Nilou is a 5-star Hydro sword user from Sumeru, introduced in Version 3.1. As a celebrated dancer of the Zubayr Theater, Nilou’s graceful elegance extends into combat through her unique Bountiful Core mechanic, which enhances Bloom reactions when paired with Dendro teammates.

The best Nilou build focuses on HP scaling and Elemental Mastery, allowing her to serve as a core enabler in Bloom teams with unmatched synergy.

Nilou can only reach her full potential in teams consisting exclusively of Hydro and Dendro characters, which activates her Golden Chalice Bounty passive.

When active, she converts Blooms into Bountiful Cores, which explode faster and deal greater AoE Dendro DMG — making her a top-tier reaction-focused character.

How to Play Nilou Effectively

Nilou’s gameplay centers on activating her Golden Chalice Bounty passive by creating a team with only Hydro and Dendro units. Once active, Bloom reactions triggered by her Skill or Hydro application produce Bountiful Cores, which explode faster and hit harder.

The best Nilou build stacks HP and Elemental Mastery to fuel massive Bloom damage while offering natural synergy with off-field Dendro supports.

Use Elemental Skill to enter the Dance state, weave in Normal Attacks, then swap to Dendro allies to trigger continuous Bloom explosions. Stay within Hydro-Dendro comps to unlock her full potential.

Is Nilou Worth Building?

Yes — Nilou is one of the best reaction enablers in Genshin Impact when used correctly. Her specialized build and team requirements are limiting, but in Dendro-Hydro teams, she becomes an irreplaceable source of massive AoE damage.
