Mortefi Guide – Builds, Teams, and How to Play

Rotations

For Mortefi’s rotation, we will only be considering sub-dps rotations and prioritize getting Concerto as quickly as possible.

Sub-DPS Rotation

Rotation with Jiyan and Verina

Rotations should always be taken with a grain of salt. Enemies are NOT sandbags and WILL ATTACK YOU. Several factors such as Parry, Dodge Counters, and being knocked back will affect how you approach the rest of your rotation.

Skill Priority

Sub DPS

1. Resonance Liberation
2. Forte Circuit
3. Resonance Skill
4. Basic Attack
5. Intro Skill 

As a Sub-DPS, Mortefi will want to minimize field time, making his Resonance Liberation his main source of damage. His Forte Circuit should be your next priority, as Skill 2 (Fury Fugue) is tied to this skill.

Main DPS

1. Resonance Liberation
2. Forte Circuit
3. Basic Attack = Resonance Skil
4. Intro Skill 

Most of what was said previously in the sub-dps section still applies here, but Mortefi will now spend more time on-field. This makes his Basic Attacks a slightly more appealing option to raise.

Character Synergies

	Jiyan
	The signature duo that you should consider running if you have Jiyan. With the majority of Jiyan’s damage coming from Heavy Attacks during his ultimate, you essentially double the amount of procs on Mortefi’s Resonance Liberation. On top of this, Mortefi provides a Heavy ATK Deepen, further improving his damage output.
	Buffs
	N/A

	Danjin
	If Danjin is played as a main-dps, Mortefi’s Resonance Liberation gains a few extra hits during her rotation. However, the main reason to have him in the team will be for the Heavy ATK DMG Deepen from his Outro Skill. S1 on Mortefi is an important breakpoint for Danjin, since it allows for additional Marcato procs whenever an ally uses a skill.
	Buffs
	23% Havoc DMG Deepen

	Verina
	Verina synergizes well with all main/sub-dps, and Mortefi is no exception. She provides a team-wide All DMG Deepen and ATK buff. On top of this, Verina’s combos are short and do not take up a lot of field time. Additionally, Verina has no problems running Rejuvenating Glow and Bell, offering the team a good mix of offensive and defensive utility.
	Buffs
	• 15% Team-wide All DMG Deepen • 20% Team-wide ATK buff • Rejuvenating Glow and Bell-Borne Geochelone

	Baizhi
	Baizhi is usually left as an alternative/backup pick, sharing similar buffs with Verina. Baizhi’s Outro only buffs the character currently on-field, which means Mortefi will not receive the buff during his Resonance Liberation when off-field. Additionally, the ATK buff is NOT teamwide and requires your Main DPS to interact with an item.
	Buffs
	• 15% All DMG Deepen • 15% ATK buff • Rejuvenating Glow and Bell-Borne Geochelone

	Jianxin
	Mostly brought into stages that have enemies you want to gather. While this may sound underwhelming, there are stages in ToA that have multiple enemies in the same wave. She has the option of using Originite: Type IV for easy access to Rejuvenating Glow set effect at the cost of her own damage.
	Buffs
	• Gather • Rejuvenating Glow with Originite: Type IV and Bell-Borne Geochelone

Weapons

As of 6/11/2024, Mortefi’s best weapon is Static Mist for its high base ATK, Crit Rate, and Energy Regen while also buffing the next character that switches in. Both Undying Flame and Thunderbolt do the same thing and are perfectly fine 4* alternatives.

Cadenza is a more utility-focused weapon that can either shorten or mess up rotations if you do not pay attention to the extra Concerto Energy Generated.

Weapon Name	Comparison	Notes
Static Mist	R0: 100%	The perfect weapon for Mortefi. It provides everything he needs: ER, high base ATK, and Crit Rate.
Novaburst	R0: 82.26%	On paper this is another decent weapon that increases Mortefi’s ATK up to 12%. However, this requires dodging multiple times mid combo to gain stacks.
Undying Flame	R0: 81.94%	Provides a strong and easy way to activate the Resonance Skill buff that should last longer than most main-dps’ burst windows.
Pistols#26	R0: 79.52%	The stacking ATK buff sounds good on paper, but Mortefi will not get enough field time to build up 2 stacks.
Thunderbolt	R0: 79.37%	Similar to Undying Flame, but requires you to weave in Basic Attacks mid-rotation.
Pistols of Night	R5: 71.80%	Budget alternative
Cadenza	R0: 60.00%	Mostly wasted on Mortefi, he already has a short rotation and doesn’t need the additional Energy Regen.

Echoes

Moonlit Clouds: The perfect set for Mortefi, it provides 10% Energy Regen as its 2pc set effect. This alone fulfills the Energy Regen requirements needed to cast his Resonance Liberation after every rotation. However, the main benefit of this set is its ATK buff for the next Resonator while also running Impermanence Heron.

Molten Rift: Unless you really want to push Mortefi’s damage personal damage output or play as a main-dps, then this set should be avoided. 

Lingering Tunes: The same as Molten Rift, but worse. To put it lightly, Lingering Tunes' entire concept conflicts with Mortefi’s Resonance Liberation. Its 5pc effect will never be active while Mortefi is off-field, which is the majority of his damage. At the very least, LT will provide Mortefi with a 10% ATK buff.

Set Effect	Comparison	Notes
Moonlit Clouds 5pc	100%	Your default pick if you plan on running Mortefi as a sub-dps.
Molten Rift 5pc	108.42%	Don’t do it, please. A more selfish set effect that focuses on buffing Mortefi. This can be considered if you want a main-dps Mortefi.
Lingering Tunes 5pc	91.97%	Once again, don’t do it, please.
Moonlit Clouds + Molten Rift 2pc	99.61	This set combination should be treated as a transition set, rather than something to be used in the endgame.

Active Echo Recommendation

Moonlit Clouds - Impermanence Heron: Your usual support Echo, which should be equipped if Mortefi is running Moonlit Clouds. This provides extra buffs to your main-dps, allowing them to deal more damage.

Molten Rift - Inferno Rider: If you are playing main-dps Mortefi, then Inferno Rider provides a 12% Fusion DMG buff. You can also switch to another character during its 3rd hit. This animation cancel can be important to deal more damage, generate Resonance/Concerto Energy, or avoid attacks.

Lingering Tunes - Mech Abomination: The only notable effects this Echo has on Mortefi are its ATK buff and fast animation. Mortefi cannot take full advantage of the damage dealt by this Echo, as it scales with Electro DMG.
