Feolthanos Exultant Feolthanos Exultant is the final boss in " " , and the second - last form taken by Feolthanos . It is a monstrosity composed of three parts : Feolthanos Medi , the torso , Feolthanos Dex , the right arm , and Feolthanos Sinis , the left arm . All three are classified as Group Leaders , and all three must be felled to win . If the game progress is 100 % completion , Exultant ' s level raises to 99 , including his two supports , Dex and Sinis . Battle . The player ' s party of five group leaders starts out in the southwestern section of the map , flanked by two allied Summoning Gate s . Feolthanos Exultant lies to the northeast : Medi is straight ahead , at the end of a large staircase , while Dex is to Medi ' s right and Sinis to Medi ' s left . Several battalions of Wing Wraith s guard each part . Each component of Feolthanos Eternal has the ability to summon four more Wing Wraiths at certain intervals . They do this via three circles of light that lie near to each part . Once each section of Feolthanos Exultant is destroyed , Wing Wraiths may no longer be summoned from that part . These summoning circles are not Summoning Gates ; that is , the allied party cannot attempt to " capture " the source of Wing Wraiths . Feolthanos Dex should be the first target . Its attack , Judgement , hits all units for heavy damage no matter where they are on the field . Thankfully , Dex will only use this attack at a rate of approximately once every 30 - 40 seconds . Next up is Sinis . Its attack , Condemnation , deals heavy area damage to all units around it . The player ' s Melee and Flying units are the only ones who need to worry about this , but approaching Wing Wraiths will attack the party ' s Healing and Ranged units from behind . Medi is last . The units can climb the staircase and whittle it down to about 50 % of its total HP without any retaliation , but for the constant spawning of Wing Wraiths . Once Medi reaches this halfway point , Bahamut is summoned . The party must try to defeat the scion quickly before it can cast Mega Flare . Medi ' s passiveness ends at this point . He begins using the Faithless Cry at regular intervals , at a greater frequency than Dex ' s Judgement . Faithless Cry sends a destructive beam of energy straight outwards , engulfing the entire staircase and everything in front of it . This attack , combined with the increased rate of Wing Wraith summoning , makes Medi difficult to approach . Faithless Cry is used slightly more often than summoning Wing Wraiths ( for each five Faithless Cries there is one second difference ) . Strategy . The player should begin by summoning more Rank II Espers onto the field with the Rank III Esper , and use them to attack Feolthanos Dex and wipe out any Wing Wraiths on the way . It is important to destroy this arm first , as Judgement can put the party in trouble . After the Arm is destroyed , the summoning gate for Wing Wraiths is destroyed along with it . Afterward , the party should regroup back in front of Medi moving on to the left arm , called Sinis . It will use Condemnation every now and then , but it is only a problem for units up close , such as Vaan and Filo . Wing Wraiths will try and hit the party ' s Ranged units from behind , and if that occurs , the party should turn their attention to them and wipe them out before attacking Sinis again . When Sinis falls another summoning gate for Wing Wraiths will fade away . The party can again regroup and heal in the center . The Wing Wraiths will only attack from the front . Medi will not use Faithless Cry until its health is lowered to 50 % . It is best not to use Quickenings as they will be needed later . Once Medi is down to 50 % Bahamut will appear , and Medi will start sending a massive beam called Faithless Cry . Everyone should run down the stairs and off to the side to avoid this , and leave the party ' s Rank III Esper , and some Rank II Espers , to distract Bahamut . One should keep sending Espers until Bahamut is dead , then cast stat enhancing moves on the player units before going for the final charge . Medi will still use Faithless Cry frequently , however , it is not so bad as Bahamut is dead , and all that are left are some Wing Wraiths . Now the party can use all of their Quickenings . If Faithless Cry is too much to deal with , the party can also find a spot from the right side of the podium to attack the core . Balthier and Ashe can attack consistently while the ranged abilities from Kytes , Lluyd , Basch and Penelo can also . The others can shield the duo by fighting the Wing Wraiths and Bahamut . Whittling down the core ' s HP with only leaders takes time , but the party is shielded from Faithless Cry . A good tip is to summon the Rank III Yarhi under Basch while he uses Cover and let the Rank III Yarhi attack Feolthanos alone while Basch , together with all healing units , stands close to a Summoning Gate , so Basch gets his damage healed . His Quickening can also be used to make his group temporarily invincible . Also , if one does not let the Rank III Yarhi attack the Wing Wraiths , they can do much damage to raise the Quickening frequency , and when there are around twenty Wing Wraiths , no more will be summoned .
