Best Echo Sets for Mortefi

Empyrean Anthem
5pc
Empyrean Anthem

★★★ - Best. Empyrean Anthem greatly increases Coordinated Attack damage and buffs the active Resonator's ATK on critical hits. Works best with Mortefi's Liberation; S4 Resonance Chain is recommended to fully utilize the extended Liberation duration.

Moonlit Clouds
5pc
Moonlit Clouds

★★☆ - 2nd Best. Increases Energy Regen and buffs ATK of the next character after Mortefi's Outro Skill, helping reduce downtime for his Liberation and improving follow-up damage.

Moonlit Clouds
2pc
Moonlit Clouds
Molten Rift
2pc
Molten Rift

★☆☆ - 3rd Best. The 2-piece bonuses can be combined to boost Fusion DMG scaling and Energy Regen, helping Mortefi cast his Liberation more often. Use when 5-piece Empyrean Anthem isn't available.

Mortefi's Best Primary Echo

Hecate

Hecate

Provides a significant increase in Coordinated Attack damage which synergizes extremely well with Mortefi's Resonance Liberation. Also deals Havoc damage around Mortefi, adding passive extra damage.

Impermanence Heron

Impermanence Heron

Restores Mortefi's Resonance Energy to let him cast Liberation more often and increases the next character's damage after Mortefi, acting as a semi-support option.

Nightmare: Inferno Rider

Nightmare: Inferno Rider

Good Fusion damage option when using Mortefi as a (primary) DPS. Replace with more support-centric Echoes later in the game; use if you have that Nightmare version available.

Inferno Rider

Inferno Rider

Good Molten Rift option if you don't have the Nightmare version yet (Rinascita unavailable).

Best Tips & Tricks for Mortefi

Aim for ~65%–70% CRIT Rate when running Empyrean Anthem to reliably proc its effects and maximize coordinated attack effectiveness.
Prioritize upgrading Resonance Liberation first, then Forte Circuit, then Resonance Skill/Normal Attack, with Intro Skill last.
Empyrean Anthem (5‑pc) + Hecate is the top Sonata/Echo setup for maximizing Mortefi's off-field coordinated attack damage.
Mortefi's Burning Rhapsody makes him trigger a Marcato on the on-field character's Basic Attacks and two Marcatos on Heavy Attacks—pair him with characters who frequently heavy attack or reliably land hits to maximize coordinated attack uptime.
Energy Regen substats and weapons that restore Concerto/Resonance Energy (Cadenza, Relativistic Jet, Static Mist) reduce downtime for Resonance Liberation and let Mortefi cast more often.
Forte Circuit (Fury Fugue) requires generating Annoyance (up to 100) via Normal Attacks and Intro/Resonance hits; if you plan to play Mortefi on-field, invest in Normal Attack/Resonance Skill levels to speed Annoyance generation.

Best Teams for Mortefi

Aero Heavy Attack Team

Empyrean Anthem is recommended on Mortefi only if he is S4; otherwise use Moonlit Clouds. Team is centered on Heavy Attack buffing and Shorekeeper sustain.

Team goal: buff Jiyan's overall damage by increasing his Heavy Attack DMG via Mortefi while Shorekeeper supplies healing and team buffs., 1) Start with Shorekeeper and charge Resonance Liberation and Concerto Energy until teammates' icons glow., 2) Cast Shorekeeper's Resonance Liberation, then switch to Mortefi via his portrait when available; Shorekeeper's Outro grants defensive bonuses and All-Type DMG Deepen., 3) Attack with Mortefi to build his Resonance Liberation, then activate it to grant coordinated/off-field buffs and switch to Jiyan to boost his Heavy Attack DMG., 4) Use Jiyan's Resonance Liberation to enter Qingloong Mode (turns Basic Attacks and Dodge Counters into Heavy Attacks) to maximize Mortefi's buff., 5) DPS with Jiyan until Concerto Energy is full, swap to Shorekeeper to detonate Stellarealm with her Outro/Intro, then repeat.

Electro Heavy Attack Team

Empyrean Anthem is recommended on Mortefi only if he is S4; otherwise use Moonlit Clouds. Shorekeeper is optimal support for high DMG buffing and healing, but Verina/Baizhi are viable alternatives.

Team goal: use Mortefi to buff Augusta's Heavy Attack damage and provide off-field coordinated damage while Shorekeeper covers healing and team DMG buffs., 1) Begin with Shorekeeper to build Concerto and Resonance Energy; activate Stellarealm then switch to Mortefi with her Outro., 2) Use Mortefi to build and cast his Liberation to grant coordinated attacks to Augusta; use his Echo before switching out to provide buffs., 3) Swap to Augusta, perform Prowess-enhanced Heavy Attacks, use Echo Skill for Electro DMG, stack Ascendancy/Majesty via Resonance sequences, and enter Sworn Allegiance when conditions are met for a high-damage window., 4) During Augusta's Sworn Allegiance, capitalise on the time-stop window to land Sunborne slashes and follow-up skills, then switch to Shorekeeper to detonate Stellarealm and repeat.

Mono Fusion Heavy Attack Team

Empyrean Anthem is recommended on Mortefi only if he is S4; otherwise use Moonlit Clouds. This is a damage-oriented team with no dedicated sustain—requires precise play (dodging/counters).

Team goal: funnel Fusion DMG and Heavy Attack DMG buffs to Galbrena so she benefits from both Fusion scaling and Heavy Attack multipliers., 1) Start with Lupa: cast two Resonance Skills, then Liberation to activate Pack Hunt and Glory; build Wolflame stacks with mid-air/Heavy Attacks and convert to Wolfaith., 2) Use Lupa's Echo to grant Afterflame stacks to Galbrena, then cast Resonance Skill and switch to Mortefi., 3) Mortefi should build Energy and cast Liberation to grant coordinated attacks and use Echo for Afterflame stacks before switching to Galbrena., 4) On-field Galbrena: activate Echo, perform Basic Attacks (6+), cast Resonance Skill when Forte full to enter Demon Hypostasis, use Liberation and additional Basic Attacks to consume Forte for max damage, then switch back to Lupa when Outro is ready and repeat.

Coordinated Attack Team

Empyrean Anthem is recommended on Mortefi only if he is S4; otherwise use Moonlit Clouds. Verina is preferred because she supplies Coordinated Attacks in addition to healing and buffs.

Team goal: enable Jinhsi's Incandescence stacking and amplify her Resonance Skill damage by providing coordinated attacks from Mortefi and Verina., 1) Start with Verina and perform her Support combo ending with Resonance Liberation, then swap to Mortefi., 2) On Jinhsi: cast Overflowing Radiance and a Resonance Skill, complete Basic Attack combo to Stage 4, then use Illuminous Epiphany to enable Unison (off-field swap without consuming Concerto)., 3) Switch to Mortefi: build and cast his Liberation to provide off-field Coordinated Attacks, then switch back to Jinhsi to stack Incandescence and increase Illuminous Epiphany damage., 4) Use Jinhsi's Resonance Liberation when available, then swap to Verina and repeat the rotation until the enemy is defeated.
