Furina, a 5★ Hydro Sword character in Genshin Impact, excels in providing off-field damage, beneficial effects for the whole team, and has unique ways to manage team HP. As the Hydro Archon, she shines even in a support role, and her abilities dictate how her team is formed. This guide will cover Furina’s optimal builds, weapons, artifacts, and team compositions.

 FURINA PLAYSTYLE

Role: Off-field Support / Sub-DPS (On-field DPS at C6)

Elemental SKILL [E] :

Fontaine’s lore introduces two arkhe alignments: Ousia and Pneuma. Most Fontaine characters have one of these. However, our Archon Furina can switch between both with her Charged Attack.

1. Ousia-Aligned Skill

• Summons Salon Members (Octopus, Seahorse, Crab) to deal off-field Hydro DMG.

• Consumes teammates’ HP while each summon applies Hydro and damages enemies, more damage when party members have more than 50% HP.

• Hydro Particle generation on hit (2.5s cooldown)

• Summons  target the same enemy as the active character and follows around the character.

• Attack frequency varies among summons (Seahorse > Octopus > Crab), while Crab has the highest damage and HP drain.

2. Pneuma-Aligned Skill

• Summons the Singer of Many Waters, a stationary healing aura that restores HP based on Furina’s Max HP.

• Does not deal damage or apply Hydro.

• Can be re-positioned with Furina’s Charged Attack.

• Heals the on-field character every 2s within a large range, indicated by a water ring.

Tip: Casting either Skill lets Furina walk on water—handy for exploring Fontaine’s areas!

Elemental Burst [Q] :

Deals AoE Hydro DMG and grants Universal Revelry:

• Deals a burst of Hydro DMG to nearby enemies (weak Hydro application).

• Activates Fanfare, which accumulates points whenever party members lose or gain HP.

• As Fanfare points go up, your team’s DMG Bonus and Incoming Healing Bonus rise.

• At C0, can stack up to 300 points → up to +75% DMG and +75% Healing.

• No snapshotting means your DPS continuously benefits the moment you gain more Fanfare points.

 Talent Level Priorities

Recommendation: Skill (E) ≥ Burst (Q) >>> Normal Attack (NA)

Passive Talents

A1 Passive (“Endless Waltz”) :

Furina will heal a nearby party member for 2% of their Max HP once every 2s within the next 4s, if “overflowing” heals occur. Typically requires another big healer so you can exceed a character’s max HP threshold to trigger it.

A4 Passive (“Unheard Confession”) :

Boosts DMG and Healing of Furina’s Skill based on her Max HP (up to 40k HP).

Utility Passive :

Reduces underwater ability cooldown in Fontaine, making exploration easier.

 Constellation Overview

Furina is fully functional at C0, but each constellation adds noticeable perks.

C1 & C2 for off-field synergy; C6 for unlocking on-field DPS.

 Artifact Setup

Core Stats: HP%, Crit Rate/DMG, ER%. Aim for enough ER to keep her Burst on cooldown (~160% at C0).

Substats Priority: Crit DMG ≥ Crit Rate > HP% > Energy Recharge

Artifact Set Choices

4pc Golden Troupe

Best for off-field DPS via Salon Members. Furina’s Summons do the bulk of her damage, and Golden Troupe significantly boosts Elemental Skill DMG.

4pc Tenacity of the Millelith

More of a support-oriented set that gives ATK buff to the team. Salon Members can keep triggering its effect.

 Weapon Choices

 Team Synergy

Furina can function in various team comps, but a dedicated healer is strongly advised at C0 to offset her HP drain and stack Fanfare faster. Her DMG buff from Burst applies to all Elements, so she’s flexible across reaction teams or mono-element lineups.

Hydro-Heavy Teams (Double/Triple Hydro)

• Examples: Furina + Kokomi/Yelan/Xingqiu + Anemo

• Gains Hydro Resonance (+25% HP), lowers ER needs, and frees artifact slots for HP% or Crit. Perfect synergy to amplify Furina’s off-field damage.

Reverse Vaporize (Pyro DPS)

• Examples: Furina + Hu Tao/Arle + Xingqiu/Yelan + Bennett

• Pyro DPS drain (Hu Tao’s HP burn, for instance) + Bennett’s big heals = easy Fanfare stacks. Furina’s Summons can also Vaporize for extra damage.

Forward Vaporize

• Examples: Furina + Xiangling/Klee + Bennett + (Anemo buffer)

• Furina’s off-field hits get Vaporized by your Pyro unit’s aura—massive boost to Furina’s personal DPS.

Quickbloom / Dendro-Electro Cores

• Examples: Furina + Nahida/Baizhu + Cyno/Kuki + Flex

• Slower Hydro app helps maintain Quicken aura. Meanwhile, HP drain from Kuki/Cyno fueling Fanfare is a perfect synergy.

Geo/Anemo “Hypercarry”

• Examples: Furina + Navia+  Benette + Xianyun

• Example: Furina + Benette + Wanderer/Xiao + Faruzan (Anemo)

• Furina’s universal DMG buff benefits raw damage dealers who don’t rely on reactions. They appreciate the extra party healing for survival while she’s off-field.

Freeze Teams

• Examples: Furina + Ayaka/Ganyu/Wriothesley + Cryo Healer/Buffer

• Consistent, albeit slower, Hydro application to keep enemies frozen. Pair with Charlotte/Jean for big group healing to support Fanfare.

 TL;DR

• Furina’s Distinctive Mechanic: Balancing HP drain and healing is central to her kit. She’s incredible at pumping out off-field damage while juicing your team’s DPS with Fanfare-based buffs.

• Healer Necessity: Unless you have C1 or a robust healing investment on Furina, do bring a solid group healer to keep everyone above 50% HP and to maximize the Summons’ damage.

• Flexibility: She’s not element-locked for buffs, so any high-DPS carry—be it Pyro, Hydro, Electro, Anemo, or Geo—can make good use of her universal DMG boost.

• Constellations: While fully functional at C0, going for C1/C2 significantly smooths out her ramp-up time and overall comfort. C6 transforms her entire playstyle into a potent on-field Hydro DPS.

In short, Furina is a powerful Hydro Sub-DPS and party buffer. She excels in many team setups thanks to her game-changing Fanfare buffs and dual Arkhe flexibility—plus, she literally walks on water, leaving Teyvat’s bridge builders out of business. Build her well, pair her with a capable healer, and watch your whole team’s damage flow in style!
