Biography
One of the most difficult super bosses in the Labyrinth of Chaos. He is randomly encountered in the Hades bonus floor or as a floor-100 super boss, after encountering the Hades Floor six times.

Pulling apart the fabric of space and time, World Breaker tears though the boundary of the world. With a gaze as cold as ice, he turns to face the party, declaring that he will destroy this world. With his extremely powerful attacks and immunity to all status effect and almost all standard elements, he appears very capable of doing so.

Upon defeating him, World Breaker himself seems to malfunction. He then utters a few lines, including telling Luka that he must “break the world”, before vanishing.

He briefly flashes in Luka's mind during the Yamatai Night Festival on the Alice route. As the party is enjoying the fireworks, they reaffirm their desire to protect the world, but Worldbreaker echoes back that it will be to destroy it. Although he denies that anything happened, Sonya looks dubious.

Strategy
Like his counterpart, Judgement, World Breaker is immune to almost all elemental/physical damage; only chaos and holy element skills are effective. While MP drain was very effective against Judgement, only 2 of World Breaker’s skills require MP, and those are harmless ones. MP drain against World Breaker instead can disrupt his standard attack pattern, making him more difficult to defeat (see below). Physical-type nullification is ineffective, since all of World Breaker’s major attacks are auto-hit. Magic-Reflect is also useless, since World Breaker uses only Physical-type and Auto-hit moves. Furthermore, even being able to keep up a 2-hit deflector at the end of each turn does not prevent World Breaker from breaking through your characters’ Endures and Auto-Revives; Sylph V2 hits through deflectors and dispels them, while Gnome: Gaia GH breaks through them by hitting the entire team 3 times. Elemental nullification is ineffective, since World Breaker’s main attacks are all chaos element. Since World Breaker is immune to all status effects, including “weakening”, there is no use in trying to inflict any on him.

Since World Breaker is immune to almost all standard elements, a holy or chaos element is required to deal damage. Chaos-element attacks are those like “Page 99999 of Chaos”, “Nuclear”, “Supernova”, or “Meteor”. Powerful Chaos-element attacks can be used by equipping certain Legendary LoC weapons. Nightmare characters from the Collaboration Scenario will also work, since their damage cannot be nullified in any way.

It’s possible for World Breaker’s moves to all be on cooldown – in that case, he will be inactive for a turn. As of 2.35, World Breaker can act during time stops, but his skill cooldowns will freeze, meaning if you have access to time stop via the collab character Mukuro or through Nuruko’s exclusive loc legendary weapon, you can potentially lock him down indefinitely by repeatedly using time stop. Although you will have to have to slowly wear him down with only your time stop user, which may take a very long time.

If you are fighting World Breaker before version 2.30, you can use Slayer elements to damage World Breaker. Human or Angel Slayer element will deal the most damage (150%), while other Slayer elements will be only 10% effective. Plenty of LoC items give Slayer elements to “Effect: +” moves, while Angel Slayer Talisman is available in-game. The Human Slayer combat ability is available to several races, particularly the Zombie race. This strategy no longer works after 2.30, as Slayers are no longer considered as elements.(Note: As of 2.23, descriptions of Slayer elements (“normal attacks deal 100% more damage…”) are not accurate.)

--- How to stack buffs vs. World Breaker ---

If your team is not strong enough to beat World Breaker head-on, then one way of dealing a lot of damage is to stack buffs on a few (or even one) offensive characters.

Especially if you can gain multiple actions per character, then stacking buffs will deal more damage (for instance, Full Power + Focused Spirit + Power Charge yields a x24 attack bonus on the next turn).

World Breaker has 4 “spirit” attacks, which are each chaos-element, auto-hit, buff him, and have a 5-turn cooldown (meaning that after being used, they cannot be used for 4 turns).


 * Sylph V2 hits each character once, goes through deflectors, and dispels buffs.


 * Gnome: Gaia GH hits the entire party 3 times, which means that it will break deflectors. If this move and any spread move (Sylph V2, Big Crunch, Nano Flare) are available, you should have at least one character with a 2-hit barrier, Auto-Revive, and Endure, to avoid losing.


 * Undine: Laser Piercer hits a single character 6 times.


 * Salamander: Final Cannon hits 8 times at pre-determined characters. Effect can be mitigated with Super Appeal/Super Hide.

Since Sylph and Gnome will respectively remove buffs and just knock out your active characters, they must be on cooldown in order for you to safely apply buffs. Due to World Breaker’s moves and their cooldowns, it’s inevitable that both Sylph and Gnome will both be on cooldown at some point *if you have not MP drained World Breaker*.

(If you forget when a spirit attack cools down: If, at the end of a turn, World Breaker “loses [spirit]’s protection”, then the following turn will be the last turn when that spirit is on cooldown.)

At this point, you should bring out your offensive character(s) and start buffing them. They should preferably have “Super Hide”, and your non-important characters should have “Super Appeal”, in order for your important character(s) to (with great likelihood) avoid Undine and Salamander. Make sure to keep your offensive character(s) protected with barriers to avoid damage from Big Crunch, Nano Flare, or a stray hit from Salamander.

If Sylph and/or Gnome comes off cooldown, and you are not finished buffing, place the offensive characters in your party reserve, and wait again until it’s safe to buff. Hopefully, you’ll be able to finish buffing before you run out of characters, and defeat World Breaker with a powerful attack.

--- Notes ---


 * Be sure to remove World Breaker’s appropriate spirit buffs if you are attacking with a non-Chaos element move that has an element that can be absorbed; if World Breaker has “Salamander” and you have “Salamander” active, your “Effect: +” attacks will always be absorbed. If you have a Chaos element applied, your attack will always go through absorb (for example, Nuclear).


 * If you have drained World Breaker’s MP he will always be able to “use” Daystar or Sword of Heaven’s Army,  since they will never actually activate, and thus never be on cooldown, allowing World Breaker to waste turns instead of being forced to use Sylph/Gnome. For example, if Gnome is on cooldown, but Sylph is not, World Breaker can waste turns and recharge Gnome, all while it’s unsafe to buff. Hence, if you rely on buffing a few characters to win, it’s not recommended to MP drain World Breaker, as the moves you seal are rather harmless, and make World Breaker much less predictable. .
