World Items (ワールドアイテム, Wārudoaitemu) or World Class Items (世界級アイテム, Sekaikyū Aitemu) are the most powerful and legendary items in YGGDRASIL. They possess massive power that could potentially threaten the game's balance, thus, earning them the term "Balance Breakers". They are also known to be called the "crapped out".


In the game lore of YGGDRASIL, the World Tree was once covered with a countless number of leaves, but one day a gigantic monster appeared and devoured these leaves. The leaves were destroyed one by one, until only nine were left, making the Nine Worlds of YGGDRASIL. These World Items are said to made from remnants of those leaves, each equivalent to a world in power. The monster that devoured the original leaves would attack the remaining realms for these items. They were integral to the background story of the game: Players would step out into the unknown and face dangers in order to protect their own world.

In all of YGGDRASIL, there were only 200 World items. Each of them had their own unique ability, and some were powerful enough to destroy the game's balance. Of course, not all of the World Items had such game-breaking abilities. Even so, if a player managed to get hold a World item, that player's reputation in YGGDRASIL would jump to the highest level. Effects of a World Item can be resisted in only two ways: (1) Owning another World Item. (2) Getting special Job Classes.

While this is just a speculation, there was a guild that even said a World Item may possibly be dropped from level-breaking bosses. In particular, this being the Lords of the Seven Deadly Sins since they're classified under YGGDRASIL as a World Enemy. The guild believed that through defeating all seven of them, the World Item would appear from the monsters dropping it.

Normally, World Items could not affect holders of other World Items, but it would be a different matter unless if those holders happens to accept that influence. To begin with, all of that was actually made possible thanks to a patch created by the developers of the game.

Known World Items


Twenty is the name of 20 World Items that are unrivaled in terms of power. All of them could only be used once. If one needs to use it again, one should find the item all over again, regardless of difficulty of the process.

  • Longinus: It has the power to completely remove any target from existence at the expense of the user's own existence. There was no way to restore the data of anyone deleted by that World Item, other than by using the resurrection powers of other World Items. Neither cash items or resurrection spells would work. If someone were to use it on an NPC of Nazarick, it would even reduce the maximum creatable levels of NPCs — the special feature of a guild homebase.
  • Ahura Mazda: It has a potent effect on anything with a negative karma value, and its area of effect could span an entire world.
