The best Nilou build in Genshin Impact (Version 7.0) is Key of Khaj-Nisut with Heart of Depth, HP% sands, HP% goblet, HP% circlet. Updated August 28, 2026

How this build was derivedNilou’s kit multiplies HP, read from the scaling rows on the Elemental Skill and Burst rather than from the ability prose. Weapons and artifact sets below are ranked on whether their stat and their passive text act on that stat. This is a reading of the game’s own numbers, not a community tier consensus — a set that wins a niche team composition will not show up here.

Nilou build summary

Updated August 28, 2026

Key of Khaj-Nisut is the closest fit on the game's own numbers: Nilou's kit multiplies HP, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Primordial Jade Cutter, Serenity's Call and Splendor of Tranquil Waters come next. No playtested ranking has been imported for Nilou, so this is arithmetic over the kit data rather than a damage measurement.

Run Heart of Depth on Nilou, with Nymph's Dream and Vourukasha's Glow behind it. Main stats are HP% sands, HP% goblet, HP% circlet. Roll substats in the order Energy Recharge > HP% > CRIT Rate > CRIT DMG.

Talent priority is Elemental Burst > Elemental Skill > Normal Attack. The Elemental Burst costs 70 energy, which is what an Energy Recharge target has to clear.

The strongest team is Nilou, Columbina, Lauma and Nahida, built around Nilou — Bloom · Bountiful Cores.

Nilou Dance of Haftkarsvar — elemental skill icon | Genshin Impact
Skill

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."

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.
