Base Stats

Iansan is a 4-star Electro character who wields a Polearm in Genshin Impact. Her gameplay focuses on being a versatile ATK buffer and support, enhancing team damage through movement-based mechanics. Her Elemental Skill, "Thunderbolt Rush," allows her to perform swift strikes, applying Electro damage and generating Nightsoul points. Her Elemental Burst, "The Three Principles of Power," grants an ATK buff to all nearby allies, scaling with Iansan's ATK and influenced by her Nightsoul points. Lore-wise, Iansan is a renowned fitness trainer and nutritionist from the Collective of Plenty in Natlan, known for her undefeated record in the Pilgrimage of the Return of the Sacred Flame and her mentorship to fellow contestants.

Iansan's Tier & Rating

What Kind Of Character Is Iansan?

Iansan is a support for ATK-scaling characters that relies on Nightsoul points amount and her own ATK stat for her buff. Her Elemental Burst is the main focus of her kit since it has the buffing capabilities. Her Skill is a mobility Skill similar to other Natlan characters. Her buff relies on the displacement (movement) of characters.

Basics Of Using Iansan

Iansan is an Off-Field Support with a sizeable Attack buff and some healing on the side. Her Attack buff is provided by a Kinetic Energy Scale, which is summoned after activating her Elemental Burst. Iansan also has a Nightsoul Blessing due to being a Natlan character, and the Nightsoul points she gains is tied to her Attack buff.

Elemental Burst Records Distance Traveled

Iansan's Elemental Burst has a unique mechanic that records the distance your active character travels while her Attack Buff is active. This includes dashing and plunging. Iansan's Nightsoul points will continue to be restored provided the On-Field DPS keeps moving, It's important to note that the scale consumes 6 Nightsoul Points per second, and the scale disappears once she fully consumes all her points or after the full duration ends.

More Nightsoul Points Strengthens Her Attack Buff

When Iansan has at least 42 Nightsoul points, the Kinetic Energy Scale will provide an Attack boost that is a good fraction of her total Attack stat. Conversely, when she has less than 42 Nightsoul points, the buff instead accounts for only a small percent of her Attack per Nightsoul point.

This makes it so that gaining Nightsoul Points by being paired with very mobile DPSes (like Natlan characters) allows her to maximize her buff. However, she can still provide a decent buff if you supply Iansan with enough Attack to compensate for the lower scaling.

Some Healing Provided

Iansan has a bit of healing every time she restores a Nightsoul point. This heal is based off of her Attack. It usually isn't going to be enough to be the sole sustain you have in a team, and is just a nice add-on to her already significant Attack buff.

Roles & Playstyle Of Iansan and Its Strengths and Weakness

Support Iansan

Iansan is an ATK-buffing support that requires lots of movement from the On-Field character. Different from Bennett, her Elemental Burst doesn't have the restrictions of a circular range but her healing is almost nonexistent. However, she is still a welcome addition for ATK-buffers.

Pros and Cons of Support Iansan

Best Build for Iansan

Iansan wants to be built around getting as Attack as possible to maximize her buff. Alongside this, as a Natlan character, Iansan is an effective user of the Scroll of the Hero of Cinder City set. She'll generally perform at her best alongside Natlan DPSes. See below for the recommendations.

Stat Goals For Off-Field Support Iansan

Iansan works best with mobile DPS units who can keep restoring Nightsoul points for her. Escoffier’s signature weapon is her best option thanks to its strong ATK bonuses and how easily she triggers its passive. But it's likely better on Escoffier herself if you have her.

Iansan’s Energy needs vary with her team, weapon, and Artifacts. More Electro teammates lower her ER needs. Using Favonius Lance and having the 2-piece effect of the Cinder City set active also helps manage her Energy.

Best Weapon for Iansan

Iansan's weapon choices will typically be the ones that gives Energy or Energy Recharge% or generous amount of Attack increases.

Premium Weapons for Off-Field Iansan

	Weapon	How to Get Rating
Best	Symphonist of Scents	Get from Limited Banners - Increases user's Attack and provides additional Attack when the user is off-field. - When the equipping character heals, the party including the user gets a significant Attack boost. - It doesn't give Iansan Energy but the generous amount of Attack buffs it has in the passive, which Iansan can easily trigger. - Compensate the lack of Energy Recharge% through her artifacts with this weapon.
2nd	Calamity Queller	Get from Limited Banners - Another weapon that has a lot of Attack increases. - Iansan can easily meet the conditions of the passive. - Does not give Energy, so compensate by using an Energy Recharge% (ER) Sands and substats.
3rd	Engulfing Lightning	Get from Limited Banners - Attack increases according to user's Energy Recharge% over the base 100%. - Increases ER% after using Elemental Burst. - Really good option for Iansan, especially if she's in a team without another Electro teammate.
4th	Favonius Lance	Get from Banners - Energy Recharge% helps Iansan charge her Elemental Burst. - Passive provides Energy for everyone on her team including herself. - Iansan needs some CRIT Rate trigger the passive consistently.
5th	Skyward Spine	Get from Banners - Energy Recharge% stat can make it easier for Iansan to get her Burst back up whenever needed. - An alright stat stick due to the high Base Attack. - No further team utility, which lowers its rank against Favonius Lance, but it's something you can use if you don't have any other choice.

Any weapon that provides Energy Recharge% or ATK% bonuses will generally be very good choices for Iansan. Symphonist of Scents is the best overall, but will probably be more effective on Escoffier herself if you have her.

Note that the Energy provided by the Favonius Lance's passive lets Iansan generate Energy for the whole team too, further adding to her strong utility so long as you have enough CRIT Rate to ensure she triggers the passive. This weapon is at its best at R5, due to the increased chances of producing an Energy Particle.

Free To Play Friendly (F2P Weapons) for Off-Field Yaoyao

	Weapon	How to Get Rating
Best F2P (Event)	Tamayuratei no Ohanashi	Obtained From Past Event (Enchanted Tales of the Mikawa Festival) - Has an Energy Recharge% secondary stat. - Decent base Attack while also increasing Attack and movement speed 10 seconds after using Skill. - No longer obtainable if you didn't finish the event. - Best at R5.
2nd F2P (Event)	Missive Windspear	Obtained From Past Event (Of Ballads and Brews) - Similar to Tamayurutei in terms of base Attack and Attack boost passive. - Doesn't have an ER% secondary stat, which might make it harder to use when Iansan is the only Electro on a team. - No longer obtainable if you didn't finish the event. - Best at R5.
3rd F2P	Prototype Starglitter The Catch	Liyue Foregeable (Craftable) Weapon and from Fishing -Energy Recharge% stats can help Iansan use her Burst more consistently. - Accessible for every player since Prototype Starglitter is craftable, and The Catch is a reward from fishing. - Best at R5. - Won't be as good as other options, but usable until you get better weapons.

For Free-to-Play options, Iansan can make use of any of the event-only Polearms that give Attack. Tamayuratei no Ohanashi is slightly more favored due to the Energy Recharge% stat, but any weapon that gives Attack and/or Energy is viable on Iansan.

Iansan Best Artifacts

Iansan's Attack buff is already noticeably very strong, and her Artifact choices will have sets that can further increase her value as a buffer. See the recommendations below:

Artifact	Recommendation Details
Scroll of the Hero of Cinder City	★★★★★ - 2-pc. effect gives Energy when a nearby party member gives Energy, which helps Iansan charge her Burst faster. - the 4-pc. effect, when equipped on a Natlan character, gives a hefty amount of Elemental DMG bonus, which is a passive Iansan can easily trigger.
Noblesse Oblige	★★★・・ - Can be a good option due to the ATK% buff. - Good option if someone else in the party already has the Cinder City set equipped.
2-pc. Energy Gain 2-pc. ATK%	★★・・・ - This set or a combo of 2 piece Cinder City for the Energy and any 2 piece Attack set can be temporary setup while you farm for a better 4-piece set. - Helps Iansan with her Energy requirement while providing her more ATK% so her buff is more potent.

Recommended Artifact Stats

	Main: Flat HP Sub: HP% / Flat HP / Energy Recharge% / CRIT Rate / Elemental Mastery
	Main: Flat ATK Sub: ATK% / Flat ATK / Energy Recharge% / CRIT Rate (if equipped with Favonius Lance)
	Main: Energy Recharge% or ATK% Sub: ATK% / Flat ATK / Energy Recharge% / CRIT Rate (if equipped with Favonius Lance)
	Main: ATK% Sub:Flat ATK / Energy Recharge% / CRIT Rate (if equipped with Favonius Lance)
	Main: ATK% or CRIT Rate (if equipped with Favonius Lance) Sub: ATK% / Flat ATK / Energy Recharge%

ATK% Is as Important as Energy Recharge%

Iansan wants to have Energy Recharge% to be able to have her Elemental Burst up every rotation. But she also wants to have a high enough Attack stat so the buff she gives is significant. Aim to balance the two to get the most out of Iansan's kit. If she has the Favonius Lance equipped, she'll also want to be supplied around 50% or more CRIT Rate to be able to trigger the passive

Best Team Comp Iansan

Premium Mavuika Melt Team

Support	DPS	Support	Support
Iansan	Mavuika	Citlali	Xilonen
Details
- Iansan provides a generous ATK% buff for Mavuika. Either her or Xilonen can hold the Cinder City set, while the other can have Noblesse Oblige. - Mavuika is the main On-Field DPS who appreciates Iansan's ATK buff. The movement from her bike-mode easily meet the conditions for Iansan's Kinetic Energy Scale that records distance traveled. - Citlali is Mavuika's premiere support that allows her to Melt while providing Pyro shred. Citlali can instead equip Tenacity of the Millelith or the Instructor set in this team. - Xilonen provides more Elemental RES shred and further healing with her Elemental Burst. Either her or Iansan can hold the Cinder City set, while the other can have Noblesse Oblige

This is one of Mavuika's strongest team setups due to amount of buffs she gets with Iansan included. The faster Fighting Spirit generation can also make reaching Mavuika's fully charged Elemental Burst easier. Bennett can be a good and almost comparable alternative to Xilonen if you don't have her.

Other Team Comps For Iansan

Overload with Chevreuse and Varesa

Team		Detail
Iansan	Varesa	- Iansan's kit is very synergistic with Varesa due to the ATK% buff and how much Varesa moves between her plunges and Elemental Skill charges. - Chevreuse is key in Overload teams for her Pyro/Electro RES shred and DMG% bonus with C6. - Mavuika contributes her own DPS and a DMG% buff after using her Elemental Burst.
Chevreuse	Mavuika

F2P Friendly Team Comp

Team		Detail
Iansan	Xiangling	- A F2P friendly team comp that uses free characters or easily obtainable ones. - You can use Bennett on-field to generate Energy for Xiangling, whose Pyronado is the main source of damage. Xingqiu lets Xiangling's Pyronado trigger the Vape reaction, increasing its damage.
Xingqiu	Bennett

Team Rotation of Iansan and Combos

Basic Team Rotation for Off-Field Support Iansan

Iansan's regular combo at C0 will be an Elemental Skill, into a Normal Attack, into her Elemental Burst. At C2, she no longer needs to use the Normal Attack once, allowing her to use Skill into Burst like other Off-Field Supports.

How To Use Iansan?

Support That Uses ATK And Nightsoul Points To Buff ATK

Iansan is an ATK-scaling Support that uses her ATK stat to buff the DPS. She is more similar to Shenhe compared to Bennett and Sara since Iansan does not scale on base ATK. The amount of Nightsoul points she has also affects the buff her Elemental Burst gives to the DPS.

The biggest advantage of Iansan is that her buff follows the character and is not restricted in one location.

ATK Buff Provided is Based on Total ATK of Iansan

Iansan's buff gives 27% of Iansan's Attack to team mates. The max amount of buff Iansan can give the character is also limited by the talent level of Elemental Burst. The needed amount to maximize the attack buffs Iansan provides is fairly high so make sure to build your Iansan properly.

Needs to have 42 or More Nightsoul Points

Remember that the buff of Iansan greatly decreases when the Nightsoul Points is less than 42 points. Since Iansan recover points based on the movement of the characters, Varesa and other characters that moves a lot allows you to keep the buff of Iansan at best state.

▼ Ideal Characters for Iansan

Characters that Works Well with Iansan
Varesa	Kinich	Mavuika	Chasca

Have Healing but it is NOT enough to Sustain the Team

After triggering Nightsoul Burst, for 10 seconds, Iansan can heal the on-field character based on her Nightsoul Points. However, the amount healed is very low and only happens once every 2.8 seconds.

Amazing for Exploration

Iansan has a special Skill and Dash that allows her to sprint quickly. She is especially useful at Natlan.

Should You Pull for Iansan's Constellation Or Best Weapon?

C2 is a Good Stopping Point

Iansan's C2 is a good stopping point since it's a decent buff to her attack buffing capability while hopefully costing you less overall funds if you do not want to get the 5-Star character. The rest of the constellations are still good to go for, however, because of how they make her buff more consistent.
