Guild Weapon

Guild Weapon is a type of item and physical symbol made by a Guild representing it in YGGDRASIL.

Overview
Guild Weapons are a necessary requirement when properly creating a Guild. They are also powerful items that can store huge amounts of data. Even if the Guild Weapon is designed poorly, it will still be an unparalleled weapon. However if broken, it signifies the worst possible scenario for a guild.

When broken, all members of the guild will have the title [Symbol of Failure] floating over their heads. It does not have any special effects, but it is the proof of shame.

To remove this Symbol of Failure, the same members must once again remake their guild.

Thus to protect their guild's existence, these items were typically kept hidden away in safe places and not used for their tremendous powers. Because a guild would be disbanded if its associated guild weapon was destroyed. Even Ainz Ooal Gown, a guild which existed at the peak of YGGDRASIL, was no exception to this.

Abilities and Powers
A Guild Weapon can alternate changes to a Custom NPC's original setting. For instance, this includes rewriting the backstory of an NPC to their whim.

Trivia

 * According to the Web Novel, there are classes that cannot have the Symbol of Failure, and there are also classes that can be nothing except to be the one that breaks the Guild Weapon.
