Genshin Impact Nilou Build Guide, Weapons & Team Comps

Nilou is a 5-star Hydro Sword user who excels as a unique Bloom-focused support and reaction damage enabler in Genshin Impact. Her gameplay revolves around using her Elemental Skill, Dance of Haftkarsvar, to activate her dance steps and enable Bountiful Cores when the party is made only of Hydro and Dendro characters. These special cores explode much faster and have a larger AoE than regular Dendro Cores, making Nilou especially powerful in AoE combat. Since her kit scales heavily with Max HP, building as much HP as possible allows her passive Dreamy Dance of Aeons to greatly increase Bountiful Core DMG. While her Elemental Burst, Dance of Abzendegi: Distant Dreams, Listening Spring, provides AoE Hydro DMG, her main strength comes from enabling strong Bloom reaction damage through consistent Hydro application and team-wide synergy. In this Nilou build guide, we’ll cover her best builds, recommended weapons, artifacts, and team compositions to maximize her full potential.

• Nilou Gameplay

Nilou’s gameplay revolves around enabling powerful Bloom reactions through her Elemental Skill, Dance of Haftkarsvar. Instead of focusing on traditional CRIT damage, Nilou performs best in teams made only of Hydro and Dendro characters, where her passive talent allows Bloom reactions to create Bountiful Cores instead of regular Dendro Cores.

Her Elemental Skill puts Nilou into the Pirouette state, allowing her to perform different dance steps. For most Bloom teams, using Whirling Steps is the preferred option, as it creates a Tranquility Aura that follows the active character and applies Hydro to nearby enemies. This helps maintain Hydro application while Dendro teammates continue triggering Bloom reactions.

Nilou’s main strength comes from her passive talent, Court of Dancing Petals. When the team meets the Hydro + Dendro only condition, completing her third dance step grants Golden Chalice’s Bounty, causing Bloom reactions to generate Bountiful Cores. These cores explode much faster and have a larger AoE, making Nilou extremely strong in multi-target combat.

Her Elemental Burst, Dance of Abzendegi: Distant Dreams, Listening Spring, deals AoE Hydro DMG based on Nilou’s Max HP and applies an additional Hydro hit after a short delay. While useful for extra damage and Hydro application, her Burst is not the center of her kit. Overall, Nilou performs best by stacking Max HP, activating her Skill properly, and supporting teams built around constant Hydro and Dendro application to maximize Bountiful Core damage.

Nilou Talent Priority

Nilou’s talent priority focuses mainly on her Elemental Skill, as Dance of Haftkarsvar is the core of her gameplay and the main way she enables Bountiful Cores in Hydro and Dendro teams. While Nilou’s Bloom damage depends more on her Max HP and passive talents than talent multipliers, leveling her Skill still improves her personal Hydro DMG and overall performance. Her Elemental Burst, Dance of Abzendegi: Distant Dreams, Listening Spring, comes next because it deals AoE Hydro DMG based on Nilou’s Max HP and can provide extra damage during rotations. However, it is less important than her Skill in Bloom-focused teams. Her Normal Attack has the lowest priority, since Nilou rarely relies on regular Normal Attack damage.

Elemental Skill – Dance of Haftkarsvar

Nilou’s Elemental Skill is her highest priority and the core of her kit. It allows her to enter the Pirouette state, perform her dance steps, and activate the setup needed for Bountiful Cores in Hydro and Dendro teams. Since this is the main way Nilou enables her Bloom-focused playstyle, it should be leveled first in most Nilou builds, mainly to improve her personal Hydro DMG.

Elemental Burst – Dance of Abzendegi: Distant Dreams, Listening Spring

Nilou’s Elemental Burst is her second priority. It deals AoE Hydro DMG based on her Max HP and applies an additional Hydro hit after a short delay. However, because Nilou’s main damage comes from Bountiful Cores and Bloom reactions, her Burst is less important than her Elemental Skill and should be leveled after it.

Normal Attack – Dance of Samser

Nilou’s Normal Attack is the lowest priority. Although she can use sword attacks, her standard Normal Attacks are rarely important in Bloom teams. Her enhanced dance attacks are considered Elemental Skill DMG, so this talent can stay at a low level unless you want to play Nilou more on-field.

Nilou Best Weapons

To maximize Nilou’s performance, prioritize HP%, Flat HP, Elemental Mastery, and enough Energy Recharge to keep her rotations smooth. Since most of her value comes from enabling and strengthening Bountiful Core DMG, weapons that increase Max HP are the most valuable. If HP weapons are not available, Elemental Mastery swords are strong alternatives for improving Bloom reaction damage, while Energy Recharge weapons can help her use her Elemental Burst more comfortably.

Nilou Best Artifacts & Stats

To maximize Nilou’s performance as a Bloom-focused support, artifact choices should prioritize HP%, Flat HP, Elemental Mastery, and enough Energy Recharge for smoother rotations. Since most of her value comes from enabling Bountiful Cores and increasing their damage through her Max HP, the best artifact sets are those that increase HP% first. CRIT Rate, CRIT DMG, and ATK% are generally not important in her standard Bloom build.

Nilou Best Team Compositions

Nilou performs best in teams built around Bloom reactions, Bountiful Cores, and strong Hydro + Dendro synergy. She is mainly played as a Bloom Support / Bloom DPS, using her Elemental Skill to activate Golden Chalice’s Bounty and turn regular Bloom reactions into powerful Bountiful Cores. Since her passive requires the party to include only Hydro and Dendro characters, her best teams focus on consistent Hydro application, strong Dendro application, and enough survivability to handle Bloom self-damage.

Nilou Constellations

Nilou is already fully functional at C0 as a Bloom Support / Bloom DPS, with her main value coming from enabling Bountiful Cores in Hydro and Dendro teams. Her constellations mainly improve her Hydro application, increase team damage through resistance reduction, improve Energy consistency, and boost her personal Hydro damage. Among them, C2 stands out as her best premium stopping point because it greatly improves Bloom team damage, while C6 is her strongest late-game upgrade for players who want to increase Nilou’s personal damage.

Conclusion

This comprehensive guide highlights Nilou’s role as a unique Hydro Bloom Support / Bloom DPS in Genshin Impact, offering powerful reaction damage through Bountiful Cores, reliable Hydro application, and excellent synergy with Hydro and Dendro teams. By activating Golden Chalice’s Bounty through her Elemental Skill, Dance of Haftkarsvar, Nilou can transform regular Bloom reactions into fast-exploding cores with larger AoE, making her especially strong in multi-target combat.

While Nilou already performs very well at C0, her constellations mainly improve her Hydro application, team damage, Energy consistency, and personal Hydro damage. C1 improves her Skill utility, C2 is her best premium upgrade thanks to its Hydro RES and Dendro RES reduction, while C6 serves as her strongest late-game investment for players who want to increase Nilou’s personal damage through CRIT Rate and CRIT DMG scaling based on Max HP.
