Lucy Build Guide

What to know before spending pulls

Her complete damage loop exists at S0. The key account requirement is enough field time to build TCP and Root Access before using Multi-threading and Old Net Deep Dive. Rebecca is a particularly direct partner because Lucy's Intro enhances Rebecca's targeting and turret, while both characters interact with Hack.

Do you need the signature weapon?

Spectral Trigger is Lucy's featured weapon. At level 90 it has 588 ATK and 48.6% Crit DMG. Resonance Skill grants up to 40% Spectro DMG Bonus, and inflicting Hack - Shifting grants 30% Heavy Attack DMG Amplification plus 10% Heavy Attack DEF ignore for 14 seconds. Phasic Homogenizer has the same ATK and Crit DMG, adds 12% ATK, and grants 20% All-Attribute DMG Bonus for 14 seconds after anyone on the team uses Tune Break. The featured weapon follows Lucy's normal Skill and Hack loop; Phasic Homogenizer is useful when the team triggers Tune Break reliably, but its main bonus is conditional on that event.

Another character copy or the weapon?

S1 means Lucy's first Resonance Chain upgrade. It prevents interruption during Payload, Pulse Interference, Dual Threading, and Multi-threading; Intro also grants 20% ATK for 14 seconds. Its Quick Action effect can reapply recorded Spoofing Program statuses after the marked target is defeated. Spectral Trigger instead strengthens her Spectro and Heavy Attack damage during every normal cycle. Choose S1 when interruptions are breaking the Compaction combo or when repeated enemy waves can use Quick Action; choose the weapon for the more direct damage package.

Advice for your account

Easy rotation

Enter with Intro Skill, then use Payload and its automatic follow-up before casting Pulse Interference. Continue normal and Heavy Attacks until TCP reaches 100. Cast Deadlock to enter Algorithm Compaction and gain one SQL. Attack in Compaction until Root Access reaches 100, then hold Normal Attack for Dual Threading and follow immediately with Multi-threading. Multi-threading spends SQL for its 270% multiplier increase and unlocks Old Net Deep Dive. Cast the enhanced Liberation, select the Spoofing Programs needed for the fight, mark the targets, then hold Normal Attack to trigger Override and close the interface.

Opening vs. repeat cycles

Intro makes the next Pulse Interference grant 20 extra TCP, so an Intro cycle reaches Deadlock sooner. Deadlock resets after either Liberation, and casting Liberation clears TCP and ends Algorithm Compaction. Later cycles therefore restart the TCP build, but any 30-second Spoofing Program debuffs from the previous Override may still be active.

Why this skill priority

Resonance Liberation is first because Netrunner and Old Net Deep Dive contain Override and every selectable Spoofing Program. Basic Attack follows because most of Algorithm Compaction, including Thread Shredding, Dual Threading, and Multi-threading, is housed there. Forte Circuit and Resonance Skill control entry into that damage window.

Required buffs and assumptions

The full loop assumes Lucy stays on the field long enough to reach 100 TCP and 100 Root Access. Multi-threading should be used while SQL is available; otherwise it loses the 270% multiplier increase and consumes 20% of Lucy's current HP. Old Net Deep Dive must follow before Algorithm Compaction ends.
