Category
Description

Plop Plop
Creates a puddle that pulls and knocks down enemies.
Clean Up
Valby's performance increases while in Liquefied state.
Category
Description
Spiral Tidal Wave
Changed into a module for skill critical hit builds.
Singing Water
Skill 4 is modified to focus damage on powerful enemies. Creates a water puddle, accumulates Laundry-marked targets, and fires a water cannon.
Supply Moisture
Improved to allow Valby to be used as a firearm critical hit DPS. When attacking Laundry targets with a firearm, ammo recovery and increased firearm critical hit multiplier effects are added. Skill 3 applies a Laundry effect when attacking with a firearm and provides instant reload.
■ Monthly Weapon Balance: Enduring Legacy / Voltia

- Balance adjustments are being made to Enduring Legacy and Voltia.
Category
Description
Enduring Legacy
The firearm mechanic has been changed. Firing rate decreases the more you shoot, but firearm damage increases. Explosive incendiary rounds are also fired, reducing enemy fire resistance and increasing the weapon's fire-attribute damage.
Voltia
Retains its existing functionality with minor improvements. When multi-hits occur, the damage of the next chain current increases — maximizing effectiveness in combat with clustered monsters.
■ New Trigger Modules

- 3 New Trigger Modules
Category
Description
Explosive Aesthetics
A module for Esiemo. After placing 10 explosive projectiles, players gain the Finale effect, which triggers a larger chain explosion when using Skill 4, Arche Detonation.
Infiltration Mechanism
A useful module for the newly improved Valby. After using a status conversion skill like Liquefied, using Skills 1 or 2 deals additional damage to enemies, with the additional damage's attribute matching the equipped Reactor.
Current Bonding
A module that compensates for Ines's lack of single-target damage. After binding Colossus, commanders, or Tyrants with Skills 2 and 3, using Skill 1 deals greater damage.

- Ines New / Improved Modules
Category
Description
Plasma Ball (Existing Module Improved)
Continuously emits lightning around Ines, dealing damage to enemies within range. Skill 3 has been modified to move to a designated location and knock down enemies, making it suitable for close-range combat.
Plasma Condensation
A module that compensates for the lack of single-target damage. Conductors stack up, and when fully stacked, transform into powerful single-target damage. Skill 2 "Charge Concentration" can now be charged. Delivers higher efficiency in smaller-scale battles.
Plasma Bullet
A module for a firearm-build Ines. Multi-hit chance increases proportionally to MP, and Skill 1 "Induced Current" is a toggle skill that performs AoE attacks when firing. Skills 2 and 3 can be used to recharge Induced Current and gain a multi-hit multiplier buff.
■ Farming Loop Overhaul

- A major farming structure overhaul is coming for Descendants who have just entered Hard difficulty and those currently in the middle of farming.
- A research material called "Archive Shards" is being introduced, consolidating farming immediately after entering Hard difficulty. Archive Shards can be obtained from various Hard difficulty content, starting with 400%.
- Amorphous Materials are being consolidated into one per item, and Descendant Transcendent modules can now also be farmed in the same content where the Descendant's Amorphous Materials are farmed.
- Recommended Descendants will be displayed by content, guiding players on which Descendant to farm.
- 2-3 types of basic research materials scattered across regions are being consolidated into one type.
- Reactor Smart Drop: In 400% dungeons, only Reactors matching the currently played Descendant's attribute and Arche type will drop.
- Amorphous Material Forced Stabilization: As stabilization progresses, a gauge accumulates, and upon reaching 100%, players can select one of the Amorphous Material rewards to open. Amorphous Materials can also be opened directly from the consumables menu.
- The difficulty of Void Vessel and 400% has been lowered to help newly entered Descendants settle in.
- Upon completing the prologue, players will now start the game with normal Lepic, Viessa, and Ajax all unlocked.
