Furina Genshin Impact Guide: Complete Build, Teams & Optimization Tips

Introduction

Furina, the Hydro Archon of Fontaine, continues to command attention in Genshin Impact with her remarkable versatility and team synergy. Now entering her second rerun and third overall banner, Furina remains an essential support character across various team compositions. Even with the emergence of powerful alternatives like Xilonen and Citlali, her value in the current meta is far from diminished.

What sets Furina apart is her unique design: a dual-form kit that balances damage-dealing and healing through her Ousia and Pneuma alignments. This makes her exceptionally adaptable, capable of elevating a broad spectrum of characters—especially those who struggle to shine without the right support. As we dive into this 2025 guide, we’ll explore the best strategies to build Furina, how to optimize her artifact and weapon choices, and the most effective team compositions that maximize her impact.

Understanding Furina’s Kit and Role in 2025

Furina’s strength lies in her dual-alignment ability, toggling between Ousia and Pneuma modes. This mechanic, unique to her character, defines how she interacts with your team. In her default Ousia mode, Furina summons three distinct marine spirits that deal off-field Hydro damage, synchronizing their attacks with the active character's target. While effective, these companions siphon HP from your team when their health is above 50%, effectively trading survivability for amplified damage.

In contrast, switching to her Pneuma alignment transforms her skill into a single summon that heals the active character. While rarely utilized in high-end content due to limited healing output and team synergy, it remains situationally useful for exploration or niche compositions involving Constellation 6 setups.

Pros of Furina’s Kit:

• Strong off-field Hydro application in Ousia mode.

• Exceptional team-wide buffs from her Elemental Burst.

• Scales damage and healing output synergistically.

• Versatile enough for varied archetypes and roles.

Cons of Furina’s Kit:

• Ousia mode causes HP drain, requiring reliable healing.

• Hydro application may be inconsistent due to staggered companion attack timings.

• Suboptimal in teams relying on precise elemental timing like melt setups.

Elemental Skill: Salon Members

Her skill, Salon Solitaire, operates as the primary source of her off-field presence. When activated in Ousia mode, Furina calls upon three marine-themed companions that attack in rotation. These attacks scale with her max HP, and when team HP is above the 50% threshold, they initiate passive HP drain to increase damage output. This introduces both strategic benefits and resource management challenges.

Elemental Burst: Let the People Rejoice

Furina's burst is one of the strongest team support abilities currently available. It accumulates "Fanfare Stacks" whenever HP is gained or lost within the party. These stacks grant universal damage bonuses and healing boosts. At talent level 10 and zero constellations, she can provide up to 75% DMG Bonus when 300 stacks are achieved—making her a central buffing unit for virtually any team setup.

Artifact Selection and Stat Optimization

Choosing the right artifact set is crucial for unlocking Furina’s full potential. Despite lacking a set tailored specifically for her hybrid support-playstyle, Furina benefits immensely from sets that enhance her Elemental Skill damage and overall off-field presence.

Best Artifact Sets for Furina in 2025:

• Golden Troupe (4-piece)

  • Bonus: Grants up to 70% Elemental Skill DMG for off-field characters.

  • Why it works: Maximizes the damage output from her summoned companions while off-field. Ideal for her default Ousia mode.

• Tenacity of the Millelith (4-piece) (Situational)

  • Bonus: Boosts team ATK and provides bonus shield strength when the skill triggers on-field.

  • Best for: Support setups where Furina doesn’t deal damage directly, such as mono-pyro or Lyney teams.

• Hybrid Mix (2-piece HP% + 2-piece Hydro DMG or Energy Recharge)

  • Best used for: Players with incomplete sets or seeking to balance her skill output with her burst utility.

Main Stats Priority:

• Sands: HP% or Energy Recharge (based on weapon and team needs)

• Goblet: HP% (Hydro DMG only recommended if she has C2)

• Circlet: Crit Rate or Crit Damage (based on ratio)

Substats Priority:

1. Crit Rate / Crit Damage

2. Energy Recharge

3. HP%

4. Flat HP

Energy Recharge Threshold:

• Solo Hydro Role: Aim for ~200% ER

• With Another Hydro Unit: 150%–180% ER typically suffices

• With Favonius User: 160%–180% is optimal

Best Weapons for Furina: Ranking & Usage Context

• Team: Neuvillette, Furina, Kazuha/Xilonen, Baizhu/Zhongli/Charlotte

4. Clorinde Quickbloom Variant

• Team: Clorinde, Furina, Fischl, Nahida

• What to know: Clorinde’s Bond of Life mechanic feeds into Furina’s Fanfare buffing. This healerless comp relies on self-sustain and high burst output.
