Best Iansan Build for 2026

Iansan is the closest thing to a second Bennett, and the comparison is misleading in one important way: Bennett's buff is a circle you stand in, while Iansan's is a moving buff that decays unless your on-field carry keeps covering ground. Understanding that single condition is the difference between a top-tier buffer and a mediocre one. Her burst (The Three Principles of Power, 70 energy, 12s duration) summons the Kinetic Energy Scale, which follows the active character and converts a share of Iansan's own ATK into an ATK bonus for them. Below 42 Nightsoul points the bonus scales with how many points she has left; at 42 or more the Scale switches to its stronger state, where the conversion is a much larger flat percentage of her ATK. The Scale then does something no other buffer does: it logs how far the active character moves and refunds Nightsoul points every second based on that distance. Movement is her fuel. In practice her loop is skill (Thunderbolt Rush, which restores 54 Nightsoul points and gives a free Swift Stormflight stomp off a normal attack) into burst, then swap. Her first ascension passive grants Precise Movement after that stomp lands, adding 20% ATK and extra Nightsoul restoration, so never skip the stomp. Her fourth ascension passive also heals the active character whenever Nightsoul Bursts occur nearby, which is small but real sustain. Build her for ATK above everything else, because both tiers of her buff scale off her ATK stat. Energy Recharge comes next - a 70-cost burst with no particle generation during its uptime usually lands somewhere in the 160-180% range, less with a Favonius Lance in the party. Staff of Homa is the premium pick purely for the ATK it produces; Favonius Lance is the team-friendly one. For artifacts, Scroll of the Hero of Cinder City is excellent when the team's reactions line up with her Electro, and Noblesse Oblige is the safe fallback. Her best partners are carries that constantly reposition: Varesa, Mavuika, Kinich, Clorinde, Gaming, Xiao. Each of them generates distance as a side effect of their normal rotation, which keeps her Nightsoul gauge topped up and her buff in the strong state. Where she struggles: carries that stand still or attack in place - Neuvillette channelling his beam, Yoimiya parked in her normal attack string, any turret-style gameplay - starve her Nightsoul gauge, drop her to the weaker conversion tier, and can end the Scale early. She also contributes almost no damage and only incidental healing, so in teams that cannot use an ATK buff she is a wasted slot.
