan Primer Edit
An ancient weapon of war, traveling the rifts between dimensions. Its body is set with machineries and weaponry of a far higher order than anything made today. Though it is a construct, it was built with the ability to grow, and so it has evolved like a living creature.
It generates the energy it needs to live by filtering and condensing Mist from the air.
Finding Omega Mark XII Edit
Omega is located in the Great Crystal at Giruvegan and is only available to fight once the hunt for Yiazmat has been accepted. The player party can enter Omega's chamber in the Crystal beforehand, but it will be in a dormant state and unresponsive, resembling a giant treasure chest like the Mimics in other dungeons.
The player must have made it to the area before Ultima, and have Way Stone XX activated. Using Way Stone XX the player can teleport to Dha Vikaari Dhebon Ra, then cross Kanbhru Pis and activate the Aquarius Gate Stone in Sthaana Aquarius. The player can now go to Dha Vikaari Uldobi and use Way Stone XVIII to teleport back to A Vikaari Kanbhru.
Once there, the player should head to Uldobi Jilaam Avaa, and take the right path to Uldobi Jilaam Praa'vaa. If Gate Libra 2 is blocking the way the player can either take the left path and hit the Libra Gate Stone, then unlock Gate Libra, backtrack to the Aquarius Gate Stone and come back, or go the long way by moving left through Sthaana Libra, turning right and crossing Dha Vikaari Sirhru, turning right again and crossing Uldobi Jilaam Praa'dii, heading straight to Uldobi Jilaam Praa and on to Uldobi Phullam Praa'vaa back to Aquarius Gate 1. The player should touch it but not enter.
If Gate Libra 2 is unlocked when the player first gets there, they should head straight to Uldobi Jilaam Praa and turn right to enter Uldobi Phullam Praa'vaa, touch Gate Aquarius 1, but not go further.
The player should return to Uldobi Jilaam Praa and take the path to the right. At Sthaana Capricorn, the player should touch the Gate Capricorn Stone before returning to Uldobi Jilaam Praa. The player should take the right path to reenter Uldobi Jilaam Praa'dii and take the only path across to return to Dha Vikaari Sirhru, where they should approach Way Stone XVI before entering the first path to the left to return to Sthaana Libra. The player should head right and in Uldobi Jilaam Pratii'vaa, touch Gate Capricorn II on the right but not go through; instead, the player should return to Gate Aquarius I and enter the other path leading to Sthaana Taurus. To get there, the player should take the Left at Sthaana Libra, right at Dha Vikaari Sirhru, straight on at Uldobi Jilaam Praa'dii, straight on at Uldobi Jilaam Praa and left at Uldobi Phullam Praa'vaa.
After activating the Taurus Gate Stone the player can return all the way back to Uldobi Jilaam Pratii'vaa and enter the right path where Gate Capricorn II was. The path to the left will lead to Gate Carpricorn II and activating it will allow access to the right in the next area that will possibly have a Brave Suit or the Zodiac Escutcheon, the best shield in the game. Doing this however, the player will have to backtrack all the way to the Capricorn Gate Stone and re-activate it.
In order to open the path to Omega Mark XII right away, enter the path directly ahead in Uldobi Jilaam Pratii and activate Gate Capricorn I in Uldobi Phullam Pratii'dii, take the right path after activating the Gate Capricorn to find Way Stone XXI on the platform of Dha Vikaari Sirhru Si. Way Stone XXI will take the party to A Vikaari Uldobi Si, which is one platform away from the Way Stone XXIII that will teleport the party to the platform right before Omega Mark XII.
It is advisable to save before fighting the boss. To get to the closest save crystal, the player should go left at Uldobi Phullam Pratii'dii, straight on at Uldobi Jilaam Pratii, left at Uldobi Jilaam Pratii'vaa, right at Sthaana Libra, right at Uldobi Jilaam Praa'vaa, left at Uldobi Jilaam Avaa, teleport at Way Stone XVII in A Vikaari Kanbhru, head straight on at Dha Vikaari Uldobi to get back at the blue save crystal in Kanbhru Pis.
To get back to Omega Mark XII from the save crystal, the player can teleport at Way Stone XVIII in Dha Vikaari Uldobi, go right at Uldobi Jilaam Avaa, left at Uldobi Jilaam Praa'vaa, left at Sthaana Libra, right at Uldobi Jilaam Pratt'vaa, straight at Uldobi Jilaam Pratii, right at Uldobi Phullam Pratii'dii, take the Way Stone XXI in Dha Vikaari Sirhru Si to A Vikaari Uldobi Si, then walk down the path to Dha Vikaari Dhebon Si and use Way Stone XXIII. The party will end up in A Vikaari Sirhru Si, from where they can go down one more platform to Dhebon Jilaam Avaa and fight Omega Mark XII.
Omega is a tough opponent and will continuously use a laser beam that kills a character in two hits, even at level 99.
Omega will always attack the nearest target and is one of the few enemies that cannot detect players who are vanished.
A viable option at any level is to get three decoy characters under Stop and Reverse, a primary mage, a vanished character, and the character who controls Zodiark. Omega is one of the few enemies in the game that cannot detect players who are vanished, so a vanished character should never be targeted as long as they don't target Omega either.
First the player must get the Zodiark character under Reverse, and approach Omega on the platform, then summon Zodiark, who will use Final Eclipse. After that, the player can dump one of the decoys on the platform (leaving the Zodiark character KO'd) and put in the vanished character, who will try to sneak away and revive the Zodiark character, also putting them under Reverse.
The player should then remove all characters from play and go to the stopped decoy who keeps Omega busy and put in the character who controls Zodiark and use Final Eclipse again. If Stop runs out, the player can dump in another decoy, revive the fallen one and put them under Stop and Reverse again. The idea is to repeat this action, using Final Eclipse 20-30 times or so, until Omega falls. The key is keeping the decoy on the platform with Omega, so it stays busy and doesn't restore itself.
Another simpler tactic is to, with Bubble Belts equipped, use the following gambits in this order: (1) Self = Reverse; (2) Any Ally = Arise; and (3) Attack nearest target. Once in a while, the party should cast Hastega after a party member has cast Reverse on him/herself. Omega always attacks the nearest target, so the player can keep one mage/long range type character out of its range to revive fallen allies.
The Final Fantasy XII Scenario Ultimania reveals that the Mythril Sword, an item not obtainable through shops, loots, or treasures, can be obtained from defeating Omega. Although the odds are astronomically low, it is possible it might even drop two Mythril Swords. The player should raise the chain level to its highest just before attacking Omega if they wish a chance to receive one. Unlike other optional bosses, Clan Centurio doesn't give a reward for defeating Omega.
Ancient warmech Edit
According to the Clan Primer entry, Omega Mk. XII is a construct of machine and weaponry that was created to battle a great Wyrm, possibly the Hell Wyrm or Yiazmat. This could also be a reference to Shinryu, dragon associated with Omega in Final Fantasy V.
Omega was given the ability to grow and evolve. It was left in the Great Crystal and allowed to grow on its own, using the Mist as an energy source. The story from the Urutan-Yensa bestiary entry seems to tell of the creation of Omega Mark XII, and implies that the creator lost track of it after its tracking devices were destroyed in a battle of some sort.
Version differences Edit
In the Japanese version, Omega has a little more than 10 million HP, making him second only to Yiazmat. For the North American and PAL versions, its HP was reduced to a mere 1 million, less than the Hell Wyrm and even a couple of the higher Marks.
The North American and PAL versions also added the Berserk status effect onto Omega's attack. Whatever the reasons for these changes, Omega is still one of the toughest battles, being the only enemy at Level 99 with the highest strength, defense and magic power.
"Omega" is a reference to Omega Mark's heritage of the Omega Weapon superboss from earlier Final Fantasy installments. "Mark" in his name probably does not bear influence of the hunt marks of the many hunt clans in Ivalice; it is more likely it is "Mark XII", describing it as the 12th model of Omega Weapon, after a series of modifications to the original.
This naming convention was first used in Final Fantasy V Advance, with the superboss Omega Mk.II. The "XII" part of the boss's name is an allusion to the number twelve, the game's number in the Final Fantasy series.
- Upon defeat, Omega Mark's head falls off upon the Warmech's malfunction. Its decapitated remains, as seen in a short sequence, resemble the traditional Omega Weapon's design even more.
- Much like Gilgamesh, Omega Mark XII is said to be traveling the rifts between dimensions. This could hint that this is the same Omega encountered in Final Fantasy V, who was trapped in the same Interdimensional Rift as Gilgamesh.
- Omega Mark XII was perhaps designed to defeat Yiazmat, as it only "activates" when the hunt for the great wyrm is accepted.
- The story the player can obtain by completing the Urutan-Yensa bestiary makes a reference to Omega, since the author of these pages states at the end that he hopes his Mark XII finds a place "rich in Mist", which is one of the characteristics of the Great Crystal inside Giruvegan.
Omega (capital: Ω, lowercase: ω; Greek Ωμέγα) is the twenty-fourth and last letter of the Greek alphabet. It is synonymous with a set's end or limit.
