Elemental Archfiends ( boss ) The Elemental Archfiends are bosses in " Final Fantasy IV " fought in the Giant of Babil . Prior to the fight , the Archfiends were revived by Zemus so they could give one last group attack upon Cecil Harvey and his party . The bosses are fought one after the other . In the SNES , PlayStation , " Advance " and Final Fantasy IV Complete Collection versions , the order of the fight is Scarmiglione , Rubicante , Cagnazzo , then Barbariccia ; this is the same elemental order that the Four Fiends were fought in the original " Final Fantasy " . The Nintendo DS version rearranges the last three to put the fiends in the same order the bosses were first encountered , Scarmiglione , Cagnazzo , Barbariccia , and Rubicante . In some versions of the game , the Archfiends are susceptible to the Second form glitch . Strategy . The first stage of the fight is pretty easy , since all the player has to do is Dualcast Curaja . It is best to heal debuffs with Scarmiglione comes since it is likely for him to recast any debuffs the player has restored . He is still weak to Fire , so Ifrit or Firaga from Rydia and / or Firaga from Fusoya are good . Fusoya can also heal along with Rosa . He also still has the Cursed Elegy , of course , as a counter . When up against Rubicante , the player can use the same strategies as in the first encounter , except this time Fusoya replaces Kain — he works well as a second Black Mage ( casting Blizzara and Blizzaga , for example ) or as an additional White Mage if needed . If the player has completed the sidequest in the Feymarch and have access to Leviathan they can should use it here , as it is particularly devastating against Rubicante and can easily cause 9 , 999 HP of damage . An alternate strategy is to cast Haste on Rydia , then use Shiva or Leviathan when Rubicante opens his cloak ( More preferable with Shiva as she is faster . ) , then use Steal with Edge . After around four turns of this , Rubicante should fall . Since Rubicante should not be able to use Inferno when in his cloak , he will only be able to physically attack . Rosa can either revive characters killed with Rubicante ' s physical attack , or cast a Fire spell on Rubicante . Against Cagnazzo , Cecil should attack , Edge should use Blitz , Fusoya and Rydia should use Thundaga and Thunder spells while Rosa uses Cure . Barbariccia is immune to physical attacks , but magical attacks are capable of harming her . Edge and Cecil have little to contribute offensively , so Rydia and Fusoya should focus on dealing out as much damage as they can while Cecil and Rosa focus on keeping everyone ' s health up . Barbariccia does not counter attacks as much , but she does attack more frequently than before . Though it is not mentioned in the bestiary , Holy magic is incredibly effective against her , so Fusoya can cast Holy or Rydia can summon Dragon . If Rosa is a high enough level , she can Dualcast Holy dealing aproximately 19998 damage . Barbariccia is also unintentionally weak against Lightning . This bug is fixed in " Advance " remake .
