Wuthering Waves · 5★ Resonator
"Astral Mapping" The Spacetrek Collective engineer who looks to the stars
Mornye is an engineer at the Spacetrek Collective's research institute and a professor of Exostrider engineering at Startorch Academy, a scientist who walks step by step toward the stars of her dreams on prosthetic legs. She wields a Broadblade with the Fusion element, but she is not a DPS; she is a healing support. The Syntony Field she sets up in Wide Field Observation Mode heals the team continuously and speeds up Off-Tune buildup by 50%. Her Outro grants the whole team 25% All DMG Amplification for 30 s, and Interfered Marker makes targets take up to 40% more damage depending on her Energy Regen. That is why she is one of the most valuable supports for 3.x teams built around Tune Break.
Mornye is a limited 5★ Resonator; she first arrived in the second phase of version 3.0 with the "Distant May the Starlights Be" banner that opened on January 15, 2026, and she got a rerun in version 3.6. She does not appear on the standard banner, so you can only pull her with Radiant Tides while her banner is active. A 5★ is guaranteed within 80 pulls; your first 5★ has a 50% chance of being the featured character, and if you lose the 50/50, the next 5★ is guaranteed.
2-piece: Healing Bonus + {0}.
5-piece: When healing a Resonator in the team, every {0} of Off-Tune Buildup Rate grants a {1} ATK increase to all Resonators in the team for {3}s, up to {2}. Effects of the same name cannot be stacked.
As Mornye heals the team, the whole team gains up to 25% ATK based on her Off-Tune Buildup Rate; the Syntony Field heals every 3 s, so this bonus almost never drops.
2-piece: Healing Bonus + 10%.
5-piece: Increases the ATK of all party members by 15% for 30s upon healing allies.
If you do not have well-rolled Halo of Starry Radiance Echoes yet, Rejuvenating Glow, which grants the whole team 15% ATK when she heals, is a strong alternative together with the Fallacy of No Return main Echo.
Reactor Husk
Its Echo Skill leaps into the air and brings down a heavy blow that deals Fusion damage; it grants 10% Energy Regen in the main slot, which makes the 260% target easier to reach.
Mornye's real target is 260% Energy Regen: Interfered Marker's 40% damage increase and her Liberation's crit bonuses are fully maxed at that threshold. Use the 4-3-3-1-1 layout; her healing scales with DEF, so stack DEF after ER.
Signature weapon. Its 77% Energy Regen main stat makes the 260% target much easier; it increases DEF by 16%, grants 8 Concerto Energy with the Resonance Skill and gives the whole team 20% Crit. DMG whenever Mornye heals.
The best 4★ option: Its 51.8% Energy Regen main stat and 8 Concerto Energy from the Resonance Skill provide most of the signature weapon's rotation benefits for cheap.
Its 61.6% DEF main stat and the ATK and DEF bonus for 15 s after the Intro Skill boost her healing; a good choice if you can get your Energy Regen from Echoes.
A 4★ Broadblade with a 32.4% Energy Regen main stat; its passive does little for Mornye, but it helps close the ER gap.
A 3★ option with a 38.5% DEF main stat; it heals Mornye a little with the Resonance Skill and is enough for new players.

Totals are calculated from game data: Every ascension stage from 1→90, skills 1→10 and every skill tree node.
In her base mode, she uses a four-hit Fusion combo and a Stamina-consuming Heavy Attack; these attacks and Dodge Counter fill her Forte resource, Rest Mass Energy. In Wide Field Observation Mode, Basic Attack turns into a three-hit series and Dodge Counter becomes a counterattack exclusive to that mode.
Expectation Error heals the whole team and puts Mornye into a Parry stance that reduces the damage she takes by 100%; if she is attacked during it, she responds with Optimal Solution, which Stagnates enemies, and the skill's cooldown is reduced by 2 s. In Wide Field Observation Mode, the skill is replaced by Distributed Array, which heals the team and strikes with Hover Cannons.
With 100 Rest Mass Energy, Heavy Attack - Geopotential Shift launches her into the air and switches her to Wide Field Observation Mode for 30 s; in the process, she sets up a 25-second Syntony Field that heals the team every 3 s and increases Off-Tune Buildup Rate by 50%. Heavy Attack - Inversion, performed with the Relative Momentum gained in this mode, leaves an Observation Marker on the target. When the team deals Tune Break damage to this target, the resulting Interfered Marker makes a target in Tune Rupture or Tune Strain - Interfered take up to 40% more damage from the team (0.25% for every 1% of Energy Regen above 100%).
This Fusion strike gains 0.5% Crit. Rate (up to 80%) and 1% Crit. DMG (up to 160%) for every 1% of Energy Regen above 100%; all bonuses max out at 260% Energy Regen. If a Syntony Field is active, it turns into a 25-second High Syntony Field: Teammates inside gain 20% DEF and the healing multiplier rises by 40%.
Deals Fusion damage on entry and leaps into the air, resets the accumulated Rest Mass Energy and switches directly to Wide Field Observation Mode. Thanks to the Blueprint passive, it also grants 20 Concerto Energy (once every 20 s), which makes it the fastest way into the mode.
All Resonators in the team gain 25% All DMG Amplification for 30 s. The effect applies to the whole team rather than just the next character and lasts a long time, which makes it Mornye's most valuable buff.
Mornye's Energy Regen permanently increases by 10%. The Intro Skill Convergence and the 3rd Basic Attack in Wide Field Observation Mode each grant 20 Concerto Energy (each once every 20 s), which gets the Outro ready very quickly.
Using the Resonance Skill grants the team Proof of Boundedness for 60 s (once every 5 minutes). If the active character takes a hit larger than 30% of their Max HP, the damage is capped at 30% (3 times), and they survive one fatal blow; when the effect ends, they recover HP equal to 150% of Mornye's DEF.
Mornye responds to both Tune Rupture - Interfered and Tune Strain - Interfered: When the team applies Tune Rupture - Interfered to a target, she fires Particle Jet, which counts as Tune Rupture damage (once every 8 s per target). While she is in the team, the Tune Strain - Interfered stack cap on targets increases by 1; she can also perform a Tune Break on a target whose Off-Tune level is full.
Even at S0 she is a fully functional support. If you go for Sequences, S1 is the biggest jump: Interfered Marker increases damage in every situation and lasts longer. S2 adds extra Crit. DMG for the team; S6 turns her Liberation into a serious damage source, but it is not required for her support role.
Interfered Marker's duration is extended by 150%, and it increases damage even if the target is not in an Interfered state; leaving an Observation Marker also applies Interfered Marker directly. Basic Attacks in Wide Field Observation Mode become immune to interruption.
Against targets with Interfered Marker, the whole team gains 0.2% Crit. DMG for every 1% of Energy Regen above 100% (up to 32%). The Off-Tune Buildup Rate bonus of Syntony Fields also increases by another 20%.
Distributed Array additionally grants 25 Concerto Energy and 100 Relative Momentum (once every 25 s), so you reach Heavy Attack - Inversion and the Outro much faster.
The healing of High Syntony Field increases by 30%; a small boost that makes it easier to keep the team alive in tough content.
Critical Protocol's multiplier increases by 40%, and the multiplier of her Tune Rupture response, Particle Jet, by 160%.
Critical Protocol deals 400% more damage; also, after more than 4 s out of combat, her Resonance Energy refills by 10% every 0.2 s.
Aemeath and Lynae in Tune Rupture mode are the duo that benefits most from Mornye's Interfered Marker and her 25% team-wide Outro buff; the Syntony Field also makes Tune Breaks more frequent.
Denia in Tune Strain mode applies Tune Strain - Shifting for Qingxiao and grants Tune Break Boost; as the team's only healer, Mornye both keeps everyone alive and increases their damage.

Mornye is a limited 5★ Resonator and can only be pulled with Radiant Tides while her banner is active. She first arrived in version 3.0 with the "Distant May the Starlights Be" banner and got a rerun in version 3.6.
As of 3.6, the best option is 5-piece Halo of Starry Radiance; as Mornye heals, it gives the whole team up to 25% ATK. Use Reactor Husk, which grants 10% Energy Regen, as your main Echo; Rejuvenating Glow with Fallacy of No Return also does the job as an alternative.
Her signature weapon Starfield Calibrator is the best: 77% Energy Regen, a DEF bonus and 20% Crit. DMG for the team whenever she heals are made for her. On the budget side Discord works, and Dauntless Evernight is a DEF-focused option.
Mornye is one of the most valuable supports for the Tune Break teams of 3.x, but she is not a DPS; her own damage stays limited. Her real strength is healing the team, giving the whole team 25% All DMG Amplification with her Outro and increasing the damage enemies take with Interfered Marker.
One of the strongest teams is the Aemeath + Lynae + Mornye Tune Rupture team. Qingxiao + Denia + Mornye works well for Tune Strain, and Lucy + Rebecca + Mornye for the Hack mechanic.
For Ascension she needs Burning Judgment from Reactor Husk, the local specialty Gemini Spore and the Mech Core series. Her skills use the Carved Crystal series, Mech Cores and the weekly material The Netherworld's Stare from Hecate; the full list with quantities is in the materials section.
