Legendary Weapons/Power-up Methods

Overview
Weapons have various strengthening methods that are selectively revealed to the user's interface upon assignment. Other users can enable these systems only if they know roughly what the method does, which weapon the method is from, and they genuinely believe the method exist. Learning from other users will provide bonuses to both. However, power-up methods from different worlds will not work. Legendary Weapons each have 3 active power-up methods and 1 passive power-up method, making for a total of 4. Meanwhile Vassal Weapons have 1.

 * Absorption: Weapons can absorb loot such as items and materials to unlock new Weapon Forms of the Legendary Weapon and may equip said Forms if they meet its prerequisites, such as having a high enough Level or if another Form or Forms in the same series are unlocked first. Things absorbed by the weapons to unlock new forms are not destroyed, and can be accessed again from the Inventory.


 * Weapon Transformation: Weapons can transform into different variations that grant new Equip Bonuses and Special Effects including stats, skills, and abilities. Additionally, with enough time spent with a form equipped, the user may "Unlock" and passively retain the Equip Bonuses even if they switch transformations, such as "+1 Defence" and "Air Strike Shield". If two weapon forms have the same unique bonuses, such as Poison Resistance Up (Medium), then upon unlocking one, the other is replaced by a different Equip Bonus, usually a flat stat boost equal to the relative power of the weapon form. Equip Bonuses of different levels, such as (Small) and (Medium), have their effects stack. Some bonuses, known as Special Equip Effects, remain exclusive to their specific Weapon Form and can only be used when that form is equipped.


 * Weapon Copy: The user can copy weapons of a similar class to the Legendary Weapon that they encounter and store them for later access. Equip bonuses may still require materials to unlock.
