Best Echo Sets for Mortefi

Empyrean Anthem
5pc
Empyrean Anthem

5-piece Empyrean Anthem is the best pick. It significantly increases Coordinated Attack damage and buffs the active Resonator's ATK on critical hits — pairs perfectly with Mortefi's off-field coordinated Marcato output. S4 Resonance Chain recommended to fully utilize extended Liberation duration.

Moonlit Clouds
5pc
Moonlit Clouds

5-piece Moonlit Clouds increases Energy Regeneration and can boost the ATK of the next character after Mortefi's outro — helpful to reduce Liberation downtime.

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

Combine the 2-piece bonuses for faster Liberation and Fusion DMG scaling. Good budget option if you can't run a 5-piece Empyrean set.

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 for additional passive damage.

Impermanence Heron

Impermanence Heron

Restores Mortefi's Resonance Energy so he can cast Liberation more often and increases the next character's damage — useful as a semi-support option.

Nightmare: Inferno Rider

Nightmare: Inferno Rider

Good Fusion damage-focused Echo for using Mortefi more as a direct DPS. Swap to a support-centric Echo later in the game.

Inferno Rider

Inferno Rider

A solid Molten Rift option if you don't have access to the Nightmare version (Rinascita).

Best Tips & Tricks for Mortefi

Aim for ~65%–70% CRIT Rate when running Empyrean Anthem to reliably trigger its effects and maximize coordinated damage.
Prioritize Resonance Liberation first when upgrading skills, then Forte Circuit, then Normal/Resonance Skill; Intro Skill is lowest priority.
Static Mist is the best-in-slot for Mortefi as a Sub-DPS because it increases Energy Regen and buffs the incoming character's ATK via Outro interactions.
If you lack Static Mist/The Last Dance, use Cadenza or Relativistic Jet to improve Concerto/Resonance energy regeneration and make rotations smoother.
Use Heavy Attacks on the on-field character while Burning Rhapsody is active — Mortefi launches 2 Marcato on Heavy Attacks, greatly increasing coordinated damage output.
Empyrean Anthem pairs extremely well with Mortefi — ensure you have S4 Resonance Chain (extended Liberation) to fully utilize the set's duration-based benefits.
Moonlit Clouds (5-piece) is the secondary option if you need more energy regen and a buff to the next character; mixing 2-piece Moonlit Clouds + Molten Rift is a budget alternative.
Playtip: time Mortefi's Liberation before switching to your main DPS so they can benefit from sustained Marcato procs; Outro Rage Transposition amplifies Heavy Attack damage of the next character for 14s.

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.
