Causes Shadow damage to all targets.
Vivi Ornitier can use the Black Magic spell Doomsday, learned from his ultimate staff, Mace of Zeus. When cast, clusters of asteroids and meteoroids gather together in space to create one enormous meteor, which slowly descends and enters the atmosphere, colliding with the enemy and the surrounding area. It does a large amount of Shadow damage to the enemies and party. It can't be reflected and works with Return Magic.
Steiner can also use Doomsday ("Jihad" in Japanese) as a Sword Magic technique, but the difference between Vivi's spell version and Steiner's Sword Magic version is that Vivi's spell targets both enemies and party members, while Steiner only affects all enemies. A powerful combo would be to equip the party with Add-ons/armor which absorb shadow, allowing the party to heal massive amounts of HP with every casting of Doomsday. The spell is learned for 150 AP, costs 72 MP to use, and has a spell power of 112.
Doomsday appears as Ozma's most powerful ability when fought in The Weeping City of Mhach. In order to stop the ability from wiping the entire raid, player's must defeat the "Ozmashade" enemy during the parallel dimension of the fight.
In the Japanese versions, the ability name is actually Doomsday (ドゥームデイ, Dūmudei?), not using the original "Jihad" name from Final Fantasy IX. This is due to the game's development team using a reverse localization process for some of the ability names.
Final Judgment (最後の審判, Saigo no Shinpan?) was the summon attack of the Ozma Eidolon in the original free-to-play versions of the game. The attack dealt dark-elemental magic damage to all enemies and allies. Despite the different name, the attack's animation and effect are references to the Doomsday spell from Final Fantasy IX. The ability was removed from the premium versions of the game.
Doomsday is a reactive ability that costs 17 CP to equip. It is activated just once in Battle Music Sequences (BMS) when the player makes a chain of 50 hits. It deals magic damage, but also reduces HP by 30% and has extra strength. It is learned by Celes (level 80), Vivi (level 65), Shantotto (level 55), and Lightning #2 (level 90). It can be taught to any character by using the Doomsday Scroll.
The recurring Doomsday (ジハード, Jihādo?, lit. Jihad) attack appears as a unique set of abilities available to Ozma. The default version of Doomsday deals dark magic damage to the entire party and Ozma itself. A unique version known as Inscrutable Doomsday is available to the Inscrutable version of Ozma. This version only deals 5,000 damage to all targets.
Apocalypse Doomsday also appears as an ability to the Inscrutable and Conquer versions of Ozma, with the effects depending on the version fought. The former's version deals damage to all targets proportional to their current HP, ignoring their resistances, and removes their buffs. The latter's version deals heavy damage to all enemies. Lastly, Boundless Doomsday appears as the strongest attack of the Boundless version of Ozma. This version deals 99,999 damage to all targets.
In addition, Vivi's Super Soul Break, Doublecast Decay (W魔法・崩壊, W Mahō · Hōkai?, lit. Double Magic: Decay), is based on the Doomsday spell from Final Fantasy IX. The Soul Break deals four magic dark-elemental attacks to all targets. The ability can only be used if the player obtains Vivi's Mace of Zeus (IX). If Vivi completes battles alive with the weapon equipped, he can eventually master Doublecast Decay without needing to be equipped with the weapon and will gain a bonus of 10 to his magic stat.
Doomsday is comprised of the old English words dom and dæg meaning Judgement and Day. In Abrahamic religions, this refers to the time when God will descend from Heaven and judge the souls of mankind and will be rewarded or punished depending on the virtue of their souls.
Jihad" refers to a method used by practitioners of Islam to wage religious warfare on non-Muslims; the Crusades were once viewed as holy wars, so the meaning is not significantly changed. Jihad's literal meaning in Arabic is 'struggle', and it is also a term to describe the inner conflict a Muslim undergoes to make him/herself a better person."
