Lucia Overview

Rarity: S-Rank  |  Attribute: Ether  |  Specialty: Support

Lucia is a Dream-driven support engine — she repeatedly raises team Max HP via the new Veil (Curtain), supplies huge penetration, hands out flat DMG and crit-DMG boosts through Harmonies/Veil, and uses Aftershocks to deliver sustained, off-field damage and timed damage windows — perfect for rupture squads that want reliable uptime and HP-leveraged amplification.

What makes her tick in practice is timing and resource play: Lucia shines when you keep her Dream active long enough to extend Ether Veil: Wellspring, which lengthens the party survivability window and hands out repeated damage buffs—so she’s equal parts buffer and reliable secondary DPS.

 

Lucia Key mechanics & features

• Massive team HP: entering Dream activates the Veil which increases all squad members’ Max HP (5% base) and can be extended repeatedly — a direct survivability lever for rupture teams that benefits both sustain and HP-scaled effects.
• High “penetration” / damage-through: every Harmony Lucia triggers grants the squad Darkbreaker, which raises Sheer Force (the kit’s effective penetration power). That bonus scales with Lucia’s initial Max HP (large cap available), and while inside Ether Veil agents in Darkbreaker gain an extra Sheer DMG bonus — in practice this is Lucia giving teams substantial penetration punch.
• Strong raw damage & crit support: while inside any Ether Veil Lucia’s Harmony attacks deal +15% DMG, and Harmonies always crit, with Harmony CRIT DMG boosted by +30%; additionally, Dreamer triggers grant a temporary party DMG% buff (Dreamer’s Nursery Rhyme). Combine these and Lucia gives both flat damage and crit-damage amplification to primary strikers.

 

Lucia Skill Priority

Special ATK	⭐⭐⭐⭐⭐ (Top)
Ultimate	⭐⭐⭐⭐⭐ (High)
Core Skill	⭐⭐⭐⭐ (Medium)
Assist	⭐⭐⭐ (Medium)
Basic ATK	⭐⭐ (Low)
Dodge	⭐ (Low)

• Make EX Special your top target — it’s a Harmony hit that boosts final-hit HP scaling, applies Darkbreaker (big penetration), and helps extend Ether Veil when used in Dream, so it directly multiplies teammate damage.
• Next, level Ultimate — another Harmony that deals heavy Ether damage and extends Veil uptime, amplifying Lucia’s crit & damage windows.
• Then invest in Core Skill to stabilise the Dream loop, Ether Veil (team Max-HP buff) and repeated Dreamer’s Nursery Rhyme damage boosts — this is Lucia’s support engine.
• After that, Assist to keep Aftershocks and Harmony triggers rolling.
• Basic ATK comes next for steady DP generation.
• Dodge last — handy for counters but not priority for the support kit.

Lucia Best W-Engines

Signature W-Engine

Dreamlit Hearth

ATK: 713   HP: 30%

Dreamlit Hearth is Lucia’s signature W-Engine, perfectly complementing her support role and enhancing her synergy with Ether-based mechanics.

Why It's Ideal for Lucia:

• Enhanced Ether Veil: Lucia’s core skills rely on Ether Veil to boost team Max HP. Dreamlit Hearth strengthens this, adding damage and HP bonuses for better survivability and offense.
• Energy Regeneration: Boosted energy regeneration lets Lucia use her skills more often, keeping buffs and damage uptime consistent.
• Stronger Support: By amplifying Ether Veil effects, Dreamlit Hearth improves her healing and buffing capacity, enhancing overall team performance.

 

Alternatives W-Engine

Weeping Cradle (S-Rank)

Lucia often generates Dream Points via off-field Whims/Harmonies; the passive +0.6/s Energy Regen speeds her EX/Chain casts and lets her trigger Dream windows more reliably. Its stacking, time-ramped team DMG on struck targets directly amplifies Lucia’s Aftershock/Harmony follow-ups, turning each ethereal hit into bigger ally burst windows.

Kaboom the Cannon (A-Rank)

Kaboom’s per-hit ATK stacks reward frequent on-field hits — exactly the pattern Lucia encourages by creating Aftershocks and summoning ethereal strikes that provoke ally follow-ups. Those small, independent ATK stacks multiply the damage of Lucia-triggered follow-ups and help sustain increased DPS between her Dream activations.

The Vault (A-Rank)

The Vault boosts team DMG against a target whenever EX/Chain/Ultimate hits and also grants brief Energy Regen. Lucia’s kit converts EX/Chain/Ultimate windows into high-value team setups (Aftershocks, Dream state benefits); this item turns each of those decisive casts into an immediate damage multiplier plus faster recharge for follow-up ultimates.

 

Lucia Best Drive Discs

4-Piece Drive Discs Selection

Moonlight Lullaby

2-piece: Energy Regen +20%. 4-piece: When the equipper is a Support character and uses an EX Special Attack or Ultimate, the DMG dealt by all squad members increases by 18% for 25s. Repeated triggers reset the duration. Passive effects of the same name do not stack.

This Drive Disc set is tailor-made for Lucia. The 2-piece bonus (+20% Energy Regen) boosts her skill uptime, letting her trigger EX Specials, Ultimate, and Harmony follow-ups more often to maintain Dream loops and Ether Veil. The 4-piece bonus is even stronger: whenever Lucia, as a Support, uses an EX Special or Ultimate, all squad members deal +18% damage for 25s. This directly amplifies the rupture team’s damage output, synergizes with her Darkbreaker and Aftershock buffs, and maximizes the utility of her Harmony-triggered effects.

 

2-Piece Drive Discs Selection

Yunkui Tales	2-Piece Set: HP +10%
This Drive Disc set is ideal for Lucia because her kit scales heavily with Max HP. Her EX Special, Ultimate, and Aftershock effects all leverage her HP to increase final-hit damage, Darkbreaker penetration, and Ether Veil potency.
Swing Jazz	2-piece: Energy Regen +20%.
Lucia’s playpattern depends on frequent Whim → Harmony / EX activations and off-field Aftershocks that require repeated energy/activation windows to generate Dream state and trigger Aftershocks for allies. A +20% Energy Regen shortens the time between Lucia’s EX/Chain/Ultimate casts and helps sustain more frequent Dream windows and follow-up Aftershocks.

 

Lucia Drive Discs Best Stats

Main Stats

Slot 4	HP%
Slot 5	HP%
Slot 6	Energy Regen

 

Sub Stats

HP%	⭐⭐⭐⭐⭐ (High)
HP	⭐⭐⭐⭐⭐ (High)

• HP% & HP→ Lucia’s kit scales heavily with Max HP. Increasing her HP enhances final-hit damage on EX Special, Ultimate, and Harmony attacks, strengthens Darkbreaker penetration, and amplifies the Ether Veil: Wellspring effect for the whole team. Targeting around 24,000 HP maximizes both her personal damage amplification and her support utility.
• Energy Regen → Maintaining frequent skill uptime is critical for Lucia’s Dream loops, Harmony follow-ups, and Aftershocks. Energy Regen ensures she can consistently trigger EX Specials and Ultimates, keeping buffs and Ether Veil active.
• Energy Regen → If using Yunkui Tales 2-piece, prioritize Energy Regen substats to maintain skill uptime; crit stats can help boost secondary damage, but HP remains the dominant priority.

 

Lucia — Pull recommendation

The first number represents Mindscape Cinema, and the second number represents the level of her signature W-Engine.

• Low Budget (M0+S0): Playable and stable for story or light content. Lucia provides Dream Point generation and basic support, but her buffs and HP→Sheer conversion remain limited.
• Mid Budget (M0+S1 or M1+S0): Choose one focus — her signature W-Engine (M0+S1) for better buff uptime and easier rotations, or one Mindscape Cinema (M1+S0) for stronger scaling and smoother Dream-State transitions. Both are efficient for low spenders.
• Standard Budget (M1+S1): Ideal setup. Lucia’s Dream loops become reliable, her healing and Sheer buffs noticeably strengthen, offering excellent overall value.
• High Budget (M2+S1): Improves survivability, extends buff windows, and raises teamwide Sheer damage for faster clears.
• Unlimited Budget (M6+S1 / M6+S5): Maximum enhancement—longest buff uptime, strongest HP scaling, and top-tier support synergy for dedicated mains.

 

Lucia Best Team Comp

Yixuan + Ju Fufu + Lucia

DPS	Sub-DPS	Support	Bangboo
Yixuan	Ju Fufu	Lucia	Miss Esme

Lucia plays a primarily supportive role: her kit creates reliable windows for allies by extending field time and applying utility buffs that boost damage opportunities. Yixuan’s automatic extra lightning procs generate additional hit-triggers and technique tempo, while Ju Fufu supplies team-wide critical/burst amplification and crowd-control synergy. Lucia times her buffs to multiply Yixuan’s procs and Ju Fufu’s burst peaks, turning intermittent strikes into sustained, safer high-value damage phases.

 

Manato + Trigger + Lucia

DPS	Sub-DPS	Support	Bangboo
Manato	Trigger	Lucia	Belion

Lucia’s support function becomes even more pivotal: she focuses on buffing and timing windows so high-damage specialists can capitalize safely. Trigger accumulates squad Crit DMG stacks through stance and finishing moves, creating potent crit windows, while Manato applies sustained fire pressure and rupture damage as the primary damage engine. Lucia orchestrates tempo, extending Trigger’s crit windows and enabling Manato’s hits to land on exposed targets for cleaner, faster kills.

 

Yidhari + Ju Fufu + Lucia

DPS	Sub-DPS	Support	Bangboo
Yidhari	Ju Fufu	Lucia	Excaliboo

Lucia is the squad’s timing-and-buff conductor: her support extends damage windows and applies utility that turns risky plays into reliable ones. Yidhari trades HP for amplified Ice Rupture hits and needs protected, well-timed windows to safely ramp output. Ju Fufu supplies party-wide stun and crit/burst amplification that multiplies Lucia’s arranged opportunities. Together they run “Lucia creates the safe burst windows → Ju Fufu amplifies crit/burst → Yidhari converts those windows into high payoff damage.

 

Yidhari + Trigger + Lucia

Yidhari

Trigger

Lucia

Miss Esme

Lucia remains the tempo master: she extends and synchronizes windows so high-risk or stance-driven damage lands cleanly. Trigger builds squad Crit DMG stacks through Sniper stance and Aftershocks, creating periodic high-crit windows that Lucia times and prolongs. Yidhari then uses those curated windows to trigger HP-scaled Rupture spikes with lower risk. The loop is “Lucia opens/time windows → Trigger stacks crit pressure → Yidhari cashes in with amplified rupture hits.”

 

Conclusion

With Lucia on your team, battles become smoother and deadlier. As an Ether Support Agent, she amplifies Rupture units, extends buff windows, and boosts critical damage. Her precise timing ensures allies hit harder and survive longer, turning chaotic fights into controlled, high-efficiency strikes—proving she’s more than support, she’s the ultimate enabler of peak team performance.
