Reflects patch 6.7 (2026-07-06) — the meta store re-ranks every patch, never edited by hand.
Is Nilou worth building?

Nilou doesn't hit much herself, yet she's the heart of one of the game's most explosive Bloom teams. The whole party must be Hydro and Dendro only, and in return your Bountiful Cores deal monstrous damage. Her build is dead simple: pile on HP% from start to finish, run 2pc Tenacity of the Millelith + 2pc Vourukasha's Glow, and push to level 90 for max HP. Don't waste resources leveling her talents or farming CRIT. Pair her with Nahida as the Dendro core and the team clears mobs almost unrivaled.

Nilou's talents

Dance of Samser
Normal Attack
Performs up to 3 consecutive sword strikes.

Charged Attack
Consumes a certain amount of Stamina to perform a twirling slash.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.
Dance of Haftkarsvar
Enters the Pirouette state, dealing Hydro DMG to nearby opponents based on Nilou's Max HP.
While she is in the Pirouette state, Nilou's Normal Attacks and Elemental Skill will cause her to enter the Sword Dance and Whirling Steps stances respectively, causing DMG she deals to be converted to Hydro DMG that cannot be overridden and that is considered Elemental Skill DMG.

In these stances, Nilou's third dance step will end Pirouette, and has the following effects based on the type of said dance step:
·Sword Dance: unleashes a Luminous Illusion that deals Hydro DMG to opponents it touches and grants Nilou the Lunar Prayer effect. This effect converts Nilou's Normal Attacks into Sword Dance techniques, and her final hit will unleash a Luminous Illusion.
·Whirling Steps: Nilou unleashes a Whirling Water Wheel that deals AoE Hydro DMG and creates a Tranquility Aura that follows your active character around and applies Wet to opponents within its AoE.

Nilou is unable to perform Charged Attacks when under the effect of Pirouette or Lunar Prayer. These effects will be removed once she leaves the field.

"Daintily her toes touch the water's face, and the light that ripples forth equals even the seven heavens."
Dance of Abzendegi: Distant Dreams, Listening Spring
Begins the dance of faraway dreams and springs that hear, causing a Lotus of Distant Waters to bloom, dealing AoE Hydro DMG based on Nilou's Max HP and applying the Lingering Aeon effect to all opponents hit.
After an interval, opponents affected by Lingering Aeon will take Hydro DMG.

"We have never witnessed that distant dream, but this dance can bring it to life."
Court of Dancing Petals
When all characters in the party are all Dendro or Hydro, and there are at least one Dendro character and one Hydro character:
The completion of the third dance step of Nilou's Dance of Haftkarsvar will grant all nearby characters the Golden Chalice's Bounty for 30s.
Characters under the effect of Golden Chalice's Bounty will increase the Elemental Mastery of all nearby characters by 100 for 10s whenever they are hit by Dendro attacks. Also, triggering the Bloom or Lunar-Bloom reaction will create Bountiful Cores instead of Dendro Cores.
Such Cores will burst very quickly after being created, and they have larger AoEs.
Bountiful Cores cannot trigger Hyperbloom or Burgeon, and they share an upper numerical limit with Dendro Cores. Bountiful Core DMG is considered DMG dealt by Dendro Cores produced by Bloom.
Should the party not meet the conditions for this Ascension Talent, any existing Golden Chalice's Bounty effects will be canceled.
Dreamy Dance of Aeons
Every 1,000 points of Nilou's Max HP above 30,000 will cause the DMG dealt by Bountiful Cores created by characters affected by Golden Chalice's Bounty to increase by 9%.
The maximum increase in Bountiful Core DMG that can be achieved this way is 400%.
White Jade Lotus
When Perfect Cooking is achieved on Food with Adventure-related effects, there is a 12% chance to obtain double the product.

Combat Rotation

  1. Field a team of only Hydro and Dendro characters (at least one of each) to meet the Court of Dancing Petals condition.
  2. Unleash her Burst (Q, costs 70 Energy) for AoE Hydro DMG scaling off Max HP, applying the Lingering Aeon delayed-damage effect.
  3. Cast her Skill (E, 18s cooldown) to enter the Pirouette state.
  4. Use Normal Attacks/Plunging Attack to complete all 3 dance steps while in Pirouette.
  5. Completing the 3rd dance step with a full Hydro+Dendro party grants the whole team Golden Chalice's Bounty for 30 seconds.
  6. Swap to another Hydro/Dendro unit to trigger Bountiful Cores for AoE burst damage while the buff is active.
  7. Rotate Nilou back in every time E/Q come off cooldown (about 18s) to keep refreshing the buff and Bountiful Core cycle.

Voice Lines & Comments

Official HoYoverse Fetter voice-lines — the character introducing themselves, commenting on allies, sharing likes and their birthday.

Birthday

Umm... Happy birthday! I learned a new dance, and I want to show it to you. Uh, am I nervous? *sigh* You saw right through me. It's because... I wanted to incorporate my feelings into the moves, but then the choreography just got more and more difficult... Anyway, I just wish that your life will always be full of wonder and happiness.

Self-Introduction

Hello

Hello, I'm Nilou from Zubayr Theater. We have one dance scheduled for today, and it's about to start — keep your eyes peeled!

About Nilou: Body Language

Sometimes, you can convey more with dance than words. If you don't know what to say, then just dance.

About Nilou: Dance and Wisdom

You need an extreme amount of talent to pursue knowledge and wisdom. Many people throw their entire lives into it, only to end up burned out and depressed... Dance isn't like that. You don't have to understand what you're seeing to enjoy watching it. If I can use my movements to demonstrate the beauty and meaning of dance, then I'm happy.

More About Nilou: I

Aaagh! Sorry, I'm trying to decide what to eat, and I got lost in thought. Hee-hee, do you need help with anything?

More About Nilou: II

My teacher taught me everything there is to know about dance, but she said that the most important thing is putting feeling into your movements. Only then can you move your audience and convey emotion. To express beauty, I must first become the embodiment of beauty.

More About Nilou: III

Sometimes, I receive letters from showgoers who say that my dancing has cheered them up. I always share this kind of happy news with everyone at Zubayr Theater. Even though I'm the one the audience sees on the stage, it's because of everyone's collective efforts that I can stand up there in the first place.

More About Nilou: IV

The Grand Bazaar occasionally hosts other kinds of performances, such as juggling showcases. I've tried juggling before, but I always end up catching the balls with my head... Mr. Zubayr and everyone else just laughed at me. They probably thought I had really good hand-eye coordination. Hee-hee, I've been exposed.

More About Nilou: V

Someone once told me that I was like a shining oasis that restored life and happiness to others with its warmth. That was nice of them to say, and I was happy to hear it, but... what I want to show people is much more than that. After spending so much time with you, though, I finally understand how it feels to have someone care for and look after you. Now... Now, I feel like that comparison is a far better one for you.

About Us: Dealing with Anger

Are you sulking? That's no good — c'mon, follow my lead. First, use your right hand to draw a biiig circle in front of you. Then, use both hands to take all those negative feelings off your chest and into the circle. Next, push it away as hard as you can! So? Feeling better now?

About Us: Going on Adventures

I've never left Sumeru City, but... I want to go on adventures with you. Going to new places will be fine as long as I can adjust... Umm, quick question: Inazuma's beaches won't have huge Wenut that'll suddenly jump out at us, right?

Thoughts About Other Characters

Cyno

I don't really like interacting with people from the Akademiya because they don't view the arts too kindly. I often wonder what they do when they're bored... Huh, Cyno plays Genius Invokation TCG? I can't believe it...

Tighnari

I hear he's a really talented botanist. He must be good at telling apart mushrooms. At least, he would never have to worry about eating a poisonous one... I'm so jealous.

Collei

She sometimes comes to watch my performances. She's a really hard-working Trainee Forest Ranger. One time, she warned me about getting lost. What did she mean by that? It's not like I've gotten lost before...

Kaveh

I heard he was the one who built the magnificent Palace of Alcazarzaray. He must have had a wonderful time making such a masterpiece, like when I'm in the middle of dance practice. Just thinking about dancing for everyone gives me so much happiness and motivation.

Dehya

It's hard to believe that so many things have happened recently... I wanted to pick out a good present for Dehya and Dunyarzad, but I just can't make up my mind. Everyone at the Grand Bazaar has given me many suggestions, but if I took them all, it'd be too much... What should I do...

Dori

The big-spending merchant Dori has watched me dance before. I remember that she talked with Mr. Zubayr once, and then never came back. Did something happen? ...Huh? She wanted me to go on tour around Teyvat? No way, Mr. Zubayr definitely would've refused for me! ...Ahh, please tell me he has...

Hobbies & Personality

Nilou's Hobbies

"My life is dance," or "Dance is my life"... Which phrase is the better way to describe it? Agh, I'm no good at logical things like this. Anyway, I'll just keep on dancing. I want to use my performances to show the beauty of art to more people.

Nilou's Troubles

I still can't tell poisonous mushrooms apart from non-poisonous ones... Apparently, color doesn't mean much — poisonous mushrooms can be bright or dull. Mmm, I feel like I understand, but I also don't...

Favorite Food

Sweets always make you feel better! Most people in Sumeru love them. Wanna try some? I'll get some for you!

Least Favorite Food

I have a hard time eating mushrooms, mostly because I'm scared... Not the type of scared that makes you want to run away, though! When I was little, I once ate a poisonous mushroom and was bedridden for days... If you want to eat any of Sumeru's mushroom dishes, please make sure to check that the ingredients are all edible!

Feelings About Ascension

Feelings About Ascension: Intro

Huh? What's this feeling...?

Feelings About Ascension: Building Up

I'm done warming up. I can do even better now!

Feelings About Ascension: Climax

I feel like I'm lying down on the back of a massive Anemo Slime. Ahh, it's so light and comfy~

Feelings About Ascension: Conclusion

I really like being with you. I don't know why, but it feels like a butterfly is trying to burst out of my chest... Anyway, how about I show a new dance to you?

Receiving a Gift

Receiving a Gift: I

This must be what it feels like to have flavors dancing on your tongue... How wonderful!

Receiving a Gift: II

Thank you. You must have put a lot of love and effort into this dish, just like I put so much of me into my dance practice.

Receiving a Gift: III

Sorry, my appetite's been a bit off lately. Please don't take offense.

Strengths & Weaknesses

Strengths
  • This kit's mechanic scales with the character's own HP, with a clear cap per the official formula (see the recommended stat goal below).
  • The core mechanic (via Dance of Haftkarsvar) scales with HP — HP% is also an easy-to-find substat, and the character usually comes with high survivability too.
Weaknesses
  • This mechanic's payoff depends on the character's own HP — falling short of the recommended goal below wastes part of its potential.
  • Needs Dendro · Hydro teammates in the party to fully trigger Court of Dancing Petals — flexibility is constrained by team elemental composition.
  • Since it scales with HP (via Dance of Haftkarsvar), it can't share ATK%-geared artifacts with other DPS — needs a separate HP-focused artifact/weapon set.
  • The ascension stat is just plain HP% — no built-in CRIT/EM/DMG Bonus advantage like many other characters, everything has to be rolled from scratch on artifacts.
  • 5★ (Sword) — only available on limited/character-specific banners, not on the standard wish.

Recommended Stat Goal

  • HP ≈ 50.000 — For every 1.000 HP, Frostbreaker's Melody adds 0,6% (capped at 30%) — derived goal: roughly 50.000 HP to hit that cap.

Recomputed from the official formula itself (not a third-party recommendation).

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.
