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, Nahida, Dendro Traveler and Sangonomiya Kokomi, built around Nilou: Dendro · Bloom.

Nilou FAQ

3 questions

What is the best weapon for Nilou?

Key of Khaj-Nisut is the closest fit on the data: it is a 5-star sword with HP as its ascension stat, and its passive acts on HP. Serenity's Call is the best 4-star alternative.

Which artifact set should Nilou use?

Heart of Depth. Its 2-piece bonus is: Hydro DMG Bonus +15% Its 4-piece bonus is: After using Elemental Skill, increases Normal Attack and Charged Attack DMG by 30% for 15s.
