Review

Pros & Cons
Pros

  • Incredibly fast Concerto rotation allowing fast access to his Outro

  • Incredible synergy with Heavy Attackers, boosting them and himself tremendously

  • Good personal damage considering the suite of buffs he provides

  • Insane Sequences that make him even stronger

  • Easy to understand and play even at the highest level

  • Strong enough to be played as a Hybrid even outside of his Heavy Attacker niche

Cons

  • Long Ultimate cooldown - 20 seconds compared to 10 second duration of the buff - so you need to keep this in mind while doing your rotations

  • If you're stuck at S0, looking at the overpowered Sequences will make you feel bad

Review

Mortefi is a 4-star Fusion Pistol wielding Hybrid that can dish out good damage when built correctly, but truly shines in a more Supportive role with teammates that primarily deal Heavy Attack damage. This is because his Ultimate Skill synergises with Heavy Attacks and his Outro amplies them by a further 38%.

Mortefi recharges his Forte Gauge with Basic Attacks, Resonance Skill and Intro Skill, which when full will convert his skill to Fury Fugue. This is similar to his Resonance Skill, being an excellent generator of Concerto Energy and Resonance Energy, with the addition of Fusion DMG in an AoE radius. His Forte Gauge can be quickly filled by using his Basic Attacks after Resonance Skill, unlocking Fury Fugue faster. Another great point of Fury Fugue is that it lacks any CD; it can be spammed indefinitely as long as your Forte Gauge fills up, and it doesn’t interfere with his normal Resonance Skill, allowing him to use the two in quick succession.

His Resonance Skill generates a good amount of Concerto Energy and Resonance Energy while dealing Fusion Damage to his primary target.

His Ultimate Skill deals Fusion Damage in front of him, generating a good chunk of Concerto Energy and buffing the entire team with Burning Rhapsody. While the buff is active, Mortefi will launch a coordinated attack when an enemy is hit by an ally, up to once every 0.35 seconds. If the landed attack is a Heavy Attack, he instead deals 2 coordinated attacks, doubling his potential damage output, making Heavy Attackers his ideal partners.

Mortefi requires minimal field time thanks to having one of the fastest and easiest to execute Concerto rotations in the game, which combines his excellent Outro buff, solid DPS and highly synergistic Ultimate Skill. He is also easy to play as his rotation is simple and fast to execute, making him a good choice for players of all skill. Even if you happen to mess up his rotation, it is quite easy to recover.

While being able to deal good damage as far as Hybrid characters go, his true calling is being a Support thanks to his Outro Skill, hence he prefers the combination of 5P Moonlit Clouds and Impermanence Heron Echo. This stacks an additional 12% DMG and 22% ATK on top of his already potent 38% Heavy Attack amplification from Outro, generating a massive buff stack for the character switching in.

Overall, Mortefi is currently one of the top Hybrid characters in endgame, especially for characters/teams centered around Heavy Attack burst rotation. Even if not for that, he sees use thanks to his incredibly fast Concerto Rotation and synergy with the 5P Moonlit Clouds and Impermanence Heron Echo. His strong Sequences can further increase his utility to your team.

Ratings

This tier list assesses characters based on their combat potential in Wuthering Waves current most demanding content Tower of Adversity (ToA). ToA is a mode similar to Genshin Impact’s Spiral Abyss or Honkai Star Rail’s Memory of Chaos and requires multiple teams, strong Echoes and good Weapons. This mode offers a reasonable mix of Boss encounters (single target), Elite packs (2-3 targets) and AoE scenarios (5+ Targets), allowing multiple characters to find a niche but in the end, there's a bias toward single target focused characters at the top-end.

Please keep in mind Wuthering Waves is a skill-based game and each character has a different playstyle, difficulty level and even special tricks and combos. Wuthering Waves is also a team based game and it's only by combining both these factors to the highest level a character can reach optimal performance.

Best Weapons

100%

Stats at Level 90: ATK: 587 | CRIT Rate: 24.3%

Incredibly potent option offering main stat CRIT RATE, great base damage and a good amount of energy recharge allowing for sub stats to be used elsewhere. Also offers a supportive ability granting the next character to switch in an ATK boost granting it extra value for Hybrid and Support characters.

106.12%

Stats at Level 90: ATK: 500 | CRIT DMG: 72%

Carlotta's Signature and a solid choice for most pistol based resonators due to its decent base damage, very high CRIT DM% and permanent ATK% boost. Far more effective though for resonators that deal some or the majority of their damage through Resonance Skill damaging abilites.

83.92%

Stats at Level 90: ATK: 462 | ATK: 18.2%

While in competition with other F2P 4* options, the buff uptime on this weapon is one of the most consistent and reliable for ATK scaling pistol DPS characters. The ATK% boost it provides when casting your Resonance Skill is great on most characters, and while the small energy generation it provides at the same time is more situational, it can be handy as well.

83.64%

Stats at Level 90: ATK: 412 | ATK: 30.3%

Gun usable by all resonators, offering good bonuses to ATK but reliant on dodging 3 times initially (with continual dodges after that). Should only be used by those willing to perform dodges at the start of their rotation and consistently after. Calculations assume you perform dodges as soon as possible and maintain the buff.

83.07%

Stats at Level 90: ATK: 387 | ATK: 36.4%

Powerful Gun option for Resonance Skill focused damage characters, but with a heavy conditional required for activation. Grants solid base damage and ATK% via main stats. Also offers an incredibly potent stackable Resonance Skill DMG% bonus that requires the users consistently use Basic Attacks to maintain.

82.65%

Stats at Level 90: ATK: 387 | ATK: 36.4%

Generic gun option usable by all characters but with a significant ramp-up time on its bonus. Also requires the player not to be hit in order to extract full value. If you do get hit this weapon will fall behind (calculations assume you don't get hit once).

81.87%

Stats at Level 90: ATK: 412 | ATK: 30.3%

Strong gun option for resonators that deal primarily Resonance Skill DMG with little to no conditions to worry about, thanks to its effect being tied to Intro skills. Grants a Resonance Skill DMG bonus that lasts for 15 seconds on using Intro - long enough for most Main DPS to finish their burst window making this a strong consistent option.
Best Echo Sets

Best Echo Sets show the best sets that support the main character playstyle and work out of the box while the Special Echo Sets either are situational, support an alternative playstyle or are targeted toward min-maxers. The percentage numbers showcase the relative DPS increase when you take into account the set bonus only. For some characters there's no DPS (or its equivalent) available and in that case we listed the sets in the order of priority.

Important! The 2.0 introduced quite a lot of new Echoes and we need more time to properly test out all of them (especially considering the past bugs related to them that made some stronger, some weaker). The builds below are provisional and we will be updating them over the next few days as we do our testing - so before you use all your stamina on the new Echoes, please have a bit of patience.

Best Echo Sets

100%

2 Set: Energy Regen increases by 10%.

5 Set: Upon using Outro Skill, ATK of the next Resonator increases by 22.5% for 15s.

Offers a 10% unconditional Energy Regen% boost taking some pressure off your gear when aiming at ER breakpoints. Also upon using Outro, grants the next character switching in a 22.5% ATK boost, amplifying any of your main damage dealers burst windows.

Below you can find Main Echo options that you should be using with the set:

  • Echo Image
    Impermanence Heron
    - Supportive Echo that can be run at the cost of a sizeable chunk of damage for the character who equips, trading personal gain for team benefits. Should always be used and immediately switch cancelled right before performing an Outro, leading to another DPS. When done so will grant the next character switching in 12% increased DMG% which when combined with the 5P Moonlit set which also grants 22.5% ATK% under the same conditions makes for a sizeable boost. While the echo does lower the damage of whoever wears it, it grants a massive chunk of energy on use usually saving 1 or sometimes even 2 Energy Regen sub stats that may otherwise be needed by the wearer allowing for some damage to be recovered.
Special Echo Sets

2 Set: Energy Regen +10%.

5 Set: Increase the Resonator's Coordinated Attack DMG by 80%. Upon a critical hit of Coordinated Attack, increase the active Resonator's ATK by 20% for 4s.

Offers an unconditional 10% Energy Regen% and 80% Coordinated DMG boost. Also grants a passive supportive effect which triggers when the wearer of this set critically strikes with a Coordinated attack - this effect grants the on field Resonator an ATK% boost regardless if they're the wearer of the set or not.

Below you can find Main Echo options that you should be using with the set:

  • Sentry Construct
    Hecate
    - Offers a 40% unconditional Coordinated Attack DMG% boost when placed in the Main Echo slot, making it a solid choice for Coordinated Attack-focused resonators looking to use the 5P Empyrean Anthem Echo set bonus.

Rotation

Below you can find optimal rotation (or rotations) for Mortefi. The total time needed to perform it is 5.62 seconds. When selecting the rotations we prioritized achieving 100 Concerto as fast as possible and once that condition was fulfilled, we focused on maximizing the damage output. As or if new and more optimal rotations are found, we'll update the characters calculations as needed.


Mortefi is easy and straightforward to play when following the rotation below, however keep an eye out for the following things while playing him:

  • Mortefi’s Ultimate and Outro should be always used together right before you Swap to another character to perform their burst combo (preferably a Heavy attacker). Triggering his Ultimate too early or during his own rotation wastes a chunk of his damage potential as well as buffing potential if S6.
  • Using Resonance Skill: Passionate Variation gains you additional Annoyance from all Basic Attacks for 5 seconds.Taking advantage of this window is important to allow you regain access to Fury Fugue quickly to complete his Concerto and keep rotation short.
  • His Ultimate will be always used at the end of his Concerto Rotation, and generates 20 Concerto Energy (a little less than a quarter of the gauge). As such, plan around this and use his Ultimate when you are missing approx 20 Concerto so as to minimize time spent generating it.

Additional information

The numbers below show the character's DPS (Damage Per Second) and DMG (total damage done). When selecting the rotations we prioritized achieving 100 Concerto as fast as possible and once that condition was fulfilled, we focused on maximizing the damage output. As or if new and more optimal rotations are found, we'll update the characters calculations as needed. Listed character calculations are done without buffs or any damage contribution from teammates (full solo). They only include what the character, their Weapon, Echo and gear are capable of during their ideal Burst or Concerto rotation when starting with their Intro and Resonance Liberation available.

Do note that DPS and DMG aren’t perfect metrics for a character’s individual value and should be taken with a grain of salt.Anything pertaining a character’s relevance in the meta is addressed in our Review and Tier List, which the numbers below shouldn’t be used for as an end-all-be-all to. Instead, DPS and DMG are good metrics for a character’s sequence value and comparison between an individual character’s different rotations. We recommend using those metrics for such purposes.

Rotation time: 5.62s

Details about the calculations

Disclaimer: Mortefi does more damage depending on who he is supporting due to how his ultimate works. His ultimate can fire a maximum amount of 60 coordinated attacks at S0 in a literal perfect world when being abused by a Heavy Attack spammer, but this is not realistic, so we've used 35 coordinated attacks instead. This is how many you could expect to get when using Jiyan. Mortefi's S1 doesn't scale particularly well with Jiyan which is how we've represented but works much much better with characters like Danjin compared to what is shown here.

Here's the rotation we have used to calculate the DPS (Damage Per Second) shown above.
