Legendary Weapons/Weapon Effects

One of the many ways wielders of Legendary Weapons or Vassal Weapons can power-up is by expanding their collection of weapons. This can be done by either absorbing different materials, copying another weapon of the same type or having it forcibly unlocked by a powerful creature or magic. Each different weapon form provides different bonuses to user's stats or abilities. These bonuses come in two forms: Equip Bonuses and Special Equip Effects. As a short summary, Equip Bonuses can eventually become a passive skill no matter what form the weapon is currently in while a Special equip effect is limited to a specific weapon form.
