Lucilla is the 5-star Glacio Rectifier who closes out the Lahai-Roi roster in Wuthering Waves 3.4, and she plays as a flexible Sub DPS and support. Her whole kit switches between two states, so the build you target depends entirely on which mode you intend to use her in.
Quick answer: Run Freeze Frame with the Wishes of Quiet Snowfall set and a Glommoth main Echo for Glacio Chafe teams, or swap to the Moonlit Clouds set with an Impermanence Heron main Echo for Echo Skill teams. Prioritize Crit Rate, Crit DMG, Glacio DMG Bonus, and ATK%.
Lucilla’s two Resonance Modes
Lucilla, the president of Startorch Academy, builds Trace through her Basic Attack Stage 3, Resonance Skill, and Intro Skill, then spends 150 Trace to generate three Photos. Casting Resonance Liberation – Clear As Day sends her into Reminiscence, where holding the third stage of her Basic Attack consumes Photos to unleash Oblivion and finish with Letting It Go, her main burst.
The damage type of Letting It Go and Oblivion changes with her active mode, which is what makes her usable in two very different team structures.
| Mode | What it does |
|---|---|
| Resonance Mode – Glacio Chafe | Letting It Go and Oblivion count as Basic Attack DMG. She applies extra Glacio Chafe, shreds Glacio RES, and deepens Glacio Chafe DMG for ice teams. |
| Resonance Mode – Echo | Letting It Go and Oblivion count as Echo Skill DMG. Her first three Oblivion casts register as different-named Echo Skills, and she buffs the team’s Echo Skill DMG. |
Her core nuke, Letting It Go, has interrupt immunity, so her on-field rotation stays smooth even under pressure. The trade-off is that her Concerto cycle runs slightly slower than other Echo supports.
Best weapons for Lucilla
Freeze Frame, her signature Rectifier, is the clear best-in-slot. It gives a flat 12% ATK, and once she inflicts Glacio Chafe, she gains 30% Glacio DMG Bonus while every Resonator on the team gets a 24% ATK boost. Lucilla applies Glacio Chafe herself with ease, so the conditions are trivial to meet.
| Weapon | Base ATK | Stat | Notes |
|---|---|---|---|
| Freeze Frame (5★) | 588 | Crit Rate 24.3% | Signature; team ATK plus personal Glacio DMG Bonus |
| Stringmaster (5★) | 500 | Crit Rate 36.0% | Yinlin’s weapon; strong off-field stat stick |
| Lethean Elegy (5★) | 587 | Crit Rate 24.3% | Phrolova’s weapon; favors Echo Skill output |
| Augment (4★) | 412 | Crit Rate 20.25% | Battle Pass option; Crit-focused budget pick |
| Waltz in Masquerade (4★) | 462 | ATK 18.23% | Craftable; ATK gain against debuffed enemies |
Cosmic Ripples and Rime-Draped Sprouts also work as alternatives if you want a standard banner or Glacio-tuned option instead.
Best Echo sets and main Echoes
Your Echo set follows your chosen mode. Use the 4-3-3-1-1 cost layout for both setups.
Glacio Chafe mode
Equip the five-piece Wishes of Quiet Snowfall set and run Glommoth as the main Echo. The two-piece grants 10% Glacio DMG, and the five-piece adds another 10% Glacio DMG when you apply Glacio Chafe, plus the Snowfall effect. Using Resonance Liberation while Snowfall is active raises Crit Rate by 25%, and casting Outro while it is active hands 25% Glacio DMG Bonus to the next Resonator. Glommoth feeds that same incoming character extra Glacio DMG Bonus after its stomp. Since her damage in this mode counts as Basic Attack DMG, you can lift Basic Attack DMG Bonus higher in your substat rolls.
Echo mode
Switch to the five-piece Moonlit Clouds set with Impermanence Heron as the main Echo. Moonlit Clouds gives 10% Energy Regen and a 22.5% ATK buff to the next Resonator after your Outro Skill. Impermanence Heron restores energy and boosts the incoming character’s damage by 12% when you use the Outro within 15 seconds of the Echo cast, which maximizes your Echo-based main DPS.
Stats to target
| Slot | Main stat |
|---|---|
| Cost 4 | Crit DMG / Crit Rate |
| Cost 3 | Glacio DMG Bonus / ATK% |
| Cost 3 | Glacio DMG Bonus / ATK% |
| Cost 1 | ATK% |
| Cost 1 | ATK% |
Lucilla requires no Resonance Efficiency, so your substat priority is Crit Rate and Crit DMG first, then ATK%, then Basic Attack DMG Bonus for Glacio Chafe builds.
Skill priority
Unlock her inherent skills, Slow Motion and Remembrance, as early as possible. After that, focus your upgrade resources on the skills that drive her rotation and buffs.
- Resonance Liberation (Clear As Day)
- Forte Circuit (Memory Palace)
- Resonance Skill (Phantom Frame)
- Basic Attack
- Intro Skill (Clip It)
If resources are tight, the Resonance Liberation, Forte Circuit, and Resonance Skill trio gives the biggest return, since they control her Trace generation, Photos, and team support.
Best teams for Lucilla
Decide her team before you build her, because her mode dictates her gear. Her cleanest home is the Glacio Chafe team built around Hiyuki, where she adds Glacio RES Shred, Glacio Chafe DMG amplification, and the team ATK buff from Freeze Frame.
| Team | Main DPS | Lucilla mode | Support |
|---|---|---|---|
| Glacio Chafe | Hiyuki | Glacio Chafe | Chisa |
| Echo Skill | Sigrika | Echo | Shorekeeper / Verina |
| Echo (flexible) | Phrolova or Galbrena | Echo | Shorekeeper / Verina |
| Main DPS | Lucilla | Echo or Glacio | Qiuyuan / Sanhua + Shorekeeper |
The Hiyuki, Lucilla, and Chisa lineup is currently the strongest ice team. Note that low-sequence Lucilla is not always a straight upgrade over Lynae in normal Hiyuki teams; she pulls ahead most when Hiyuki is heavily invested, especially at S6 Hiyuki. For Echo teams, Sigrika gets the cleanest value from her, while Phrolova and Galbrena are optional rather than locked-in partners. Verina and Shorekeeper are interchangeable across all of these comps.
Tip: If you invest enough into Lucilla to run her as main DPS, do not force her into a Hiyuki team unless Hiyuki is equally invested, since both characters compete for field priority.
Resonance Chains
| Sequence | Effect |
|---|---|
| S1 – Distant Noon | Auto-fills Perfect Focus on the first hit, grants 20% Crit Rate, and adds interruption immunity. |
| S2 – Slumbering Moonlight | Amplifies Glacio Chafe DMG by 80% or grants 40% Echo Skill DMG Amplification, depending on mode. A major team damage jump. |
| S3 – Days Fade Unheard | Increases the Letting It Go damage multiplier by 100%. |
| S4 – The Past Fades Into Silence | Oblivion pulls targets in, raises Lucilla’s ATK, and reduces damage taken during Basic Attack Stage 3. |
| S5 – Time is Like a Stream | Increases the Oblivion damage multiplier by 50%. |
| S6 – Gazing In the Mist of Time | Stacking Remembrance boosts Letting It Go damage up to 600%, plus out-of-combat Trace restore. |
For pulls, S0R0 (no signature) or S0R1 (with signature) covers her support role. S2R1 maximizes her team support, S3R1 opens up the main DPS playstyle, and S6 is the high-investment ceiling.
Ascension and skill materials
Prefarm these before her banner so you can level her to 90 and max her key skills without delay.
| Category | Materials |
|---|---|
| Ascension | Suncoveter’s Reach, Forget-Me-Not, FF Mech Core, Shell Credit |
| Skill / Forte | We Who Question, Premium Resonance Potion, String, Exoswarm Core |
Suncoveter’s Reach comes from Hyvatia, We Who Question drops from the Denia challenge, and the String and Exoswarm Core counts scale across her four ascension breakpoints.
For most players the takeaway is simple. Slot Freeze Frame and the Snowfall set if you are feeding Hiyuki’s Glacio Chafe damage, or pivot to Moonlit Clouds and Echo mode if you are supporting Sigrika and other Echo Skill carries. Lock in the team first, then gear her to match, and her dual-mode kit will fit cleanly into whichever ice or Echo core you already run.
