Lucy — Review & Analysis

Lucy

Lucy is a 6★ Intellect Reality DPS built around accumulation: each Incantation spends 10 stacks of [Electric Charge] for bonus damage, while her Ultimate grants [Pragmatism], making every attack count as effective against ANY Afflatus (+10% effectiveness multiplier) so enemy typing can never wall her. Her standout is the snowball engine: every enemy that leaves the field refunds charge, adds [Data Iteration] (+4% ATK) and fires an extra AoE [Kinetic Conservation] — she hits harder the longer a fight runs. Insight III also emits a [Force Field] that raises the whole team's effectiveness multiplier, so Lucy carries damage while doubling as a light buffer.

Strengths
  • [Pragmatism] makes every attack effective against any Afflatus (+10% multiplier), erasing type disadvantage and keeping her flexible against all enemy types.
  • Strong snowball: consuming Electric Charge adds damage, and each enemy kill refunds charge + [Data Iteration] (+4% ATK) + fires an extra AoE [Kinetic Conservation] with 50% penetration.
  • Not selfish: the Ultimate emits [Force Field] granting allies +10% effectiveness multiplier, while Insight II bakes in +10% Crit Rate.
  • Covers both single-target and AoE (Incantation I/II), handling lone bosses and packs alike.
Weaknesses
  • Her Intellect Afflatus stands outside the counter cycle — Pragmatism only fixes her offense, not her defense.
  • Accumulation-dependent: she needs Electric Charge (fed by the team's Passion/Moxie) and stacked [Data Iteration] to reach full power, so early rounds are weak, and she has no self-heal or shield.
Build Priority

Prioritize the Ultimate first — it's the operating core: it unlocks [Pragmatism], the kill-driven snowball engine, and the team [Force Field] buff; then raise Incantation I as her single-target finisher. Since Lucy scales on ATK and crit (Data Iteration + Insight II), pick a Psychube geared toward ATK / Crit Rate and Crit DMG; avoid healing-oriented lines, which don't suit this DPS role.

Euphoria

Official Euphoria effect text for Lucy, by branch and level.
Branch 1
Level 1

At the start of the round, if not under a [Pulsing Field] of any level, deploy [Pulsing Field Lv.1]. After casting a reinforced incantation, transfer up to 10 stacks of [Dynamo] into the [Pulsing Field].

Level 2

When entering battle, gain 20 stacks of [Dynamo]. After reinforcing an incantation, gain 1 stack of [Data Iteration].

Level 3

Gain [Amplified Surge].

Level 4

Reinforced incantations no longer consume [Dynamo]. No longer gain [Dynamo] when an enemy dies. When under a [Pulsing Field], reinforced incantations additionally deal ([Conservation of Energy]'s Reality DMG x50/70/120%) Reality DMG based on the array's level. When under [Pulsing Field Lv.3], for every stack of [Dynamo] owned, reinforced incantations additionally deal 8% Reality DMG. Reinforced incantations benefit from Ultimate Might at a 100% rate, and for every stack of [Data Iteration] owned, this rate increases by 10%.

Teams with Lucy

Dynamo Overdrive · Dynamo

Ulrich and Charon both carry the Dynamo tag and pair it with Ultimate/Moxie respectively — Dynamo resource generated by one feeds the other's payoff. Lucy adds a third Dynamo source at A+-tier damage but needs her Euphoria. Ms. NewBabel survives on the front line with Riposte/Shield/Moxie while the Dynamo cycle spins up.

Dynamo Second Wave · Dynamo

Enigma, Corvus and Lucy all tap into Dynamo together with Ultimate — combining it across three kits at once outperforms any single carry doing it alone. Ms. NewBabel keeps the line-up alive with Shield so that payoff has time to land.
