Geryon Geryon is a superboss in the 3D remake of " Final Fantasy IV " in New Game + mode . He is known as the " Malice of the Four Fiends " and can only be battled on a second or third playthrough . He can be found within the Giant of Babil after the defeat of the four Archfiends , or on Mount Ordeals after the Giant of Babil becomes inaccessible . Battle . Geryon is armed with all of the Elemental Archfiends ' signature attacks . These include Scarmiglione ' s Gas , Cagnazzo ' s Tsunami , Barbariccia ' s Maelstrom and Lightning , and Rubicante ' s Inferno . It is also able to use Curse , Stone Touch , and a powerful physical attack . Tsunami and Inferno are more powerful than before - especially Tsunami , with which instant death cannot be avoided unless it is turned to absorption . If Kain is the only one left and he Jumps , Geryon will resort to Inferno to heal himself . Strategy . An effective way to defeat this boss is to equip all characters with Adamant Armor and Cursed Rings to turn the resistance of the elemental moves into absorption , and to use a Lunar Curtain on the main attackers , or on the whole party , to nullify Geryon ' s melee damage . With or without Cursed Rings and Adamant Armor , it is recommended to stall the battle until the last playthrough for the maximum augments . It is a good idea to level - grind the party to at least the higher 70s . Even if the party has no Adamant Armor Geryon can still be defeated . A full set of Crystal and Dragon equipment ( for Kain and Cecil ) plus a Cursed Ring will let them absorb everything except Curse and Tsunami . Giving Rydia and Rosa Luminous Robes , Gold Hairpins , and Protect Rings will halve some elemental damage . As for Edge , the only resort is the Protect Ring . Boosting magic defense and magic evasion through equipment will help , as there is no time to cast Shell later on . If the party is properly protected against status ailments Geryon will be defeated easily , though Curse is not such a huge issue . Kain must have Phoenix equipped , as Tsunami or Inferno can take out the whole party any time . After Geryon takes out the whole party the priority is reviving Kain and restoring his MP as Geryon acts quickly . Before facing Geryon , the player should ensure to have at least 20 Dry Ethers and Elixirs . Rydia and Rosa may also run out of MP mid - battle . If the party happens to survive Tsunami or Inferno , Rosa should restore everyone to full health as soon as possible ( dualcasting Curaja is the fastest way ) . Having the Darkness augment on any of the three attackers helps greatly . Focus would also be useful , but with Inferno and Tsunami debilitating the party it won ' t be easy to pull off . In addition to Curse , the attack might miss . Ultima with Limit Break is not really worth it as Geryon doesn ' t take much damage from the spell , and the turns can be used to heal , buff , or attack instead . The Dualcast augment on Rosa and Rydia is imperative . Omnicasting on Rosa and Fast Talker on Rydia are going to make a big difference . The first turn must be given to Rosa to cast Slow and omnicast Blink . Rydia ' s first turn should be used to cast Bio and Meteor . Cecil , Kain , and Edge should attack . Cry is also imperative . Cursed Elegy is bad for Kain , Edge , and Cecil — their attacks will miss . The player should use their turns to heal instead , and focus on the magic . While cursed , Edge must be careful about the weapons to throw . Kain should Jump to avoid the Curse and damage as much as possible . It is also a good idea to have Unicorn Horns or Remedies ready for Stone Touch . Etymology . Its naming follows the trend of christening the Four Fiends after demons depicted on the poem .
