Weapons of legend were once wielded by incredibly powerful beings, gods, or similar powers. Some of these weapons are created in order to function as font for mortals. Others are created with the intent of slaying deities. Whatever the case may be, only one may exist at a time and if one is destroyed, another is created immediately. These weapons should be used as plot devices or boss weapons, and should NOT be a weapon a character has at the start of the game except for specific circumstances.
Legendary Weapons are required in order to kill a god, and once a weapon has become legendary a god has a copy of the weapon in their possession until they’re killed, and upon this occurring both forms of the weapon are destroyed: the deity’s form, and the mortal’s form. Deities cannot touch legendary weapons lest it injure them, and risk sacrificing their godhood. Legendary Weapons aren’t the only means of defeating a god, but killing a god requires a Legendary Weapon.
When a weapon states it grants a “+xkx vs. enemy type” this bonus is to attack and damage against that enemy type.
In addition, Reap is a special quality specific to some Legendary Weapons.
