• Use of Arche Activity
• Arche Activity Calculation

ㄴ Total Arche Activity

ㆍ Total Arche Activity is the sum of the Arche Activity values of the Descendant, Weapon, Reactor, External Components, and Fellow in use.

ㆍ If two or more weapons are equipped, only the weapon with the highest Arche Activity is included in the Total Arche Activity calculation.

ㆍ The Arche Activity of each equipment is the sum of the Arche Activity values of the growth elements that make up that equipment.

ㄴ Descendants

ㆍ Ultimate Status: The Arche Activity of an Ultimate Descendant is higher than that of a normal Descendant.

ㆍ Descendant Level: Arche Activity increases as the level rises. It does not decrease if the level is reset due to assigning a module socket type.

ㆍ Descendant Modules: Calculation is based on normal modules, Trigger Modules, and Ancestors Modules, but skill modules and sub modules are not included.

ㆍ Normal Modules: Arche Activity increases as the enhancement level rises. All fully enhanced modules have the same Arche Activity. The type and tier of normal modules do not affect Arche Activity.

ㆍ Trigger Modules: The higher the option tier, the higher the Arche Activity. If there are two or more options, the average value is applied. The type of Trigger Modules does not affect Arche Activity.

ㆍ Ancestors Modules: All Ancestors Modules have the same Arche Activity. The type and tier of Ancestors Modules do not affect Arche Activity.

ㆍ Arche Tuning: Calculation is based solely on the cost of node activations. Mutant Cells do not affect Arche Activity.

ㆍ Inversion Reinforcements: Since these are reset every season, these are not included in the Arche Activity calculation.

ㄴ Weapons

ㆍ Weapon Tier: The higher the weapon tier, the higher the Arche Activity.

ㆍ Weapon Level: Arche Activity increases as the level rises.

ㆍ Weapon Modules: Arche Activity increases as the enhancement level rises. All fully enhanced modules have the same Arche Activity.

ㆍ Weapon Options: The higher the option tier, the higher the Arche Activity. If the option tier is lost due to a Weapon Level Transmission, Arche Activity is calculated as 0.

ㆍ Unique Abilities: Arche Activity increases as the enhancement level of the Ultimate Weapon's Unique Ability rises.

ㆍ Core Options: The higher the level of the Core used and the tier of the Core options applied, the higher the Arche Activity.

ㄴ Reactors

ㆍ Reactor Tier: The higher the Reactor tier, the higher the Arche Activity.

ㆍ Reactor Level: Arche Activity increases as the level rises.

ㆍ Enhancement Level: Arche Activity increases as the Reactor's enhancement level rises.

ㆍ Reactor Options: The higher the option tier, the higher the Arche Activity.

ㄴ External Components

ㆍ External Component Tier: Arche Activity of External Components is the same regardless of the tier.

ㆍ External Component Level: Arche Activity increases as the External Component's level rises.

ㆍ External Component Options: The higher the option tier, the higher the Arche Activity.

ㆍ Core Options: The higher the level of the Core used and the tier of the Core options applied, the higher the Arche Activity.

ㆍ Set Options

ㆍ Arche Activities of 2-piece set options and 4-piece set options are the same.

ㆍ For External Component sets without a 2-piece set option effect, the Arche Activity of the 4-piece set option effects is set to double.

ㄴ Fellows

ㆍ Fellow Tier: Fellows do not have tiers and are assigned a default Arche Activity value.

ㆍ Fellow Level: Arche Activity increases as the Fellow's level rises.
