Fiend Dragon ( Final Fantasy VI ) The Fiend Dragon , also known as Doom Drgn , is an enemy in " Final Fantasy VI " . They only appear in a single hallway near the end of the tower before the party confronts Demon , as well as in a small " U - Turn " shaped cave area taken only by the 1st Party that links a laboratory and exterior area . Thus , since it ' s not unlikely the player will wander through both areas without a random encounter , the player may quite easily miss it . Battle . It is one of the most dangerous enemies in Kefka ' s Tower , mainly because it counterattacks with Heartless Angel frequently , which is unblockable and reduces the HP of the entire party to 1 . If this happens , it can mean an instant Game Over if no one in the party is immune to or absorbs Fire , because it can then use Southern Cross to attack the entire party for Fire - elemental damage . The Fiend Dragon also uses Northern Cross to inflict Frozen on characters ( although its own Southern Cross can remove the status ) , and Dissolve to give itself the Vanish status . They can sometimes appear in groups of two , making them all the more dangerous . Coliseum setup . Put Mog in the back row and equip the Paladin ' s Shield / Flame Shield , and Snow Scarf along with the best available helmet . Paladin Shield / Flame Shield will take care of Southern Cross . Snow Scarf , along with an appropriate helmet , will bring Mog ' s Defense to 255 which , along with his position , ensures his surviving any physical attacks following the use of Heartless Angel . Northern Cross will do nothing more than delay Mog , since the Frozen status will either be removed by Southern Cross or will simply wear off . Valiant Knife with Merit Award is a good offensive option depending on Mog ' s level and HP , since Fiend Dragon will most likely use Heartless Angel sooner or later , after which Valiant Knife will get a boost in damage due to Mog ' s low HP . One of the best ways to beat this monstrosity is to put in Gogo with the Paladin shield with Blitz , and Sketch . Sketch could get lucky and use Heartless Angel on the Dragon , effectively ending the battle on the next turn . One of the most effective ways of defeating it at lower levels is by using Umaro combined with an Angel Ring and the Berserker Ring . With a little bit of luck , the Fire and Ice absorption ( combined with the Angel Ring ) should be enough to prevent the Fiend Dragon from killing Umaro as low as level 35 ( obviously , once the first victory is secured , the player should repeat the process , but replacing the Angel Ring with Miracle Shoes ) . The player can also Steal useful Guard Bracelets from them ; though the Guard Bracelet is not as useful as the aforementioned Miracle Shoes , it can be bet in the Coliseum to win a Hero ' s Ring , a relatively rare Relic that acquiring in quantities otherwise requires a lot of time and gil invested at the Auction .
