Weapon upgrading
Weapon Upgrading (also known as Weapon Grinding) is a service available at the weapon shop where weapons are upgraded at the cost of meseta. Each weapon can be upgraded a maximum of 10 times with meseta. After the weapon has been upgraded 10 times, an Extend Code can be used to perform an Extend to strengthen the weapon further. After a weapon has been extended, an Extend Code ∞ can be used to perform an Extend ∞ on the weapon to improve its strength even further.
Weapons' attributes can also be upgraded through a function known as Weapon Synthesis. This requires extra copies of the weapon and Fusion Codes.
