“Critical Protocol” — restores HP across threatened allies while banking Concerto. Level first.
“Mass-Energy Equivalence” — enters Wide Field Observation Mode.
Primary generator / setup tool for Liberation and Forte.
Opens rotations and often refunds Concerto or setup buffs.
Team amp or handoff — important for supports, lower for selfish DPS.
Build Concerto on supports → Intro Mornye → “Resolution” / “Mass-Energy Equivalence” resource loop → “Critical Protocol” dump → “Recursion” or swap as needed.
Refine timings once you learn Concerto breakpoints for your specific team.
CRIT / ATK (signature)
Signature Broadblade tuned to Mornye's kit.
Why it works —Best-in-slot when you own it — pull only if you are committing to Liberation “Critical Protocol” long-term.
CRIT Rate / ATK%
Any well-refined 5★ Broadblade with CRIT or ATK.
Why it works —Flexible premium stand-in while farming signature.
ATK% / Energy Regen
Accessible Broadblade option for early investment.
Why it works —Best F2P path — refine and swap off once a 5★ lands.
Premium Mornye shell: Luuk Herssen is the Dual-DPS / quickswap partner; Denia brings All-DMG amp. Rotation: open Luuk Herssen / Denia for Concerto → Intro Mornye → Liberation / Forte dump.

Mornye is the on-fielder — bank Concerto on Luuk Herssen / Denia, Intro in, then dump Liberation / Forte inside their amp windows.
Luuk Herssen shares field time with Mornye — trade Intro / Outro so both Liberation windows get amp coverage.
Denia grants team-wide All-DMG Amplification — a generalist amp seat that stacks cleanly into Mornye’s Liberation.
Basic Attack Perform up to 4 consecutive attacks, dealing Fusion DMG. Heavy Attack Consume STA to attack the target, dealing Fusion DMG.

Expectation Error Heal all nearby Resonators in the team and enter the Parry state, during which DMG taken is reduced by 100% for a time. Switching to another Resonator ends this state immediately. If attacked while in the Parry state, exit the state and cast Resonance Skill - Optimal Solution. If not attacked while in the Parry state, press Normal Attack to exit the state and cast Basic Attack Stage 2. Optimal Solution Stagnate nearby targets and deal Fusion DMG, reducing the cooldown of Resonance Skill - Expectation Error by 2s. Switching to another Resonator ends the Stagnation effect early. Distributed Array While in Wide Field Observation Mode, Resonance Skill is replaced with Resonance Skill - Distributed Array. Heal all nearby Resonators in the team and summon Hover Cannons to strike the target, dealing Fusion DMG.
Attack the targets within the effective range, dealing Fusion DMG. For every 1% of Mornye's Energy Regen exceeding 100%, this skill gains an additional 0.5% Crit. Rate (up to 80%) and 1% Crit. DMG (up to 160%). When casting this skill, if a Syntony Field is present, remove it and generate a High Syntony Field. Can be performed in mid-air. High Syntony Field - High Syntony Field lasts for 25s. - Increases the DEF of all nearby Resonators in the team within the High Syntony Field by 20%. - Inherits the Syntony Field's boost to resistance to interruption and Off-Tune Buildup Rate. - Inherits the Syntony Field's healing effect and increases the Healing Multiplier by 40%.
Attack the target to deal Fusion DMG, then jump into mid-air, clearing all Rest Mass Energy and entering Wide Field Observation Mode.
Resonators in the team gain 25% All DMG Amplification for 30s.
Mornye can respond to Tune Rupture - Interfered and Tune Strain - Interfered. - Responding to Tune Rupture - Interfered: When any Resonator in the team deals Tune Break DMG and inflicts Tune Rupture - Interfered, Mornye casts Tune Rupture Response - Particle Jet. Each target can be damaged by this skill up to once every 8s. - Responding to Tune Strain - Interfered: Each stack of Tune Strain - Interfered on the target increases Mornye's total DMG against them. Each point of Mornye's Tune Break Boost increases the total DMG by 0.12%. While Mornye is in the team, the max stack limit of Tune Strain - Interfered on a target is increased by 1. Mornye can perform Tune Break against the targets with full Off-Tune Level.
Baseline Mode While in her default Baseline Mode, Mornye gains Rest Mass Energy. Heavy Attack - Geopotential Shift When Rest Mass Energy reaches 100 points, Heavy Attack is replaced with Heavy Attack - Geopotential Shift. Cast Heavy Attack - Geopotential Shift to deal Fusion DMG, considered Heavy Attack DMG. Afterward, Mornye jumps into mid-air, consumes all Rest Mass Energy and enters Wide Field Observation Mode. Wide Field Observation Mode Wide Field Observation Mode lasts for 30s. - Upon entering Wide Field Observation Mode, Mornye generates a Syntony Field. - While in Wide Field Observation Mode, Mornye gains Relative Momentum. - If Relative Momentum is below 100 when holding Normal Attack, perform Basic Attack - Wide Field Observation Mode Stage 1 to 3 in sequence. If Relative Momentum reaches 100 during this time, cast Heavy Attack - Inversion instead. - While moving, Mornye continuously consumes STA. STA cannot be recovered while in Wide Field Observation Mode. - When Dodging with directional input, Mornye starts to fly at speed, which lasts for up to 10s or until STA is depleted or until the Wide Field Observation Mode ends. - When Mornye is hit or launched into mid-air, press Dodge to immediately recover from the attack, which is considered a successful Dodge. This effect can be triggered up to 3 times, which resets when Wide Field Observation Mode ends. - Press Jump and Mornye will slowly descend. Before she lands, Basic Attack - Wide Field Observation Mode, Resonance Skill - Distributed Array, and Heavy Attack - Inversion are unavailable. If Jump is pressed when Mornye runs out of STA, she will exit the Wide Field Observation Mode. She will leave the Wide Field Observation Mode also when she Dodges, Jumps, or performs Mid-air Attacks. Additionally, performing environmental interactions, using Utilities, or switching to another Resonator ends Wide Field Observation Mode. The state also ends when Mornye is no longer airborne. Syntony Field - Syntony Field lasts for 25s. - When the Syntony Field is generated, deal Fusion DMG, considered Resonance Liberation DMG. - Continuously restores HP for nearby active Resonators in the team within the Syntony Field, triggered once every 3s. - Increases the Off-Tune Buildup Rate of all nearby Resonators in the team within the Syntony Field by 50%. - Enhances the resistance to interruption of nearby active Resonators in the team within the Syntony Field. Heavy Attack - Inversion - When Relative Momentum reaches 100 points, Heavy Attack is replaced with Heavy Attack - Inversion. - Consume all Relative Momentum to cast Heavy Attack - Inversion, dealing Fusion DMG, considered Heavy Attack DMG. - Heavy Attack - Inversion inflicts Observation Marker upon the target on hit for 30s. Observation Marker When a Resonator in the team deals Tune Break DMG to a target inflicted with Observation Marker, Mornye inflicts an Interfered Marker on the target for 8s. Interfered Marker Targets affected by Tune Rupture - Interfered or Tune Strain - Interfered take increased DMG from all nearby Resonators in the team. For every 1% of Mornye's Energy Regen exceeding 100%, their DMG is increased by 0.25%, up to 40%. Visual Field When a Resonator in the team defeats a target inflicted with Observation Marker or Interfered Marker, Mornye gains Visual Field for 3s. While in this state, Mornye inflicts Observation Marker on the target hit whenever any Resonator in the team deals damage. Tune Rupture Response - Particle Jet Mornye deals one instance of Fusion DMG to targets in the Tune Rupture - Interfered state within range, considered Tune Rupture DMG. Rest Mass Energy Mornye can hold up to 100 points of Rest Mass Energy. While in Baseline Mode, she gains Rest Mass Energy when performing Basic Attack, Heavy Attack, Dodge Counter, or when Resonance Skill - Optimal Solution hits a target. Relative Momentum Mornye can hold up to 100 points of Relative Momentum. While in Wide Field Observation Mode, she gains Relative Momentum when Basic Attack - Wide Field Observation Mode, Dodge Counter - Wide Field Observation Mode or Resonance Skill - Distributed Array hits the target. Mornye cannot gain Relative Momentum during Heavy Attack - Inversion.
Mornye's Energy Regen is increased by 10%. Casting Intro Skill - Convergence restores 20 points of Concerto Energy, triggered once every 20s. Casting Basic Attack - Wide Field Observation Mode Stage 3 restores 20 points of Concerto Energy, triggered once every 20s.
Casting Resonance Skill - Expectation Error or Resonance Skill - Distributed Array grants Proof of Boundedness to all Resonators in the team: - Proof of Boundedness lasts for 60s and can be gained once every 5 min. - When the active Resonator takes DMG greater than 30% of their Max HP, they instead take DMG equal to 30% of their Max HP. This effect can trigger up to 3 times. Proof of Boundedness is removed after triggering it 3 times. - When the active Resonator takes a fatal blow, they are not downed by this instance of damage. This effect can trigger up to 1 times. Proof of Boundedness is removed after triggering it 1 times. - When Proof of Boundedness is removed, the active Resonator restores HP equal to 150% of Mornye's DEF.
Has a chance to produce special dishes when cooking.
Basic Attack – Wide Field Observation Mode becomes immune to interruption. The duration of Interfered Marker is extended by 150%. Interfered Marker now grants DMG increase even when the target is not affected by Tune Rupture - Interfered or Tune Strain - Interfered. When Mornye applies Observation Marker on a target, she also inflicts Interfered Marker.

Is it worth getting?
Late luxury: Adds RES / DEF shred or a large DMG Bonus clause. Grab it if you overshoot toward S6 — never hard-pity for S5 alone.
Resonance Liberation - Critical Protocol deals 400% more DMG. If Mornye has not engaged in combat for over 4s, she restores Resonance Energy equal to 10% of her Max Resonance Energy every 0.2s.
Is it worth getting?
Whale ceiling: Refunds Energy / Concerto / Forte resources mid-rotation. Only chase if Mornye is your dedicated main and S0–S2 already feel finished.
Mornye is fully usable at S0. Most dedicated mains stop at S2 before chasing higher Wavebands. First stop: S2. Endgame target: S2.
