Genshin Impact 5★ Pyro Claymore Main DPS
As with the main stats, Elemental Mastery is better for Mavuika’s Melt teams than ATK% when not paired with Sucrose. If using an Elemental Mastery Sands, however, ATK% performs similarly while being better elsewhere.
#1
Burst = Skill
Max first
Mavuika’s damage comes from both her Burst’s initial nuke and either her Burst-buffed Flamestrider attacks for on-field Mavuika or Searing Radiance for off-field Mavuika. Since the latter two scale with multipliers contained in her Skill, levelling Burst and Skill are both equally important for Mavuika and should be maximized.
Off-field Mavuika simply uses her Skill to enable her Pyro application and off-field damage. She typically casts her Burst if she has a high amount of Fighting Spirit for its damage and DMG% buff. This is usually every rotation if she has a teammate that also consumes Nightsoul points and every other rotation otherwise.
Start Mavuika’s field time with her Burst and perform one of her on-field combos as needed for the team.
Easy Combo 1
Q CccC J CcccF
These are Standard Melt combos, with the player being able to hold down the Charged Attack for most of its duration. Make sure to wait after the initial Burst hit to regain a Cryo aura.
Advanced Vape Combo
Q 6(CDN1)
A good combo on Vape teams with good Hydro application or enemies with infinite Cryo auras, with the basic input being easily repeatable and enabling a reaction on every Charged Attack. Note that this combo applies Pyro too quickly for a single Melt enabler to keep up on their own.
Advanced Solo Cryo Melt Combo
Q CccF dcF dcF dcF
This is a more advanced Melt combo when Mavuika is paired with Cryo off-fielders able to apply Cryo every 2s (Citlali, Escoffier, Rosaria, Qiqi). It awards the player with a Melt on their first Charged Attack and on every subsequent Final.

This setup is very time, skill and ping-sensitive but is the ceiling for Mavuika’s combos sustainable by a single Cryo off-fielder. On low ping (<50), Citlali can perform a quick Normal Attack to delay the Mavuika swap to better coordinate Cryo app. On higher ping, this is not used.

Advanced Double Cryo Melt Combo
Mav Q [Cdc (tap) Cdc CFdc Cdc (tap) CdCdc C] fdC C
This combo utilizes 2 Cryo units alternating their Cryo application (most commonly Citlali and Escoffier) to perform the Continuous Charged Attack tech multiple times while Melting all important hits.

Mavuika will then use the above combo.
Advanced Overload Combos
Q CDCDCCF DCDCCF DCDCC FDC (Footage shown in this combo button)Q CDC (tap) CDCDCCF DCDCCF DCDCC
The first combo simply uses the CDC tech as much as possible and is probably the most common combos seen in showcases, especially for Overload teams. However, the timing to get her last Final within the duration of her Burst’s buff is extremely tight, and easy to miss even with above average gameplay. This gives room for the second "Hybrid" combo, which shifts more of the damage to a more forgiving time window within Burst's buff. Executing it is relatively simpler, as it only uses one Continuous Charged Attack at the start before spamming CDC as dash cooldown allows. The Hybrid combo is preferred unless the player is confident in having an almost frame perfect execution.

Mona’s extremely high buff volume, especially at C4, makes her a theoretically strong consideration. Especially since Sucrose fits naturally into Mavuika’s teams anyway to enable her all-important Hexerei passive. The issue comes from Mona’s extremely limited Hydro application if not able to flexibly swap on-field to use her Normal attacks. Thankfully, since each Hydro application can allow Mavuika to Vaporize twice, it is possible (albeit difficult) for Mona to work as the reaction enabler. The above combo uses Sucrose Burst every other rotation to allow its Absorption to aid with Hydro application and allow Mavuika to Vaporize more Charged Attacks.

Calling upon her authority over "conflict," Mavuika summons the All-Fire Armaments passed down through the line of human Archons, dealing Nightsoul-aligned Pyro DMG. After using this, Mavuika's Nightsoul points are restored to max value, and she enters the Nightsoul's Blessing state.
All-Fire Armaments Has different forms when Tapped or Held.
Tap "Divine Name Unleashed": The All-Fire Armaments manifest as a Ring of Searing Radiance. The Ring follows the current active character and attacks nearby opponents at intervals, dealing Nightsoul-aligned Pyro DMG.
Hold "Ancient Name Unbound": The All-Fire Armaments manifest as a Flamestrider. In this state, Mavuika can ride the Flamestrider at high speed, or activate its hidden backup propulsion module to temporarily cross various terrain types and glide in mid-air. Mavuika's Normal, Charged, and Plunging Attacks will also be converted to deal Nightsoul-aligned Pyro DMG which cannot be overridden. When sprinting, she also deals Nightsoul-aligned Pyro DMG to opponents along her path.
While in the Nightsoul's Blessing state, Tapping the Elemental Skill can switch the All-Fire Armaments' form. The Armaments will disappear once Mavuika's Nightsoul's Blessing state ends.
Nightsoul's Blessing: Mavuika Continuously consumes Nightsoul points according to the All-Fire Armaments' form. Mavuika's Nightsoul's Blessing state ends once her Nightsoul points are exhausted.
If you told Mavuika that in another world vehicles like the Flamestrider required license plates for identification, that would make her happy too: "Well, mine's the only one that exists here. Guess that means I get to pick whatever plate number I want, huh?"

Let the people's inner voices reach the divine throne in the heavens. Mavuika's Elemental Burst is not reliant on Energy, but instead, on "Fighting Spirit."
Fighting Spirit When Mavuika has at least 50% Fighting Spirit, she can consume it all to unleash her Elemental Burst. Mavuika can obtain Fighting Spirit via the following methods: · When in combat, Nightsoul points consumed by nearby party members are converted to Fighting Spirit. · When nearby party members' Normal Attacks hit opponents, Mavuika gains 1.5 Fighting Spirit. This can trigger once every 0.1s.
After using this, Mavuika gains 10 Nightsoul points and enters the Nightsoul's Blessing state. Riding her Flamestrider high in the air, she uses a powerful Sunfell Slice against opponents on the ground, dealing Nightsoul-aligned AoE Pyro DMG and entering the "Crucible of Death and Life" state.
Crucible of Death and Life During this time, Mavuika's various actions will no longer consume Nightsoul points, and her interruption resistance is increased. Also, the DMG dealt by Sunfell Slice and "Ancient Name Unbound"'s Normal and Charged Attacks is increased based on the amount of Fighting Spirit she has when using the Elemental Burst. Crucible of Death and Life will be canceled when Mavuika leaves the field.
"—But this time, I want to break the cycle and free us from this fate for good."

When a nearby party member triggers a Nightsoul Burst, Mavuika's ATK increases by 30% for 10s.

After using her Elemental Burst, Hour of Burning Skies, every point of Fighting Spirit present when it is used increases the DMG that the current active party member deals by 0.2%. The maximum increase obtainable this way is 40%, and this effect lasts 20s, decaying over this duration until it reaches 0.

After Nightsoul points have been fully depleted, Mavuika will switch to using Phlogiston to maintain the All-Fire Armaments' Flamestrider form. While in an area with Phlogiston Mechanics within Natlan, Nightsoul Transmission: Mavuika can be used. When the current active character is sprinting, climbing, swimming, in movement modes caused by certain Talents, or at a certain height in the air, switching to Mavuika will trigger the following: Mavuika enters the Nightsoul's Blessing state and obtains 50% of her maximum Nightsoul points. Nightsoul Transmission can be triggered once every 10s by your own party.

The party's Nightsoul Transmission CD is decreased by 20%.

C1Mavuika's maximum Nightsoul points are increased to 120, and she gains Fighting Spirit 25% more efficiently. Additionally, she gains 40% ATK for 8s after gaining Fighting Spirit.

C6The All-Fire Armaments from the Elemental Skill The Named Moment receive all-round improvements: · Ring of Searing Radiance: When the Ring's attacks hit opponents, a Flamestrider will crash into the struck opponent, dealing 200% of ATK as Nightsoul-aligned AoE Pyro DMG. · Flamestrider: When Mavuika is riding the Flamestrider, she will also summon a Scorching Ring of Searing Radiance to follow her, which will decrease nearby opponents' DEF by 20% and deal 500% of ATK as Nightsoul-aligned AoE Pyro DMG to nearby opponents once every 3s. Mavuika's terrain-crossing abilities will also be further improved.
