COMPLETE FLINS GUIDE! Best Flins Build - Artifacts, Weapons & Teams | Genshin Impact 6.0

Flins is a five‑star Electro Polearm user introduced in Genshin Impact's Nod‑Krai region. At Lv.90 he has respectable base stats for an Electro DPS: 12 491 HP, 352 ATK and 809 DEF with a default CRIT DMG of 38.4%. He wields the polearm weapon type and his ascension stat increases his CRIT DMG, allowing him to scale well with CRIT‑oriented builds. Flins’s kit revolves around Electro damage, a unique Lunar‑Charged reaction and the Moonsign mechanic that enhances these reactions. His passive talents also reward building high ATK and Elemental Mastery, so his build should balance offensive stats and EM.

Normal Attack – Pocztowy Demonspear Flins performs up to five spear strikes with his normal attack. Charged attacks throw his spear forward at range, while plunging attacks strike the ground and deal AoE damage. The normal and charged attacks are largely physical at base, but they convert to Electro while his Elemental Skill is active.

Elemental Skill – Ancient Rite: Arcane Light → Northland Spearstorm Casting Ancient Rite: Arcane Light switches Flins into Manifest Flame form. During this state his normal and charged attacks deal Electro DMG that cannot be overridden by other infusions, his interruption resistance is increased and his plunging attack is disabled. The skill is replaced by Northland Spearstorm, which summons a flurry of spears in front of Flins, dealing AoE Electro damage and replaces his Elemental Burst with Thunderous Symphony for 6s. This skill has a fixed 6 s cooldown, encouraging short rotations.

Elemental Burst – Ancient Ritual: Cometh the Night → Thunderous Symphony Ancient Ritual: Cometh the Night unleashes Flins’s lamp, dealing AoE Electro damage followed by three additional instances of AoE Electro damage that are considered Lunar‑Charged DMG. When cast after Northland Spearstorm, the burst becomes Thunderous Symphony. This special burst consumes less energy to unleash a single powerful instance of AoE Electro damage considered Lunar‑Charged DMG, and if Moonsign: Ascendant Gleam stacks are present, he deals an extra instance. These Lunar‑Charged hits can trigger his passives.

Flins’s passives play a huge role in his build:

1. Symphony of Winter – grants Flins a buff based on the party’s Moonsign. When he has the Moonsign: Ascendant Gleam status, Lunar‑Charged reactions triggered by Flins deal 20 % additional damage.
2. Moonsign Benediction: Old World Secrets – converts any party member’s Electro‑Charged reaction into a Lunar‑Charged reaction, and for every 100 ATK that Flins has, the base damage of Lunar‑Charged increases by 0.7 % (up to 14 %). This passive also increases the party’s Moonsign level while Flins is in the party.
3. Whispering Flame – increases Flins’s Elemental Mastery by 8 % of his ATK up to 160 EM. Because Lunar‑Charged scales with EM, this passive rewards stacking ATK on Flins.
4. A Light in the Dark – reveals resources unique to Nod‑Krai on the mini‑map and hints at Flins’s ability to “decipher the whispers of the Wild Hunt”.

Together, these passives encourage players to build Flins with high ATK to boost EM (via Whispering Flame) and to empower Lunar‑Charged damage through Moonsign Benediction. The kit also requires a Hydro source to convert Electro‑Charged reactions into Lunar‑Charged, so team composition is crucial.

Prioritise CRIT Rate/CRIT DMG, ATK %, Elemental Mastery and Energy Recharge. Flins gains additional EM from ATK via Whispering Flame, so ATK % remains his best sub‑stat. Elemental Mastery boosts Lunar‑Charged reactions, while Energy Recharge helps maintain burst uptime, particularly when Northland Spearstorm reduces his burst’s energy cost. HP/DEF sub‑stats have little value because his kit does not scale on survivability.

Although Flins is a new character, existing artifact sets synergise well with his kit. The following recommendations are based on how his skills and passives function:

1. Night of the Sky's Unveiling 2-Pc: Increases Elemental Mastery by 80. 4-Pc: When party members trigger Moonglare reactions, if the equipping character is on the field, gain the Gleaming Moon: Intent effect for 4s: Increases CRIT Rate by 15%/30% when the party's Moonsign is Nascent Gleam/Ascendant Gleam. All party members' Moonglare reaction DMG is increased by 10% for each different Gleaming Moon effect that party members have. The equipping character can trigger this effect while off-field.
2. 4‑pc Thundering Fury – Increases Electro DMG Bonus and reduces the cooldown of Elemental Skill after Electro‑charged/Lunar‑Charged reactions. This set rewards spamming Ancient Rite: Arcane Light/Northland Spearstorm, which has a flat 6 s cooldown, and increases reaction damage.
3. 4‑pc Gilded Dreams – Provides Elemental Mastery and ATK buffs based on the team’s elemental composition. Because Whispering Flame converts Flins’s ATK into EM, this set further boosts his reaction damage.
4. 4‑pc Emblem of Severed Fate – Provides Energy Recharge and increases burst damage proportionally to Energy Recharge. This set works well if Flins’s burst forms (Cometh the Night/Thunderous Symphony) make up most of his damage.
5. 2‑pc combinations – For players lacking good four‑piece sets, a combination of two‑piece ATK % (e.g., Gladiator’s Finale/Shimenawa’s Reminiscence), Electro DMG Bonus (Thundering Fury) and Elemental Mastery (Gilded Dreams/Wanderer’s Troupe) can be used. These combos maintain decent offensive stats while waiting for an ideal four‑piece set.

Flins’s Moonsign Benediction converts Electro‑Charged reactions into Lunar‑Charged reactions. Therefore, teams must include at least one Hydro unit to apply Hydro to enemies consistently. The core idea is to cycle between Flins’s Electro attacks and a Hydro applicator to continuously trigger Lunar‑Charged reactions. Sample teams include:

1. Bloodsoaked Ruins (5★) – This is Flins’s signature weapon. It provides CRIT Rate as its secondary stat and increases Lunar‑Charged damage. Its ability Mournful Tribute states that after using an Elemental Burst, Flins’s Lunar‑Charged DMG is increased by 36 % for 3.5 s, and after triggering a Lunar‑Charged reaction he gains Requiem of Ruin, which increases CRIT DMG by 28 % for 6 s and restores 12 energy. The weapon directly complements his kit and ensures frequent bursts.
2. Staff of Homa / Primordial Jade Winged‑Spear (5★) – High‑CRIT weapons that provide strong ATK/CRIT boosts. They are good generalists if Bloodsoaked Ruins is unavailable.
3. Vortex Vanquisher / Engulfing Lightning (5★) – Provide ATK and Energy Recharge respectively. The Energy Recharge from Engulfing Lightning synergises with teams that rely heavily on Flins’s burst.
4. The Catch (4★ free) – Offers Energy Recharge and increases burst DMG and CRIT Rate. Since Flins’s burst deals significant damage, The Catch is a strong budget option.
5. Deathmatch / Blackcliff Pole (4★) – Provide CRIT Rate/CRIT DMG and ATK bonuses. These weapons are viable if your artifact sub‑stats lack CRIT.

Flins is a dynamic Electro polearm DPS who introduces the Lunar‑Charged reaction. His kit scales on ATK and Elemental Mastery – ATK increases his EM and the base damage of Lunar‑Charged reactions via his passives. Building Flins involves stacking ATK and CRIT stats while maintaining sufficient EM and Energy Recharge. The Bloodsoaked Ruins polearm is his best weapon since it boosts Lunar‑Charged damage, CRIT and energy recovery. Pair him with Hydro supports to trigger Lunar‑Charged reactions and consider Anemo support and a defensive unit to round out the team. With the right artifacts, weapons and teammates, Flins can become a powerful Electro damage dealer in Genshin Impact.
