Nightsoul State Mechanics
Nightsoul state is a Natlan-specific combat transformation that reclassifies attack properties and elemental application. Unlike traditional bursts, it fundamentally changes how the game engine processes character actions.
Key Parameters:
- Nightsoul Points limit: 80 points (Mavuika)
- Duration: 7 seconds
- Nightsoul's Blessing: Persistent AoE Pyro damage
- Attacks tracked separately from normal attack inputs
Attack Classification During Nightsoul Mode
The game engine categorizes Mavuika's Nightsoul Burst attacks as Elemental Burst damage, not Normal Attack damage, despite visual similarities. This classification determines which support mechanics trigger.

Why Beidou and Xingqiu Don't Work
Beidou's Stormbreaker Requirements
Beidou's Elemental Burst (Stormbreaker) triggers coordinated attacks when the active character performs Normal or Charged Attacks. The game checks for specific Normal Attack tags on damage instances.
Stormbreaker Mechanics:
- Requires Normal/Charged Attack input tags
- Mavuika's Nightsoul attacks carry Elemental Burst tags instead
- No lightning discharge occurs during Flamestrider mode
- Works normally with Mavuika's standard attack string outside burst
Xingqiu's Rainsword Activation
Xingqiu's Raincutter (Elemental Burst) follows identical trigger conditions to Beidou. Rainswords activate on Normal Attack hits, checking for the same damage classification tags.
Test Results:
- Zero Rainsword procs during Nightsoul Burst

- Hydro application completely absent in Flamestrider mode
- Functions correctly with Mavuika's non-burst attacks
- Guhua Sword: Fatal Rainscreen (Skill) still provides damage reduction
Technical Explanation
The game's damage system uses internal tags:
- Normal Attack Tag: Triggers Beidou, Xingqiu, Fischl C6, Yun Jin buffs
- Elemental Burst Tag: Mavuika's Nightsoul attacks carry this exclusively
- No Dual Tagging: Attacks can't simultaneously count as both types
This isn't a bug—it's intentional design preventing double-dipping on buff mechanics.
Compatible Off-Field Supports
Snapshot-Based Buffs (Work Perfectly)
Bennett (Fantastic Voyage):
- ATK buff snapshots when Mavuika casts burst
- Healing maintains survivability
- Pyro Resonance: +25% ATK
- C6 adds 15% Pyro DMG (if activated)
Sara (Tengu Juurai: Ambush):
- ATK buff applies to entire burst duration
- C6 adds 60% Crit DMG for Electro (use with Overload teams)
- 6-second buff duration covers most of Nightsoul state
Xianyun (Starry Phantasm):
- Plunging Attack DMG bonus applies if using aerial combos
- Healing support
- Works with specific Mavuika tech
Elemental Reaction Supports
Furina (Let the People Rejoice):
- DMG% buff scales with HP fluctuation
- Fanfare stacks persist through Nightsoul state
- Hydro application enables Vaporize (outside Nightsoul attacks)
- Best-in-slot support for Mavuika teams
Yelan (Depth-Clarion Dice):
- DMG% buff increases over time (up to 50%)
- Doesn't require Normal Attack triggers
- Hydro application for reactions
- Superior to Xingqiu for Mavuika specifically
Fischl (Midnight Phantasmagoria):
- Oz attacks independently on timer
- Doesn't require Normal Attack triggers (unlike C6)
- Consistent Electro application for Overload
- A4 passive triggers on Electro reactions
Kazuha (Kazuha Slash):
- Elemental DMG% buff via swirl
- Grouping enhances AoE damage
- 40% elemental DMG bonus (C2)
Shielder/Sustain Options
Zhongli (Planet Befall):
- Universal RES shred: 20%
- Unbreakable shield
- No attack trigger requirements
Layla (Starry Illumination):
- Strong Cryo shield
- Night Stars proc independently
- Budget option
Optimal Team Compositions
Vaporize Nuke Team
Mavuika / Furina / Bennett / Kazuha

- Rotation: Bennett Q → Kazuha Q/E → Furina Q/E → Mavuika Q
- Maximizes single-instance Vaporize on Sunfell Slice (444.8% × 1.5)
- Furina's Fanfare + Bennett ATK + Kazuha DMG% = massive multipliers
- Healing from Bennett/Furina maintains Fanfare stacks
Overload Spam Team
Mavuika / Fischl / Chevreul / Zhongli
- Consistent Overload reactions (Ring of Searing Radiance + Oz)
- Chevreul provides Electro RES shred
- Zhongli shield prevents interruption
- AoE damage from Overload explosions
Mono Pyro Team
Mavuika / Bennett / Xiangling / Kazuha
- Pyro Resonance: +25% ATK
- Kazuha buffs Pyro DMG: 40%+
- Xiangling's Pyronado snapshots Bennett buff
- High energy generation for burst uptime
Budget F2P Team
Mavuika / Xiangling / Bennett / Sucrose
- All 4-star supports (except Mavuika)
- Sucrose provides EM share + VV shred
- Bennett + Xiangling core
- Accessible for new players
Fighting Spirit Generation Strategy
Maximize Fighting Spirit before bursting:
Pre-Burst Setup:
- Use Elemental Skill (Rings of Searing-Flame): Generates 30 points
- Perform 10 Normal Attacks: 10 points each = 100 points
- Teammate Nightsoul Burst consumption: Variable (Natlan characters)
- Total possible: 200 points for max damage
Natlan Character Synergy:
- Xilonen Nightsoul consumption: +45 Fighting Spirit
- Chasca Nightsoul consumption: +45 Fighting Spirit
- Kinich Nightsoul consumption: +45 Fighting Spirit
Pro tip: Rotate through Natlan teammates' abilities before Mavuika's burst to cap Fighting Spirit instantly.
Constellation Impact on Team Building
C1 (Heed My Thundering Call):
- Increases Nightsoul Point limit to 120
- Extends burst duration potential
- Doesn't change support compatibility
C2 (Mow Down the Tasseled Crops):
- Grants 30% Crit Rate during Nightsoul Burst
- Reduces Crit Rate stat requirements
- Allows investment in Crit DMG/ATK substats
C6 (To Cleave the Radiant Clouds):
- Increases Elemental Burst Crit DMG by 100%
- Transforms her into premium DPS
- Prioritize Crit Rate to 70%+ for consistency
Higher cons don't enable Beidou/Xingqiu compatibility but reduce reliance on specific supports.
Weapon Recommendations
Best-in-Slot:
- Redhorn Stonethresher: Crit DMG + DEF-to-ATK conversion (if using charged attacks)
- The Unforged: High ATK% + shield synergy (Zhongli teams)
- Wolf's Gravestone: Team-wide ATK buff
F2P Options:
- Serpent Spine: Crit Rate + stacking DMG% (requires shield)
- Prototype Archaic: Craftable, ATK% substat
- Luxurious Sea-Lord: Free R5, Burst DMG% + ATK buff
Prioritize Crit Rate/DMG and ATK% substats. ER requirements: 120-140% depending on team.
Artifact Sets
Optimal Sets:
- Golden Troupe (4pc): +70% Elemental Burst DMG (if off-field before burst)
- Emblem of Severed Fate (4pc): Burst DMG based on ER (up to 75%)
- Crimson Witch (4pc): +15% Pyro DMG, reaction bonus
Stat Priority:
- Sands: ATK%
- Goblet: Pyro DMG%
- Circlet: Crit Rate/DMG
- Substats: Crit Rate > Crit DMG > ATK% > ER
Target: 70% Crit Rate / 140% Crit DMG minimum (C2 reduces Crit Rate needs).
FAQ
Q: Can any support trigger coordinated attacks during Mavuika's Nightsoul Burst? No. Supports requiring Normal Attack triggers (Beidou, Xingqiu, C6 Fischl, Yun Jin) don't work. Use snapshot buffs or independent proc supports instead.
Q: Does Yelan work better than Xingqiu with Mavuika? Yes. Yelan's DMG% buff doesn't require Normal Attacks and scales over time. Her Hydro application still enables reactions outside Nightsoul attacks.
Q: What's the highest damage rotation? Bennett Q → Kazuha Q → Furina Q/E → Mavuika E → 10 Normal Attacks → Mavuika Q (with 200 Fighting Spirit). Vaporize the Sunfell Slice for peak damage.
Q: Is Mavuika worth pulling without Furina? Yes. Bennett + Kazuha/Sucrose provides strong buffs. Furina optimizes damage but isn't mandatory for viability.
Q: How much does Fighting Spirit affect damage? At 200 points: +320% ATK bonus to Sunfell Slice. This transforms a 444.8% multiplier into effectively 1,869% with max stacks—critical for damage ceiling.
Q: Can I use Mavuika as main DPS outside burst? Her standard attack string works with Beidou/Xingqiu, but damage is significantly lower than Nightsoul Burst. Use her as burst DPS for optimal performance.
