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.

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.

Raphtalia's World

 * Mastery: Using the same weapon would improve its stats up until it is fully mastered. This power-up method was first available to the Legendary Sword hero.


 * Energy Transfer: When you have gained mastery in using a weapon, you could reset its mastery level and release the amount of energy you had invested in it. Finally, any items that you had absorbed into the weapon could also be turned into energy. This power-up method was first available to the Legendary Sword hero.


 * Increasing Rarity: By imbuing a weapon with energy gained from resetting mastery levels, you can increase its rarity level and the weapon’s abilities. A weapon's rarity can be repeatedly increased starting at common (C), then uncommon (UC), and so on. This power-up method was first available to the Legendary Sword hero.


 * Smelting: You can power up a piece of equipment using ores. There is a chance of failure. This power-up method was first available to the Legendary Spear hero.


 * Spirit Enchantment: Pieces of monsters' souls that have been absorbed into a weapon can be used to imbue the weapon with special powers. This has no chance of failure-maybe. This power-up method was first available to the Legendary Spear hero.


 * Status Enchantment: Stats can also be increased by absorbing items dropped from monsters. This power-up method was first available to the Legendary Spear hero.
 * Power Up: The power of a weapon can be raised by equipping it with certain ores. This never fails. This power-up method was first available to the Legendary Bow hero.
 * Item Enchantment: Items that have been absorbed into a weapon can be turned into energy, and that can be used to raise the percentage of various stats. Success is based on probability, decreasing with each successive enchantment. Upon failure, the item enchantment level is reset to 0. This power-up method was first available to the Legendary Bow hero.
 * Job Level: You can increase specific stats by using the energy contained in absorbed monsters or items. Upon filling the level gauge for the desired stat, the stat is increased and the level gauge is reset with a cooldown timer. This power-up method was first available to the Legendary Bow hero.
 * Sharing: Share the power-up methods from other legendary weapons and vassal weapons. This power-up method was first available to the Legendary Shield Hero.
 * Trust: Trusting and being trusted leads to increased abilities. This power-up method was first available to the Legendary Shield Hero.
 * Energy Boost: The heroes have energy called "EP" that they draw out automatically as power from the weapons, and this is always active. Assigning this energy to skills will allow more powerful skills to be used. This energy is like a combination of SP and life force and is eventually required to learn Liberation-class magic. This power-up method was first available to the Legendary Shield Hero.
 * Power-Up Points: Points were acquired based on your current level, and they could then be spent on magic (Staff) or skills (Gauntlets)  the restriction to this power-up method is that the heroes must be working together for this power-up method to work. This power-up method was first available to the Seven Star Staff hero and the Seven Star Gauntlets hero.
 * Enhanced Customization Via Money: You must spend money to enhance yourself. It only works when combined with other power-up methods. It also cancels out failure at refinement. This power-up method was first available to the Seven Star Projectile hero.

Glass' World

 * Experience Points: By using a weapon, it gains experience points. As the weapon levels up, it gets stronger. This power-up method was first available to the Legendary Hunting Tool hero.
 * Ofuda: Pieces of paper can be attached to the legendary weapon in order to add different functions. This power-up method was first available to the Legendary Hunting Tool hero.
 * Magic Residue: Once the enemy has been defeated, the legendary weapon can absorb its magic power or any magic residue in the air. This magic power can then be used to power up the legendary weapon. This power-up method was first available to the Vassal Fan hero.
 * Refinement: Successful increasing the refinement will increase the power of the weapon and show a plus beside the name. This can be done multiple times but there is a chance of failure. The power-up method was first available to the Vassal Katana hero.
 * Spirit Enchantment: Similar to the power-up method from Raphtalia's world. Pieces of monsters' souls, or items, that have been absorbed into a weaponcan be used to imbue the weapon with special powers. This power-up method was first available to the Vassal Scythe hero of this world.
 * Item Boost: Items held within the legendary weapon provide bonuses based on what the item is. This power-up method was first available to the Vassal Boat hero.
 * Enhanced Status Via Money: Similar to its counter-part from Raphtalia's world but instead of providing enhancements and cancelling out failures with money, the user can buy status for cash. Statuses like +1 to magic, increased maturation rates, or magic recovery speed can be bought. This power-up method was first available to the Musical Instrument hero.
 * Food Level: Eating food increases a food level gauge that is different from regular levels. Levelling up causes statuses to increase. Different food changes which statuses are increased. This power-up method was first available to the Vassal Mirror hero.
