WuWa Mornye Build: Best Echo Set, Weapons & Teams

Greeting Rovers! Mornye arrives in Version 3.0 as a five-star Fusion support who quietly holds your entire team together. This guide will walk you through her best builds, skills, and team comps so you can get the most out of her once she launches.

 

Mornye Overview

Rarity: ★★★★★｜Element: Fusion｜Weapon: Broadblade

Mornye is a calm, analytical support, reflecting her role as a Spacetrek Collective researcher and Startorch Academy professor. In combat, she alternates between her baseline stance and Wide Area Observation Mode, using her Broadblade and drone-like mechanics to heal, buff, and mark enemies.

Mornye Mechanic

Mornye is a Fusion support who alternates between her baseline stance and Wide Area Observation Mode to heal, protect, and boost Break setups. She builds energy to trigger powerful attacks that apply Interfered Marker, enhancing team damage, while her Resonance Skills and Syntony Field provide healing, interruption resistance, and faster Off-Tune buildup.

Observation Marker and Particle Jet improve Break consistency, and her Resonance Liberation delivers a strong Fusion burst with added defensive and healing effects. With damage buffs, steady healing, and a protection effect, Mornye offers a versatile kit that keeps the team safe while accelerating Break windows.

 

Skill Priority

Skill	Priority	Recommended Level
Forte Circuit	★★★★★ (Top Priority)	10
Resonance Liberation	★★★★☆ (High)	9
Resonance Skill	★★★★☆ (High)	9
Intro Skill	★☆☆☆☆ (Low)	1
Normal Attack	★☆☆☆☆ (Low)	1

Mornye’s power budget is heavily concentrated in her Forte Circuit, which directly defines her healing mechanics and overall performance, making it the highest priority to max.

Her Resonance Skill and Resonance Liberation work together as her main sources of healing and utility, and should be leveled evenly right after.

Both Intro Skill and Normal Attack offer limited value and are rarely central to her rotations, so keeping them at level 1 is sufficient for most builds.

Best Weapons

Signature Weapon (Best Choice)
Weapon	Stats (Lv. 90)	Effect (R1)	Notes
Starfield Calibrator (5★)	ATK 413; Energy Regen 77%	Increases DEF by 16%. Casting Resonance Liberation restores 8 points of Concerto Energy. This effect can be triggered 1 time every 20s. When the wielder heals Resonators, increases Crit. DMG of all nearby Resonators in the team by 20% for 4s. Effects of the same name cannot be stacked.	Best-in-Slot. Provides the highest utility for Mornye's specific scaling, though its DEF stat makes it less flexible for other units.
Alternatives
Weapon	Stats (Lv. 90)	Effect (R1)	Notes
Discord (4★)	ATK 338; Energy Regen 51.8%	When Resonance Skill is cast, restores 8 Concerto Energy. This effect can be triggered 1 time(s) every 20s.	Excellent lower-cost alternative. Offers identical Concerto utility to the signature weapon. You only trade off a ~20% Crit DMG buff compared to the signature, but save massive resources; it's the most cost-effective way to fix her ER needs. Highly recommended to push for Rank 5 (R5) to maximize energy gains.
Broadblade #41 (4★)	ATK 413; Energy Regen 32.4%	When the Resonator's HP is above 80%, increases ATK by 12%. When the Resonator's HP is below 40%, gives 5% healing when dealing Basic Attack DMG or Heavy Attack DMG. This effect can be triggered 1 time(s) every 8s.	A solid entry-level "stop-gap" option. Accessible via the Synthesizer, it provides the baseline Energy Regen needed for early-game rotations.
Broadblade of Voyager (3★)	ATK: 300; Energy Regen: 32.4%	When Resonance Skill is cast, restores 8 Resonance Energy. This effect can be triggered 1 time(s) every 20s.	Easy to obtain and craft, helps cover ER needs when higher-tier weapons aren’t available.

Strategy Tips

• The "Niche" Signature: The Starfield Calibrator is a luxury investment. Since its main stat is DEF, it offers no value to traditional DPS characters. Unless you are fully dedicated to Mornye, the 4-star options provide a much better return on investment.
• Prioritize Refinement: For weapons like Discord, hitting Rank 5 is a game-changer. The increased Concerto Energy restoration significantly smooths out your rotation.

 

Best Echo Set

Main Echo	Fallacy of No Return
Echo Set	5-pc Rejuvenating Glow
Cost Pattern	43311

Mornye uses Fallacy of No Return and Rejuvenating Glow because they perfectly boost her support and team damage. Fallacy gives energy regen and a short ATK buff, keeping her skills cycling smoothly, while Rejuvenating Glow turns her healing into a steady team ATK boost. Together, they maximize her uptime and make the whole team hit harder, making her a reliable backbone for Fusion lineups.

Main Echo	Reactor Husk (New)
Echo Set	5-pc Halo of Starry Radiance (New)
Cost Pattern	43311

Mornye comes with a new healing mechanism and a brand-new healer set, though its bonuses currently appear to be identical to those of the previous healer set. She also has extremely high Energy Regan requirements, needing to reach 260%. The new set’s Cost 4 Mian Echo does not provide any supportive utility, so in the early stages, a 33311 setup can be used to compensate for the efficiency shortfall.

Main Stats

Main Stats
4-cost Echoes	Healing Bonus / DEF
3-cost Echoes	Energy Regen / DEF
1-cost Echoes	DEF

Sub-Stats

Energy Regen > DEF% > DEF > CRIT DMG > DMG

Recommended Endgame Stats

To fully optimize Mornye for high-level content, aim for these target benchmarks. Note that reaching the Energy Regen threshold is more important than any other stat.

• ENERGY REGEN: ＞260%
• DEF: 3,800 – 4,000+
• HP: 25,000 – 26,000+
• CRIT RATE: 25% – 30%+
• CRIT DMG: 170% – 180%+

 

Mornye Resonance Chain

S1: The Silent Observer (About 30% DMG increase compared to S0)

Makes her key attacks immune to interruption, allows Interfered Marker even on unmarked targets, links Observation Marker with Interfered Marker, and extends Interfered Marker duration by 150%, enhancing control and team damage potential.

S2: The Entropic Morning Star (About 7% DMG increase compared to S1)

Increases all nearby Resonators’ Off-Tune buildup by 20% and boosts Crit Rate against targets with Interfered Marker, scaling with Mornye’s Energy Regen, improving team burst efficiency.

S3: Blueprint of Recursion (About 8% DMG increase compared to S2)

Casting Distributed Array restores 25 Concerto Energy and all Relative Momentum once every 25s, improving skill uptime and rotation.

S4: Latent Variables of the Cosmos (About 33% DMG increase compared to S3)

Strengthens High Syntony Field healing by 30%, enhancing her sustained support capabilities.

S5: The Clock-Slow Effect (About 27% Healing Ability increase compared to S4)

Boosts the damage of Resonance Liberation – Critical Protocol by 40% and Tune Rupture Response – Particle Jet by 160%, increasing her burst and reactive damage.

S6: Till the Last of Stars (About 250% DMG increase compared to S5)

Resonance Liberation now deals two extra Fusion DMG instances at 400% each, restores 10% of her Max Resonance Energy, and reduces cooldowns after 4s of inactivity, providing powerful burst and faster skill rotation.

Mornye’s Resonance Chains offer distinct advantages depending on team needs. S1 prioritizes versatility and survivability, extending field duration while providing sustained healing and interruption resistance, making it ideal for stable, steady-damage teams.

S2 focuses on boosting damage, granting increased damage amplification and Crit DMG, perfect for high-burst lineups looking to maximize overall team output. S3 accelerates skill rotation and battle tempo by reducing cooldowns and increasing skill uptime, allowing Mornye to trigger her healing and damage buffs more frequently, fitting fast-paced, aggressive teams.

Summary Recommendation

Priority Tier: S0R0 > S1R0 > S2R0

• For the New System: Stop at S0R0 (with a 4-star ER weapon like Discord). She is already a complete unit for the new system.
• For Universal Utility: Aim for S1R0 to make her usable in every possible team composition with zero stress.

 

Team Compositions

Mornye	Lynae	Iuno
Mornye	Lynae	Sanhua
Mornye	Lupa	Galbrena / Brant

Mornye works well with high-burst characters, using her damage amplification and Resonance efficiency to boost overall team output. She is also effective alongside allies who need healing and protection, leveraging her sustained healing and interruption resistance to enhance team survivability.

 

Conclusion

Mornye is a dependable Fusion support who keeps teams safe while boosting their damage and Break consistency, and her long-term value makes her an easy pick if you want a unit who fits into countless teams, scales well, and instantly stabilizes your account.
