Genshin Impact Nilou Build & Teams: 5-Star Hydro Polearm Bloom Enabler
Quick Answer
- Nilou is a 5-star Hydro Polearm (Sumeru dancer), a Bloom enabler/support who deals almost no personal damage.
- Core passive "Court of Dancing Petals": with a Hydro+Dendro-only party, normal Dendro Cores become Bountiful Cores — fast-bursting, wide-radius, and CRIT-immune.
- Artifacts: 2pc Tenacity of the Millelith + 2pc Vourukasha's Glow (best mixed set); main stats HP% Sands / HP% Goblet / HP% Circlet ("triple HP").
- Weapon: signature Key of Khaj-Nisut (HP converted to team-wide EM); F2P Iron Sting or Xiphos' Moonlight.
- Talent priority: Elemental Skill > Elemental Burst >> Normal Attack (skip NA).
- HP stacks: aim for 74,444 HP to cap her A1 (every 1,000 HP above 30,000 adds 9% Bountiful Core DMG, capped at 400%).
- Best team: Nilou + Nahida + Kokomi + Collei (pure Hydro-Dendro Bloom); C0 is already complete.
Role Mechanics
Nilou doesn't deal personal damage — she turns the whole team into a Bloom engine:
- Elemental Skill "Dance of Haftkarsvar": Tap (Sword Dance) applies Hydro, Hold (Whirling Steps) deploys a Hydro ring. Three E casts set up max Hydro application — the core of Bloom triggering.
- Core passive "Court of Dancing Petals": With a Hydro+Dendro-only party, normal Dendro Cores upgrade to Bountiful Cores — they burst faster, hit a wider radius, ignore CRIT, and cannot trigger Hyperbloom/Burgeon.
- A1 passive "Dreamy Dance of Aeons": Every 1,000 Max HP above 30,000 adds 9% Bountiful Core DMG, capped at 400% — so everything revolves around HP.
- Elemental Burst "Dance of Abzendegi": AoE Hydro DMG scaling off HP with sustained application; only 60 energy, easy to rotate.
Artifacts
| Set | 2pc | 4pc |
| 2pc Tenacity + 2pc Vourukasha | HP +20% + HP +20% | +40% HP total — easiest to build (recommended) |
| Vourukasha's Glow 4pc | HP +20% | HP +10% and extra HP after Bloom — high-investment best |
| Deepwood Memories 4pc (for Hydro teammate) | Dendro RES -15% | Bloom DMG +80% — give to Kokomi/Barbara |
Main Stats & Substats
| Slot | Main stat |
| Sands | HP% |
| Goblet | HP% |
| Circlet | HP% |
Substat priority: HP% > Elemental Mastery > Energy Recharge > flat HP. Target 74,444 HP to cap her A1 (9% per 1,000 HP over 30,000, cap 400%); stay above 50,000 at minimum. Nilou ignores CRIT entirely — CRIT substats are wasted.
Weapons
| Weapon | Rarity | Note |
| Key of Khaj-Nisut | 5★ | Massive HP% + converts HP to team EM — best-in-slot |
| The Dockhand's Assistant | 4★ | HP% stat-stick, high value |
| Xiphos' Moonlight | 4★ | EM-to-team-ER, eases rotation |
| Iron Sting | 4★ (craftable) | EM bonus, F2P friendly |
| Traveler's Handy Sword | 3★ | HP% stat-stick, early game |
Teams
Pure Bloom (standard)
Nilou + Nahida (Dendro) + Kokomi/Barbara (Hydro healer) + Collei/Dendro MC (2nd Dendro)
- Double Hydro + double Dendro; the healer drives on-field and triggers Bountiful Cores while Nilou's E sets up the Hydro ring and Nahida applies Dendro off-field.
- Hydro+Dendro only — any Pyro/Electro/Cryo/Anemo disables the passive.
Top-tier Bloom
Nilou + Nahida + Yelan + Baizhu
- Yelan's off-field DMG + Baizhu's sustain/shield — overkill AoE.
F2P / free-to-play
Nilou + Dendro MC + Collei + Barbara
- Fully free; at 60,000 HP Nilou clears Abyss groups easily.
Constellations
- C0: Complete kit — playable at C0.
- C2: 35% Hydro/Dendro RES shred — biggest spike, worth pulling to C2.
- C6: Opens a direct-damage playstyle (NA/Skill become Hydro) — very costly.

FAQ
Must Nilou be Hydro+Dendro only?
Yes. Court of Dancing Petals requires a party of only Hydro and Dendro characters; any Pyro/Electro/Cryo/Anemo teammate disables the passive and reverts cores to normal.
Best Nilou weapon?
Key of Khaj-Nisut is best-in-slot (HP converted to team EM). Without it, Iron Sting (craftable, EM) or Xiphos' Moonlight work well.
Does Nilou need CRIT?
No. Bountiful Cores ignore CRIT; stack HP% and a little EM. CRIT substats are wasted.
How much HP for Nilou?
Target 74,444 to max her A1 passive (9% per 1,000 HP over 30,000, cap 400%); stay above 50,000 at minimum.
Which constellations matter?
C0 is complete; C2 adds Hydro/Dendro RES shred (big spike); C6 opens a direct-damage playstyle but is costly.
