Adrammelech ( Final Fantasy XII boss ) Adrammelech is a boss in " Final Fantasy XII " . The party fights him in the Zertinan Caverns . To find him , the party must make their way to the Athroza Quicksands . It is fought in the " International Zodiac Job System " version at stage 35 of the Trial Mode along with Skulwyrm x2 . Battle . Adrammelech is the only Esper the player can farm High Arcana from , since the party can flee one screen during the battle , then return and steal again . One does not need to possess the Canopic Jar to make the High Arcanas available . Adrammelech is resistant to all elements but Ice that he is weak to , and is a flying opponent , meaning only ranged weapons and abilities can hit him . As soon as the player steps into the area , Shambling Corpses will emerge out of the ground and will keep on spawning at deeper areas of the cavern . Adrammelech does not have a wide attack range , but his existing skills make him a force to be reckoned with . He has powerful Lightning - type spells , and Thundaja can be deadly . Adrammelech can also use Bleed , which has a high success rate . When his health hits HP Critical , he will use Thundaja regardless of any action taken . If this attack does not KO the party , he will use Perfect Defense , which negates all physical and magickal attacks . Strategy . A party of level 30 + is suggested , though , with Quickenings this boss can be defeated at low levels . Before fighting Adrammelech , one should buff the party , especially with Shell , and equip the characters with ranged weapons with non - elemental ammunition . One can also use ranged Technicks , such as Telekinesis or Gil Toss . Since Adrammelech is Lightning - based , it is advisable to equip Rubber Suits , or Zodiac Escutcheon . It is possible to defeat the Shambling Corpses before Adrammelech notices the party , but it is hard to do if the party is not a considerably high level . A strategy that works well is to equip party members with the gambit " Foe : undead " along with a White Magick spell such as Cura . Another method is to have one character with " Foe : undead " as their primary gambit , one character with long range weapon with " Foe : flying " or " Foe : highest HP " or other gambit that makes them target only Adrammelech , and one healer . The Shambling Corpses can be disabled to render them harmless for the time being . The Shambling Corpses respawn in deeper areas of the cave , so the deeper the place the player fights Adrammelech , the lesser the advantage will be . If one enters the area from the north , Adrammelech will most likely be right on the top . When Adrammelech uses Perfect Defense the party should focus on re - buffing and healing . Having Bubble may help reduce the damage and will it aid in the Sap status ailment caused by the Shambling Corpses . A surefire way of defeating Adrammelech is to use Blizzara or Blizzaga ; this is even more effective should the player have elemental - enhancing equipment ( especially a Glacial Staff ) and Faith status ) . One should make one character the designated healer , as Adrammelech ' s tendency to cast Thundaja and Bleed can quickly reduce a party ' s HP . There ' s a way to make the most out of Quickenings : the player should have the first group use Quickenings for maximum damage ; afterward remove one character who is out of MP , and add a reserve character with full MP to the party , and unleash a new Quickening chain . By repeating this procedure Adrammelech will soon fall . This strategy allows the party to defeat him even at low levels .
