Lucy Gameplay and Playstyle

Resonator information
	Rarity	5★ (collab)
	Element	Spectro
	Weapon Type	Pistols
	Team Role	DPS

Lucy (5★) Lucy is a Spectro Pistols resonator who functions as a Main DPS, specializing in Heavy Attack and Tune Hack - Shifting DMG. Her gameplay revolves around cycling between her base state and Algorithm Compaction to build up and unleash a series of enhanced attacks.

In her base state, Lucy builds TCP through Basic Attacks, Resonance Skill - Payload, and Resonance Skill - Pulse Interference, the latter granting Digital Handshake to passively generate TCP over time. Once TCP is full, Payload and Pulse Interference are replaced with Resonance Skill - Deadlock. Casting Deadlock transitions her into Algorithm Compaction and sets up her core damage loop.

While in Algorithm Compaction, Lucy gains a Spectro DMG Bonus and a stack of SQL, with her Basic Attack and Heavy Attack upgraded to Thread Shredding and Single Threading. Hitting targets builds Root Access, and at full stacks, Single Threading becomes Dual Threading, chaining into Heavy Attack - Multithreading. Spending SQL on Multithreading massively increases its damage multiplier, and casting it upgrades her Resonance Liberation - Netrunner into the stronger Old Net Deep Dive.

Lucy's Resonance Liberation opens the Protocol Interface, where she spends RAM to apply Spoofing Program effects that mark, debuff, and nuke enemies before unleashing Override. She also pairs naturally with Rebecca, as her Intro Skill: Outdated Hallucination enhances Involuntary Sharing on Rebecca and triggers her turret's Overload, while her Function Cracking inherent skill grants both of them Network Backdoor when teammates defeat marked Overlord Class or Calamity Class enemies.
