Wuthering Waves 3.8 Lily Build Guide! 260% Resonance Efficiency Endgame Stats, Echo Substats

Wanderers, Version 3.8, “Lilies Withering in Old Dreams,” is finally live, and this update has sent expectations through the roof!
As soon as the first-half banner opened, many players probably spent all their saved Astrites. Lily, the five-star Spectro pistol healer and support, is the final piece for the Heart Moon Fox and Suo Ming core. She fits the dual-conductive team perfectly, provides major damage amplification, and completes the Harmony composition.
Pulling Lily is only the first step. Unlike conventional ATK- or HP-stacking healers, Lily has a strict stat requirement: 260% Resonance Efficiency. Below that threshold, her buffs are incomplete; at the threshold, her team contribution changes dramatically. This guide breaks down her mechanics, Echoes, stats, teams, Resonance Chains, weapons, and materials.
Lily’s Core Mechanics: Convert Resonance Efficiency into Team Buffs

Lily is a five-star Spectro pistol character positioned as a short-field survival support. She does not need to deal damage on field for long; bring her in, cast her skills, trigger Outro, and return to the backline.
Her main strength is her Resonance Efficiency stat.
Lily’s inherent skill converts Resonance Efficiency into team buffs. At 260%, she receives the full conversion and unlocks up to 80% Crit Rate and 160% Crit DMG. Reaching 260% should therefore be your first build priority.
Her Outro Skill also provides 25% teamwide all-damage amplification, but damage must be dealt during its duration, so your rotation matters. Dream Fragrance and Silver Dream provide the main DPS with roughly 14% to 28% ATK and grant Echo Skills 10% Crit Rate and 20% Crit DMG.
Because she scales with HP, Lily also offers strong healing, shielding, interruption resistance, and crowd control through her heavy attack.
Recommended rotation:
Intro → Basic Attack 3rd/4th hits → Resonance Skill → hold Basic Attack for Heavy Attack and Dream Bell → finishing Heavy Attack → Echo Skill → Resonance Liberation → Outro.
Important details:
● Use Outro within 6 seconds after the Trace appears, or you will not receive the full buff.
● Do not switch back to Lily within 25 seconds after she leaves, or her Dream Fragrance buffs will be cleared.
Echo and Stat Recommendations
For Heart Moon Fox + Suo Ming + Lily Harmony teams, use the five-piece “Crimson-Dyed Reverie Flower” set to boost Harmony responses.
For Siglika + Chou Yuan/Lorsella Echo teams, use the five-piece “Hidden Radiance” set to strengthen Echo Skill buffs. The old healing set is acceptable as a temporary option.
Without her signature weapon, use 33111 with both Cost 3 Echoes carrying Resonance Efficiency. With the signature weapon, use 31111: one Cost 3 Echo with Efficiency is enough, while the other can use Spectro DMG.
Use Jie Xing Sha as the main Echo because it provides additional Resonance Efficiency.
Stat priority:
Resonance Efficiency (reach 260%) > HP% > Flat HP > Crit DMG > Crit Rate.
Lily already provides substantial Crit bonuses, so Crit Rate can easily overcap. Prioritize Resonance Efficiency and HP, since both her healing and buffs scale with max HP.
Team Compositions: Heart-Suo-Lily Is the Version’s Best Answer

At Sequence 0, Lily is strongly tied to Harmony and Echo teams, so she should be assigned according to the composition.
Team 1: Heart-Suo-Lily Harmony
Main DPS: Heart Moon Fox; sub-DPS: Suo Ming; healer/support: Lily.
Replacing Shorekeeper with Lily raises team strength by around 7% to 8%, improves startup speed, and adds healing, 25% all-damage amplification, ATK buffs, and Crit buffs for Echo Skills.
Team 2: Siglika Echo Team
Siglika + Chou Yuan/Lorsella + Lily. Lily’s Echo Skill Crit buffs perfectly match Siglika’s damage pattern.
Team 3: Jabelina Echo Team
Jabelina + Chou Yuan + Lily. This team works, but the improvement is limited and does not justify pulling Lily specifically for it.
Avoid pairing Lily with Floro. Floro cannot fully benefit from Lily’s buffs, making the combination inefficient.
Resonance Chains and Pull Recommendations

S0: Her kit is complete. Players who already own Heart Moon Fox and Suo Ming can use S0 Lily effectively with either her signature weapon or a four-star alternative.
S1: Improves general use and allows non-specialized teams to receive the full Dream Fragrance ATK buff.
S2: The major breakpoint, granting the entire team 8% Crit Rate and 24% Crit DMG. Stop here if your budget allows.
S3: Faster startup and shorter ramp-up time.
S4: More healing, with low priority.
S5/S6: Increases Lily’s personal damage and offers poor value for a support.
Signature weapon “Lullaby”:
The signature weapon is not mandatory. Its 77% Resonance Efficiency greatly reduces Echo farming pressure, but prioritize Lily and S2 if Astrites are limited. The four-star “Colorful Aria” is a viable replacement.
Budget summary:
S0R0: Reliable within her intended teams.
S1R0: Much better versatility.
S2R0 or S2R1: Best value breakpoint and a complete build.
Full Upgrade Materials
Character level 1 to 90 requires 46 Haivisha Sound Cores, 60 Dream Lily materials, Sound Core drops of 4 low-tier, 12 mid-tier, 12 high-tier, and 20 premium, plus about 1.02 million Shell Credits.
Maxing all skills requires 26 weekly boss materials, 25 low-tier, 28 mid-tier, 55 high-tier, and 67 top-tier Burning Bodies, plus 2.03 million Shell Credits.
The signature weapon requires 6 damaged, 6 worn, 10 defective, and 12 complete Exoskeleton Ornaments; 6 unfinished, 8 tuned, 6 reverberating, and 20 echoing Burners; plus 330,000 Shell Credits.
Total Shell Credit demand is approximately 3.38 million, so prepare in advance.
Need More Resources? Top Up with KARDZ

Version 3.8 has a packed schedule, with Lily followed by more new characters. If you want S2R1, daily Astrite income may not be enough, and stamina, Dream Lily materials, and Shell Credits can also become bottlenecks.

● UID direct top-up with no account password required.

FAQ
Q1: Is topping up through Kardz safe? Will I be banned?
Kardz uses UID direct top-up and does not require your account password. Use legitimate platforms and avoid unauthorized black-card sellers.
Q2: What if I enter the wrong UID?
Virtual products cannot be recalled after delivery. Always verify your UID before ordering and preferably copy and paste it.
Q3: Is there a shortcut for farming Lily’s Echo stats?
There is no true shortcut. Farm Echoes, obtain the signature weapon, or top up stamina. Reach 260% Resonance Efficiency first.
Q4: Is S2 really that valuable?
Yes. Teamwide 8% Crit Rate and 24% Crit DMG are exceptionally rare support bonuses, making S2 the best stopping point for many players.
Q5: How long does a top-up take?
Kardz provides 24-hour automated delivery and customer support. Orders normally arrive within minutes, though updates may cause slight delays.

In summary, Lily is the missing core piece for the Heart Moon Fox and Suo Ming team in Version 3.8. Reach 260% Resonance Efficiency, choose the correct Echo set, use S0 if needed, and aim for S2 for the major power spike.
If resources are short, use Kardz to prepare Astrites and upgrade materials before the banner ends.
