Flins Build Guide 2026: Best Weapons, Artifacts & Teams

Who is Flins and What is Their Playstyle?

Flins is an on-field Electro carry built around Lunar-Charged reactions and repeated Burst access. Instead of pressing Skill and staying in one long infusion window, he moves through a short chain that changes both his Elemental Skill and Elemental Burst. Using Ancient Rite: Arcane Light puts him into Manifest Flame for 10 seconds, converts his Normal and Charged Attacks to Electro DMG that cannot be overridden, increases interruption resistance, and replaces his Skill with Northland Spearstorm.

Northland Spearstorm is the real trigger for the burst window. After using it, the standard Elemental Burst is replaced by Thunderous Symphony for six seconds. This special Burst costs only 30 Energy, compared with the normal Burst's 80 Energy cost. The core playstyle is therefore less about a long hyper-carry Normal Attack string and more about moving quickly through Skill → special Skill → special Burst.

Why is ATK so important for Flins?

ATK does more than raise standard skill multipliers. Whispering Flame converts 8% of his ATK into Elemental Mastery, up to a maximum increase of 160 EM. Moonsign Benediction: Old World Secrets also increases Lunar-Charged Base DMG by 0.7% for every 100 ATK, up to a maximum of 14%. A strong ATK build therefore improves both personal scaling and the reaction system at the center of his kit.

He also raises the party's Moonsign by one level. This matters for his own Ascendant Gleam effects and for the artifact set recommended later in this guide. Players comparing the wider family of Lunar-reaction characters can also read the Linnea build guide; Linnea focuses on Lunar-Crystallize rather than Lunar-Charged, so the two characters represent different Lunar team archetypes rather than a direct team pairing.

What does Moonsign: Ascendant Gleam do for him?

Several parts of the kit become stronger under Moonsign: Ascendant Gleam. His passive Symphony of Winter causes Lunar-Charged reactions triggered by him to deal an additional 20% DMG. The full Elemental Burst can also gain two extra middle-phase Lunar-Charged hits when thunderclouds are nearby, while Thunderous Symphony gains one additional Lunar-Charged hit under the same condition. This is why his best teams are built around Lunar-Charged and Moonsign rather than being generic Electro lineups.

How Do Flins's Skills Work?

Normal Attack: Pocztowy Demonspear

His Normal Attack string contains five spear strikes. At Talent Level 10, the final hit reaches 151.8%, while the Charged Attack deals 203.7% damage and costs 25 Stamina. These attacks are not the main reason to build him, since Manifest Flame has its own enhanced multipliers and the Burst system carries much more of the important Lunar-Charged damage.

Elemental Skill: Ancient Rite: Arcane Light

Using Ancient Rite: Arcane Light activates Manifest Flame for 10 seconds. During this state, Normal and Charged Attacks become Electro DMG and cannot be overridden by another infusion. He also gains increased interruption resistance but loses access to Plunging Attacks. Most importantly, the normal Skill button becomes Northland Spearstorm.

What does Northland Spearstorm do?

Northland Spearstorm summons a group of spears in front of the character and deals 321.1% AoE Electro DMG at Talent Level 10. Its base cooldown is 6 seconds, and the supplied skill data states that this cooldown cannot be affected by other effects. Casting it changes Ancient Ritual: Cometh the Night into Thunderous Symphony for the next six seconds.

Elemental Burst: Ancient Ritual: Cometh the Night

The normal Burst deals several stages of AoE Electro damage, with its later hits treated as Lunar-Charged DMG. At Talent Level 10, the initial hit deals 467.7%, the middle phase deals 29.2% Lunar-Charged DMG, and the final phase deals 210.5%. It costs 80 Energy and has a 20-second cooldown. Under Moonsign: Ascendant Gleam, nearby thunderclouds allow the attack to deal two additional middle-phase Lunar-Charged hits.

How does Thunderous Symphony work?

After Northland Spearstorm, the normal Burst temporarily becomes Thunderous Symphony. This shorter version costs only 30 Energy and deals 128.6% Lunar-Charged DMG. Under Ascendant Gleam with thunderclouds nearby, it gains another hit dealing 187.1%. The lower Energy cost and short replacement window are why this special Burst sits at the center of the normal on-field rotation.

What talent should you level first?

Elemental Burst > Elemental Skill >>> Normal Attack. Most of the important Lunar-Charged damage comes from the Burst system. Skill comes second because it controls Manifest Flame and Northland Spearstorm, while the standard Normal Attack talent contributes much less to the main damage loop.

Best Flins rotation

The cleanest rotation is to set up Hydro, Electro, and support effects before the main carry takes the field. Once those effects are active, move quickly through the Manifest Flame chain and make sure the six-second Thunderous Symphony window is not wasted.

1. Set up Hydro, Electro, and support effects.
2. Use Ancient Rite: Arcane Light to enter Manifest Flame.
3. Cast Northland Spearstorm.
4. Use Thunderous Symphony while its six-second replacement window is active.
5. Fill remaining field time with Manifest Flame Normal or Charged Attacks, then use Northland Spearstorm again if the window allows it.
6. Restart the team setup when Manifest Flame and support effects expire.

The main mistake is holding Thunderous Symphony for too long. Once Northland Spearstorm has been used, you only have six seconds to access the 30-Energy special Burst.

What is the Best Weapon for Flins?

Best-in-Slot: Bloodsoaked Ruins

Bloodsoaked Ruins is the clear Best-in-Slot weapon. At Level 90, it provides 674 Base ATK and 22.1% CRIT Rate. Its R1 passive, Mournful Tribute, increases Lunar-Charged DMG dealt to opponents by 36% for 3.5 seconds after using an Elemental Burst.

After triggering Lunar-Charged, the wielder also gains 28% CRIT DMG for six seconds and restores 12 Energy, with Energy recovery available once every 14 seconds. The synergy is direct: this carry already wants to Burst frequently, so the signature weapon rewards the normal rotation with Lunar-Charged damage, CRIT DMG, and Energy recovery.

Best 5-Star alternative: Staff of the Scarlet Sands

Staff of the Scarlet Sands provides 542 Base ATK and 44.1% CRIT Rate at Level 90. At R1, the wielder gains bonus ATK equal to 52% of Elemental Mastery. When an Elemental Skill hits an enemy, Dream of the Scarlet Sands grants another bonus equal to 28% of EM as ATK for 10 seconds, stacking up to three times.

This works well because Flins naturally gains EM from ATK through Whispering Flame. The main build concern is CRIT Rate: Staff of the Scarlet Sands gives a large amount on its own, while Night of the Sky's Unveiling can add another 30%. Artifact rolls should therefore avoid unnecessary CRIT Rate overcap and lean more toward CRIT DMG, ATK, useful EM, and enough ER to keep the rotation smooth.

Best 4-Star option: Deathmatch

Deathmatch provides 454 Base ATK and 36.8% CRIT Rate. At R1, it grants 16% ATK and 16% DEF when at least two enemies are nearby. Against fewer than two targets, the ATK bonus increases to 24%. It is a straightforward stat weapon rather than a Lunar-Charged-specific option, but the CRIT Rate and ATK still match the build well.

Is there a true F2P weapon?

Deathmatch is a strong 4-Star alternative, but it should not be treated as a true F2P weapon. For a no-premium fallback, Prospector's Shovel can serve as a more accessible option aimed at Electro-Charged and Lunar-Charged gameplay.

Which Gear and Stats Maximize Flins's Damage?

Best Artifact Set: Night of the Sky's Unveiling

4-Piece Night of the Sky's Unveiling is the best artifact set for the standard Lunar-Charged build. The 2-piece effect gives 80 Elemental Mastery. When nearby party members trigger Lunar Reactions, an on-field wearer gains Gleaming Moon: Intent for four seconds.

The 4-piece grants 15% CRIT Rate at Moonsign: Nascent Gleam or 30% CRIT Rate at Moonsign: Ascendant Gleam. All party members' Lunar Reaction DMG is also increased by 10% for each different Gleaming Moon effect held by party members. Because Flins raises the party's Moonsign by one level, the set connects directly with mechanics already built into his kit.

What main stats should Flins use?

An ATK Goblet may look unusual on an Electro DPS, but this build is centered on Lunar-Charged rather than only standard Electro DMG Bonus scaling. ATK also feeds Whispering Flame and the passive that raises Lunar-Charged Base DMG, so it contributes to several parts of the build at once.

Best substats

A practical priority is Energy Recharge to requirement > CRIT Rate / CRIT DMG > ATK% ≈ Elemental Mastery. The exact ER requirement changes with weapon and teammates. Supported setups can work around roughly 110–140% ER, with Double Electro teams often sitting around 130–140%; if he is the only Electro character, the requirement can become much higher.

Because Night of the Sky's Unveiling can provide 30% CRIT Rate, do not chase CRIT Rate on every artifact without checking the final total. This becomes especially important with Staff of the Scarlet Sands or Deathmatch, both of which already carry large CRIT Rate substats.

What Are the Best Team Comps for Flins?

His teams need reliable Hydro and Electro interaction because Electro-Charged is converted into Lunar-Charged while he is in the party. That makes Lunar-Charged the main team archetype rather than an optional side reaction.

Team 1: Flins + Ineffa + Sucrose + Xingqiu

This is the most complete all-around lineup among the supplied teams. Flins takes the main on-field window and converts the team's Electro-Charged reactions into Lunar-Charged. Ineffa functions as an off-field Lunar-Charged sub-DPS and adds defensive value, while Xingqiu supplies Hydro application to keep the reaction engine active. Sucrose fills the support slot with Elemental Mastery-oriented utility and resistance support.

The basic flow is to set up Ineffa and Xingqiu first, use Sucrose before the main damage window, then bring the carry on field for Ancient Rite: Arcane Light → Northland Spearstorm → Thunderous Symphony.

Team 2: Flins + Aino + Fischl + Xilonen

This lineup uses a different mix of Hydro application, off-field Electro, and resistance support. Aino supplies the Hydro side of Lunar-Charged and contributes to the Moonsign structure. Fischl adds off-field Electro damage and helps maintain Electro presence while the main DPS stays active. Xilonen fills the resistance-support position, helping the team push more damage during the burst window.

What about Flins + Aino + Sucrose + Iansan?

The third supplied team is also usable. Aino provides Hydro, Sucrose supports reaction-focused damage, and Iansan fills an ATK-oriented support slot. However, the exact optimized rotation for this specific four-character lineup was not included in the supplied data, so the final sequence is To be updated.

What Materials Are Needed to Upgrade Flins?

Character Ascension materials

To raise him from Level 1 to Level 90, you need the following materials. While farming, you can also check the latest Genshin Impact codes for currently available free Primogems and other account resources.

Talent materials

Because the recommended talent priority is Burst > Skill >>> Normal Attack, players who do not plan to triple-crown him can save resources by investing in Ancient Ritual: Cometh the Night first.

Which Constellations (Awakenings) Are Worth Getting?

What is the best stopping point?

C1 is the first strong stopping point. Reducing Northland Spearstorm from six seconds to four improves how often he can move through the special Skill loop, while the extra Energy directly addresses one of the build's main pressure points. For players willing to invest further, C2 is the stronger damage stopping point. The additional Lunar-Charged hit helps, but the larger prize is the 25% Electro RES reduction under Ascendant Gleam. C6 is much stronger, but it is clearly a high-investment endpoint rather than the efficient target for most accounts.

Is Flins Worth Pulling?

Yes, if you specifically want to build around Lunar-Charged. His biggest advantage is that the entire kit has a clear identity. He converts Electro-Charged into Lunar-Charged, improves that reaction through ATK and Moonsign, enters a dedicated Electro stance, and gains access to a cheap 30-Energy special Burst. His signature artifact set and weapon reinforce the same playstyle instead of pulling the build in different directions.

The main downside is team flexibility. He performs best inside a dedicated Lunar-Charged core and has fewer unrelated team options than a general-purpose Electro carry. If you are deciding whether to save for a future Flins rerun or spend on the currently listed characters, the Genshin Impact 7.0 banner schedule provides the current pull context, while the Genshin Impact 7.1 banner schedule is more useful for longer-term Primogem planning.

At C0, the full core system is already playable. C1 and C2 are the best early constellation targets, while Bloodsoaked Ruins is the premium weapon upgrade for players who want maximum Lunar-Charged performance. If you decide to spend for constellations or the signature weapon, you can review the available Genshin Impact top-up options before purchasing Genesis Crystals.

Frequently Asked Questions (FAQ)

Q: How much Energy Recharge does Flins need for a Lunar-Charged build?
A: A practical target depends heavily on weapon and teammates. Supported builds can generally work around 110–140% ER, with 130–140% being a common range in Double Electro setups. If he is the only Electro character, the requirement can rise much higher. Bloodsoaked Ruins helps because its passive restores 12 Energy after triggering Lunar-Charged. Do not chase one exact ER number at the cost of every offensive stat; the real goal is to prevent the special Burst cycle from stalling.

Q: Should Flins use an ATK Goblet or Electro DMG Goblet?
A: For the standard Lunar-Charged build, ATK% Goblet is the safer recommendation. His most important reaction damage does not behave like a standard Electro-only build, while ATK also feeds Whispering Flame and the passive that raises Lunar-Charged Base DMG. An Electro DMG Goblet is therefore not the default recommendation for this setup.

Q: Should Flins use Thunderous Symphony or his full 80-Energy Burst?
A: The special Thunderous Symphony is central to the normal on-field loop because Northland Spearstorm unlocks it for six seconds and lowers the Energy cost to only 30. The full Ancient Ritual: Cometh the Night costs 80 Energy and has its own multi-phase Lunar-Charged damage. During the standard Skill chain, the important rule is simple: once Northland Spearstorm is used, do not waste the six-second Thunderous Symphony window.
