Ashe: With that much nethicite in one's grasp...

Fran: You could destroy all of Ivalice, if you wished it.

Ashe and Fran talking about the Great Crystal

The Great Crystal is a location in the land of Ivalice in Final Fantasy XII. It is a large crystal located in the deepest reaches of the Giruvegan. The player won't get a true map of the area, but a sketch of the outside of the crystal, and an indication showing an approximation of where they are from the outside (near the bottom, as opposed to near the top).

The core of the crystal is a great orb of magicite, constantly spewing Mist. Though the party speculates that it might be nethicite, its exact nature is unclear.

While its purpose is never revealed, it may be assumed the Great Crystal is the Occuria's deposit of nethicite, or perhaps the source of magicite and Mist. Whatever the case, it acts as a deadly gateway to the Occurian dwelling, filled with powerful monsters and a twisting maze. Also sealed within are the fearsome prisoners, the Espers, Ultima and Shemhazai.

Story

Spoiler warning: Plot and/or ending details follow. (Skip section)

By this path and no other, reach ye the Round of the Undying, walk of the Chosen.

Empyrean Way Stone

Princess Ashe and her comrades come to Great Crystal in their hunt for Dr. Cid who claimed he is taking the Empire's pieces of deifacted nethicite with him to Giruvegan. As the party arrives on the gates of the ancient city they see Cid nowhere in sight, and prompted by an apparition of her late husband, Lord Rasler, Ashe ventures deeper into the ruins where the party finds Great Crystal at its core.

Ashe receives the Treaty-Blade.

Inside the crystal the party comes across a final Way Stone that takes Ashe to the domain of the Occuria where she speaks with Gerun, the spokesperson of the Occuria, and notes the throne of Venat is empty. Gerun claims Venat is a heretic and has given the secrets of nethicite to the hands of the Empire.

To undo the harm Venat has inflicted on the Occuria's goal, Gerun entrusts Ashe with the Treaty-Blade and instructs her to find her way to the Sun-Cryst to cut a piece of deifacted nethicite with it and use it to lay waste onto the Empire. Ashe hesitates, but upon seeing the apparition of Rasler clutching the blade she follows suit, and is transported back to the Great Crystal where she is greeted by her friends, who, although not able to see the Occuria, heard their voice. Ashe takes the Treaty-Blade and, when Balthier realises Dr. Cid was never coming to Giruvegan, she decides to look for the Sun-Cryst.

Spoilers end here.

Location

Not actually located on the world map, the Great Crystal is found in the Ancient City of Giruvegan. The player has to walk down to the deepest reaches of the Gate of Fire and find a waystone, which grants access to the area. The Great Crystal links the Gate of Fire at Giruvegan with the floating Gate of Wind and is the only way the Occuria and Shemhazai can be accessed.

Navigation

The Great Crystal is difficult to navigate due to there not being a full map. The player may use the unique naming system for the crystal's areas (see below) to navigate the crystal. There is also a full map in the gallery at the bottom of this page.

The Great Crystal is divided in two halves: the section that is part of the storyline and rather straightforward, and the optional section that opens up only after the story in the place has been completed.

Complicating navigation are the zodiac gates that block some of the paths between areas. Each gate has a stone that deactivates it, indicated by the shared name (e.g. the Pisces Gate Stone deactivates Gate Pisces). In the storyline area, they behave much like those in Giruvegan—once activated the corresponding gate is removed. However, in the optional area, each stone can open one of two gates (e.g. the Leo Gate Stone can open either Gate Leo I or Gate Leo II).

Crucially, only one of the pair can be open at any one time. When the stone is activated, both gates are closed and a countdown timer activates. The player has to reach whichever gate requires opening, and activate it within the time limit to remove the gate. The time varies between stones, and is sufficient to reach either gate if the player goes directly there without engaging in too much combat. The state of the gates is retained for future visits.

Location names

The map of the Great Crystal hides the player's location to add to the mystery of the area. The names of the area of the Great Crystal may sound like it came from out of a Sanskrit dictionary, but it is actually contractions and bastardization of English words and some scientific terms, which help to indicate location:

Name	Meaning	Purpose
A	Up	A, Dha, Si, Ra, and Vikaari are used to indicate where a teleporter will take the party. "A Vikaari" means move up a layer and "Dha Vikaari" means to move down a layer.
Dha	Down
Vikaari	Shift
Si	Shift
Ra	Shift
Peak	Peak	Crystal Peak is obviously the top. Kanbhru, Oldobii, Sirhru, Dhebon, Kabonii, Bhrum, Trahk, and Jula are all named after prehistoric periods, with the oldest coming highest inside the Great Crystal. Crystal Core is obviously the Central Core.

Jilaam	Xylem
Phullam	Phloem
Prama	Ground	Crystal Ground is where the Waystone links the player with Giruvegan.
Sthaana	Set	Sthaana indicates a location with a Gate switch.
Note: The "Sthaana" Gate switches are named after the corresponding Zodiac gates.

Treasures

File:Holy-Lance-Treasure.jpg

The party finds Holy Lance.

The storyline area has three treasures. They always spawn, will never respawn, and never contain gil. The first treasure is in the Kabonii Jilaam Pratii'vaa area, right the next area from the Waystone VIII where the player starts. Without the Diamond Armlet the treasure is either Elixir or Black Mask. With the Diamond Armlet the treasure is 90% Black Mask, 10% Knot of Rust.

The next treasure is past Waystone VI. It can be found if the player takes the middle path from Waystone VI, to an area called Bhrum Pis Avaa. Without the Diamond Armlet it is either Knot of Rust or White Robes. With the Diamond Armlet it is always a Knot of Rust.

The final treasure of the mandatory section of the Great Crystal is past Waystone IV, in the area right before the Aries switch, called Trahk Jilaam Praa'dii. Without the Diamond Armlet the treasure is either Knot of Rust or Holy Lance. With the Diamond Armlet the treasure is always Knot of Rust.

The treasures of the optional part of the Crystal are labeled in the map below (in the gallery).

The treasures in the original release are:

1. Zodiac Escutcheon or Brave Suit when Diamond Armlet is not equipped. With the Diamond Armlet the treasure is always the Zodiac Escutcheon. The treasure has 20% spawn rate and will never respawn once claimed.
2. 2 gil or Knot of Rust or Stoneblade without the Diamond Armlet. With the Diamond Armlet the treasure is 5000 gil or Knot of Rust (common) or Glimmering Robes (rare). The treasure has 80% chance of being gil.
3. 2 gil or Knot of Rust or Maximillian without the Diamond Armlet. With the Diamond Armlet the treasure is 5000 gil or Knot of Rust (common) or Demon Shield (rare). The treasure is 85% gil.
4. 2 gil or Knot of Rust or Mirage Vest without the Diamond Armlet. With the Diamond Armlet the treasure is 5000 gil or Knot of Rust (common) or Gungnir (rare). The treasure is 75% gil.
5. This area actually has two treasures. The other has only 20% chance to spawn, but it is always the Excalibur. After being claimed the treasure will never respawn. The other treasure is either 2 gil or Knot of Rust or Sage's Ring without the Diamond Armlet, and 5000 gil or Knot of Rust (common) or Renewing Morion (rare) with the Diamond Armlet equipped. The treasure is 80% gil.
6. 2 gil or Knot of Rust or Power Armlet without the Diamond Armlet, or 5000 gil or Knot of Rust (common) or Golden Skullcap (rare) with the Diamond Armlet equipped. The treasure is 70% gil.

Quests

Rare Game

See also: Rare Game

Evil Spirit has a 5% chance of appearing instead of a Forbidden.

Larva Eater

The Larva Eater is one of the toughest enemies to spawn, mainly because of the criteria required to spawn it.

The spawn method based on the The Zodiac Age Ultimania explains that it appears after the player has killed 256 enemies since their last travel with a Waystone, and will only spawn at Waystones III-X, XIII-XVII and XX, and subsequently after the next 30 to 255 kills. Kills in this case include any enemies that Self-Destruct such as Mom Bombs, and killing enemies that spawn from using Divide such as Necrophobes. Chains are not required to be maintained. As with the Reaper, leaving the Great Crystal or reloading the save file will reset the kill count.

Crystal Knight

To find the Crystal Knight the player must have spoken to the "Huntmaster" in Phon Coast and defeated Thalassinon, which will trigger the start of the Rare Game quest. To spawn the Crystal Knight, the player must start at Way Stone XX and run a clockwise loop to the Sagittarius Gate Switch and back. The Crystal Knight appears on the platform with two Forbiddens. Once it has been slain, the Crystal Knight can never be hunted again.

To reach the Sagittarius Gate Switch, from the first area of the Great Crystal the player should move one area to find and open the Scorpio Gate Switch, then move back to the previous area and take the exit to the left of the path to the Scorpio Gate Switch. This takes them to Waystone IX, which teleports the party to Waystone X.

Finding Ultima

Ultima.

The Esper Ultima can be fought after receiving the Treaty-Blade. The player must return to Waystone VIII, which is the waystone that allows access to Great Crystal from Giruvegan. From the waystone, there are three paths: one goes up, one goes down and another one is sealed by Gate Scorpio. The player must follow the path going up and unseal Gate Scorpio on the following platform, then return to Waystone VIII and head through Gate Scorpio to Waystone IX, which can be used to teleport to Waystone X.

From Waystone X the player reaches Waystone XX. On this platform there are two paths sealed by Gate Sagittarius (Gates I and II), plus another three paths: one going down, two leading up, and the last path is the one the player came in on. From the path they arrived from, the player should head directly across the platform toward the only other path heading down. Eventually they will come to a switch for Gate Sagittarius.

After unsealing the gate there will be a time limit of 71.00 seconds and the player must hurry back to Waystone XX. The player can either go back the way they came, or head up to the next platform, and then take the only path leading down, which will lead back to Waystone XX. (Taking this path is the spawn condition for the Crystal Knight, who will appear next to the Sagittarius gates if the player has started the Phon Coast Hunt Club sidequest.) After reaching Waystone XX the player must open Sagittarius Gate II.

Descending from Sagittarius Gate II leads to Waystone XII, which teleports to Waystone XIV. On this platform there are two paths, one leading up and the other leading down. The player must head up to the Gate Leo switch, then return to the previous platform, as again there will be a time limit, this time of 215.00 seconds. From the platform the player should take the path going down and then take the only possible path on the next platform. On the third platform there are two paths, one leading to Gate Leo II and the other to an Excalibur treasure, which isn't accessible yet.

After passing through Leo II there are two more paths and Gate Gemini. The player can take either path, both leading to Waystone XV that teleports to Waystone XVI.

On Waystone XVI the player must follow the middle path to the switch for Gate Libra (this place will be revisited). The player must push the switch and return to platform XVI. There will be a time limit of 71.00 seconds. Facing Waystone XVI, the player should take the right path upward and on the next platform unseal Gate Libra I. The player should continue to head up from the newly opened gate to reach a platform with three paths; the player should head left and take the only path leading up.

After pushing the switch for Gate Capricorn the player should return to platform XVI (with a time limit of 180.00 seconds). On platform XVI they should take the only path heading down to Gate Capricorn I and the switch for Gate Virgo. After touching the switch the player should quickly return to platform XVI (with a time limit of 108.00 seconds), and on platform XVI follow the middle path, which leads back to the Libra switch; from there the player should follow the path down to two Gates, Capricorn II and Virgo II on the next platform, unseal Gate Virgo II and cross it.

In the next section, from where the player entered, they should take the right path leading up to Waystone XVII that teleports to Waystone XVIII. The path will lead to a Save Crystal. From the Save Crystal there are three paths: the one heading down leads the Aquarius Switch, and the opposite leads to Waystone XIX, which will warp back to Waystone XX. Ultima is sealed down the path in the middle.

Finding Omega Mark XII

Omega Mark XII is available to fight once the hunt for Yiazmat has been accepted. The player party can enter Omega's chamber 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 (see above) 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 at. 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.

If the player instead wants to open the path to Omega Mark XII right away, they should 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.

The player may want to save their game 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.
