Adamantoise ( Final Fantasy XIII ) The Adamantoise is a powerful enemy on the Archylte Steppe of Gran Pulse in " Final Fantasy XIII " . During the first exploration of Gran Pulse , it is best to avoid them , as they will take the team out in one stomp . It is recommended to return after completing the story to battle them , when the party ' s HP is around 15 , 000 and Strength over 1 , 500 . An Adamantoise also appears on the Leviathan Plaza in Edenhall . To respawn this one , the player can walk up to the sliding fal ' Cie door and return ; going through will cause the soldiers and Humbaba to respawn alongside the Adamantoise . Battle . Adamantoise is immune against " Preemptive Strike " , even with Deceptisol . Destroying the forelegs ( Left Foreleg and Right Foreleg ) will make the Adamantoise fall down . It is unable to attack in this state , but it will recover ( stand up again ) after roughly one minute along with regenerating both legs . The legs are always disabled when an Eidolon is summoned and while the summon is out , the timer for when the Adamantoise can stand back up is paused . When fallen , the Adamantoise becomes susceptible to debuffs ; in its upright state it is only vulnerable to Slow . It uses Earth attacks , Stomp and Quake , which are powerful and hit all ground - based targets . After the sixth Stomp , Adamantoise will always use Quake . Strategy . The Death strategy . If Vanille has learned Death for her Saboteur role , it is possible to defeat the Adamantoise with it , but the chances of successfully landing instant death are low ( 1 % ) . Death ' s success rate can be improved by : Because Death is not classified as a debuffing spell , its chances to inflict instant death cannot be boosted by equipping Vanille with Belladonna or Malboro Wands , nor can its success rate be improved with Faith or high chain bonus . Faith and Haste are still good buffs for Vanille . Haste allows her to cast Death at a faster pace , while Faith boosts her Magic stat , allowing Death to deal more damage when it doesn ' t result in instant death . This technique is helpful for characters with stats too low to fell the Adamantoise otherwise . A good approach is to have Vanille , Fang and Hope , with Vanille as the leader , and to use the Espionage paradigm ( SAB / SAB / SYN ) with Hope as the Synergist . The team should have at least three TP bars full before entering the battle . At the start of battle , Vanille should instantly summon Hecatoncheir to disable the Adamantoise ' s legs . Hecatoncheir will stop Adamantoise from getting up , so Vanille should use Auto - Battle until three debuffs are inflicted , then use Death until Hecatoncheir leaves , or the Adamantoise dies . When Hecatoncheir leaves , Hope should cast Haste , Bravery , Faith , and Veil , while Fang casts Slow , Curse and Fog . If Hope has advanced in the Saboteur role at all , the player can shift to SAB / SAB / SAB to boost Vanille ' s chances at landing Death as soon as the party is buffed . Vanille must keep casting Death until the Adamantoise dies . Vanille can be equipped with Sprint Shoes and a Collector ' s Catalog as well as two Whistlewind Scarves to add Haste and the synthesized ability ATB Rate + 15 % . Without Death . Adamantoises are best tackled when the characters have at least Tier 2 weapons and have mastered their assigned jobs at the Crystarium . Each character should be equipped with a fully upgraded Gaian Ring , Entite Ring , or Physical resistance accessories . Fang should be the party leader and will need a Genji Glove equipped to break the damage limit . The party should start the battle with either : SYN / SYN / SYN , with Fang casting Bravera and Faithra ( manually ) to the team , while the others cast things like Haste and Protect ; or SAB / SAB / SYN , if the party wishes to have access to debuffs ( assuming they are using all of the below and MED / MED / MED for healing ) . After the buffs are in place , the party should switch to RAV / RAV / RAV and stagger one of the legs ( debuffs are not necessary due to Highwind ignoring them during damage calculation ) . Initially , until both legs are taken out , the only buffs each character needs are Haste and Protect / Protectra . As soon as the leg staggers the party should switch to COM / MED / MED and use Highwind on the staggered leg to kill it while the others heal , and repeat the same to the other leg to make the Adamantoise topple ( with appropriate Strength , Highwind will always kill a leg at 600 % chain bonus ) . Once it has fallen , the party can re - cast Bravera and Faithra because they run out fast , then debuff and stagger the fallen Adamantoise . This can be achieved with SYN / SAB / SAB . One should manually cast Bravera / Haste on Fang , and Haste and either Faithra or Bravera on the other two characters . At least Deprotect , Deshell and Slow are useful . Slow is the only debuff that still remains if Adamantoise recovers its legs . The party should aim to stagger both legs by the sixth Stomp , as after this the creature will cast Quake which is very powerful . After the chain bonus is somewhere around 800 % , the party should switch to COM / COM / COM to deal damage , and use Highwind as Adamantoise is recovering from stagger . If it doesn ' t die yet , the party should go back to SYN / SYN / SYN to re - buff and start again by disabling the legs . When the Adamantoise is down to around 1 . 5 million HP , with the Genji Glove equipped on Fang and sufficient Strength , Bravera and stagger gauge exceeding 900 % , Highwind should finish it off . If the Stomp is doing too much damage the party can switch to SEN / SEN / SEN as the Adamantoise is lifting its leg . Spoils . Adamantoise ' s common drop with 25 % chance is the Platinum Ingot , worth 150 , 000 gil . The rare drop is the Trapezohedron , which costs 2 , 000 , 000 gil at R & D Depot . Trapezohedron is required to upgrade Tier 2 weapons into their ultimate forms ( Tier 3 ) . The party can equip the Collector ' s Catalog to increase the drop chance for Ingots and the Connoisseur Catalog to increase the drop rate of Trapezohedrons . Contrary to popular belief , both can be equipped the same time ( although it doesn ' t increase the drop rate of Trapezohedrons , but lets the player get more Platinum Ingots at the same time ) . Getting a 5 star rating gives the best chance of rare drops . Killing an Adamantoise rewards the party with 40 , 000 CP with the possibility to double it for 80 , 000 with the Growth Egg , making Adamantoises one of the best monsters for obtaining CP .
