🎯 Skill Analysis

Normal Attack: Locked Thread Priority: 5/5

Perform up to 4 consecutive attacks dealing Spectro DMG. In Algorithm Compaction mode, Basic Attack is replaced with Thread Shredding (counts as Heavy Attack DMG).

Resonance Skill: Protocol Breach Priority: 4/5

Three skill variations: Payload (charge forward, inflicts Hack - Shifting), Pulse Interference (cuts target, grants Digital Handshake for TCP regen), and Deadlock (enters Algorithm Compaction mode).

Resonance Liberation: Netrunner / Old Net Deep Dive Priority: 3/5

Deep dive into cyberspace for 10s. Choose up to 7 Spoofing Programs (each costs RAM). Mark targets in view, then trigger Override for massive Spectro DMG. Old Net Deep Dive is the empowered version after Heavy Attack - Multi-threading.

Forte Circuit: Depths of Blackwall Priority: 2/5

TCP (max 100): Gained from dealing damage. At 100% TCP, skills become Deadlock. Root Access (max 100): Gained in Algorithm Compaction. At 100%, Heavy Attack becomes Dual Threading → Multi-threading. Algorithm Compaction: +65% Spectro DMG Bonus for 8s.

👥 Team Compositions

Lucy's kit benefits from having multiple different attributes in the team. The more diverse your team, the faster she builds resources.

Premium Team (With Shorekeeper)

Lucy (DPS) + Rebecca (Sub-DPS) + Shorekeeper (Support)

Shorekeeper provides healing, buffs, and Spectro resonance. Rebecca applies Hack - Shifting and off-field damage. Lucy enters Algorithm Compaction for massive burst.

Cyber Duo Quick-Swap

Lucy (DPS) + Rebecca (Sub-DPS) + Verina (Support)

Rebecca provides Havoc sub-DPS and DEF shred. Verina heals and buffs ATK. Quick-swap between Lucy and Rebecca for Hack synergy.

F2P Spectro

Lucy (DPS) + Spectro Rover (Sub-DPS) + Baizhi (Support)

Spectro Rover provides Spectro resonance and sub-DPS. Baizhi is the free healer. Budget but effective for all content.

Rotation Tips

Optimal Rotation

  1. Start with Shorekeeper: Cast Resonance Skill to apply buffs, build Concerto Energy.
  2. Swap to Rebecca: Apply Hack - Shifting, cast Skill for debuffs.
  3. Swap to Lucy (Intro): Gains TCP, cast Payload for initial Hack.
  4. Build TCP: Normal Attack combo + Pulse Interference until 100 TCP.
  5. Cast Deadlock: Enter Algorithm Compaction, gain SQL stack.
  6. Build Root Access: Thread Shredding + Single Threading until 100.
  7. Cast Dual Threading → Multi-threading: Consume SQL for +270% DMG, inflict Hack - Shifting.
  8. Cast Old Net Deep Dive: Empowered Liberation with all Spoofing Programs active.
  9. Swap out: Trigger Outro skill, restart cycle.

🔗 Resonance Chain

S1 - The Moon, a Ticket, and a Dream

Immune to interruptions during Payload, Pulse Interference, Dual Threading, and Multi-Threading. Intro Skill grants +20% ATK for 14s.

S2 - The Blackwall, the Past, the Escape

Starting RAM increased to 32. Pulse Interference deals additional 450% ATK Spectro DMG. SQL DMG bonus increased from 270% to 560%.

S3 - Cyberpunk

Override DMG Multiplier +50%, Crit DMG +100%. Hack Response - Data Crash DMG +65%.

S4 - No Living Legends in Night City

After casting Liberation, gain +30% ATK for 20s. When HP is below 50%, gain 15% DMG Reduction.

S5 - Netrunner's Legacy

Resonance Liberation level +3. Spoofing Program - Cyberpsychosis affects Elite enemies.

S6 - Dream of the Moon

After Old Net Deep Dive, enter Transcendent State for 10s: +50% Spectro DMG, attacks generate double TCP/Root Access.

Worth Pulling? S1 is the sweet spot for most players. S2 is excellent for quick-swap teams. S4 makes her a team buffer. S6 is whale territory but provides the highest damage ceiling. S0 Lucy is already S tier.
