Lucy is an A-rank Fire Support Agent in Zenless Zone Zero who packs a serious punch despite her rarity. Part of the Sons of Calydon, this baseball-wielding biker comes with three loyal boar minions that dish out off-field damage while she buffs the entire squad. Think of her as the "Bennett of ZZZ"—a humble support who quietly cranks up your team's damage output to eleven. As of 2026, Lucy remains a staple in many endgame compositions, and for good reason: her kit is stacked with ATK buffs, energy regeneration, and consistent Fire anomaly application. Whether you're a free-to-play grinder or a whale, this guide will help you squeeze every last drop of value out of her.

Best W-Engines for Lucy

Lucy's signature W-Engine, Kaboom, is hands-down her best-in-slot. It provides a hefty Energy Regen boost and, more importantly, a stacking ATK buff for the whole squad whenever any friendly unit lands a hit. Each ally can contribute one stack, up to four stacks, for a total of 16% ATK at max refinement. Since Lucy already buffs ATK with her EX Special, this weapon turns her into an absolute buff-bot beast.

If you don't have Kaboom, Weeping Cradle is the only S-rank support W-Engine currently available. It offers off-field Energy Regen and a damage amplification effect for the team, but its Pen Ratio main stat is wasted on Lucy because her boars don't benefit from it. Still, the energy and debuff make it a solid consolation prize.

Slice of Time is another option if you want to boost your team's Decibel generation and energy economy. It generates extra Decibels for Dodge Counters, EX Specials, Assist Attacks, and Chain Attacks, plus a flat Energy refund for Lucy. Again, the Pen Ratio main stat is not ideal, but the utility is nothing to sneeze at.

Disc Drive Builds

Lucy's disc drives should focus on maximizing her ATK buff (which caps at 600 total ATK) and keeping her energy flowing. There are two main builds:

Off-Field Support Specialist

  • 4-piece Swing Jazz: 2-piece gives 20% Energy Regen; 4-piece grants a 15% team DMG buff for 12s after a Chain Attack or Ultimate.

  • 2-piece Hormone Punk: +10% ATK.

Fire Damage Hybrid

  • 4-piece Swing Jazz: Same as above.

  • 2-piece Inferno Metal: +10% Fire DMG.

Main Stats:

Slot Main Stat
IV CRIT Rate / CRIT DMG / ATK
V ATK
VI ATK or Energy Regen

Substat Priority:

  1. CRIT Rate% / CRIT DMG

  2. ATK%

  3. Anomaly Proficiency

  4. Flat ATK

The support build is easier to hit the ATK cap with, while the Fire build turns her boars into mini-nukes. Either way, you can't go wrong.

Skill Priority

Always prioritize her Core Skill first—it's the engine behind her support capabilities. After that:

  1. Special Attack – Boosts the ATK buff from Cheer On and increases damage/daze.

  2. Basic Attack – Directly increases her boars' damage.

  3. Assist – Used more often than Ultimate or Dodge.

  4. Ultimate – Only increases damage, not the energy regen it provides.

  5. Dodge – Lucy plays off-field, so you'll rarely use it.

Best Bangboo

  • Bangvolver: With two Physical characters, its Chain Attack inflicts 100% more Anomaly Buildup. Perfect for a Physical team.

  • Booressure: Generates 60% more Energy for off-field characters when Ether bubbles hit allies. Helps Lucy keep her ATK buff up.

  • Rocketboo: With two Fire characters, Chain Attack inflicts 100% more Anomaly Buildup. Ideal for mono-Fire.

  • Cryboo: A weaker Rocketboo (60% more buildup) but still solid for triggering Burn.

Team Compositions

Lucy shines in two main setups:

Physical Team: Lucy + Nekomata + Piper

Everyone's additional ability activates, and Lucy's boars inherit her CRIT stats. Piper triggers Assault, Nekomata capitalizes on it, and Lucy keeps the ATK buff rolling. This team absolutely slaps.

Fire Team: Lucy + Soldier 11 + Koleda

Soldier 11 is your main DPS, Koleda stuns, and Lucy enables Burn while buffing ATK. Rocketboo makes Burn procs even more frequent, letting Soldier 11 go absolutely ham.

Final Thoughts

Don't sleep on Lucy! She's not just a buff bot—she's a reliable off-field damage dealer who keeps your team safe while her boars do the dirty work. As an A-rank, you'll eventually pull her, and when you do, build her. She fits into a shocking number of teams and scales beautifully with investment. In 2026, she's still one of the best supports in the game, and ignoring her would be a rookie mistake. Get out there, cheer on your squad, and let the boars run wild! 🐗🔥
