Who is Iansan?

Iansan is a 4★ Electro Polearm Support from Natlan's Collective of Plenty tribe, rated SS-tier Support by Game8. She is a renowned fitness trainer who provides massive ATK buffs that scale with her own ATK and her Kinetic Energy Scale mechanic — buffs that rival Bennett for movement-intensive carries like Varesa, Xiao, and Mavuika. Her Nightsoul integration makes her a natural fit for Natlan teams. Source: https://game8.co/games/Genshin-Impact/archives/345881

Kit Summary

Normal Attack (Weighted Spike)

Three-hit polearm combo; used to build Nightsoul points in rotation.

Elemental Skill (Thunderbolt Rush)

Charges forward dealing Nightsoul-aligned Electro DMG; grants 54 Nightsoul points and enters Nightsoul's Blessing for 5s.

Elemental Burst (The Three Principles of Power)

AoE Electro DMG; summons Kinetic Energy Scale following the active character, providing an ATK bonus that scales with Iansan's ATK and active Nightsoul points. Scale enters "Ardent Support" (enhanced buff) at 42+ Nightsoul points. Scale restores Nightsoul points based on teammate movement distance.

F2P Verdict

✅ Worth ItPatch Luna VII

An SS-tier ATK buffer who rivals Bennett for movement-heavy carries. The bigger your carry moves around, the stronger her buff gets. Accessible as a 4★ and strong at C0 with further gains at C2 and C6.

Available as a 4★ — obtainable on featured/standard banners without heavy pulling.

Favonius Lance is the best free polearm: ER + CRIT-based particle generation reduces ER investment.

The Catch (Inazuma fishing reward) and Prototype Starglitter (craftable) are solid alternatives.

Pure ATK% build — no CRIT stats needed unless using Favonius Lance.

Pair with movement-intensive carries (Varesa, Xiao, Mavuika) to maximize her Kinetic Energy Scale buff. Source: https://game8.co/games/Genshin-Impact/archives/345881

Frequently Asked Questions

Is Iansan's buff affected by movement?

Yes — her Kinetic Energy Scale restores Nightsoul points based on teammate movement distance, boosting her buff into Ardent Support (enhanced) state. Mobile carries like Varesa and Xiao maximise this. Source: Game8.

What ATK should Iansan target?

2,500+ ATK — her buff scales directly with her ATK stat. Source: Game8.

What Energy Recharge does Iansan need?

180-200% without an Electro teammate, or 140-160% with one. C1 (Energy restore from Nightsoul consumption) reduces requirements. Source: Game8.

Is Iansan good for non-Natlan teams?

Yes — she works in Xiao Anemo teams and any team with movement-intensive carries, not just Natlan characters. Source: Game8.
