How Strong is Mortefi?

Strengths
• Strong DMG buffer for Heavy Attack users. • Provides supplemental DMG through Coordinated Attacks. • Becomes a lot stronger when his Sequence Nodes are unlocked.
Weaknesses
• Needs to be built with Energy Regen stats to consistently use Resonance Liberation. • Resonance Liberation Cooldown is fairly long and tedious to use without Sequence Nodes. • Needs Sequence Node 4 so that Resonance Liberation can be used comfortably.

Mortefi is a great 4-star Sub-DPS who can provide off-field Coordinated Attacks with his Resonance Liberation and buff Heavy Attacks with his Outro Skill. Mortefi becomes especially better the more Sequence Nodes are unlocked.

Mortefi Best Echo Sets

Optimal Main Echo

Main Echo	Explanation
Impermanence Heron	・Restores Mortefi's Resonance Energy so he can cast his Ultimate more. ・Increases the next character's DMG dealt, good for a semi-support role for Mortefi.
Viridblaze Saurian	・A good early game Fusion damage dealer when using Mortefi as a DPS. ・Replace with a support-centric Echo in the later parts of the game.

Echo Tier List

Mortefi Best Sonata Effects

Echo Set	Rating
Moonlit Clouds (5-pc)	★★★ - Best Moonlit Clouds generally increases Mortefi's Energy Regen capabilities as well as increases the ATK of the next character that switches in after Mortefi's Outro Skill. Considering Mortefi's main kit revolves around his Liberation, you'd want this to have as little downtime as possible. Recommended Main Echo: Impermanence Heron
Moonlit Clouds (2-pc) Molten Rift (2-pc)	★★☆ - 2nd Best Molten Rift pieces can also be used since Mortefi deals Fusion DMG. Recommended Main Echo:

Mortefi Best Teams

Mortefi Heavy Attack Team

Main DPS	Sub-DPS	Support
Jiyan	Mortefi	Shorekeeper

This team composition focuses on buffing Jiyan's overall damage in battle using Mortefi's buffs. Mortefi can increase Jiyan's Heavy Attack DMG through his Outro Skill, while Shorekeeper keeps up the team's health and provides buffs through her Resonance Liberation and Outro Skill.

General Rotation

1	Shorekeeper starts the battle and charges both her Resonance Liberation and Concerto Energy until the other Resonator's icons glow.
2	Cast Shorekeeper's Resonance Liberation and switch to Mortefi once his portrait lights up. Shorekeeper's Outro Skill will increase his All-Type DMG Deepen buff and provide passive defensive bonuses.
3	Keep attacking the enemy with Mortefi until his Resonance Liberation is up. Activate Mortefi's Resonance Liberation as soon as you can and then switch to Jiyan to increase the latter's Heavy Attack DMG.
4	Use Jiyan's Resonance Liberation to enter Qingloong Mode. This mode will consider all of his Basic Attacks and Dodge Counters into Heavy Attacks, which will maximize the buff placed on him by Mortefi.
5	Continue to DPS with Jiyan until Concerto Energy is fully charged, then swap back to Shorekeeper to detonate her Stellarealm with her Enhanced Intro Skill.
6	Repeat the steps until the enemy is felled.

Mortefi Coordinated Attack Team (Shorekeeper)

Main DPS	Sub-DPS	Support
Jinhsi	Mortefi	Shorekeeper

This team composition will revolve around Mortefi providing Coordinated Attacks through his Resonance Liberation to support Jinhsi's Incandescence stack, alongisde Shorekeeper's butterflies from her Resonance Skill Coordinated Attack.

General Rotation

1	Use Shorekeeper first and use her Resonance Skill to perform Coordinated Attacks. Cast her Resonance Liberation once available in order to lay down Crit. Rate and Crit. DMG buffs for the party, then swap to Mortefi.
2	Immediately cast Jinhsi's Overflowing Radiance and follow it up with another Resonance Skill attack. Afterward, complete her Basic Attack combo up to Stage 4, then cast Illuminous Epiphany to enable Unison, which allows her to be swapped off-field without consuming Concerto Energy.
3	Switch to Mortefi and perform his optimal combos while charging up his Resonance Liberation. Cast it once available to enable his off-field Coordinated Attacks, then switch back to Jinhsi.
4	Once Jinhsi is back on the field, the main goal would be to stack her Incandesence and increase the damage of her Resonance Skill: Illuminous Epiphany with the help of Mortefi's Coordinated Attacks to maximize its damage output. Be sure to cast her Reesonance Liberation when available.
5	Repeat the steps until the enemy is felled.

Mortefi Coordinated Attack Team (Verina)

Main DPS	Sub-DPS	Support
Jinhsi	Mortefi	Verina

This team composition will revolve around Mortefi providing Coordinated Attacks through his Resonance Liberation to support Jinhsi's Incandescence stack alongside Verina's Coordinated Attacks.

General Rotation

1	Start the battle with Verina and build up her Resonance Liberation plus Concerto Energy. Once both are up, cast her Resonance Liberation first to mark enemies with Photosynthesis, which enables Coordinated Attacks, then swap out to Jinhsi.
2	Jinhsi's ATK will be amplified from Verina's Outro Skill. Once on the field, cast Overflowing Radiance immediately and follow through with another Resonance Skill attack. Use Illuminous Epiphany after Jinhsi's Basic Attack stage 4, which will allow her to swap to the next Resonator without consuming Concerto Energy.
3	Once Mortefi is in the field, build toward his Resonance Liberation and cast it when ready to enable his off-field Coordinated Attacks. Switch to Jinhsi again with full Concerto Energy.
4	The Coordinated Attacks from Mortefi will help stack Jinhsi's Incandesence which will increase her Forte Gauge buildup and enhance the ATK damage of Illuminous Epiphany, which will be her finishing move before swapping to another Resonator. Cast her Resonance Liberation if avilable.
5	Repeat the steps until the enemy is felled.

How to Play Mortefi

Mortefi Gameplay Guide
Cast Enhanced Resonance Skill to Deal More Damage Use Mortefi's Ultimate to Deal Coordinated Attacks

Cast Enhanced Resonance Skill to Deal More Damage

Combo
Res. Skill → BA1 → BA2 → BA3 → BA4 → Resonance Skill: Fury Fugue (consumes 100 “Annoyance”)

When switching into Mortefi and his Ultimate has not yet been charged, do the combo shown above to accumulate Resonance Energy and also deal some damage.

Successfully executing the combo allows Mortefi to use his enhanced Resonance Skill!

Resonance Skill Restores More Annoyance

Using Mortefi's Resonance Skill followed by four Basic Attacks allows him to fill up his Forte Circuit gauge quickly because his Resonance Skill restores more “Annoyance” for 5 seconds.

Use Mortefi's Ultimate to Deal Coordinated Attacks

Mortefi's Ultimate is his most important ability since it makes Coordinated Attacks when switching out to other characters. Basically, Mortefi launches a follow-up attack when a character does a Basic Attack, firing 1 Mercato.

Mortefi also launches a follow-up attack when someone does a Heavy Attack, firing 2 Mercatos!

Outro Skill Buffs Heavy Attack Damage

Mortefi's Outro Skill is amazing since it can have the on-field character's Heavy Attack DMG Amplified by 38% for 14 seconds. His Outro Skill works well with characters such as Jiyan!

Ideally, you want to use Mortefi's Ultimate only when the Concerto Energy is full so his Outro Skill activates!

Mortefi Recommended Combos

Optimal Rotation Combo

Combo
Intro Skill → Res. Skill → Res. Skill: Draconic Hellfire → Basic Attacks → Res. Skill: Draconic Hellfire → Echo → Res. Lib → Outro

Start by using his Intro Skill followed by his Resonance Skill. Afterwards, use the Draconic Hellfire and then use Mortefi's Basic Attacks to fill up Concerto Energy and gather Annoyance for Draconic Hellfire.

After using a second Draconic Hellfire, use Mortefi's Echo. Finish it up by using Mortefi's Resonance Liberation and then switching to the DPS to buff them with his Outro Skill.

If you have Mortefi's Sequence Node 4 unlocked, you can use the Resonance Liberation then his Echo since the former now has a higher uptime than an Echo's buffs.

Mortefi Skill Priority and Forte List

Skill	Priority	Explanation
Normal Attack	★★★☆☆	Basic Attacks will be the main way for Mortefi to generate Annoyance stacks for his Forte Circuit. While it's not the highest priority skill to upgrade, you'd still want to level this up third with how often you'll be using it.
Resonance Skill	★★☆☆☆	His Resonance Skill is also mainly used for Annoyance stacks and its upgrade priority can be swapped with his Basic Attack if you prefer using this over auto-attacking.
Forte Circuit	★★★★☆	When you're using Mortefi as your active character, his Forte Circuit will be the main source of his DPS. Upgrade this after his Resonance Liberation so that he isn't used solely as an Ult bot.
Resonance Liberation	★★★★★	Mortefi's Resonance Liberation is his most important skill, besides his Outro Skill, since it increases the damage output of whatever Basic Attacking Main DPS you switch to. Prioritize upgrading this skill above anything else to maximize the damage it deals.
Intro Skill	★☆☆☆☆	While his Intro Skill isn't bad, it's still the lowest priority upgrade since it's mainly used to generate Mortefi's initial Annoyance charges.

Mortefi's coordinated attack damage comes mostly from his Resonance Liberation, so level that one up first. Afterward, focus on his Forte Circuit for an additional source of damage while following it up with his Resonance Skill.

This makes sure Mortefi can deal as much damage as possible with his off-field attacker role in the current meta.

Mortefi Resonance Chain

Recommended Sequence Nodes

	Why We Recommend It
S1	★★★☆☆ - Good Mortefi's Ultimate is already his best skill, and adding Coordinated Attacks to Resonance Skills, on top of Basic and Heavy Attacks, makes his Resonance Liberation so much stronger. The biggest downside, however, is that your Main DPS needs to use their Resonance Skill a lot, like Danjin or Lingyang.
S2	★★☆☆☆ - Okay This is an okay Sequence Node to unlock since Mortefi's most important skill is his Ultimate. Even though there are other ways to get Resonance Energy, having an extra source of Resonance Energy Regen will allow Mortefi to use equipment that has more offensive stats instead of ones with Energy Regen%.
S3	★★★★☆ - Great Having bonus CRIT DMG on his Ultimate is great since it allows Mortefi to focus on getting equipment with other substats. The only downside is that if his equipment doesn't have a CRIT Rate%, then you won't be able to make use of this upgrade.
S4	★★★★★ - Amazing Mortefi's S4 upgrade is by far the best one to unlock since it will extend his Ult's duration by 7 seconds. This will make the total duration of his Ultimate 17 seconds, leaving you with only a 7-second downtime in between Ult casts. As a note, without this upgrade, it would be 14 seconds of downtime.
S5	★☆☆☆☆ - Bad While this is nice to have, you're mainly using Mortefi to buff up your Main DPS with his Resonance Liberation and Outro Skill. This can make Mortefi a good Main DPS, but he's still better suited for the Sub-DPS role.
S6	★★★★☆ - Great The capstone to his Resonance Chain further improves on his role as a Sub-DPS since you'll be swapping out to your Main DPS every time you use Mortefi's Resonance Liberation. This will boost their ATK on top of the ATK Boosted Coordinated Attacks that they get.

All Sequence Node Effects

S1	Solitary Etude During Resonance Liberation Burning Rhapsody, Mortefi launches Coordinated Attacks when the on-field character performs their Resonance Skills, firing 2 Resonance Liberation's Marcato hits, dealing Fusion Damage.
S2	Hypocritical Hymn After using the Echo Skill, Mortefi restores an additional 10 Resonance Energy. This can be triggered once every 20 seconds.
S3	Flaming Recitativo During Resonance Liberation Burning Rhapsody, the Crit. DMG of Resonance Liberation's Marcato is increased by 30%.
S4	Cathartic Waltz The duration of Resonance Liberation Burning Rhapsody is extended by 7 seconds.
S5	Funerary Quartet When Resonance Skill Fury Fugue hits a target, 4 Resonance Liberation's Marcato hits will be fired, dealing Fusion Damage. DMG of Resonance Liberation's Marcato fired in this way is reduced by 50%.
S6	Apoplectoc Instrumental When Resonance Liberation Violent Finale is cast, ATK of all team members is increased by 20% for 20s.
