Who Is Iansan in Genshin Impact?
Iansan is a 4-star Electro Polearm character from the nation of Natlan. She was added to Genshin Impact in Version 5.5, released on March 26, 2025. Her title is “Tempered in Molten Stone” and her constellation is Carnotaurus. This guide has been updated to reflect the current Version 7.0 meta.
Lore-wise, Iansan is a fitness instructor and head coach from the Collective of Plenty tribe in Natlan. She is a champion mentor of the Pilgrimage of the Return of the Sacred Flame and a renowned nutritionist known for giving healthy smoothies and diet advice to the people around her. She holds the Ancient Name UWZ, meaning “Uwezo” — which translates to power. She is voiced by Katrina Salisbury in English.
In combat, Iansan is one of the strongest support characters in the game. Her kit revolves around buffing the active character’s ATK while using a movement-based Nightsoul Points system that rewards mobile DPS characters.

Iansan’s Talents and Skills Explained
Normal Attack
Iansan performs up to 3 consecutive spear strikes with her Polearm. Her Charged Attack consumes Stamina and makes her lunge forward, dealing damage along the path. Her Plunging Attack drops from mid-air, damaging enemies below and dealing AoE damage on impact.
While in her Nightsoul’s Blessing state, her Charged Attack transforms into Swift Stormflight, which deals Nightsoul-aligned AoE Electro DMG without consuming Stamina.
Elemental Skill – Thunderbolt Rush
Iansan charges forward, dealing Electro DMG to enemies in her path and generating 54 Nightsoul Points. She then enters the Nightsoul’s Blessing state. Using a Normal Attack within 5 seconds of this skill activates an enhanced Charged Attack at no Stamina cost.
While in Nightsoul’s Blessing, Iansan gets greatly increased movement speed and can enter a mode called Rushing Thunderbolt, which lets her cross water. She can also use this skill during exploration by holding it, letting her sprint, leap, and move swiftly across the map.
Elemental Burst – The Three Principles of Power
This is Iansan’s most important ability. When activated, she stomps the ground and deals Nightsoul-aligned AoE Electro DMG. She also summons the Kinetic Energy Scale, a special item that follows the active character around the field.
The Kinetic Energy Scale does two key things:
- ATK Buff: It increases the active character’s ATK based on Iansan’s own ATK stat and her current Nightsoul Points. The more points she has, the bigger the buff.
- Nightsoul Restoration: Every time the active character moves around the field, Iansan regains Nightsoul Points. This keeps the buff strong as long as your DPS keeps moving.
If Iansan’s Nightsoul Points overflow past the cap, she gains the Extreme Force effect, which increases the active character’s DMG by 25% for 3 seconds.
Passive Talents
1st Ascension Passive – Enhanced Resistance Training: After Swift Stormflight hits enemies, Iansan gains the Precise Movement effect for 15 seconds. During this time, her ATK increases by 20%, and she gains extra Nightsoul Points whenever the Kinetic Energy Scale restores them. If any party member consumes or restores Nightsoul Points, the next Scale restoration gives her 4 extra Nightsoul Points. This effect resets every 2.8 seconds.
4th Ascension Passive – Warm-Up Sequence: When a nearby party member triggers a Nightsoul Burst, Iansan gains the Warming Up effect for 10 seconds. During this time, whenever she restores at least 1 Nightsoul Point, she heals the active character for 60% of her own ATK. This gives Iansan minor but consistent healing without needing a dedicated healer slot.
Night Realm’s Gift Passive: While in the Nightsoul’s Blessing state in combat, Iansan restores 15 Elemental Energy for every 6 Nightsoul Points she consumes. This can trigger once every 18 seconds and helps her manage Energy efficiently.
Utility Passive: As a member of the Collective of Plenty, Iansan can sprint across terrain, break obstacles, and walk on water using Nightsoul Points and Phlogiston for exploration. For more on Natlan’s terrain and exploration, check out our guide on how to unlock the Golden Hall Teleport Waypoint.
Iansan Constellations Guide
Iansan is strong even at C0, but her constellations make her noticeably better. Here is a breakdown of each one:
C1 – Starting’s Never Easy
While in Nightsoul’s Blessing state during combat, Iansan restores 15 Elemental Energy for every 6 Nightsoul Points consumed. This can trigger once every 18 seconds. This helps her spam her Elemental Burst more frequently, especially if you have not built much Energy Recharge yet. Pull Value: Medium.
C2 – Laziness is the Enemy!
When Iansan uses her Elemental Burst, she also gains the Precise Movement effect from her Ascension Passive. If she is off-field while Precise Movement is active, the active character also gains a bonus 30% ATK increase on top of the Scale’s normal buff. This is a massive upgrade and considered the most important constellation to aim for. Pull Value: High.
C3 – Scientific Diet Planning
Increases the level of Thunderbolt Rush (Elemental Skill) by 3, up to a maximum of Level 15. Since Iansan’s Skill is not her primary source of value, this is a minor improvement. Pull Value: Low to Medium.
C4 – Stacking Up the Reps
While the Kinetic Energy Scale is present, Iansan gains 2 stacks of Surging Force whenever the active character uses their Elemental Burst. Each stack causes the Scale to restore 4 additional Nightsoul Points the next time it restores. This helps keep her Nightsoul Points topped off more consistently. Pull Value: Medium.
C5 – Keep Pushing Forward
Increases the level of The Three Principles of Power (Elemental Burst) by 3, up to a maximum of Level 15. Since her Burst is everything, this is a meaningful upgrade. Pull Value: Medium to High.
C6 – Teachings of the Collective of Plenty
Extends the Kinetic Energy Scale’s duration by 3 seconds and adds a direct 25% DMG increase to the active character. This pushes Iansan’s buffing ceiling significantly higher and makes her one of the best supports in the game at full constellations. Pull Value: High.
Overall constellation investment priority: C2 > C5 > C6.
Iansan Best Build
Best Weapons for Iansan
Iansan is a support character, so her weapon choice focuses on Energy Recharge and ATK. Here are the best options:
- Engulfing Lightning (5-star) – Best in Slot: This is Raiden Shogun’s signature weapon and Iansan’s top pick. It provides a massive Energy Recharge boost and converts ER into bonus ATK, which directly scales her team buffs. Running an ATK% Sands is much easier with this weapon in hand.
- Symphonist of Scents (5-star): A strong 5-star option with ATK-focused passives. Great for maximizing the buff value she provides to teammates.
- Calamity Queller (5-star): Another solid ATK weapon that works well if the above are not available.
- Favonius Lance (4-star) – Best Free-to-Play Option: Generates Elemental Particles on CRIT Hits, helping Iansan and the whole team recharge energy faster. Especially useful in energy-hungry team compositions.
- Skyward Spine (5-star): A decent Energy Recharge weapon if Engulfing Lightning is not available.
- Missive Windspear (4-star): A solid free event weapon with good Base ATK and ATK% substat. Worth using if you have it from its past event, though it lacks the ER utility of Favonius.
Best Artifacts for Iansan
- Scroll of the Hero of Cinder City (4-piece) – Best in Slot: As a Natlan character, Iansan can fully utilize this set’s 4-piece effect, which provides Elemental Energy on Nightsoul Bursts and grants allies a 12% Elemental DMG Bonus for the elements involved in reactions she triggers. This is her default and highly recommended set in almost all teams.
- Noblesse Oblige (4-piece) – Best Alternative: If another teammate is already running Scroll of the Hero of Cinder City (since duplicate set buffs do not stack), switch Iansan to Noblesse Oblige. Its 4-piece bonus raises all party members’ ATK by 20% after she uses her Burst.
- Tenacity of the Millelith (4-piece): Another decent option that provides a similar ATK boost while also increasing Shield Strength for characters who use shields.
Artifact Main Stats
- Sands: ATK% (or Energy Recharge if not using Engulfing Lightning)
- Goblet: ATK%
- Circlet: ATK%
Artifact Sub-Stats Priority
- Energy Recharge (until threshold is met)
- ATK%
- Flat ATK
- CRIT Rate (especially useful if running Favonius Lance)
Energy Recharge Requirements
- No Electro teammates: Aim for around 200%+ ER
- One Electro ally: Around 160–180% ER
- Two Electro allies: Around 140–160% ER
- With C1 unlocked: Requirements drop noticeably across all setups
Iansan Talent Priority
- Elemental Burst – Top Priority. This is the heart of her entire kit. Level it as high as possible first.
- Elemental Skill – Second Priority. Only worth investing in if you have unlocked C3, which raises the cap to Level 15.
- Normal Attack – Skip entirely. Iansan almost never attacks normally in a proper rotation. Do not waste materials here.

- Mora: Farm from Golden Ley Line Blossoms
Best Teams for Iansan in Genshin Impact (Version 7.0 Updated)
Iansan’s buff scales with how much the active character moves. Mobile DPS characters are her best partners. Here are the best team compositions as of Version 7.0, including new options from the Snezhnaya era.
Varesa Overload Team (Best Team)
This is Iansan’s strongest team. Varesa naturally moves a lot with her plunging attacks and dashes, which keeps Iansan’s Nightsoul Points maxed and the ATK buff at full strength. Electro Resonance also reduces Iansan’s Energy Recharge needs. Chevreuse reduces enemy Electro and Pyro resistance, and Mavuika adds heavy Pyro sub-DPS damage. This team clears the hardest content in the game comfortably.
Mavuika Hypercarry Team
Mavuika has the highest base ATK in Genshin Impact, which means Iansan’s percentage-based ATK buff hits extremely hard here. Her wide-sweeping attacks and dashes generate constant Nightsoul Points for Iansan. Bennett adds a flat ATK boost and healing, while Chevreuse reduces enemy Pyro and Electro resistance for the Overload reaction. A reliable and powerful setup for Mavuika mains.
Kinich Burning Team (New in 7.0 Meta)
Kinich is a highly mobile Dendro DPS who swings constantly during his Elemental Skill, making him an excellent partner for Iansan. His movement naturally generates Nightsoul Points, keeping her ATK buff active. Iansan and Bennett are among the best support options for Kinich since he scales primarily with ATK. Mavuika provides Pyro for Burning while Emilie further capitalizes on the reaction. This is a strong and flexible team that has gained traction in the 7.0 meta.
Sandrone Stellar-Conduct Team (New in 7.0 Meta)
- DPS: Sandrone
- Sub-DPS: Yae Miko
- Support: Iansan
- Support: Flexible slot (Zhongli, Qiqi, or a second Electro)
Sandrone, released in Version 6.7, is the first character to enable the new Stellar-Conduct reaction in Genshin Impact. This reaction requires Electro and Cryo application and deploys a Polestar Field that buffs Cryo and Electro DMG for the whole party. Iansan fits into this team as an off-field Electro support, helping trigger reactions and providing ATK buffs to Sandrone who scales heavily off ATK. Yae Miko provides strong off-field Electro application and deals good damage of her own. This team is particularly relevant in 7.0’s Snezhnaya meta.
Clorinde Overload Team
Clorinde as main DPS benefits from Iansan’s mobile ATK buff, Chevreuse’s Pyro and Electro RES reduction via Overload, and Mavuika’s Pyro sub-DPS damage. Iansan provides the movement-based ATK buff while staying comfortably off-field. A solid Overload option for players who have Clorinde built.
Xiao Plunge Team
Xiao constantly plunge attacks and dashes, making him a great partner for Iansan’s movement-based mechanic. Vertical mobility from plunging also contributes significantly to Nightsoul Point generation. Faruzan reduces Anemo resistance and buffs Xiao’s Anemo DMG, while Furina adds further team damage. You can also replace Xiao with Chasca for a Natlan-friendly alternative.
Varesa + Xianyun Plunge Team
Xianyun enables Varesa’s plunging playstyle and provides healing. Furina further buffs team DMG output while Iansan adds ATK buffs. Both Xianyun and Iansan provide enough healing to balance Furina’s HP-draining mechanic. A high-ceiling team for Varesa mains.
Iansan vs. Bennett: Which Is Better?
This is the most common comparison players make. Both are 4-star supports with strong ATK buffs, but they work very differently:
- Bennett requires your DPS to stand inside a small circle to receive his ATK buff. Characters who move around a lot will frequently step out of it and lose the boost.
- Iansan’s buff follows the active character anywhere on the field. No need to stay in one spot, which makes her ideal for mobile DPS characters like Varesa, Mavuika, or Kinich.
- Bennett provides stronger flat ATK values and much better healing overall. He is also more universal and works with non-ATK scaling characters.
- Iansan provides higher percentage-based ATK buffs for the right DPS, adds healing without needing a healer slot, and avoids the zone restriction that limits Bennett’s value in active combat.
In short, Bennett is more universally useful, but Iansan is the better choice for mobile DPS characters where Bennett’s field is a constant problem. For Raiden Shogun, Yae Miko, or Keqing, Iansan can serve as a strong alternative or run alongside Bennett for double-buffing.
Iansan Gameplay Tips
- Keep your DPS moving. Iansan’s Nightsoul Points — and her ATK buff strength — depend on the active character covering distance. Always pair her with DPS characters who naturally dash, plunge, or sprint during their kit.
- Watch the Kinetic Energy Scale icon. When it shows a double exclamation mark (!!), your ATK buff is at full power. This is your signal that Nightsoul Points are maxed and your DPS is getting peak value.
- Use her Skill before her Burst. Thunderbolt Rush gives her Nightsoul Points immediately. Activating her Burst right after carries those points into the Kinetic Energy Scale, giving a stronger buff from the start of the rotation.
- Stack ATK above 2500 if possible. Iansan’s buff scales off her own ATK, so the higher it is, the stronger the bonus she gives to allies.
- Stay off-field as much as possible. After activating her Burst, switch immediately to your main DPS. Her C2 constellation grants an extra 30% ATK buff specifically when she is off-field and Precise Movement is active.
- Vertical movement counts too. Plunging attacks and jumps also contribute to Nightsoul Point generation. Characters like Xiao or Chasca who plunge constantly are excellent partners for this reason.
- Prioritize her Burst talent only. Everything Iansan does in combat flows through her Elemental Burst. Leveling anything else first is a waste of materials at any stage of the game.

Is Iansan Worth Pulling?
Yes — even more so now in Version 7.0. Here is why:
- She is a 4-star, which means her constellations are accessible over time through regular pulls and standard banners.
- Her C0 kit is already strong, and C2 pushes her well above many 5-star supports in ATK buffing.
- Her team flexibility has expanded in 7.0. She fits into Varesa, Mavuika, Kinich, Clorinde, Sandrone, and Xiao teams — all strong, widely used compositions.
- She adds healing on top of buffing, reducing the need for a dedicated healer in many setups.
- Her mobile buff mechanic makes her especially valuable as Natlan and Snezhnaya DPS characters continue to use movement-heavy playstyles.
The only situation where she underperforms is when paired with stationary DPS characters who do not move much during combat. For most active combat builds, she remains one of the best 4-star support options in the game.
How to Get Iansan in Genshin Impact
Iansan is available at a normal rate on all active banners except the Beginner’s Wish. She can be obtained on limited event banners when she appears as a rate-up 4-star, and she is also available from the standard Wanderlust Invocation banner. Her most recent rate-up was during Version 6.2.
You can play Genshin Impact for free on the following platforms:
- Official Genshin Impact Website
- Android – Google Play Store
- iOS – Apple App Store
- PlayStation
- PC – Epic Games Store
- Xbox
Wrapping Up
Iansan has only gotten better as the game has evolved. From her debut in Version 5.5 to the current Version 7.0 Snezhnaya meta, her mobile ATK buffing system remains one of the most unique and valuable support kits in Genshin Impact. New DPS options like Kinich and Sandrone’s team environment further expand where she can be used effectively.
Build her with Scroll of the Hero of Cinder City, use Engulfing Lightning or Favonius Lance, max her Elemental Burst talent, and pair her with a high-mobility DPS. That combination will carry you through Natlan, Snezhnaya, and whatever content comes next.
