Black Elemental ( Final Fantasy X - 2 ) The Black Elemental is a boss in the 40th cloister of the Via Infinito under Bevelle . It was once Jyscal Guado , and is the strongest fiend in the Elemental family of " Final Fantasy X - 2 " . Battle . Black Elemental ' s Defense is 255 and its Magic Defense is 254 , making most physical and magic attacks ineffective . It uses Flare and Ultima , which can easily deal 9 , 999 damage to one or all party members respectively without proper preparation , being that it has 250 Magic Power . Flare can be reflected back to the boss , dealing over 1 , 000 or 2 , 000 damage . It also uses Berserk , which can also be reflected . Ultima cannot be reflected , as it hits the entire party . After defeating the Black Elemental , a chest is left behind . It contains six accessories , one of them being the rare Cat Nip . Strategy . If the party has the Dark Knight dressphere , and have learned Charon ( Self - Destruct ) , and are highly level ed , using it once or twice on the boss will defeat it . Another useful move is the Dark Knight ' s Darkness ability , which ignores Defense and Magic Defense . An easier strategy would be to have a Songstress use the Magical Masque dance to nullify all magic attacks , allowing one to attack safely . The easiest method is to start with three Gunners and then use the Cheap Shot ability , which does a critical attack regardless of Defense . In three turns , if the characters are at high enough levels , one can leave the battle unscathed . Alternatively , if the party have enough gil , a Samurai ' s Spare Change ability can instantly defeat the boss at any level . The player should equip the Highroad Winds Garment Grid to ensure the first strike . Another tactic involving Gunners is to use Tableturner on Black Elemental . Black Elemental ' s Defense is 255 , thus Tableturner will invoke great damage upon it , maybe even killing it in one hit if one ' s strength is high enough and / or one is lucky enough to land a critical hit . Another a simple strategy is to use the Blue Bullet Annihilator learned from the Experiment , which ignores all magic defense . Even with modest stats by Chapter 5 when Black Elemental is encountered it will almost always hit 9 , 999 damage without Break Damage Limit resulting in an easy win with one move . There is also a way to survive the Ultima attack head on by having Break HP Limit and using a Stamina Tablet or Stamina Tonic to double the party ' s HP . If a girl ' s dressphere had a high HP boost with Crystal Bangle equipped , their HP should break the HP limit to survive the Ultima attack . Using the White Mage dressphere , and equipping accessories and a Garment Grid to boost magic defense will make Ultima survivable . An Oath Veil , Crystal Bangle , and the Valiant Luster Garment Grid can provide maximum Magic Defense . The party should cast Shell as soon as the battle begins , and Ultima will only deal around 1400 damage . The player can use Vigor to heal . Players can have the other two girls in damage - dealing dresspheres to speed up the fight , though they will need frequent reviving . Black Elemental can also be bribed for approximately 65 , 000 gil . Creature Creator . Fiend Tale . In the Fiend Tale endings , another notable Dark Elemental was created from the spirit of a young girl who believed that she was a daughter of a Maester in Bevelle Temple . Having studied the traditions and rituals of Yevon since the time of her youth , knowing the inner workings of Bevelle Temple , she wanted to become a Maester like her father . She even befriended another girl who wanted to become a Maester . She was attacked by an Al Bhed assassin working for an Anti - Yevon movement . She found it odd that someone like her , having a virtuous life , ended up becoming a fiend instead of being sent . With Shinra creating a pocket world from her memories , the Dark Elemental learns she was a decoy and that her friend was the Maester ' s real daughter with her dead body buried in secret . It appears the real daughter died during Sin ' s attack on Bevelle . Stats . Like its weaker brethren of the Elemental family , it has pitiful Strength , Luck , and Evasion . The Agility is rather mediocre . However , the Black Elemental ' s power lies within Magic , and it has absurdly high Defense and Magic Defense ( even at the lowest of levels ) , and decent Accuracy .
