Mornye, the 5-star Fusion Broadblade support introduced in version 3.0, has quickly become a cornerstone of the new Tune Break and Rupture meta. As a DEF-scaling healer with exceptional team utility, she provides continuous healing fields, 50% Off-Tune buildup boosts, interruption resistance, and a massive 25% All-Type DMG Amplification Outro Skill that lasts 30 seconds.
Her kit revolves around two modes: Baseline Mode, where she builds Rest Mass Energy for a Heavy Attack transition into Wide Field Observation Mode, and the flight-enabled Observation Mode, which generates a Syntony Field for team healing (every 3 seconds) and Off-Tune acceleration. Her markers (Observation and Interfered) enable up to 40% increased DMG taken by enemies, scaling directly with excess Energy Regen (ER). Her Resonance Liberation further upgrades the field and scales Crit stats with ER over 100% (up to 80% Crit Rate and 160% Crit DMG).
In a patch emphasizing Tune mechanics, Mornye shines as the "Shorekeeper of Rupture teams," pairing perfectly with enablers like Lynae while elevating hypercarries such as Augusta, Jiyan, or Aemeath. But with limited pulls, the big question is: prioritize her dupes (Resonance Chains/Sequences) or her signature weapon, Starfield Calibrator?
Mornye's Signature Weapon: Starfield Calibrator Breakdown

Stats (Level 90): Base ATK 413, ER 77%, DEF% 16% (R1).
Effects (R1):
- DEF +16%.
- Resonance Skill (RS) cast restores 8 Concerto Energy (20s cooldown) - crucial for quick swaps in her rotation.
- Healing increases nearby teammates' Crit DMG by 20% for 4 seconds (non-stacking).
This Broadblade is tailor-made for Mornye. Her kit demands high ER (200-300%+ recommended) to maximize Ult Crit scaling, Interfered Marker potency (0.25% DMG amp per 1% ER over 100%, up to 40%), and field uptime. The 77% ER substat alone pushes her into god-tier territory, often outperforming alternatives by enabling consistent rotations without energy issues.
Alternatives:
| Weapon | Rarity | Key Stat | Why It Works | Drawback |
|---|---|---|---|---|
| Starfield Calibrator | 5★ | ER 77% | Perfect synergy: ER scaling, Concerto, team Crit DMG on heal | Banner-only |
| Discord | 4★ | ER 51.8% | Strong ER + 16 Concerto on RS (better than sig in some calcs) | Lower ER cap |
| Dauntless Evernight | 4★ | DEF 61.6% | F2P DEF/ATK buffs on Intro | No ER |
| Lustrous Razor | 5★ | ER 36.5% | Ult DMG stacks | Less ER than sig |
The signature weapon provides ~20-30% personal/team uplift via ER alone, plus reliable Concerto for her buffer role. F2P players can thrive with Discord, but the sig elevates her to meta-defining.
Resonance Chains (Sequences): Pull Value Analysis

Mornye is S0 viable with a strong baseline, but dupes unlock her full potential, especially marker uptime and team Crit.
| Sequence | Effect Summary | Value Assessment |
|---|---|---|
| S0 | Full kit access: 25% team DMG amp, 40% enemy debuff potential, healing fields | Excellent standalone; rivals S0 Shorekeeper in sustain/buffs. |
| S1: The Silent Observer | Interruption immunity on key skills; Interfered Marker anytime (not just Rupture/Strain); +150% duration; auto-applies on Observation Marker | Highest value dupe. Transforms markers from RNG to guaranteed 40% debuff uptime (1.4x final DMG multiplier). ~6-15% team DPS gain in calcs; essential without Lynae. |
| S2: Morning Star of Entropy | Fields/Markers +20% Off-Tune; team Crit Rate up to 32% on Interfered targets (ER scaling) | Strong team Crit synergy; ~10% DPS if markers consistent. |
| S3: Blueprint of Recursion | Distributed RS: +20-25 Concerto + full Momentum (25s CD) | QoL energy; minor for rotations. |
| S4: Latent Variables | High Syntony healing +30% | Sustain upgrade; low DPS impact. |
| S5: Time Dilation | Ult +40%, Particle Jet +160% | Personal DPS spike. |
| S6: Far Shores | Ult +800% DMG (two hits); OOC ER/CD reduce | Hypercarry enabler; whale territory. |
S1 is the standout: it removes dependency on Lynae for markers, extends debuff to 12s+, and ensures consistency. Community calcs show S1 adding 6-7% team DPS minimum, scaling higher in prolonged fights. S2 compounds this with Crit Rate.
Sequences vs. Weapon: Which Has More Pull Value?

- Weapon Priority: If you lack ER weapons (no Discord R5+), pull it first. The 77% ER unlocks her scaling (Crit, debuffs), Concerto aids teams, and heal Crit DMG procs constantly. Equivalent to ~S1 in accessibility for F2P.
- Sequence Priority: S1 > Weapon for teams relying on Rupture (e.g., Lynae/Aemeath). It guarantees the 40% debuff, which multiplies *all* team DPS by 1.4x. S1 + Discord > S0 + Sig in many scenarios.
- Pull Math: 50/50 banners; guarantee every 80-160 pulls (avg 120). Aim S0 + one extra (S1 or Wep). Whales: S2 + Wep.
| Account Type | Recommendation | Why? |
|---|---|---|
| F2P | S0 + Weapon (or Discord) | ER enables kit; S1 luxury. |
| Low Spender | S0 + S1 | Marker uptime > ER if you have Discord. |
| Mid/High Spender | S0 + S1 + Weapon | Full meta power. |
| Lynae Owner | S1 first | Synergy maximizes Tune Break. |
| No Lynae | Weapon + S1 | Self-sufficient debuffs. |
Final Verdict
Pull Mornye - she's unskippable for 3.x longevity. Weapon edges out for most (ER scarcity), but S1 is king for DPS value. Save ~200 pulls; test Discord first. Pair with Lynae for god-tier Tune teams like Lynae/Augusta/Mornye or Aemeath/Lynae/Mornye.
Best Echoes: 5pc Halo of Starry Radiance (Healing + Off-Tune DMG). Main: DEF% / ER / Crit.
