Version 5.5 Release Date and Details

Iansan Best Builds

Build for Maximum ATK and Energy Recharge

Iansan's ATK buff can be increased solely by her ATK stat, which means prioritizing it is a must if you want to get the best mileage with Iansan and her buffs.

Energy Recharge is taken for convenience so that Iansan can reliably burst off-cooldown. Iansan is expected to have similar energy requirements to Bennett and Xilonen.

Electro Buffer Support

Best Weapon	Engulfing Lightning
Replacement Weapons	1. Calamity Queller 2. Tamayuratei no Ohanashi 3. Favonius Lance
Best Artifacts	Scroll of the Hero of Cinder City x4 Noblesse Oblige x4
Artifact Main Stats	Sands: Energy Recharge or ATK%
	Goblet: ATK%
	Circlet: ATK%
Artifact Sub Stats	Energy Recharge, ATK%
Sample Teams	Hyper: Hyper:

When building Iansan as a support, you either pick the specialized Cinder City set for Natlan characters, or run Noblesse Oblige as a generalist option.

Using a combination of ATK and Energy Recharge weapons and artifact main stats allows Iansan to have formidable buffs with more convenient uptime on it.

Stat Value Recommendations

Stat	Recommended Value
Energy Recharge	200%+
Energy Recharge w/ Electro Teammate	160%+
ATK	2500 or above

Due to Iansan being a buffer support that requires her Elemental Burst to be up at nearly all times, we first hit the minimum Energy Recharge she needs to reliably Burst off-cooldown, then boost her ATK as high as possible for better buffs.

Take note that Iansan needs less Energy Recharge when paired with another Electro teammate, going from the initial minimum of 200% all the way down to 160%.

Iansan Best Artifacts

Iansan Uses Supportive Buffer Sets

For Iansan, playing her as a buffer means taking advantage of 4-pc. sets such as Scroll of the Hero of Cinder City or Noblesse Oblige, depending on whichever is needed or lacking in the team.

Otherwise, you can use 2-pc. ATK or ER combinations while working towards one of the 4-pc. sets.

Iansan Artifact Rankings

Use ER or ATK Weapons for Iansan

Iansan's weapon choices are more flexible, favoring weapons such as Engulfing Lightning or Calamity Queller for their main stats and helpful effects.

Otherwise, she can also make use of the Tamayuratei no Ohanashi event weapon, or opt for the standard Favonius Lance or Prototype Starglitter.

Iansan Best Team Comps

Universal Buffer Support

Iansan's main strength when teambuilding is being able to provide substantial ATK buffs to her team, which benefits most DPS units in the game.

On that end, she can slot into a near-endless variety of teams so long as the main receiver of her buffs is a DPS character whose damage also scales off ATK and CRIT.

Iansan Buffer Support Teams

Support	Main DPS	Sub-DPS	Sub-DPS/ Support
Iansan	Mavuika	Citlali	Xilonen
Iansan	Varesa	Furina	Xianyun
Iansan	Kinich	Mavuika	Thoma

Iansan generally works best when used as a raw buffer unit rather than for any Electro reaction potential she brings.

In these teams, Iansan is mainly focused on amplifying the damage of the Main DPS while keeping her own abilities up with enough investment into both ATK and Energy Recharge.

Iansan Aggravate Teams

Support	Main DPS	Sub-DPS	Sub-DPS/ Support
Iansan	Varesa	Nahida	Baizhu
Iansan	Clorinde	Nahida	Baizhu

Due to being an Electro unit, Iansan is an eligible member for most Dendro-related teams, especially if the main damage dealer can benefit off Iansan's ATK buffs.

Iansan Overload Teams

Support	Main DPS	Sub-DPS/ Support	Sub-DPS/ Support
Iansan	Mavuika	Fischl	Chevreuse
Iansan	Raiden	Sara	Chevreuse

Iansan can also slot into Overload teams with the correct carries, as her ATK buffs are generally helpful for the usual DPS units that are present in Overload.

Iansan Electro-Charge Teams

Support	Main DPS	Sub-DPS	Sub-DPS/ Support
Iansan	Ayato	Ororon	Kazuha
Iansan	Tartaglia	Ororon	Sucrose

As an Electro unit, Iansan is also able to facilitate Electro-Charge procs with her Elemental Skill, but still mostly serves as a buffer in these teams.

Iansan Superconduct Teams

Support	Main DPS	Sub-DPS	Sub-DPS/ Support
Iansan	Eula	Raiden	Mika
Iansan	Freminet	Fischl	Mika

Due to Iansan's buffs being ATK-based, she can specifically aid Superconduct teams as most of their carries scale off the ATK stat.

Iansan Kit and How to Use

How to Buff With Iansan

When buffing with Iansan, her Nightsoul Points are directly responsible for how effective her ATK buffs are, with the points only being increased via movement from other party members during her Elemental Burst.

With this, trigger Iansan's Elemental Burst, then switch to another party member that frequently moves around the battlefield to increase her Nightsoul Points and potentially gain maximum buffs from Iansan.

Elemental Skill Dashes Forward and Strikes

Iansan's Elemental Skill allows her to dash forward and strike the ground near the enemy, dealing AoE Electro DMG.

This seems to be used as a general damage tool and as a way to regain Elemental Energy with the amount of particles generated.

Can Be Held to Sprint At Great Speeds

Similar to most Natlan characters, Iansan is able to use a portion of her kit for general traversal, using up Nightsoul Points and then Phlogiston if it is available.

As a Collective of Plenty member, Iansan can hold her Elemental Skill to sprint across terrain, breaking obstacles in her path, perform leaping jumps, and tread across water.

Elemental Burst Provides Attack Boost

Iansan strikes the area around her, dealing AoE Electro DMG and summoning a Kinetic Energy Scale that follows the active character around.

For the duration of her Elemental Burst, this Kinetic Energy Scale raises the active character's ATK by a portion of Iansan's own ATK.

Gives Stronger Buffs With More Nightsoul Points

Iansan's Elemental Burst scales not only on her ATK, but also the amount of Nightsoul Points she has since her ATK buff's potency is based on how high her Nightsoul gauge is.

Rewards Frequency in Movement

Iansan gains Nightsoul Points through the movement of other active characters that is not her, meaning fast-moving DPS characters such as Mavuika or Kinich can take advantage of this for bigger buffs.

Vertical scaling characters such as Gaming and Xiao can also contribute to Iansan's Nightsoul Point acquisition, making her quite flexible for team comps.

Passive Talent Provides Healing Through Nightsoul Bursts

Iansan's "Warming Up Effect" allows her to regenerate the active character's HP over a period of time when a Nightsoul Burst is triggered, allowing her to provide some healing to the team.

Hailing from the Collective of Plenty

Iansan's tribe in Natlan is the Collective of Plenty and revealed to be a fitness instructor. The tribe is noted to be located by the volcano west of the region.

Thoughts About Iansan

Character	In-Game Thoughts
Chasca	I've always felt that training oneself and training others are two very different skillsets. Very few people have them both, but Iansan has them in spades. I, for one, am not very good at teaching other people. Whenever I'm trying to demonstrate something to the flying squad, I spend forever trying to explain some basic, boring detail that seems intuitive to me... only to have everyone ask, ''What's intuitive about that!?'' If only Iansan could tutor them, I bet we'd have twice as many candidates pass the flying trials each year... Shame that her training program doesn't include flying.
Citlali	I don't know her that well, but I do know light novels... Someone who's that powerful despite her size must have some kind of power-up that she uses to shoot up to seven feet tall and fight with 200% strength.
Kachina	Before, when I wanted to become stronger, I asked lansan to train me. She had me do all sorts of high-intensity workouts, and I often only managed to get through them by pushing myself to the limit. Luckily, she always knew just the right amount of training for me, so I still had just enough. energy to make my way home after each session... I'm really grateful to her.
Kinich	Kinich: I've taken jobs from her before. More of a long-term collaboration, really... She makes fitness meals for her personal-training students, with everything measured out to the exact calorie. To keep this up, she needs a steady supply of fruits that meet her strict quality. standards and size requirements. A single bruise or bug bite, and she'll reject the entire batch. Most people find this impossible to work with, but I've got a good eye for these things... plus a reliable means of disposal for fruits that don't make the grade. Ajaw: Wait, what? ... THAT'S what you make my juice from!?
Mavuika	Being Targeted: A lot of people underestimated lansan during her first few Pilgrimages after receiving her Ancient Name, and singled her out during the team stage as an easy target. Even though she never lost, the constant challengers drained her stamina and affected her ranking, which only made people more likely to target her... Proving Yourself: My advice to her was this - people are less likely to mess with someone whose strength is undeniable, so all she needed to do was to prove it. Well, she decided to do just that... by challenging me in the arena, hahaha. Yeah, I definitely didn't see that coming! In the end, she put up quite the fight, and no one underestimated her again..
Mualani	Iansan is the pride of the Collective of Plenty and all of Natlan. She's been part of so many Pilgrimages, and is still unbeaten to this day! I registered for her training class, actually, paid the tuition fee and everything. I just haven't started because, uh... I've been too busy to train... Okay, fine. I'll admit... When I saw what looked like when she finished her training, I heard a voice inside me say, "Hey, you belong in the water. Stay dry on land for too long, and you'll wind up stranded there." Sometimes, you've just gotta listen to your heart!
Ororon	Iansan is a famous sports coach, and well... All I can say is, I'm grateful the Pyro Archon didn't send her after me. I may have an advantage when it comes to height, but I'm pretty sure she can outrun me... Oh, the smoke-cloud trick? Heh, after you use it a bunch, people start to see it coming.
Xilonen	I once helped the Collective of Plenty make a couple sets of super heavy weight plates and dumbbells. When it was time for the goods to be picked up, Iansan came with a group from the tribe to inspect the finished products. She picked up and checked every single weight before placing them one by one into a cart. After lifting all those weights, she was barely winded, and her face was only a little red. To be honest, I'm a little jealous of them. Not only are they really strong, but they've also got a way with plants...
