Who is Lucy and What is Their Playstyle?

This collaboration-exclusive character 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 using unique data anomalies and then cashes out with amplified point-blank strikes.

Based on her official combat parameters, this carry provides:

  • Hyper-Carry Performance: Boasting a high Base ATK of 425, she is 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 a monowire.
  • Basic Attack DMG Amplification: She provides specialized Basic Attack damage multipliers to bolster team utility and sustained rotations.
  • Data Crash Tuning: 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. She excels at shredding mechanical constructs and high-threat targets, but her advanced cyberware leaves her vulnerable. With a kit that balances high offensive scaling with a self-damaging mechanic, she can be quite squishy—meaning you must execute perfect dodges or run her alongside a dedicated defensive anchor.

How Do Lucy's Skills Work?

The core of this Resonator’s kit is about entering her enhanced state, managing data stacks, and unleashing devastating Heavy Attacks. Here is how her mechanics break down into simple terms:

  • Forte Circuit (Depths of Blackwall): Hitting enemies outside of her enhanced state generates TCP. Reaching 100% TCP transforms her skill 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 40% and upgrades her basic and heavy combos.
  • Heavy Attack (Multi-threading): While in Algorithm Compaction, building up "Root Access" lets her unleash a massive heavy attack. Crucial detail: If she has the SQL buff, this attack does double damage and consumes the buff. If she does not have SQL, the attack drains 20% of her current HP!
  • Resonance Liberation (Netrunner): This ultimate opens a "Protocol Interface" where you spend RAM to apply debuffs (like ATK reduction or stun) to marked enemies. Once the interface closes, it deals a massive nuke of Heavy Attack DMG.
  • Inherent Skills: Her passive, Ghost Cyberware, grants an auto-dodge shield after 8 seconds of taking no damage. Her other passive, Function Cracking, gives team-wide damage buffs when you defeat marked bosses.

Best Combat Rotation

  1. Step 1: Start with your supports to apply team-wide buffs and shields.
  2. Step 2: Swap to your main DPS and use Basic Attacks/Skills to build TCP to 100%.
  3. Step 3: Cast the Deadlock Resonance Skill to enter the Algorithm Compaction state and gain the SQL buff.
  4. Step 4: Perform Basic Attacks to build "Root Access", then hold the attack button for Heavy Attack - Multi-threading. (The SQL buff ensures double damage and prevents HP loss).
  5. Step 5: Cast her Resonance Liberation to apply network debuffs and finish with a massive nuke, then swap out.

What is the Best Weapon for Lucy?

To maximize this Spectro carry's potential, you need to focus on Heavy Attack multipliers and raw ATK stats.

  • Best-in-Slot: Spectral Trigger (5-Star)
    This signature pistol is tailor-made for her rotation. It increases ATK by 12% and boosts Spectro DMG by 15% when using a Resonance Skill. Most importantly, when she inflicts her special hack debuff, it grants a massive 25% Heavy Attack DMG Amplification and allows her Heavy Attacks to ignore 10% of the enemy's DEF.
  • Premium Alternative: Phasic Homogenizer (5-Star)
    A great fallback option. After a teammate triggers a Tune Break, this weapon grants a 20% All-Attribute DMG Bonus for 14 seconds, aligning perfectly with standard burst windows.
  • Budget Option: Solar Flame (4-Star)
    This accessible pistol is highly synergistic. Dealing Basic or Heavy hits increases both ATK and Heavy Attack DMG by up to 8.8% at maximum stacks. It fits her rhythm perfectly.

Which Gear and Stats Maximize Lucy's Damage?

Note: Specific signature Echo set data for this collaboration is currently unconfirmed in the raw data files. Based on her element and role, here are the standard recommendations.

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, 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.

Pair this Echo with a 4-piece set that boosts Spectro DMG (likely the new Reminiscence set that drops alongside her). If that set isn’t farmable yet, Celestial Light (5-piece) is your best traditional alternative for the raw Spectro DMG bonus. Lingering Tunes can also work for the ATK% if you have better substats.

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 (Premium stat for her)
  4. Energy Regen (Until comfortable with Liberation uptime)
  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 your fragile carry while hyper-buffing her heavy strikes. The ultimate Edgerunners team includes:
Wuthering Waves premium team overview for Lucy with teammates Rebecca and Shorekeeper

The Premium Comp: Lucy + Rebecca + Shorekeeper

  • Rebecca (Sub-DPS / Amplifier): This free 5-Star Electro teammate is the perfect partner. Her passive directly interacts with the hacking mechanic, granting the team All DMG Amplification. Furthermore, Rebecca's Outro Skill summons a turret that provides up to 70% Heavy Attack DMG Amplification. Because they share a special "Edgerunners' Bonds" passive, your main DPS automatically receives max stacks instantly.
  • Shorekeeper (Support / Healer): This Spectro Rectifier user keeps the team alive. Her Stellarealm ultimate grants massive Crit Rate (up to 12.5%) and Crit DMG (up to 25%) buffs. Because the cyber-hacker can drain her own HP with careless heavy attacks, Shorekeeper’s continuous healing and fatal-blow rescue passive (Life Entwined) are mandatory for survival.

What Materials Are Needed to Upgrade Lucy?

To fully upgrade this Spectro carry and her signature weapon, you will need to farm several material types. The exact quantities required to reach maximum level are broken down in the tables below:

Which Constellations (Resonance Chain) Are Worth Getting?

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

Level Effect Value/Verdict
R1 Grants interruption immunity during skills and a 20% ATK buff after Intro. Also copies defeated enemy buffs. Good. Makes her combos much safer to execute.
R2 Increases Ultimate RAM to 32. Resonance Skill deals an extra 300% DMG. Heavy Attack SQL multiplier jumps to 200%. Excellent (Best Stopping Point). A massive, front-loaded damage spike.
R3 Ultimate Override DMG +60%. Grants 20% Crit Rate and 50% Crit DMG during the Ultimate. Great. Turns her burst window into a guaranteed nuke.
R4 Inflicting hack debuffs grants all team members a 20% All-Attribute DMG Bonus for 20s. Decent. Adds strong team utility.
R5 Grants a massive shield (150% of ATK) when HP falls below 50%. Situational. Good for survival, but expensive for a defensive buff.
R6 Hacked targets take 60% increased Heavy and Hack DMG. Overpowered. Ultimate whale territory that breaks the game.

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. 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.
