WuWa Mornye Build Guide: 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.

Her kit accelerates Off‑Tune buildup, provides group healing and interruption resistance, and amplifies team damage, making her a reliable backbone for Fusion-focused teams or any lineup needing stable support.

Mornye Release Date

Mornye is set to debut on December 25, 2025, during the second half of Wuthering Waves Version 3.0.

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
Resonance Skill	★★★★★(top)
Intro Skill	★★★★(high)
Inherent Skill	★★★(high)
Normal Attack	★★(low)
Forte Circuit	★★(low)

Focus on upgrading Mornye’s Resonance Skills, since they’re central to her healing and damage. Her Intro Skill, Convergence, helps her get into Wide Area Observation Mode faster, so it’s worth upgrading a bit to use it more often. Her Inherent Skill, Boundedness, offers strong survivability, making it a top priority to level up and keep the team safer.

Best Weapons

Best Choice
TBA ATK: 413 | Energy Regen: 77%	TBA
Alternatives
Lustrous Razor ATK: 588 | Energy Regen: 36.5%	Stormy Resolution Increases Energy Regen by 12.8%. When Resonance Skill is cast, Resonance Liberation DMG Bonus is increased by 7%, stacking up to 3 times. This effect lasts for 12s.
Discord	Ceaseless Aria When Resonance Skill is cast, restores 8 Concerto Energy. This effect can be triggered 1 time(s) every 20s.

For Mornye, prioritize weapons that boost Resonance Regen, healing, or damage amplification. Weapons with attributes like Resonance Enhancement or Healing Boost synergize with her skills, improving both her support and damage potential. If your team lacks crowd control, consider weapons with control effects, such as slow or stun, to help Mornye better protect allies and create openings for damage.

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.
