Very much worth pulling if you invest in any Rupture team — Lucia is the BiS HP/Sheer support, raising the damage ceiling for 
Yixuan, 
Yidhari, and 
Manato alike. Her buffs are extremely strong with good uptime; her only limitation is that she shines almost exclusively within the Rupture archetype and sees little use elsewhere.
Lucia scales purely off HP and needs no crit on herself. Key threshold: >=24,000 Max HP (per game8/prydwen/bluestacks) to max her team HP buff and Special Attack buff; once hit, prioritize Energy Regen for smooth EX Special/Ultimate cadence. Main stats: disc 4 HP% · disc 5 HP% · disc 6 HP% (or Energy Regen if energy-starved). Substats: HP% > flat HP > Energy Regen (ignore crit/ATK). Everything funnels into HP.
1) OPENER: enter with 60 Dream Points; go straight into a Basic string to Basic 5 so Aftershocks push Dream Points to 100 → enter Dream State and open Ether Veil: Wellspring (team Max HP buff). 2) In Dream State: use EX Special/Chain to apply Dreamer's Nursery Rhyme (team DMG buff) and Ether Veil, then quick-swap to the Rupture carry (Yixuan/Yidhari/Manato) inside the buff window. 3) OFF-FIELD: while backgrounded she auto-fires Aftershocks (consuming 25 Dream Points) to keep the squad's Fierce Attack buff up. 4) ENERGY TIP: if low on energy, DON'T dump EX while in Dream State — once it ends, EX -> Basic 5 to instantly restore uptime. 5) Loop: swap back to her whenever the DPS buff is about to expire to refresh.
Secret Friend: when Dreamer's Nursery Rhyme deals additional DMG, IGNORE 18% of the enemy's All-Attribute RES and gain +5% Decibel generation; adds a stacking Echo that extends/reapplies the Nursery Rhyme buff to the squad. This is the best VALUE stop for F2P: 18% RES shred multiplies every DPS she buffs, acting like a flat team damage node — many guides (game8/prydwen) suggest stopping at M1 on a budget.
Great Magician: while in Ether Veil, her Harmony (upgraded) attacks deal +15% DMG and Darkbreaker-state agents (Rupture/Sheer DPS) gain +15% Sheer DMG. A direct raise to the Rupture carry's damage ceiling — HIGH priority and the ideal cap for invested players. Still prioritize her signature Dreamlit Hearth BEFORE buying mindscapes.
The Best Partner: +2 levels to Basic/Assist/Dodge/Special/Chain. Skill levels usually don't matter for a support, but her Sheer buff to Darkbreaker agents scales with EX Special level: 900 → 948 at M3 (per game8). Still a small flat bump, mostly a stepping stone to M4 — low value.
Late-Night Hours: when Ether Veil activates or extends, grants 100 Decibels to the whole squad (once per 15s). Noticeably speeds up the DPS's Ultimate uptime for more bursts per stage — a solid medium bump, but no gameplay change. Only consider it after M2.
Dream Watcher: +2 skill levels again. Still flat numbers; the Darkbreaker Sheer buff reaches 996 at M5 (per game8). A bridge to M6 — low value.
The Never-Ending Journey: while in any Ether Veil, ATK increases by 2% of Max HP and Harmony ALWAYS crits with +30% Crit DMG. Turns her huge HP pool into personal damage and locks crit on Harmony — the biggest single jump. Very strong but whale-tier; most stop at M1/M2, only those with spare resources aim for M6 (skipping the filler M3-M5).
- BiS HP/Sheer support for the entire Rupture archetype: directly raises the damage ceiling of Yixuan, Yidhari and Manato regardless of element, thanks to HP/Sheer-based buffs that aren't element-locked.
- Deep, multi-layered buff package: team Max HP (Ether Veil), team DMG (Dreamer's Nursery Rhyme), Sheer buff for the DPS, and Fierce Attack while off-field — many amp layers in one support slot.
- Very cheap, easy build: just stack HP (no crit needed, no crit-disc RNG), and the ~24,000 HP target is easy to reach — very F2P-friendly.
- Strong, self-sufficient buff uptime: the Dream Point + Aftershock system keeps Ether Veil and buffs nearly permanent from the very start (enters with 60 points).
- Narrowly specialized: shines almost only in Rupture/Sheer teams (and partly Aftershock teams). Outside that archetype her HP/Sheer buffs add little, so she sees little use.
- HP-threshold dependent: needs ~24,000 Max HP for buffs to cap out; below it you lose noticeable value, so disc investment is still required despite the simple build.
- Energy-hungry for cadence: after HP is settled, you must balance Energy Regen so EX Special/Ultimate come up on time — starve her and buff uptime and the rotation break down.
Excellent in Shiyu Defense: a single-target support for a bursty Rupture carry (Yixuan/Yidhari + a Stunner like Ju Fufu/Trigger, or with Astra Yao in premium setups). Her HP/Sheer buffs + RES shred (with M1) pile heavy damage into the stun window, noticeably lifting the score on a Rupture half.
Also very strong in Deadly Assault: her buffs are percentage-based so they scale well against high-HP bosses; durable Rupture teams (Yidhari/Yixuan + Lucia + Stun/Pan Yinhu) or F2P comps (Manato + Lucia + Pulchra/Pan Yinhu) keep buff uptime high through long fights, regularly topping the Rupture-side scores.
