Iansan made her long-awaited debut as a 4-star Electro Polearm character hailing from Natlan, specifically serving as the head coach of the fitness club at the Collective of Plenty. First teased years prior in the official Teyvat Chapter Storyline Preview, her kit centers on Nightsoul mechanics, mobility-scaling flat attack buffs, and swift support utility that pairs exceptionally well with active, high-movement characters. Unlike traditional off-field supports who drop a turret and leave, Iansan rewards dynamic positioning and active rotation management.
Building Iansan effectively requires understanding her unique role as a support who bridges Natlan's regional mechanics with team-wide utility. Whether you pulled her during her version 5.5 release or are slotting her into modern team compositions, maximizing her potential depends on proper artifact allocation, talent priority, and weapon selection without wasting resources on unnecessary stats.
Iansan Combat Kit and Mechanics
Iansan's core gameplay revolves around her Nightsoul's Blessing state and the Limited-Edition Kinetic Energy Scale deployed via her elemental burst. Her kit is built to keep the active character moving while stacking helpful combat bonuses.
Elemental Skill and Movement
Her elemental skill, Thunderbolt Rush, propels her forward while dealing Nightsoul-aligned Electro damage. Holding the sprint button shifts her into Rushing Thunderbolt mode, drastically boosting movement speed and letting her scale terrain or glide across liquid Phlogiston with damage immunity. This mobility isn't just for exploration; it feeds directly into her combat rhythm and keeps her agile during chaotic spiral abyss floors.
Elemental Burst and Buffing
Her burst, The Three Principles of Power, summons the Kinetic Energy Scale and grants initial Nightsoul points. When nearby party members trigger a Nightsoul Burst, Iansan gains the Warming Up effect, healing the active character based on her attack. Crucially, her buffs scale with movement and active positioning, making her an ideal partner for hyper-mobile damage dealers.
- Normal Attack (Weighted Spike): Primarily used for transitional strikes, though personal damage scaling is low.
- Enhanced Resistance Training: A1 passive that grants precision movement effects after successful Swift Stormflight strikes.
- Kinetic Energy Gradient Test: A4 passive that converts energy consumption into smooth rotation loops.
Best Artifacts and Weapons
Because Iansan functions primarily as a support and buffer rather than a primary damage dealer, your stat priorities should lean heavily into energy recharge and attack scaling.
Artifact Recommendations
The undisputed best-in-slot artifact set for her is the 4-piece Scroll of the Hero of Cinder City. Because she is a Natlan character capable of triggering Nightsoul interactions easily, she maximizes the full set bonus, granting a massive elemental damage bonus to her teammates whenever she triggers a reaction. Look for Energy Recharge on your sands, Attack percentage or HP on your goblet depending on healing needs, and a Crit Rate circlet if you run utility weapons.
Weapon Choices
- Favonius Lance: A stellar 4-star option that solves energy issues for both Iansan and her team through crisp particle generation on critical hits.
- Natlan Craftable Polearms: Viable budget alternatives that fit regional aesthetic and stat requirements.
- Vortex Vanquisher: A 5-star stat stick option if you need raw attack scaling.
Optimal Team Compositions
Iansan shines brightest in teams where the main damage dealer moves frequently and scales with attack. Her flat attack buffs and elemental application allow her to slip into several diverse archetypes.
- Chasca Hypercarry: Pairing Iansan with Chasca, Bennett, and Furina lets Chasca capitalize on floating combat styles while receiving huge elemental damage boosts from Iansan's scroll set and electro bullet conversions.
- Electro-Charged Flex Teams: She slots smoothly into fast-paced rotations alongside hydro enablers and anemo crowd controllers, keeping energy loops stable.

Frequently Asked Questions
Is Iansan a 4-star or 5-star character?
Iansan is a 4-star Electro polearm character who debuted during version 5.5. This makes her significantly easier to obtain and constellation-upgrade compared to limited 5-star units.
Do I need to level up Iansan's normal attacks?
No. Since her personal damage contribution is quite low and her value comes entirely from utility, healing, and buffs, you can safely leave her normal attacks at level 1 to save precious boss materials and mora.
How does the Kinetic Energy Scale work?
When you cast her elemental burst, she deploys the scale which interacts with party member Nightsoul bursts to grant healing, restore energy, and trigger passive buff conditions that amplify active character output.
What are her best constellation milestones?
Her C2 is notable because it grants her passive movement buff automatically upon casting her burst and provides a direct attack percentage bonus to your active character. Her C6 further extends scale duration and injects team-wide damage boosts.
