Longinus (聖者殺しの槍) is one of the Twenty World Items of YGGDRASIL.
During Ainz Ooal Gown's raid on the Great Underground Tomb of Nazarick, one of the guild members wanted to use Longinus against the Lord of Helheim.
This World Item enables the user to pick whichever target to delete from existence. However, it came with a cost where the user must pay the same price like the target as he/she had to also delete oneself. After having the character's data deleted by this World Item, unless another World Item was used for revival, there was no other way to come back alive.
In other words, it was impossible to restore the data of anyone deleted by that World Item if one did not use the resurrection powers of other World Items. Neither cash items or resurrection spells would effectively work. In case someone were to use it on a Custom NPC, it would even reduce the maximum levels of NPCs created, the special feature of a guild base.
- According to Christian lore, the Spear of Longinus was used to stab Jesus Christ and was drenched with his blood. This name was taken from the roman centurion, who thrust the spear into Christ's side at the crucifixion.
