Iansan

Iansan is a 4-star Electro polearm support. She provides Electro application and team buffs that help Electro reaction carries, slotting into aggravate and Electro-Charged compositions.

How to Play

Slot her behind an Electro or reaction carry to add Electro and a buff. See her placement on the Genshin tier list.

Best Build

Top Weapons: Calamity Queller (best-in-slot, caps her ATK buff), Engulfing Lightning for higher ER needs, or 4-star Favonius Lance / Tamayuratei no Ohanashi. Artifact Set: 4pc Scroll of the Hero of Cinder City (energy + DMG buff to allies), or Noblesse Oblige as a generalist. Main Stats: Sands ATK% or ER, Goblet ATK%, Circlet ATK%. Substats: ATK% > Energy Recharge.

Best Teams

ATK-buff support in nearly any hypercarry team. She buffs team ATK via her Burst, pairing with a strong main DPS plus an Electro teammate to cut her ER needs (down to ~160%).

Kit Overview

• Skill: Quick Electro damage and energy support.
• Burst: Grants a large flat ATK buff to the active character, scaling off her own ATK.
• Core loop: Stack ATK, fire Burst off-cooldown; flexible universal buffer.

Pros and Cons

Pros: Universal team-wide ATK buffer, low field time, fits many comps. Cons: ER-hungry without an Electro partner, buff value depends on her own ATK investment.
