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 genuinely believe they exist. Learning from other users will provide bonuses to both. However, power-up methods from different worlds will not work. Legendary Weapons have 3 power-up methods while Vassal Weapons have 1.

Universal

 * Absorption: Weapons can absorb loot such as items and materials to unlock new variations of the Legendary Weapon and may equip said variation if they meet its prerequisites.


 * Weapon Transformation: Weapons can transform into different variations that grant new equip bonuses including stats, skills, and abilities. Additionally, with enough experience or other prerequisites, the user may permanently retain the equip bonuses even if they switch transformations. (Some bonuses remain exclusive.)


 * 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.

S'yne's World

 * Unnamed power-up method: Using a form of compressed energy, the user is able to lend strength to others. This is a power-up method from one of the Legendary Weapons of S'yne's World.
