The screen turns purple, health bars melt, and missions end before the enemy can even find cover. That is the power of the Corrosion meta in Girls’ Frontline 2: Exilium. At the heart of this toxic storm are two Sentinels: Klukai, the limited-time AOE goddess, and Peritya, the relentless follow-up turret.
Whether you are looking to erase entire squads in a single turn or build a support-attack engine that never stops firing, this Klukai Peritya guide covers the builds and synergies you need to dominate the current endgame.
Klukai Overview

Klukai finally has Mechty on the right track for every mission.
Klukai is a Sentinel and the undisputed queen of AOE. Her kit centers on spreading Corrosion and exploiting the Devastating Drift ultimate, which resets its cooldown if she secures multiple kills. She is built to delete groups of enemies in a single turn, making her the fastest farmer in the game.
- Seiyuu: Ai Nonaka
- Stat Priorities: Attack Boost, Attack, Crit Damage, Crit Rate
Breakpoints:
- V3: Allows Klukai to activate her Ultimate twice even against solitary boss enemies.
- V6: The gold standard. It automatically detonates Corrosive Infusion and Toxic Infiltration, massively boosting her raw damage output.
Since Klukai is a limited powerhouse, pushing for V6 is the goal for total map domination. She represents a top-tier investment that defines the current high-end meta for Gunsmoke.
Klukai’s Skills & Keys

Her Devastating Drift ultimate can be cast again if multiple targets fall.

These Fixed Keys turn Toxic Infiltration into a relentless cycle of damage.
Top Picks
- One Fell Swoop: Increases damage dealt by 30% if Devastating Drift only hits one target.
- Strong Support: Gains 1 point of Confectance Index for every Support Attack performed by allies.
- Limit Break: Reduces the Ultimate’s width to 3 tiles but increases damage by 10% for each tile reduced.
Situational & Additional Keys
- Moment of Doom: Re-inflicts Corrosive Infusion on survivors of Toxic Infiltration. Use this if you want more AOE range over the raw damage of Limit Break.
- Murderous Return (Common Key): Adds 5% Attack Boost. Increases the next AOE attack by 10% if Confectance is full at the start of the turn.
Attachments: Phase Strike (V1 and below) or Corrosion Boost (V2+)
Klukai’s Team Recommendations
Klukai thrives when paired with other Corrosion units or specialists who can feed her Confectance through support actions.
The Purple Rain Squad (Corrosion Meta)
- Klukai: The primary AOE carry and debuffer.
- Peritya: The follow-up turret. Every time Klukai hits a group, Peritya triggers a support attack to finish them off.
- Mechty: The glue for this team. She increases the team’s Corrosion effectiveness and triggers extra attacks.
- Suomi: Provides the shields and stability needed to let Klukai play aggressively in the middle of enemy packs.
Klukai’s Signature Weapon | Skylla

Crocodile Tears stacks extra damage every time Corrosion damage is dealt.
- Effect: Increases AOE damage by up to 25%. Each instance of Corrosion damage increases total damage by up to 4%, stacking for a maximum 20% boost.
- Imprint Skill: Increases damage to URNC units by 2.5%, plus another 2.5% if the target is already Corroded.
- Trait: Ignores 10% defense on phase weakness hits, doubling to 20% if it’s a Corrosion weakness.
- Alternatives: Make sure to get Klukai to V6 before prioritizing this. Planeta, Golden Melody, or her standard 416 are solid placeholders.
Peritya Overview

Peritya pursues her targets without respite, even if she forgets the mission.
Peritya is a Sentinel specialized in relentless AOE follow-ups. Her Chain Reaction passive is her bread and butter: whenever an ally deals AOE damage, Peritya immediately launches a support attack. This makes her the perfect partner for any character with large-scale attacks.
- Seiyuu: Noriko Hidaka
- Stat Priorities: Attack Boost, Attack, Crit Damage, Crit Rate
As a member of the targeted standard pool, you should aim to max her out at V6 once you have finished your QJ and Tololo. She serves as a high-value long-term project for any dedicated commander.
Peritya’s Skills & Keys

The Multi-Compilation ultimate deals massive damage based on the number of targets hit.

Fixed Keys like Brief Respite ensure Peritya is ready for battle from the start.
Top Picks:
- Temporary System Maintenance: Gains 1 Confectance for every 10 points of stability damage dealt.
- Impromptu Cat and Mouse Game: Grants Movement Up II at the end of the turn if she has mobility remaining before attacking.
- Friendly Contact: Adds 4 points of stability damage to the primary target of Fixed Erosion.
Situational & Additional Keys
- A Brief Respite: Start the battle with 3 Confectance. This is a big help for boss fights where you need an early Ultimate.
- All Points to Damage (Common Key): Adds 5% Crit Rate. Increases damage by 7% if an active skill hits 2 or more targets.
Attachments: Phase Strike (Without Mechty) or Corrosion Boost (with Mechty)
Peritya’s Team Recommendations
Peritya reaches her full potential when she has allies who can constantly trigger her support attacks.
The Support Attack Engine
- Peritya: The out-of-turn damage specialist.
- Klukai: Provides the constant AOE triggers Peritya needs for her passive.
- Mechty: Adds even more layers of follow-up damage and elemental synergy.
- Sabrina: Useful for gathering enemies into clusters with Calorie Overload so Peritya’s AOE skills hit more targets.
Peritya’s Signature Weapon | Optical Illusion

The Resonator passive rewards AOE attacks with massive damage boosts.
- Effect: Hitting 2-3 targets increases the damage of the next skill by 20%, with another 20% boost if that skill is an AOE. At max level, it has a 100% chance to apply two debuffs on hit.
- Imprint Skill: Increases damage to Varjagers by 2.5% (doubled when using a basic skill).
- Trait: Applying AOE damage grants a debuff. If a target has 3+ debuffs, she ignores 15% of their Cover damage reduction.
- Alternatives: Optical Illusion is available in the exchange shop. Otherwise, use Mjölnir (Battle Pass) or her standard Pecheneg-SP.
