Legendary Weapons

The Four Legendary Weapons(伝説武器) are later referred to as the Four Heavenly Weapons(聖武器) since many religions formed centering around the Legendary Heroes. The major religion in Melromarc is the Four Saints Faith that worship all the Legendary Heroes equally, but there is also Three Heroes Church, a radical faction those who dislike Demi-Humans, that only worships the Legendary Sword, Spear and Bow, excluding the Shield as its guardian of Demi-Human. The major religion in Silt Welt is the Shield Faith that worships the Shield Hero only. After the final wave the legendary weapons, except for Naofumi's Shield, gained the ability to be summoned and dispelled by their owners at any time. As a result of the world fusing with Glass's World, there became a total of 8 Holy Weapons since the world being a fusion of 8 different original worlds. While the new Heroes of the Legendary Weapons are summoned in later generations, the Shield has not reappeared due to Naofumi still possessing the Shield as a God.

The Legendary Weapons have 3 basic ability categories that appear by default which indicate the weapon has been strengthened:
