Release2.3

Lucia is an Ether Support Agent built entirely around the Rupture specialty, and she's still the best buffer for it by a wide margin. Once in her Dream state, she keeps an Ether Veil up and gives the squad Max HP, up to about 900 Sheer Force, +30% CRIT DMG and +20% DMG, while healing on the side. She's part of almost every top Rupture team, from Yixuan to Starlight Billy, Yidhari and Banyue.

Lucia

HP Support

W-Engines

Dreamlit Hearth BiS
S · HP%
Her signature and the most used option by far: HP% main stat, Energy Regen, and squad +25% DMG and +15% Max HP whenever she activates or extends an Ether Veil (almost permanently).
Energy Regen +0.4/s; activating or extending an Ether Veil gives the squad +25% DMG and +15% Max HP for 45s.
Weeping Cradle
S · PEN Ratio
Strong S-Rank alternative: her frequent off-field Aftershocks keep its DMG-taken debuff up surprisingly often.
Off-field Energy Regen +0.6/s; the wielder's hits make the target take 10% to 20.2% more DMG from all units for 3s.
Unfettered Game Ball
A · Energy Regen
A-Rank that can rival her signature when the boss is weak to Ether (party-wide CRIT Rate), much weaker otherwise.
Attribute Counter effects raise all units' CRIT Rate against the target by 12% for 12s.
Kaboom the Cannon
A · Energy Regen
Generalist A-Rank with squad ATK% stacks. Usable, but Rupture Agents scale mostly on HP.
Each squad member landing a hit grants the whole squad ATK +2.5% for 8s, up to 4 stacks.
[Reverb] Mark III
· HP%
B-Rank placeholder with an HP% main stat, suggested by Game8.
Chain Attacks or Ultimates give the squad ATK +8% for 10s (20s cooldown).

Teams

Recommended teams

Meta: Yixuan & Dialyn

Lucia's most used team in the current Shiyu Defense and Deadly Assault. Lucia boosts Yixuan's Sheer Force better than anyone, and Dialyn adds Ultimate conversions and +40% DMG. Bangboo: Belion, whose Additional Ability needs at least 3 copies with Yixuan as the only Yunkui Summit Agent.

Yunkui: Yixuan & Ju Fufu

The second most used Lucia team, and Game8's main recommendation. Ju Fufu shares Yixuan's faction. Bangboo: Belion, which gets its full bonus with two Yunkui Summit Agents.

Physical Rupture: Starlight Billy & Dialyn

One of the highest-scoring Lucia teams in the current Deadly Assault. Lucia works the same way with Yidhari, Banyue or Manato in the DPS slot. Bangboo: Birkblick, whose Additional Ability needs at least 3 copies with Dialyn as the only Krampus Agent.

Guide

How to play

Whims, Harmonies and Dream points

Her skills come in two types:

  • Whims: 5th Basic Attack hit, Special Attack, Dodge Counter and Quick Assist.
  • Harmonies: EX Special Attack, Chain Attack, Ultimate and Assist Follow-Up. Harmonies also add a share of her Max HP to their damage.

Outside the Dream state, both types build Dream points (she starts with 60): +40 for the 5th Basic hit, Chain Attack or Assist Follow-Up, +60 for the EX Special, +100 for the Ultimate, +20 for the other Whims. At 100 she enters the Dream state, which triggers a Quick Assist and activates Ether Veil: Wellspring (squad Max HP +5%, 40s, extendable up to 300s).

In the Dream state

  • Her Whims consume 25 points and are upgraded into Harmonies.
  • When she's off-field and an ally hits an enemy, she spends 25 points on a Harmony Aftershock (8s cooldown).
  • Each upgrade or Aftershock gives the squad Dreamer's Nursery Rhyme: +20% DMG for 12s.
  • Every Harmony applies Darkbreaker for 20s: bonus Sheer Force based on her initial Max HP, maxed at 24,000 HP, plus +30% CRIT DMG with a Rupture or Stun teammate (Additional Ability).
  • She leaves the Dream state when she runs out of points or leaves the Veil.

Keeping it all up

  • Her EX Special extends the Veil by 16s and her Ultimate by 32s. Used in the Dream state, the Ultimate also makes her re-enter it right away when it ends, and leaves a healing zone for the active character.
  • Cast an EX Special every ~25s to keep Moonlight Lullaby's +18% DMG up.
  • Opening: tag her in, reach 100 points (from 60, a single 5th Basic hit or EX Special is enough), and she stays in the Dream state for the rest of the fight if you keep extending the Veil.

Casual version: just keep the Dream state and the Veil up and you get most of her value. The optimisation is in timing her EX Specials and Ultimates around your DPS's burst.

Strengths

  • By far the best buffer for Rupture teams: Max HP, Sheer Force, CRIT DMG and DMG in one kit.
  • Easy at a baseline (keep the Dream state up), with room for optimisation.
  • Heals the squad for extra comfort.
  • Her signature isn't required to perform well.

Weaknesses

  • Little to no use outside Rupture teams.
  • Expensive in skill levels to get the most out of her buffs.
  • Her signature is a noticeable upgrade, but only she can use it well since it needs an Ether Veil.

Notable dupes · Mindscape Cinema

M1
Big upgrade

Dreamer's Nursery Rhyme also ignores 18% of All-Attribute RES, and Echo stacks can re-apply it when it ends.

M2
Big upgrade

Harmonies +15% DMG in her Veil, and Darkbreaker Agents gain +15% Sheer DMG. Game8's best stopping point.

M6
Solid upgrade

In any Ether Veil, she gains ATK equal to 2% of her initial HP, and her Harmonies always CRIT with +30% CRIT DMG. Mostly personal damage.
