Weapon upgrading

A player upgrading their Rapid Stream.

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.

Weapon Synthesis

See also: Elemental Correction

In the Weapon Shop, the Weapon Synthesis option allows fusing up to 10 copies of a weapon into a target weapon of the same name using a Fusion Code to increase its elemental percentage.

• Rules for percentage increase:
  • For each weapon that's a different element than the target weapon (including neutral), target weapon's element increases by 1%.
  • For each weapon that is the same element as the target weapon, target weapon's element increases by 2%.
  • For each weapon that is the same element as the target weapon, and have at least 30% element, target weapon's element increases by 3%.
  • The target weapon's element is capped at 50% when increased using fusion.

• A neutral weapon or a weapon above 50% cannot be used as the target weapon.
• An extended weapon can be used as both the target weapon or the fusion materials.
• 1 fusion code is consumed regardless of how many weapons are used as material.
