Quick Answer: Flins is a 5-star Electro Polearm DPS from Nod-Krai featuring Lunar-Charged reactions that can actually CRIT and scale with EM, ATK, and character level. You'll need the Bloodsoaked Ruins weapon, Night of the Sky's Unveiling artifacts, and another Nod-Krai character for Moonsign: Ascendant Gleam activation.
Understanding Flins's Core Mechanics
The Lunar-Charged Revolution
Here's where things get interesting. Lunar-Charged essentially replaces Electro-Charged under specific conditions, creating thunderclouds with completely unique scaling. Unlike those transformative reactions we're all used to, Lunar-Charged can actually CRIT—which changes everything.
The damage formula gets pretty complex: Final DMG = A1 + (A2 / 2) + (A3 / 12) + (A4 / 12), where A1 equals your highest personal Lunar-Charged damage. Personal damage = 1.8 × Level Multiplier × (1 + Lunar-Charged Base DMG Bonus) × (1 + Reaction DMG Bonus + EM DMG Bonus) × (1 + Crit DMG) × Enemy RES Multiplier.
It ignores enemy DEF (nice!) but won't benefit from standard damage percentage buffs. Trade-offs, as always.
Moonsign: Ascendant Gleam
This is non-negotiable. Two Nod-Krai characters activate Ascendant Gleam, providing a 20% Lunar-Charged damage increase through the Symphony of Winter passive. You'll need to pair Flins with either Ineffa or Aino—no exceptions.
Breaking Down Flins's Complete Kit
Elemental Skill: Manifest Flame Form
Ancient Rite: Arcane Light transforms Flins for 10 seconds, converting Normal and Charged Attacks to unoverridable Electro damage. You get interruption resistance too—finally, a character that won't get knocked around constantly.
Northland Spearstorm deals AoE Electro damage and enables a special burst for 6 seconds. Fixed 6-second cooldown keeps things predictable.
The Dual Burst System (This Gets Complicated)
Standard burst Ancient Ritual: Cometh the Night costs 70 energy and delivers AoE Electro damage plus multiple Lunar-Charged instances. Nothing revolutionary there.
But here's the twist: Special burst Thunderous Symphony costs around 30 energy, becomes available 6 seconds after Northland Spearstorm, and delivers one powerful Lunar-Charged instance. Managing both bursts becomes crucial for optimal DPS.
Passive Synergies That Actually Matter
Moonsign Benediction converts Electro-Charged to Lunar-Charged while increasing Base DMG by 0.7% per 100 ATK—maxing at 14% with 2000 ATK. Whispering Flame provides 8% of ATK as EM, capping at 160 EM with 2000 ATK.
These aren't game-breaking, but they add up.
Weapon Selection: Why Signature Matters
Bloodsoaked Ruins (The Clear Winner)
674 base ATK, 22.1% CRIT Rate at level 90. The passive delivers 36% Lunar-Charged damage for 3.5 seconds after Elemental Burst, 28% CRIT DMG for 6 seconds after triggering Lunar-Charged, plus 12 Elemental Energy recovery.
You'll need Nod-Krai materials: Ember/Afterglow/Flare/Blaze of Long Night Flint, Solidified Mist/Mist Plate/Mist Helmet, and Worn/Exquisite/Frosted Certificate. Total cost: 1.2 million Mora.
Alternatives (If You Must)
5-star options include Staff of Scarlet Sands (CRIT Rate + EM-to-ATK conversion), Staff of Homa (reliable stat stick), and Primordial Jade Winged-Spear (consistent scaling). For 4-stars, Deathmatch provides CRIT value while Prospector's Shovel buffs Electro-Charged and Lunar-Charged damage.
Honestly though? The signature weapon gap feels pretty significant here.

Artifact Optimization Strategy
Night of the Sky's Unveiling (Best-in-Slot)
2-piece gives +80 EM. 4-piece Gleaming Moon: Intent grants 15% CRIT Rate (Nascent Gleam) or 30% (Ascendant Gleam) for 4 seconds, plus 10% party Lunar Reaction damage per different Gleaming Moon effect.
The set bonus practically screams build me for Flins.
Backup Options
4-piece Gilded Dreams works for EM/ATK bonuses, while 4-piece Thundering Fury provides Electro DMG and cooldown reduction. Temporary 2-piece combinations: EM (+80), ATK (+18%), or Electro DMG (+15%).
Target Stats (Be Realistic)
Aim for 60-70% CRIT Rate, 180%+ CRIT DMG, 2000-2200+ ATK, and 120-140% ER. Priority order: CRIT Rate/DMG > ATK% > EM > ER.
Main stats: ATK% or EM Sands, ATK% or Electro DMG Goblet, CRIT Rate or DMG Circlet. The flexibility helps with substat optimization.
Team Composition: Building Around Flins
Core Structure (Non-Negotiable)
Flins (On-field DPS) + Off-field Hydro + Second Nod-Krai Character + Flex Support. That second Nod-Krai character isn't optional—it's mandatory for Ascendant Gleam.
Premium Team: Ineffa Synergy
Ineffa provides off-field Electro, energy regeneration, 90% Lunar-Charged damage bonus, and sustain. Rotation: Ineffa E Q → Yelan E Q → Sucrose E Q → Flins E → Normal Attack + Special Burst.
This team feels smooth once you get the timing down.
F2P Alternative: Aino Integration
Aino (free 4-star) serves as both Hydro enabler and second regional character. Rotation: Aino E Q → Fischl E → Sucrose E Q → Flins E.
Not as elegant, but it works.
Anemo Support Considerations
Here's something interesting—Sucrose often outperforms Kazuha due to EM sharing directly amplifying Lunar-Charged damage. Kazuha's Elemental DMG% buffs don't affect Lunar-Charged reactions, which limits his utility here.

Constellation Analysis: Worth the Investment?
C1 reduces Northland Spearstorm cooldown to 4 seconds and provides 8 Energy when party triggers Lunar-Charged (once per 5.5 seconds).
Quality of life improvement.
C2 adds 50% ATK as AoE Lunar-Charged damage to the first Normal Attack after Northland Spearstorm, plus 25% Electro RES reduction for 7 seconds during Ascendant Gleam. Solid damage boost.
C4 provides 20% ATK bonus and enhances Whispering Flame to 10% ATK-to-EM conversion (maximum 220 at 2200 ATK). Nice scaling improvement.
C6 delivers 35% personal Lunar-Charged damage increase and 10% team-wide Lunar-Charged damage during Ascendant Gleam. The big damage spike.
C1 and C2 feel like the sweet spot for most players.
Advanced Optimization Tips
Talent Priority (Don't Overthink This)
Elemental Burst to Level 10 first—it provides your primary Lunar-Charged damage instances. Elemental Skill to Level 10 second. Normal Attack can stay at Level 6 unless you're swimming in resources.
Energy Management Reality Check
The dual burst system requires careful energy planning, but C1 and the signature weapon significantly reduce ER requirements. The special burst's low cost enables flexible rotation adjustments when things go sideways.
Rotation Flexibility
That 6-second skill cooldown and low-cost special burst enable shorter field time and quick-swap scenarios. Makes rotations less punishing than characters requiring long uninterrupted field time—looking at you, Razor.

Release Timeline
Flins is projected for Genshin Impact Version 6.0 Phase I around September 10, 2025. Version 6.0 may introduce additional Lunar reactions and reduce Dendro Core self-damage from 5% to 2%.
Mark your calendars.
