Antlion ( Final Fantasy XII ) The Antlion is an Elite Mark from " Final Fantasy XII " . The hunt becomes available upon reaching Mt Bur - Omisace , so if the player wishes to fight it with Larsa in the party , they should return to Rabanastre upon reaching the mountain to accept the hunt , because Larsa will leave the party if the player proceeds further in the story . Antlion can be found in the Site 9 area of the Lhusu Mines . It is also fought in the " International Zodiac Job System " Trial Mode at stage 44 , along with five Killer Mantises . Battle . Before entering Antlion ' s lair , it is best to buff the party . Antlion is surrounded and protected by Killer Mantises ( level 44 ) , and the battle relies more on crowd control rather than depleting Antlion ' s HP . The Antlion will begin with buffs , but the buffs will expire and the Antlion will not cast them on itself again . The player can even hang around nearby until Antlion ' s buffs have expired before engaging it . Black Belt is a good accessory to wear to immunize against Disable . A simple tactic is to lure the mantises one by one , and slowly depleting their quantities before the Antlion notices the party . If not , one can focus on using high - level magicks that hit all targets in range . Antlion itself is weak to Wind - elemental attacks . Another tactic is to use Warp to quickly kill the mantises - Antlion is Warp - immune , but his underlings are not , so a Warp ought to send most ( if not , all ) mantises into the void . The player can have the backup characters use a Quickening chain to get a Concurrence that will wipe out the Killer Mantises . The player can then switch to the main party to finish the battle . Overall , the Mantises can be annoying since they serve as an efficient meat shield , while the Antlion itself is capable of dealing moderate damage . Equipping Wind - elemental weapons works well while battling Antlion , but when around 40 % of its HP is drained , Antlion will use Cannibalize to feast upon one of the Mantises and increase its stats and heal itself . Antlion is capable of using Cannibalize more than once , so one should focus on destroying all the Mantises first before focusing on Antlion itself . After eating one Mantis the Antlion ' s level increases to level 44 , and if it eats another one , its level is boosted to level 52 . One tactic is to use a character equipped with a shield , preferably with Shield Lores learned , and under Decoy status to attract and then block most of the attacks . This tactic works especially well with Disease . The Nihopalaoa + Remedy trick will work on the Antlion and the Disease status stops it from gaining HP from cannibalizing the mantises and stops its HP threshold skills from activating , meaning Antlion won ' t become immune to shield blocks during the battle . An alternate tactic is to clear the area near Antlion ' s lair and summon Chaos , wait until his summoning period is almost over , and enter Antlion ' s lair . Chaos ' s final attack , Tornado ( Wind - elemental ) , should give the party a good start in defeating Antlion and the mantises . Rewards . After the battle , the kids mention of having dropped the key to Site 11 . The Site 11 key can be found near the Fallen Bhujerban in the Phon Coast Hunters ' Camp . The Fomalhaut gun also spawns in a random treasure at the back the room where Antlion spawns , making it one of the first ultimate weapons the player gains access to .
