Lucilla is a 5-star Glacio Rectifier who plays two completely different roles depending on her active resonance mode. In Glacio Chafe mode she stacks the Chafe status and feeds ice teams; in Echo mode she pumps out Echo Skill damage buffs. That split is the whole reason her weapon choice matters, since the stat lines that help one mode are not always the ones that help the other.
Quick answer: Equip Freeze Frame, her signature Rectifier, for either mode. If you do not have it, use Lethean Elegy for Echo mode, Stringmaster or Cosmic Ripples as standard 5-star fallbacks, and Waltz in Masquerade as the craftable free-to-play option for Glacio Chafe.
Lucilla weapon comparison (Wuthering Waves 3.4)
Lucilla’s value comes from ATK, Crit, and either Basic Attack DMG (Glacio Chafe mode) or Echo Skill DMG (Echo mode). Her Resonance Liberation costs no Resonance Energy, so Energy Regen is not needed on her weapon. The table below sorts the strongest picks and what each one is best suited for.
| Weapon | Rarity | Key stats | Best for |
|---|---|---|---|
| Freeze Frame | 5★ (signature) | 588 ATK, 24.3% Crit Rate | Both modes |
| Lethean Elegy | 5★ | 587 ATK, 24.3% Crit Rate | Echo mode |
| Stringmaster | 5★ | 500 ATK, 36% Crit Rate | Either mode |
| Cosmic Ripples | 5★ (standard) | 500 ATK, 53.9% ATK | Glacio Chafe burst |
| Augment | 4★ (Battle Pass) | 412 ATK, 20.25% Crit Rate | Budget all-round |
| Waltz in Masquerade | 4★ (craftable) | 462 ATK, 18.23% ATK | Glacio Chafe (F2P) |
Freeze Frame: Lucilla’s best-in-slot weapon
Freeze Frame is tailored to her kit and works in both resonance modes. It carries a high Base ATK of 588 and 24.3% Crit Rate, then layers on a flat 12% ATK boost from its passive.
The standout effect triggers when Lucilla inflicts Glacio Chafe. She immediately gains 30% Glacio DMG Bonus for 12 seconds, and every Resonator on the team gets a 24% ATK increase for 30 seconds. Because Lucilla applies Chafe through her Intro Skill and her Resonance Skill, the condition is easy to keep up. The team-wide ATK buff is what makes this weapon pull double duty as both a personal damage stick and a support tool.
Best alternatives for Echo mode
When Lucilla is set to Echo mode, her own damage converts to Echo Skill DMG, so weapons that amplify that scaling pull ahead.
Lethean Elegy
Phrolova’s signature Rectifier slots in neatly here. It gives 587 Base ATK, 24.3% Crit Rate, and a 12% ATK boost. After dealing Echo Skill DMG, the wielder gains 32% Resonance Skill DMG Bonus, 32% Echo Skill DMG Amplification, and ignores 8% of the target’s DEF for 12 seconds. That cluster of multipliers directly raises Lucilla’s Echo-mode output.
Stringmaster
Yinlin’s signature weapon is a reliable choice for either mode. It offers a high 36% Crit Rate and a 12% Attribute DMG Bonus, with stacking ATK whenever she deals Resonance Skill DMG and an extra 12% ATK while she is off-field. The off-field bonus suits her support-and-swap rotation.
Standard 5-star option: Cosmic Ripples
Cosmic Ripples is a neutral pickup from the standard banner and a strong stat stick. It provides 500 Base ATK, a large 53.9% ATK substat, and 12.8% Energy Regen. Its passive stacks Basic Attack DMG Bonus up to five times when she hits with Basic Attacks, which feeds her Reminiscence window where she chains enhanced Basic Attacks. The Energy Regen is wasted on her since her Liberation needs no energy, but the raw ATK and Basic Attack scaling still make it useful in Glacio Chafe mode.
4-star and free-to-play weapons
If you are building Lucilla without a 5-star Rectifier, these lower-rarity options keep her rotation functional.
- Augment (Battle Pass): 412 Base ATK and 20.25% Crit Rate. At R5, casting Resonance Liberation raises ATK by 15% for 15 seconds, which lines up with her burst.
- Waltz in Masquerade (craftable): 462 Base ATK and an 18.23% ATK substat. Dealing damage to enemies with Negative Statuses adds 4% ATK per second, up to four stacks. Glacio Chafe counts as a Negative Status, so the passive triggers reliably in that mode.
- Radiant Dawn (Battle Pass): 412 Base ATK and 40.5% Crit DMG. Casting Resonance Skill grants 9% ATK and 9% Basic Attack DMG Bonus for 10 seconds, which helps her Glacio Chafe Basic Attack damage.
- Fusion Accretion: An ATK% substat with a passive that restores Resonance Energy and adds 10% ATK on Resonance Skill, smoothing out rotations.
How to match the weapon to her role
Lucilla’s two modes change which damage type she scales with, so pick the weapon that reinforces the mode you run most.
- Glacio Chafe mode: Her skills convert to Basic Attack DMG. Prioritize ATK, Crit, and Basic Attack DMG. Freeze Frame is ideal, with Cosmic Ripples or Waltz in Masquerade as backups.
- Echo mode: Her damage becomes Echo Skill DMG. Lethean Elegy is the strongest non-signature pick, followed by Stringmaster.
Across every option, skip Energy Regen as a deciding factor. Lucilla’s Resonance Liberation, Clear As Day, consumes no Resonance Energy and unlocks once she holds all three Photos, so offensive stats always win out.
If you are weighing whether to pull her weapon, Freeze Frame is the clean upgrade because it covers both modes and shares its team-wide ATK buff. But Lucilla functions well without it, and Lethean Elegy, Stringmaster, Cosmic Ripples, and the craftable Waltz in Masquerade each cover a specific role at a fraction of the investment.
