Secrets to Mastering Fire Genasi: The Most Powerful Multiclass in Genshin Impact

In the dynamic world of Genshin Impact, Windows Genre Basics (Genasi) are legendary for their versatile and explosive power. Among all the Brasier builds, the Fire Genasi stands out as one of the most versatile and highly sought-after multiclass characters thanks to its potent fire-based combos and scaling benefits. Whether you’re a seasoned player or new to the game, mastering the Fire Genasi unlocks tremendous potential in both solo play and team compositions. In this guide, we dive into the secrets of harnessing the Fire Genasi’s full power, focusing on optimal character builds, skill synergies, and strategic play to dominate every battlefield.


Understanding the Context

Why Fire Genasi Reigns Supreme Among Multiclass Builds

Fire Genasi offers a unique blend of burst damage, strong survivability through elemental resistance, and exceptional scaling with level and Elemental Burst usage. Unlike Indexed or Elemental Dev + Ranked builds, Fire Genasi combines high damage output with sustained survivability, making it ideal for both aggressive playstyles and tanky, prolonged engagements. When multiclassed properly—typically Fire + Lightning or Fire + Cryo—the Genasi becomes a versatile powerhouse capable of adapting to any situation.

The secret to mastering Fire Genasi lies not only in choosing the right main character and rank but also in optimizing your weapon choice, skill allocation, and Elemental Burst usage.


Key Insights

Choosing the Right Main Character & Rank

Fire Genasi’s strength heavily depends on your base character. While any Genasi archetype can work, top tier picks often feature:

  • Mulan (Fire) – Exceptional fire damage amplification with state-of-the-art attack speed and reliable bonus stats that boost Fire damage significantly.
  • Fischl (Fire) – Strong ranged burst with weather support (though not pure Fire, strong synergy with Lightning or Cryo mansions for hybrid builds).
  • Zeal/Pseudo Fire Weapongrades (Fire) – Fire-tendrilled weapons offer high primary damage and great elemental burst synergy.

Top recommendations for Fire Genasi include Mulan (Fire) and Reyland (Fire) at desync/5 for maximum burst and sustained activity. Rank 3–Definitive is standard, but pushing higher with Link Points enhances your elemental scaling and damage multipliers.


Final Thoughts

Skill Synergy & State Optimization

The core of Fire Genasi power lies in continuous state deployment and damage compounding. Key skills include:

  • Fire Arrows – For ranged AoE and state (paint burn). Maximize with Electro element to trigger Radiant Exception, stacking burn and freezing enemies, boosting overall AoE and risk.
  • Fire Strike – A high-DPS melee skill that scales well with Elemental Burst. When charging, especially with Cinder Burst, damage amplifies dramatically.
  • Blazing Chainsaw (Zeal Reborn) or Flame Surge (Fischl hybrid) – For sustained burn and pressure.
  • Flare System (via Elemental Burst activation) is essential; build Low Causality + Flares per Link Point to amplify energy regulation and multi-stack burns.

Pro Tip: Link Counterflame (if available through gear or passive) or Status Burst sources to extend burn duration and risk tolerance.


Elemental Burst: The Power Catalyst

Elemental Burst transforms the Fire Genasi from strong to dominant. The optimal choice depends on build type:

  • Fire Fire Burst – Standard high-damage AoE with burn; pairs perfectly with someone carrying flag or shield state.
  • Fire Lightning Burst – Ideal for multi-target DPS and fast stacks. Great against groups; synergizes with lightning-electro combos.
  • Fire Cryo Burst (if hybrid builds): Double element burns enemies if supported, but rare for pure Fire–stick to Fire–Lantern mains.

Optimization note: Allocate Link Points to FE Burst gain, energy capacity, and damage multipliers, especially Flares and Magic Warning, to maximize burn spread and threat.
