Lucia is one of Zenless Zone Zero’s most impactful Ether Support Agents, known for her powerful teamwide buffs, HP scaling, and sustained Ether Veil uptime that elevates both damage and survivability for Ether or Rupture compositions. Her kit revolves around Ether Veil: Wellspring, Aftershocks, and Harmony attacks that buff Sheer Force and overall squad performance.

Below is a detailed, up-to-date build guide with specific weapons (W-Engines), Drive Disc setups, stat priorities, skill focus, and team synergies to help you make Lucia a reliable backbone of your roster.

Role and How Lucia Works

Lucia functions as a support/buffer whose strengths come from increasing team Max HP, granting damage buffs, and applying penetration boosts through her abilities. Her skills scale strongly with HP percent, so stacking HP enhances both her support utility and the potency of her buffs to teammates.

Her kit also uses Harmony attacks (off-field attacks triggered by her EX Specials, Ultimates, or Aftershocks) to continually refresh team buffs and keep Ether Veil active, making her an excellent complement to high-damage DPS agents like Yixuan, Manato, or Yidhari.

Signature W-Engine

Dreamlit Hearth
This is Lucia’s best-in-slot weapon. It increases Lucia’s Energy Regeneration (ER) and boosts team Max HP and squad damage whenever Ether Veil or its extensions are triggered. Dreamlit Hearth also enhances her healing and overall support utility.

Strong Alternatives

If you do not have her signature weapon, these are solid options:

• Elegant Vanity (S-Rank): Provides team damage boost up to 20% after energy is spent and restores Lucia’s energy, helping her cast skills more frequently.
• Weeping Cradle (S-Rank): Offers off-field energy regen and periodic team damage buffs on hits.
• Unfettered Game Ball (A-Rank): Grants team Crit Rate on hitting enemies weak to Ether, useful in Ether-heavy teams.
• Kaboom the Cannon (A-Rank): Applies team ATK% buffs every time attacks land, which works well if you cannot get premium W-Engines yet.
• The Vault (A-Rank): Grants team damage and energy regen on Chain or Ultimate triggers.

Best Drive Disc Sets

Best Overall Drive Disc Combo

4-Piece Moonlight Lullaby + 2-Piece Yunkui Tales

• Moonlight Lullaby (4-pc): When Lucia uses an EX Special Attack or Ultimate as a Support, all squad members gain +18% damage for 25 seconds. This buff refreshes with repeated triggers and is central to her support role.
• Yunkui Tales (2-pc): Increases HP by 10%, which boosts Lucia’s buff potency and overall team survivability.

Alternative Drive Disc Combinations

• Moonlight Lullaby (4-pc) + 2-Piece Swing Jazz: If you want more Energy Regen, Swing Jazz’s +20% ER helps Lucia cast skills and Ultimates more frequently.
• Hybrid 2+2+2 Sets: You can mix Moonlight Lullaby, Swing Jazz, and Yunkui Tales to balance HP and ER, especially if you cannot complete the full set immediately.

Drive Disc Stat Priorities

To optimize Lucia’s effectiveness:

Main Stat Priority

• Slot 4: HP%
• Slot 5: HP%
• Slot 6: HP% or Energy Regen

Substat Priority

• HP% (highest priority)
• Flat HP
• Energy Regen
• CRIT Rate (secondary)

Lucia’s kit revolves around her HP scaling and ability to sustain buffs and harmony triggers. Reaching around 24,000 HP in combat is often recommended to maximize the potency of her Darkbreaker penetration and Ether Veil buffs.

Skill and Talent Priorities

While specific talents and traces vary by playstyle, a general priority for Lucia is:

1. Core Skill: Raises Max HP and triggers buff windows
2. Special Attack: Main source of Harmony triggers and follow-ups
3. Ultimate: Provides a robust teamwide buff and extends Ether Veil duration
4. Chain Attack: Bolsters sustain and refreshes team buffs

Because Lucia relies on Harmony effects to refresh her buffs and apply teamwide bonuses consistently, boosting her Core Skill and Special Attack ensures smoother support uptime.

Best Team Compositions

Lucia is especially potent in Rupture teams that leverage her buffs to amplify the primary DPS characters.

Premium Rupture Support Team

• Yixuan (Main DPS)
• Lucia (Support Buffer)
• Ju Fufu (Sub-DPS)
  This setup uses Lucia’s buffs to lift Yixuan’s damage ceiling while Ju Fufu provides additional secondary output.

Versatile Rupture Team

• Lucia (Support Buffer)
• Yidhari (Main DPS)
• Soukaku or Lycaon (Enhance Support/Stun)
  Yidhari benefits heavily from Lucia’s sustained HP buffs and Darkbreaker penetration, while Soukaku or Lycaon provides additional damage windows and control.

Support for Manato Rupture

• Lucia (Support Buffer)
• Manato (Main DPS)
• Pulchra or Burnice (Support/Stun)
  Manato’s damage spikes when combined with Lucia’s extensive buffs, ensuring strong burst and sustain.

These team builds take full advantage of Lucia’s strengths by aligning her support buffs with high-damage output agents.

Gameplay Tips

• Lucia performs best when you keep Ether Veil active as often as possible. Her ability to refresh it with Harmony attacks makes her ideal for sustained buff loops.
• Mount her with Energy Regen support via Drive Discs like Moonlight Lullaby or Swing Jazz to reduce downtime between skill casts.
• Prioritize building HP first to unlock her strongest buff thresholds and improve the potency of teamwide effects.

Final Thoughts

Lucia is one of Zenless Zone Zero’s most capable Support Agents today. Her HP-based scaling, teamwide buffs, and synergy with Rupture compositions make her a vital addition to high-end squads. Building her around Dreamlit Hearth, Moonlight Lullaby + Yunkui Tales, and strong HP Stats ensures she delivers consistent support while empowering your damage dealers.
