Lucy Build Guide: Best Weapons, Echoes and Teams | WuWa 3.4

Who is Lucy and What is Their Playstyle?

This collaboration-exclusive Resonator steps onto the field as a dedicated Spectro Main Damage Dealer. Unlike standard carries who rely solely on raw bursts, her kit functions like a true network intrusion. She destabilizes targets with unique data anomalies, then shreds their defenses with amplified point-blank strikes.

Based on her official combat parameters, this carry provides:

• Hyper-Carry Performance: With a high Base ATK of 425, she's tuned to stay on the field and claim the lion's share of team field-time.
• Heavy Attack DMG Focus: Her primary damage profile scales massively through specialized Heavy Attacks using her signature monowire.
• Basic Attack DMG Amplification: She provides specialized Basic Attack damage multipliers to bolster team utility and sustained rotations.
• Hack Response & Data Crash: A combat debuff system that triggers severe frequency disruption and crowd-controlling stagnation fields.

In practice, playing this character feels like executing a high-stakes digital heist. Your netrunner excels at shredding mechanical constructs and high-threat targets, but her advanced cyberware leaves her squishy. With a kit that balances high offensive scaling and a self-damaging mechanic, you must execute perfect dodges or run her alongside a dedicated defensive anchor.

How Do Lucy's Skills Work?

Her core loop revolves around entering an enhanced state, managing data stacks, and unleashing devastating Heavy Attacks. Here's how the mechanics break down in simple terms:

• Forte Circuit (Depths of Blackwall): Hitting enemies outside her enhanced state generates TCP. At 100 TCP, her Resonance Skill transforms into Deadlock.
• Resonance Skill (Protocol Breach & Deadlock): Casting Deadlock forces her into the Algorithm Compaction state and grants a buff called SQL. This enhanced mode boosts her Spectro DMG by 65% (at level 10) and upgrades her basic and heavy combos. While inside, her Basic Attacks are replaced with Thread Shredding series, all considered Heavy Attack DMG.
• Heavy Attack (Multi-threading): Inside Algorithm Compaction, building up Root Access by hitting enemies lets her chain into Dual Threading and then the massive Multi-threading. Crucial detail: If she has the SQL buff, this final hit's multiplier skyrockets by 270% and consumes the buff. If she does not have SQL, the attack drains 20% of her current HP — so never skip the setup!
• Resonance Liberation (Netrunner): This ultimate opens a "Protocol Interface" where you spend RAM to apply debuffs like ATK reduction, DEF shred, or even turning enemies neutral. Once the interface closes, she slams the system with Override, a massive nuke of Heavy Attack DMG. If cast after Multi-threading, it upgrades to Old Net Deep Dive for a greatly increased Override multiplier.
• Inherent Skills: Ghost Cyberware grants an auto-dodge shield (100% damage reduction) after 8 seconds of taking no damage. Function Cracking applies a Botnet Mark on bosses; when a teammate defeats that marked enemy, she gains up to 25% All DMG Amplification and extra Hack DMG Multiplier for 2 minutes. If Rebecca is in the team, she shares this buff.

Best Combat Rotation

1. Step 1: Open with your supports to apply team-wide buffs and shields.
2. Step 2: Swap to your main DPS and use Basic Attacks or Skills to build TCP to 100%.
3. Step 3: Cast Resonance Skill – Deadlock to enter Algorithm Compaction and gain the SQL buff.
4. Step 4: Perform Basic Attacks (Thread Shredding) to build Root Access, chain into Heavy Attack – Dual Threading, then immediately hold attack for Heavy Attack – Multi-threading. The SQL buff ensures massive double damage and prevents HP loss.
5. Step 5: Cast her Resonance Liberation (now Old Net Deep Dive) to apply network debuffs and finish with a colossal nuke. Then swap out and repeat.

What is the Best Weapon for Lucy?

This Spectro carry craves pistols that boost Heavy Attack DMG, Crit DMG, and raw ATK.

• Best-in-Slot: Spectral Trigger (5-Star)
  Her signature weapon is tailor-made. It increases ATK by 12%, and casting Resonance Skill grants 20% Spectro DMG Bonus (stacking twice). Most importantly, inflicting Hack – Shifting grants a massive 30% Heavy Attack DMG Amplification and makes those heavy hits ignore 10% of the target's DEF. Synergizes perfectly with her SQL-buffed Multi-threading.
• Premium Alternative: Phasic Homogenizer (5-Star)
  A great generalist option. After any teammate triggers a Tune Break, this pistol grants a 20% All-Attribute DMG Bonus for 14 seconds, aligning smoothly with her burst windows.
• Alternative: Lux & Umbra (5-Star)
  Another 5-star pistol that boosts ATK by 12%. It grants 24% Heavy Attack DMG Amplification for 6s upon dealing Echo Skill DMG, and vice versa. While both buffs are active, your attacks ignore 8% of the target's DEF. It demands alternating between Echo and Heavy attacks, but provides solid uptime for skilled netrunners.

Note: Currently, no dedicated 4-star budget pistol perfectly replicates these effects. If you lack 5-star options, prioritize any high-ATK pistol with Crit or Heavy Attack substats.

Which Gear and Stats Maximize Lucy's Damage?

Best Echo Set

The collaboration introduces a new Echo: Reminiscence: Nightmare Adam Smasher. This is absolutely the BiS for Lucy.

• Default effect: Deals 16 hits of Physical DMG.
• Lucy Exclusive Effect (Tap): Deals Spectro DMG to nearby enemies.
• Lucy Exclusive Effect (Hold): Deals Spectro DMG and enters a special movement state that increases Movement SPD and slows nearby enemies' time flow. This is insane for both survivability and setting up your combos.

For her Echo set bonuses, the definitive end-game setup is:

• Shadow of Shattered Dreams (1-Pc): Inflicting Hack – Shifting (which she does constantly) grants 35% Basic Attack DMG Bonus and Heavy Attack DMG Bonus for 15s.
• Celestial Light (2-Pc): +10% Spectro DMG.
• Lingering Tunes (2-Pc): +10% ATK.

This combination maximizes her Spectro damage, raw ATK, and the all-important Heavy Attack multipliers that her Thread Shredding and Multi-threading scale with. This is her final, optimal Echo build.

Main Stats Priority (Echo Slots)

• 4-cost: Crit Rate or Crit DMG (aim for a 1:2 ratio)
• 3-cost: Spectro DMG Bonus x2
• 1-cost: ATK% x2

Substat Priority

1. Crit Rate / Crit DMG
2. ATK%
3. Heavy Attack DMG Bonus (her most premium scaling stat)
4. Energy Regen (until you can comfortably cycle her ultimate)
5. Flat ATK

Pro Tip: Because her exclusive Echo slows enemies, you can afford to lean slightly more into Crit DMG if you have good uptime on the slow field.

What Are the Best Team Comps for Lucy?

The ideal squad protects this squishy netrunner while hyper-buffing her heavy strikes. Here are the top configurations:

The Premium Comp: Lucy + Rebecca + Shorekeeper

• Rebecca (Sub-DPS / Amplifier): This free 5-Star Electro teammate is the perfect partner. Her Outro Skill summons a turret and grants the incoming Resonator Edgerunner Bonds. While others must stack the "Overlimit" buff from this effect, your main DPS instantly receives the maximum 70% Heavy Attack DMG Amplification. Rebecca also passively increases team Tune Break Boost and her ultimate grants a 20% ATK buff to all nearby allies.
• Shorekeeper (Support / Healer): This Spectro Rectifier user keeps the team alive and massively buffs crit stats. Her Stellarealm ultimate can grant up to 12.5% Crit Rate and 25% Crit DMG. Because the cyber-hacker can drain her own HP with careless heavy attacks, Shorekeeper's continuous healing and her unique passive—which rescues a Resonator from a fatal blow—are mandatory for survival.

The Defensive Comp: Lucy + Rebecca + Mornye

• Mornye (Support / Healer): If you don't have Shorekeeper, this 5-Star Fusion Broadblade user is a formidable alternative. Her Syntony Field provides continuous healing and a massive 50% boost to the team's Off-Tune Buildup Rate, meaning more frequent Tune Breaks. Once upgraded to a High Syntony Field, it also buffs team DEF by 20%. Her Outro Skill grants a flat 25% All DMG Amplification for 30s. Plus, her Proof of Boundedness inherent skill acts as a safety net, preventing fatal blows and capping massive damage instances—perfect for a carry who can accidentally drain her own HP.

What Materials Are Needed to Upgrade Lucy?

To fully upgrade this Spectro carry and her signature weapon, you'll need to farm a mix of credits, Exoswarm cores, and combustors. The exact quantities are broken down below:

Character Ascension & Skill Materials

Signature Weapon Materials (Spectral Trigger)

Which Constellations (Resonance Chain) Are Worth Getting?

If you have extra Astrite, pulling duplicate copies unlocks powerful Resonance Chains. Here is how they rank:

Is Lucy Worth Pulling?

Yes. If you need a hyper-carry who rewards thoughtful resource management and delivers massive burst damage, she is an incredible pull. This character truly shines if you already have Shorekeeper to provide healing and critical buffs, or Mornye as a sturdy defensive alternative. The fact that her best Sub-DPS (Rebecca) is given away for free makes building her premium team highly accessible. However, if you dislike managing complex mechanics or self-damaging HP risks, you might want to skip this banner.

Frequently Asked Questions (FAQ)

Why is my main DPS losing HP during combat?
This happens when you perform her Heavy Attack (Multi-threading) without the SQL buff active. To avoid this cyberware strain, make sure you enter the Algorithm Compaction state using a fully charged Deadlock skill first. This grants the SQL buff, which protects your health bar and doubles the damage of your next heavy strike!

How does the Resonance Liberation RAM system work?
When you cast the ultimate, the netrunner opens a Protocol Interface with a starting pool of 24 RAM (32 if you have R2). You spend this RAM to assign virus-like debuffs to enemies—like reducing their ATK or stunning them. Once the RAM is spent or the timer ends, she slams the system shut with an "Override" attack, dealing huge Spectro burst damage.

How does Rebecca's Outro Skill specifically buff this carry's Heavy Attack damage?
When you rotate from Rebecca to your main DPS, she passes over a buff called Edgerunners' Bonds. While other characters have to slowly stack up the "Overlimit" damage bonus by letting Rebecca's turret attack, this Spectro carry bypasses the build-up completely. She automatically receives the maximum 70% Heavy Attack DMG Amplification instantly upon taking the field, allowing you to launch into your high-damage combos immediately.
