Mortefi
Dragon's Breath
Free—Mortefi is the standard Heavy Attack amp Sub DPS. Liberation “Violent Finale” applies Burning Rhapsody so teammates trigger off-field coordinated hits. Best with Jiyan / Iuno / Any Heavy Attack carry. Burning Rhapsody coordinated hits only pay if the on-fielder Heavy Attacks during the window. Skip when you never field Heavy Attack carries (still keep him built as a flexible amp).
Mortefi is a 4★ Fusion Sub DPS who fights with a Pistols. Liberation “Violent Finale” applies Burning Rhapsody so teammates trigger off-field coordinated hits. Forte “Fury Fugue” banks Annoyance into an enhanced Resonance Skill dump. Outro “Rage Transposition” hands the next Resonator a Heavy/Basic Attack Amplification window.

Strengths
- Liberation “Violent Finale” applies Burning Rhapsody so teammates trigger off-field coordinated hits — that window is where Mortefi’s clear speed actually shows up.
- Forte “Fury Fugue” banks Annoyance into an enhanced Resonance Skill dump, so resource banking is mandatory, not optional filler.
- Outro “Rage Transposition” hands the next Resonator a Heavy/Basic Attack Amplification window — swap timing is part of the damage plan, not just Concerto filling.
- Skill “Passionate Variation” seeds coordinated pressure so Mortefi still contributes after leaving the field.
Weaknesses
- Needs a real on-fielder to cash out coordinated / Off-field hits — Mortefi is not a full clear unit alone.
- Energy and Forte “Fury Fugue” tuning feel awkward until Concerto breakpoints are learned.
- 4★ ceiling is real — expect to rotate them out when a premium option takes the same niche.

Annoyance Mortefi can hold up to 100 Annoyance and can restore Annoyance in the following ways: - When Normal Attack Impromptu Show hits the target - When Intro Skill Dissonance hits the target - When Resonance Skill Passionate Variation hits the target - Within 5s after casting Passionate Variation, Normal Attack Impromptu Show that hits the target restores Annoyance additionally.

Is it worth getting?
Small 4★ bump: More coordinated-attack damage or trigger frequency. Take Wavebands when they appear on rate-up; never the reason you pull the banner.
After using the Echo Skill, Mortefi restores an additional 10 Resonance Energy. This can be triggered once every 20 second.
Is it worth getting?
Meaningful upgrade: Refunds Energy / Concerto / Forte resources mid-rotation. Strong when it lands, but weigh it against a new limited teammate.
During Resonance Liberation Burning Rhapsody, the Crit. DMG of Resonance Liberation's Marcato is increased by 30%.
Is it worth getting?
Situational S3: Flat CRIT bump tied to a specific combat state.
The duration of Resonance Liberation Burning Rhapsody is extended by 7s.
Is it worth getting?
Side-grade: Extends or empowers the unit’s named burst state. Happy if it drops; not a planned stopping point.
When Resonance Skill Passionate Variation or Resonance Skill Fury Fugue hits a target, Coordinated Attacks will be triggered to fire 4 Resonance Liberation's Marcato hit(s), dealing Fusion Damage. DMG of Resonance Liberation's Marcato fired in this way is reduced by 50%.
Is it worth getting?
Late luxury: More coordinated-attack damage or trigger frequency. Grab it if you overshoot toward S6 — never hard-pity for S5 alone.
When Resonance Liberation Violent Finale is cast, ATK of all team members is increased by 20% for 20s.
Is it worth getting?
Whale ceiling: Raises party ATK from a Stellarealm / team aura. Only chase if Mortefi is your dedicated main and S0–S2 already feel finished.
Mortefi is designed to work at S0. Extra Sequences are comfort from rate-up dupes, not requirements.
