2. Best Build

Weapons

BEST IN SLOT

Starfield Calibrator

5-Star | DEF% Substat

Signature weapon. Grants 12% Healing Bonus. Casting Intro Skill gives Starfield Marking (+24% Healing Bonus for 12s). Casting Resonance Skill gives Ethereal Endowment (+24% Healing Bonus for 12s). Perfectly synergizes with her kit.

F2P

Discord

4-Star | DEF% Substat

Best craftable 4-star option. Provides consistent DEF% and good base stats. Easy to obtain and refine for free-to-play players.

F2P

Dauntless Evernight

4-Star | DEF% Substat

Alternative 4-star option. Increases DEF by 4% when healing for 7s, stacking up to 5 times. Good for DEF-focused builds.

Echoes (Sonata Effects)

Best Set: 5-piece Halo of Starry Radiance (increases Fusion DMG)

Alternative: 2-piece Halo of Starry Radiance + 2-piece Lingering Tunes (if substats are better)

Slot	Main Echo	Main Stat Priority
Cost 4	Reactor Husk	Healing Bonus%
Cost 3	Any DEF Echo	DEF%
Cost 3	Any DEF Echo	DEF%
Cost 1	Any Echo	DEF%
Cost 1	Any Echo	DEF%

Substats Priority

Crit Rate% > Crit DMG% > ATK% > Resonance Liberation DMG% > Energy Regen%

Aim for 70-80% Crit Rate before stacking Crit DMG. Reactor Husk (main echo) provides buffs after summoning, so prioritize using it before her burst combo.

3. Skill Analysis

Normal Attack: Syntony Strike Priority: Low

Performs up to 4 consecutive Fusion DMG attacks. The 4th attack deals increased damage. During Syntony State (after Intro Skill or complete Basic Attack chain), her attacks are enhanced and provide healing to the team.

Use this to build up to her enhanced state. The 4-hit combo is important for transitioning into her healing window.

Resonance Skill: Syntony Field Priority: High

Deploys a Syntony Field dealing Fusion DMG and healing allies. Available during Syntony Strike state. Enhanced version after completing Enhanced Basic Attack chain. Consumes Syntony stacks for bonus healing. After use, grants Unison effect, allowing her to trigger Outro Skill without Concerto Energy.

This is her core healing source. The Unison effect enables incredibly quick team rotations - use this, then immediately swap to your next character.

Resonance Liberation: Purge of Harmony Priority: Medium

Invokes the power of Fusion to deal massive AoE Fusion DMG and teamwide healing. This is her burst ability, best used when all buffs are active and she has high Syntony.

Use this during her main healing window, ideally after building up Syntony and with Reactor Husk echo buff active.

Forte Circuit: Syntony System Priority: High

Mornye gains Syntony when party members deal Attribute Damage or Coordinated Attacks (1 stack per second, max 40). She can consume Syntony to enhance her healing. At 40 Syntony, teammates gain Eras in Unity, enhancing their attacks.

The more different attributes in your team, the faster she builds Syntony. This is why she works well with diverse teams.

Intro Skill: Fusion's Halo Priority: Medium

Deals Fusion DMG when switching into Mornye. Triggers her Syntony State, enabling her enhanced healing combo.

Always try to switch to Mornye with Intro Skill active to start her enhanced combo immediately.

Skill Level Priority

Basic Attack > Resonance Skill > Resonance Liberation > Forte Circuit > Intro Skill

4. Team Compositions

Mornye's Forte Circuit benefits from having multiple different attributes in the team. The more diverse your team, the faster she builds stacks.

Best-in-Slot Team

Mornye (Support) Lupa (DPS) Iuno (Sub-DPS)

Lupa provides Main DPS damage. Iuno offers sub-DPS and buffs. This team covers 3 attributes (Fusion/DPS/Sub-DPS) for fast Syntony generation.

High Damage Alternative

Mornye (Support) Changli (DPS) Denia (Sub-DPS)

Changli provides Fusion Main DPS. Denia applies buffs and off-field damage. Strong damage output with good survivability.

F2P Friendly Team

Mornye (Support) Chixia (DPS) Yangyang (Sub-DPS)

Chixia at RC6 provides healing and good damage. Yangyang is a free sub-DPS available to all players. Budget but effective for all content.

Rotation Tips

Start with Support skills (apply buffs/debuffs with Sub-DPS and Support)
Switch to Mornye using Intro Skill to enter enhanced state
Complete Enhanced Basic Attack chain (4 hits)
Use Resonance Skill
Complete another Basic Attack chain
Use Enhanced Resonance Skill (consumes stacks)
Use Resonance Liberation if available
With Unison active, switch to next character immediately
Repeat when Concerto Energy is ready

5. Resonance Chain (Sequence Nodes)

Abyssal Ascension: When casting Basic Attack or Syntony Field, gain 1 stack of Herald of Revival (max 4, lasts 6s). When casting Purge of Harmony, consume all stacks - each stack increases its healing by 20% (up to +80% total).

Chronofrost Repose: Recovers 40 Syntony after being out of combat for 4+ seconds. Triggers once every 4 seconds. Excellent for quick-swap playstyle.

Celestial Incarnate: Gain 12 Syntony and 1 stack of Immortal's Descendancy after Intro Skill. Each stack increases DEF by 25% (max 2 stacks, lasts 20s).

Benevolent Grace: When casting Liberation or Purge of Harmony, all nearby teammates gain +20% DEF Bonus for 20s. Team-wide buff.

Frostfire Illumination: Liberation (Purge of Harmony) Healing Multiplier increased by 120%. Massive healing spike.

Thawing Triumph: Purge of Harmony Healing Multiplier increased by 45%. Syntony consumption bonus increased by 71%. Maximum healing spike.

Worth Pulling?

S1 is the sweet spot for most players (+80% skill damage is huge). S2 is excellent for quick-swap teams. S4 makes her a team buffer. S6 is whale territory but transforms her into the highest DPS in the game.

7. Frequently Asked Questions

Is Mornye worth building without her signature weapon? ▼

Yes. Mornye performs well even without Starfield Calibrator. The 4-star craftable 'Discord' provides about 80-85% of her signature weapon's healing, which is still enough to keep the team alive in all endgame content.

What is the minimum Resonance Chain needed? ▼

S0 is completely viable. S1 provides a massive healing boost. S2 improves her Syntony generation. S4 is excellent for sustained healing. S6 is whale territory but provides the highest healing ceiling.

Should I prioritize DEF% or Healing Bonus? ▼

Aim for a balance with DEF% around 2000+ and Healing Bonus around 40-60%. DEF% scales her healing directly, while Healing Bonus amplifies it. Both are important for optimal performance.

How does Mornye compare to other healers? ▼

Mornye is unique because she scales with DEF, making her easier to build than ATK-scaling healers. She provides interruption resistance and team buffs that other healers don't offer.

What team composition is best for F2P players? ▼

Mornye + Chixia + Yangyang is the best F2P team. All supporting characters are free or farmable, and it covers all content comfortably.
