Iansan
Iansan is one of the most worthwhile buffers to invest in for hypercarry, Overload, and Aggravate teams, and she pairs especially well with Natlan's mobile carries and plunge attackers. Her ATK buff can rival Bennett's without demanding a specific element. What matters most is a 4pc Scroll of the Hero of Cinder City and enough Energy Recharge to keep her Burst up. The weapon is relaxed: a 4-star Favonius Lance batteries the team while topping up energy. Farm ATK% and hit your ER requirement first.

Teams for Iansan
Iansan's talents
Weighted Spike
Performs up to 3 consecutive spear strikes.
Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.
Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.
Nightsoul State: Swift Stormflight
While in the Nightsoul's Blessing state: Iansan's Charged Attack will be transformed into the formidable Swift Stormflight, consuming a certain amount of Stamina to stomp fiercely down, dealing Nightsoul-aligned AoE Electro DMG.
Thunderbolt Rush
After this Skill is used, Iansan will regain 54 Nightsoul points and enter the Nightsoul's Blessing state. Within 5s after this is done, using a Normal Attack will trigger 1 quick Swift Stormflight stomp from Iansan that will not consume Stamina.
Nightsoul's Blessing: Iansan
Continuously consumes Nightsoul points. If she runs out, or uses this Skill again, her Nightsoul's Blessing state will end. It has the following properties:
· Increases Iansan's Movement SPD.
· Holding sprint will switch Iansan to Rushing Thunderbolt mode, greatly increasing her Movement SPD temporarily. In this mode, Iansan can make flying leaps using terrain, or consume additional Nightsoul points to move on water or liquid Phlogiston while being immune to DMG from the latter.
"Faster, stronger! That's what all that hard work is for!"
The Three Principles of Power
When this Skill is used, Iansan will gain 15 Nightsoul points and enter the Nightsoul's Blessing state.
When the Kinetic Energy Scale leaves the field, Iansan's Nightsoul's Blessing state will end.
Kinetic Energy Scale
The Kinetic Energy Scale will follow the character around, boosting the ATK of your current active party member in different ways based on Iansan's Nightsoul points.
· If Iansan has less than 42 Nightsoul points, the ATK bonus will be based on her Nightsoul points and ATK.
· If Iansan has at least 42 Nightsoul points, the Kinetic Energy Scale will switch to the "Ardent Support!" state, in which the ATK bonus will be stronger and based on her ATK alone.
Additionally, the Scale will log the distance your current active character (excluding Iansan) has moved so long as it is active, restoring Nightsoul points to Iansan every second based on the distance moved in the previous second.
The Scale will disappear once her Nightsoul's Blessing state ends. It will also disappear after 1 second when you are not in a state of combat. While it is active, Iansan's Nightsoul's Blessing state will not end even if she is not on the field.
"Power is not about natural talent. Power stems from unceasing practice. Power must be exercised correctly."
Enhanced Resistance Training
During this time, her ATK is increased by 20%, and whenever she regains Nightsoul points through the Kinetic Energy Scale in her Elemental Burst, The Three Principles of Power, she will gain 1 extra Nightsoul point. Additionally, when your current active party member consumes or restores Nightsoul points, the extra Nightsoul points Iansan gains the next time she restores Nightsoul points via the Scale will be increased to 4. This effect can occur once every 2.8s.
"Precise Movement" will expire when Iansan's Nightsoul's Blessing state ends.
Kinetic Energy Gradient Test
During this time, when Iansan restores at least 1 Nightsoul point, she will heal your current active character for 60% of her ATK. This effect can be triggered once every 2.8s.
Night Realm's Gift: Hard Work and Drive
While in an area with Phlogiston Mechanics within Natlan, Nightsoul Transmission: Iansan can be used. When the current active character is sprinting or in movement modes caused by certain Talents, or at a certain height in the air, switching to Iansan will trigger the following: Iansan enters the Nightsoul's Blessing state and obtains 25 Nightsoul points. Nightsoul Transmission can be triggered once every 10s by your own party.
While in an area with Phlogiston Mechanics within Natlan, Iansan will not take fall DMG when using terrain differences to make leaps.
Caloric Balancing Plan
Combat Rotation
- Cast E (Thunderbolt Rush, 16s CD): dash forward dealing Electro DMG, gaining 54 Nightsoul points and entering Nightsoul's Blessing.
- Within 5s of casting E, land one Normal Attack to trigger a free Swift Stormflight stomp (no stamina cost).
- Cast Q (The Three Principles of Power, costs 70 Energy, 18s CD) while still at ≥42 Nightsoul points so it enters "Ardent Support" mode — a stronger ATK buff scaled off Iansan's own ATK instead of her points.
- The Kinetic Energy Scale appears, following your active character and boosting their ATK for 12s.
- Swap immediately to your main DPS to attack under the buff; the Scale tracks that character's movement distance and restores Nightsoul points to Iansan every second to extend uptime.
- Keep the main DPS on field until the Scale disappears (Nightsoul points run out or Iansan uses E again), then swap back to Iansan.
- Repeat the E-then-Q cycle on cooldown (16s/18s, once 70 Energy is available) to maximize the team's ATK buff uptime.
Iansan constellations
When Iansan is in combat and is in the Nightsoul's Blessing state, she will restore 15 Elemental Energy for every 6 Nightsoul points she consumes. This effect can trigger once every 18s.
When using the Elemental Burst The Three Principles of Power, Iansan will also gain the Precise Movement effect from her Ascension Talent "Enhanced Resistance Training" for 15s. Additionally, if Iansan is off-field while Precise Movement is active, she will also increase your current active character's ATK by 30%. You must first unlock the Ascension Talent "Enhanced Resistance Training" to access the above effect.
Increases the Level of Thunderbolt Rush by 3.
Maximum upgrade level is 15.
When the Kinetic Energy Scale is present, Iansan will gain 2 stacks of Surging Force after your current active character (excluding herself) uses their Elemental Burst. The stacks last until the Scale leaves the field, and Surging Force can be gained once per Scale summoning. Whenever Iansan restores Nightsoul points via the Scale, she will consume 1 Surging Force stack and restore 4 additional Nightsoul points.
Additionally, if her Nightsoul restoration from the Scale overflows, Iansan will gain 50% of the overflow the next time she restores Nightsoul points via the Scale.
Increases the Level of The Three Principles of Power by 3.
Maximum upgrade level is 15.
The Kinetic Energy Scale's duration is increased by 3s.
Additionally, when Iansan triggers Nightsoul point restoration, if there is any overflow, she will gain the Extreme Force effect, which increases the DMG dealt by your current active character by 25% for 3s.

Birthday
Happy birthday! Would you like to try my custom-made fitness cake? There's no cream or sugar, so it's low-calorie, and I added in some veggies and grains to balance out the nutritional profile. Most birthday cakes out there are dangerous things to have around. All they do is make sure your body fat percentage goes up every year along with your age...
Self-Introduction
Hello
Hi there, I'm Iansan from the Collective of Plenty, and I'm the most well-known fitness coach in my tribe. You look like you're in pretty good shape... do you work out, too?
About Iansan: Fitness Coach
Physical fitness has always been a big part of my tribe's culture. Young people even show off their muscles to each other as a friendly gesture. So obviously, if you want to call yourself a fitness coach around here, you've gotta have the goods, or no one will take you seriously. In my case though, I never actually set out to become a fitness coach. For years, I was just minding my own business, following my training plan, and then somewhere along the way people started taking notice. Suddenly, people were watching in amazement while I was working out. Then they started asking me for tips, and it just grew from there.
About Iansan: Height
Don't take me for a little kid — I'm just short, like all my ancestors before me. I guess it must be genetic... But thankfully, it doesn't affect my strength at all.
More About Iansan: I
Have you ever heard of the "Pilgrimage Victors Academy"? It's a training program I set up after my string of victories at the Pilgrimage. A lot of people assumed that I was blessed with superhuman strength — I guess it's not every day you see a short girl like me best everyone else in the stadium. But I wanted to show them that no, there's no mysterious force at work behind my strength, just years of consistent hard work. Join my training program and you'll see for yourself. It was a strange experience at the start, though... First, I had people reporting me as a scammer, despite the fact that the classes were free — then I took Mavuika's advice and introduced a fee, and suddenly the class was oversubscribed... Weird.
More About Iansan: II
Standard barbells are too large for me. They block my vision when I'm lifting them, and I almost injured a student once because I couldn't see who was around me. So, I got Xilonen to make me a custom barbell from a special material that has a good weight, but takes up far less space. It makes things so much easier. The only downside is that looks can be deceiving... people are always mistaking it for a toy. Once, I forgot to bring it home from the fitness club, and some new students spotted it on the ground. One of them thought he'd have some fun with it, but when he went to pick it up, it wouldn't budge and he ended up pulling a muscle in his back. The other students didn't believe him, and before long the rest of them had pulled muscles in their backs, too... I make sure to carry it with me everywhere now.
More About Iansan: III
My first foray into the science of nutrition came when I was recovering from an injury. Back then, people didn't have a very sophisticated idea of what a good training diet looks like — the general consensus was just "eat more meat." And for most of the fitness club, that worked well enough. They're the kind of people who can devour entire platters of grilled meat in one sitting. But at my size, I could never fit that much food in me, so I was already on the market for a more efficient way of meeting my nutritional needs. Since I was stuck at home recovering for a while, I borrowed some reading material to research various ingredients and started experimenting in the kitchen, trying to cook some meals to support my training goals. After several failed attempts, I finally found a recipe that worked for me, and it was game-changing. Not only did it speed up my recovery, it also helped me to break my bench press record. My only regret is that, despite sharing it around, it's still relatively unknown outside the fitness club.
More About Iansan: IV
After I became head coach, I introduced a challenge for newcomers to the club — pick an exercise of your choice, and go head-to-head against me. Of course, it always ends the same way — after the newcomer collapses from exhaustion, I pick up their weights and continue for another ten to twenty sets of quality reps. My goal isn't so much to show them who's boss as to give them a taste of what serious training actually looks like. You get a lot of people joining the club who just want to ego-lift and show off, so it's my job to hammer home to them that fitness is hard work, not fun and games.
More About Iansan: V
Wrestling tatankasaurs is a longstanding tradition in my tribe, and winning is seen as a great honor. I decided to give it a shot after I'd been training for a while, but failed several times over, and the experience left me doubting my entire approach to training. Then, a short while later, the chief of the tatankasaurs suddenly flipped and went on a rampage through our settlement. Amid the chaos, I found myself standing between the saurian and a little girl who hadn't managed to escape in time. I had to save her... so I confronted the tatankasaur chief head-on. Somehow, knowing that she was right behind me and needed my protection helped me find a strength within me that I never knew existed. I wrestled with all my might, and I threw that tatankasaur onto its back. That was the day I learned to trust in my training approach again. I realized that training does steadily build your strength over time, but to summon your full strength, you have to call on it from somewhere deep in your soul.
About Us: Travel Experiences
I heard that you've traveled all over the world, and explored domains that few people have ever seen. It sounds amazing... Would you have time to tell me more about some of those experiences? Sometimes, what my students really need is the right inspiration, and I think your tales of braving the unknown and conquering adversity would be perfect for that.
About Us: Motivating Each Other
As a coach, I'm often expected to give advice to other people, but I actually prefer to work in a team where we all motivate each other. Fitness is a lifelong endeavor, and like with anything, going it alone for too long leads to burnout — even for me. You're my friend, so could I ask you to be my motivation buddy? If there ever comes a day when I give in to the temptation to laze around and eat candy, I'll need someone by my side with the courage to call me out on it.
Thoughts About Other Characters
Citlali
I have a lot of respect for Granny Itztli, but... I can't say I agree with her lifestyle choices. I used to think she was a fellow early riser, because I'd always see her up and about on my morning runs — turns out she'd actually stayed up all night and was finally heading home to sleep... And she's been living like that for what, 200 years? How her body hasn't given out on her by now, I'll never know. The shamans in that tribe are just built different, I guess.
Mualani
Mualani has always impressed me. She's never taken any formal fitness training, and yet her strength and physique are better than most of the students I've had. She actually did sign up for a class once upon a time, but never ended up coming along. Maybe water sports are just more effective at inducing all-round muscle development? Who knows, but I suspect the key is her frame of mind. As far as I know, she's never gone out and trained with the specific goal of achieving a certain kind of body.
Xilonen
Xilonen is the first friend I ever made from the Children of Echoes. I have all sorts of new ideas when I'm designing fitness equipment, and she's one of the few people who can actually bring them to life. And not just that, but the build quality is always exceptional. My only issue is that she always pushes back on my deadlines... but I guess if you want something done well, it takes the time it takes.
Mavuika
Because of the childhood I had, I don't like relying on other people or needing their protection. But when Mavuika is around, even I feel comfortable letting her take the lead. To be clear, that's not because she's the leader and I'm intimidated by her. Quite the opposite. It's because I trust her as a close friend. Following her just feels right... almost instinctive, like moving towards the light when you're surrounded by darkness.
Kachina
Kachina's a very special student. Mostly because of the sheer number of classes she's attended over the years... So many times, I've watched her nervously walk into the stadium, only to leave later looking crushed and defeated. Then she comes to find me to apologize for her poor performance — although honestly, I feel like I've failed her by not delivering on the promises I make in my advertising. Anyway, since then, I've waived all her fees, and told her she can train with me whenever she wants. I see huge potential in her, but I know she has her own issues... I've done all I can do as a coach, so whatever other challenges she faces, she'll have to conquer them on her own.
Kinich
Kinich always does a great job whenever I need someone to hand-pick the best fruit from Varesa's orchard. Working with him would be a joy — if it weren't for that little monster he hangs around with... He says the nastiest things. Someone really needs to teach him some manners. I'd very happily do that myself, of course — I'm sure one of my training programs would whip Ajaw into shape — and in fact I've offered that to Kinich before. But, he turned me down. I guess he has his own way of keeping Ajaw in line.
Varesa
Ah, Varesa... She's my star student, my pride and joy. I hope she hasn't made a bad impression on you... Oh — no, not like that. When push comes to shove, I'm sure she pulls her weight in battle, and I know she has things under control at the end of the day. It's just, she can be a little... too relaxed, you know? I feel like if I'm not there constantly pushing her to stay focused, she'll lose all sense of time and treat every day like she's on vacation. Leave the house to run an errand, but then saunter along without a care in the world, letting herself get distracted by every morsel of food she passes along the way... Once in a while that's fine, but you can't live like that when you're out adventuring, and the stakes are so high! Anyway, I've told her all this before, so hopefully I've gotten through to her by now. But... the other thing that worries me is the amount of food she needs. I mean, you tell me — is it really practical to go hiking through the hills with a sack of food on your back the size of a baby tatankasaur?
Varesa
My biggest concern for Varesa right now is that her energy management seems out of control. Her metabolism seems like it's stuck on a high-burn mode, meaning she wastes an awful lot of energy, and I suspect that's the cause of her alarming appetite. I do hope she takes some time to look into what makes her this way. I'd love to see her gain the ability to manage her energy expenditure a little better, so she doesn't need to eat like a horse every single meal... I mean, it's nice to see her thoroughly enjoy her food, but at the same time, I want to urge her to be more mindful of what she's putting in her body. It's never a good idea to just gorge yourself — you have to pay attention to nutrition and quantity, and especially limit your fat and sugar intake. Much better to get her diet under control now than have to deal with the consequences when she develops health issues later in life.
Hobbies & Personality
Iansan's Hobbies
Researching training methods, designing training equipment, developing high-nutrition training meals... In a nutshell, training.
Iansan's Troubles
I hate being short. Not because I dream of being tall and athletic-looking though, it's just inconvenient. Like, whenever I'm teaching a group of students, I have to stand on a stool. Otherwise, when I demonstrate the proper technique, the students at the back won't see.
Favorite Food
My favorite food is... Hmm, honestly, I don't really have a favorite. I'm more concerned about the calories and the nutritional profile of what I eat. Taste is a secondary concern.
Least Favorite Food
Deep-fried food and ultra-processed food... I know, that pretty much rules out most of what the rest of the world considers delicious. I know it all tastes good, and I have no problem with that, but if you look at the calorie content and the nutrient density, all that stuff is just awful.
Feelings About Ascension
Feelings About Ascension: Intro
The key to effective fitness training is sound methodology. Namely, gradual progression and science-backed nutrition.
Feelings About Ascension: Building Up
Any fitness enthusiast who puts blind faith in perseverance alone will end up getting injured — I learned that the hard way. Pushing yourself to take on more than you can comfortably bear will just lead to two fractured arms and weeks of recovery in isolation. The right outlet for your perseverance is to stick doggedly to the right training methods.
Feelings About Ascension: Climax
A younger me would get all excited whenever I added another push-up to my personal record, but that rarely happens these days. I've come to realize that as long as I stay consistent with my training, progress is the inevitable outcome whether I see it or not.
Feelings About Ascension: Conclusion
Maybe this was all a test I had to go through, to prove myself worthy of my ancient name. Either way, those words spoken by my ancestors ring true to this day: "No matter what strength one is born with, true strength must be toiled for."
Receiving a Gift
Receiving a Gift: I
Great choice. Good amount of calories, nutritionally balanced — exactly the kind of thing I eat when I am training. I actually have a slightly improved version of this recipe, though. Let me know if you ever want to try it.
Receiving a Gift: II
Aw, thanks. This is a very popular dish, although the calories are a little high, so it's not really something I go for... Sorry, I'm pretty strict with what I eat. Diet's one of the most important parts of any fitness regimen.
Receiving a Gift: III
Oh goodness... Everyone should stay away from calorie bombs like these! Athlete or not, this kind of thing is disastrous for your health!

Strengths & Weaknesses
- Can restore HP for the team via Kinetic Energy Gradient Test.
- The core mechanic (via The Three Principles of Power) scales with ATK — the standard stat line on most damage weapons, no build pivot needed.
- 4★ (Polearm) — obtainable via the standard wish/banner, no need to pull on a limited banner.
- The Normal Attack (via Weighted Spike) already deals innate Electro DMG from the start — no need to wait on the Elemental Skill to apply the element.
- Since it scales with ATK (via The Three Principles of Power), it competes for high-ATK weapons/ATK% pieces with other ATK-based DPS on the team — no niche-stat advantage.
- The ascension stat is just plain ATK% — no built-in CRIT/EM/DMG Bonus advantage like many other characters, everything has to be rolled from scratch on artifacts.
Role Rankings
Machine-classified by scanning mechanic keywords in the OFFICIAL skill text (not another site's opinion ranking). Characters whose weapon type is inherently elemental (e.g. catalysts, bows) may not show "Does this well" for On-Field even if they can still be played on-field — this is a limit of text-based detection.
