Mornye Weapon Guide: Best in Slot & Alternatives

Mornye, the analytical five-star Fusion Broadblade user set to debut on January 15, 2026, during Wuthering Waves 3.0, brings a unique blend of healing, damage amplification, and team protection. As a support who alternates between a defensive baseline stance and an offensive Wide Area Observation Mode, her weapon choice is critical for optimizing her complex kit. This guide will analyze her key needs and break down the best weapons to fuel her powerful support capabilities.

 

Understanding Mornye's Needs

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

Choosing the right weapon for Mornye starts with understanding what makes her kit tick. Her effectiveness is built on three pillars:

• Energy Regen is Paramount: Mornye's power is directly tied to her Resonance Liberation, "Critical Protocol." Its damage and critical hit potential scale dramatically with her Energy Regen stat. Furthermore, her "Interfered Marker," which boosts team damage against marked enemies, also gains potency from her Energy Regen. A weapon that provides this stat is a top priority.
• Supporting Her Support Role: A significant portion of Mornye's utility comes from healing and providing damage reduction through her skills and "Syntony Field.". Weapons that enhance her healing effectiveness or provide defensive stats like DEF can make her sustain even more reliable.
• Her gameplay involves frequent use of her Resonance Skill for healing and her Intro Skill to enter her enhanced mode. Weapons that trigger effects or restore energy upon using these skills fit perfectly into her rotation.

Mornye Best Choice

Mornye's signature 5-star Broadblade, Starfield Calibrator, is her undisputed best-in-slot option.

Starfield Calibrator

ATK: 413 | Energy Regen: 77%

Definite Solution

Increases DEF by 16%/20%/24%/28%/32%. Casting Resonance Liberation restores 8/10/12/14/16 points of Concerto Energy. This effect can be triggered 1/1/1/1/1 {Cus:Sap,S=time P=times SapTag=3} every 20/20/20/20/20s. When the wielder heals Resonators, increases Crit. DMG of all nearby Resonators in the team by 20%/25%/30%/35%/40% for 4/4/4/4/4s. Effects of the same name cannot be stacked.

Conclusion

Mornye's strength as a top-tier Fusion support hinges on her weapon's ability to fuel her energy-hungry kit. While her signature "Starfield Calibrator" Broadblade is the definitive best-in-slot, excellent alternatives exist. For most players, Discord stands out as the premier alternative, brilliantly bridging her need for Energy Regen and Ultimate damage.

By selecting a weapon that caters to her need for Energy Regen and skill synergy, you'll unlock Mornye's full potential to heal, protect, and amplify your team's damage on the battlefield.
