Project Clean Earth Chipset Stat Priority and Build Guide

To build an effective Chipset configuration in Project Clean Earth, prioritize Percentage Attack (ATK %) and Cooldown Reduction (CDR), fill your grid with your highest-rarity chips, and slot Damage Reduction to survive incoming swarm damage.

Unlike temporary perks acquired when leveling up inside a stage run, Chipsets grant permanent passive bonuses to Bernard before an encounter begins. Because weapons scale from Bernard's base stats, socketing the correct modules early prevents enemy waves from overwhelming your build before your deck abilities fully come online.

Chipset Category Overview and Stat Priorities

Every module fits into one of three core roles. Offensive attributes form the foundation of any build, while defense and utility ensure active uptime during dense swarm encounters.

Chipset Category	Key Attributes	Build Priority	Primary Function
Attack (Offensive)	ATK %, Flat Attack, Crit Chance, Crit DMG	Top Priority	Accelerates mob clearing and single-target boss burst.
Utility (Functional)	Cooldown Reduction (CDR), Energy Recharge, Speed	High Priority	Maximizes deployment frequency of orbital lasers, turrets, and explosives.
Defense (Protective)	Damage Reduction, Max HP, Shielding	Baseline Threshold	Prevents sudden burst deaths from mutant elites and ranged attacks.

Stat Priority Hierarchy

When evaluating secondary bonuses across modules, follow this priority ranking:

Tier 1 (Core Focus): Percentage Attack (ATK %) and Cooldown Reduction (CDR).
Tier 2 (High Impact): Flat Attack, Critical Strike Chance, and Critical Damage.
Tier 3 (Situational Utility): Movement Speed, Energy Recharge, and Collection Radius.

Flat Attack and ATK % provide the most reliable returns because every weapon in your deck scales directly from base attack. Cooldown reduction functions as the strongest secondary modifier, shortening the cycle time of your active offensive cards and wide-area control skills.

How to Configure and Upgrade Your Grid

1. Prioritize Rarity Over Secondary Sub-Stats

Base attribute jumps between rarity grades outweigh minor secondary bonuses. Always socket your highest-tier modules into the grid first to maximize Bernard’s overall power rating before trying to optimize specific sub-stat rolls.

2. Choose Percentage Damage Reduction Over Flat HP

Neglecting defensive slots leaves Bernard vulnerable to charging elites and stray projectile bursts. When allocating defensive slots:

Select Percentage Damage Reduction ahead of flat HP boosts.
Damage reduction scales more effectively with in-stage recovery items, shields, and passive healing drones by increasing your effective health per hit.

3. Match Socketed Stats to Your Deck Archetype

Stationary and Deployment Builds: If your deck relies on turrets and barricades, combine utility, attack speed, and cooldown reduction to increase structure uptime.
Kite and Projectile Builds: If your deck uses beam weapons and mobile hit-and-run tactics, lean into raw damage multipliers, critical strike chance, and critical damage.
Boss Encounters: Prioritize high critical values and single-target damage to clear deep boss health bars before enrage mechanics fill the arena.

4. Upgrade and Merge Core Damage Chips First

Merging duplicate lower-tier chips unlocks higher-rarity versions with higher stat caps and extra sub-stat slots.

Do not spread upgrade currency evenly across your entire inventory. Funnel enhancement resources into your primary damage-scaling chips first. Accept workable transitional defensive rolls on offensive chips, and save scarce reroll resources until your core damage setup is fully stabilized.
