How to ascend Nilou from Genshin Impact

Nilou is a dancer at the Zubayr Theater located in the Grand Bazaar in Sumeru City; she wields a Sword and has Hydro Vision; given her profession, most of her moves are dance moves.

Requirements for ascension

• Tighnari if you have him for an easier time finding materials.
• Access to the Steeple of Ignorance domain for Talent Level-up materials (Wed/Sat/Sun)
• Adventure Rank 40 or have finished Raiden Shogun's Story Quest Imperatrix Umbrosa Chapter: Act II - Transient Dreams for the Talent Level-up materials after Level 6 (weekly)
• 46 Perpetual Calibers
• 168 Padisarah
• 18 Fungal Spores, 30 Luminescent Pollen, and 36 Crystalline Cyst Dust (for ascension)
• 6 Fungal Spores, 22 Luminescent Pollen, 31 Crystalline Cyst Dust (per talent)
• 18 "Tears of the Calamitous God"

Where to get ascension Materials

You can find Padisarah all over the Sumeru Forest, especially in Vanarana, so you'll have to start the Aranara Quest at least. There are 68 on the map; to get all 168, you'll have to visit other players or wait a few 48-hour resets. Having Tighnari on your team will mark them on your minimap.

Padisarah Locations

Fungi drop Fungal Spores, Luminescent Pollen, and Crystalline Cyst Dust; DO NOT use Pyro nor Electro on them, or the type of materials change.

You get Perpetual Calibers from the Aeonblight Drake boss fight located southwest of The Chasm.

How to get to the Steeple of Ignorance domain

The Steeple of Ignorance domain is northwest of Sumeru City; nothing blocks the entrance other than the Adventure Rank 27 requirement. Nilou's Talent Materials refer to Praxis; these appear on Wednesdays, Saturdays, and Sundays.

How to Level up Talents over Lv.6

The "Tears of the Calamitous God" to level up Nilou's talents beyond level 6 are possible rewards you can get for defeating the Raiden Shogun inside the End of the Oneiric Euthymia domain; you unlock this domain after completing the Raiden Shogun's Second Story Quest Imperatrix Umbrosa Chapter: Act II - Transient Dreams; alternatively, you can challenge her through your Adventurer Handbook after you hit Adventure Rank 40.
