Ultima ( Final Fantasy XII boss ) Ultima is an optional boss in " Final Fantasy XII " located in the lowest reaches of the Great Crystal in Giruvegan . Defeating Ultima unlocks her sprite in the Sky Pirate ' s Den and earns the player the title of Fell Angel , and adds her license on the License Board so the player can recruit her as an Esper . Finding Ultima . 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 other 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 . Battle . The party will receive damage every time they attack her . Ultima uses Redemption and a normal attack that has a chance to inflict Sap . Her special attack is Holyja . Ultima is weak against dark and blindness . If afflicted with Blind Ultima will cast Blindna on herself . At the start Ultima will cast Holyja after twelve attacks , which includes standard attacks and Redemption . Like all other Espers , Ultima ' s special move has a chance of inflicting a negative status on the party ; Holyja inflicts Reverse , upon which Ultima will cast Renew on the Reversed characters leaving them at 1 HP . After her HP has been drained to 80 % , Ultima will cast Holyja , regardless of the number of times she attacked . When Ultima ' s HP drops down to around 70 % , a magick field will fall , causing the following debilitations in this order : HP decrease , MP decrease , Attack Command seal , Magick Command Seal , Technick Command Seal , Item Command Seal , Increase / Lag weapon attacks ' Charge Time . The Magick seal will continue to cycle until Ultima is defeated . When Ultima ' s HP drops to 70 % , she uses Holyja after seven attacks instead of twelve . She also casts Reflectga on the party from time to time and cast Curaja on the reflected party members , effectively killing any party member who has Reverse on their status ( as Ultima ' s magick is piercing , thus ignoring Reflect ) . Like other Espers ' , Ultima ' s stats will increase as her HP depletes . When Ultima ' s HP drops to 30 % , she uses Holyja after only three attacks , and Holyja becomes more powerful . Strategy . Before fighting Ultima , it is recommended for the main party members to be at least level 55 or above ; level 40 or above for back - up characters . Aside from that , it is helpful to have three White Masks , or a Sage ' s Ring , to absorb Ultima ' s Holyja attack . The player should stock Ethers and curative items before the fight . Bubble Belts , Rings of Renewal , and Opal Rings are useful for additional advantages . All holy - elemental weapons , such as Excalibur or Holy Lance , should be removed . As Ultima is weak against dark , the Darkga spell and Dark Shot for a gun exploit this weakness , as well as ninja swords . One can unequip White Masks or Sage ' s Ring to lure Ultima to use Redemption , then immediately switch back to White Masks or Sage ' s Ring to absorb her attacks . Should the party be inflicted with Reverse from Ultima ' s special attack , one should immediately cast Dispelga / Dispel / Esunaga / Esuna , or Ultima will cast Renew on the Reversed party members . It is recommended to equip Ring Of Renewal ( Auto Regen ) during the magic seal , and simply cure with X - Potions , if there is a healthy stock . When Ultima begins casting Reflectga on the party a member must equip the Opal Ring if he / she wants to cast curative magic under Reflect . Although , this may be an opportunity time to cast Darkga , resulting in the maximum of twelve hits on Ultima ( this is if the player has a guest and all three controllable party members cast the spell ) . When Ultima begins casting Reflectga on the party , if the timing is right , after dispelling the party from Reflect , Ultima might cast Curaja on the characters , healing 3000 and above HP . If the player does not dispel Reflect in time , Ultima ' s Curaja will Kill any party member afflicted with Reverse . There is a way to avoid Ultima casting either Renew or Curaja by keeping one party member unequipped with any kind of equipment that absorbs Holy damage . When Ultima ' s stats increase when she is in low health , the party will benefit from Haste , Bubble , Protect , and Shell , as her attacks are fast and powerful . A good tactic to defeat Ultima is to equip everyone with Yagyu Darkblades and have two members in HP Critical to boost attack ( if the characters have obtained the Low - HP ATK + Augment for 70 LP ) and berserk them . The remaining member should be the decoy , and focus on healing everyone . The party should equip Sage ' s Rings / White Masks when Ultima casts Holyja , and have the tanks cast Infuse to get back to HP Critical , when Berserk wears off . When Ultima stops the party from using physical attacks , the player should switch the tanks for mages , and continuously use Darkga . A cheap way to win this battle is to exploit Ultima ' s weakness to Blind . The player can stock 99 Eye Drops , equip a character with a Nihopalaoa and keep throwing Eye Drops on Ultima to inflict Blind . Ultima will immediately cast Blindna , effectively trapping it in a loop while the other two characters can attack it . However , Ultima may still cast Holyja .
