Genshin Impact Kokomi has just arrived in Teyvat as the latest playable character. She's the last of the new heroes coming with the 2.1 update and follows in the footsteps of the Raiden Shogun (Baal) and Kujou Sara

If you've been keeping up with the Archon quests, you'll know that Sangonomiya Kokomi is the leader of the resistance, based on Watatsumi Island in the Inazuma region. So if you're looking for more details on this five-star Hydro character, here are Genshin Impact Kokomi's builds, abilities, and constellations.


The best Genshin Impact Kokomi build 

As Kokomi is primarily a support character, I've gone with a healing build. That said, her Elemental Burst has the potential to deal decent damage, though you'll be fighting against a negative crit-rate, thanks to her Flawless Strategy passive. 


Weapon: Prototype Amber

This four-star catalyst is a solid choice for Kokomi. It gives her a sizable HP boost which in turn, increases her healing—and damage inside her Elemental Burst window. This catalyst also regenerates Energy whenever Elemental Burst is used, which is incredibly useful for lowering the downtime between abilities.

Artifact: Maiden Beloved (2-piece), Tenacity of the Millelith (2-piece)

Having the first bonuses of these two artifact sets should set Kokomi up as a powerful healer. Maiden's two-piece set bonus increases healing by 15%, which means outgoing heals will be more powerful. The Millelith two-piece set bonus increases Kokomi's max HP, which is what her healing scales with, so you're further increasing her healing potential.

If you want to lean more towards damage, replacing Millelith with Heart of Depth could be a viable alternative.

Kokomi's Ascension materials 


You'll need specific Ascension materials if you want to level up Sangonomiya Kokomi. The Dew of Repudiation and Varunada Lazurite are both dropped by Hydro Hypostases, while the latter can also be looted from Oceanids. Besides those, you'll also need the following items:

  • Sango Pearl
  • Spectral Husk/Heart/Nucleus

Sango Pearl can be found around Watatsumi Island, so if you've spent much time exploring the area, you've likely collected some already. The Spectral items are dropped by Specters, a new enemy type that is exclusive to both the Watatsumi and Seirai islands.


These are the items you'll need to ascend Kokomi's talents:

  • Teachings of Transience
  • Spectral Husk/Heart/Nucleus
  • Hellfire Butterfly
  • Crown of Insight

The Teachings of Transience—and its variations—can be obtained from the Violet Court domain on Mondays, Thursdays, and Sundays while, as mentioned above, the Spectral items are dropped by Specters found on Watatsumi and Seirai island. The Crown of Insight is a reward for upgrading the Frostbearing Tree in Dragonspine or the Sacred Sakura in Inazuma. You can also get it from various seasonal activities, like Midsummer Island Adventure or Thunder Sojourn. 

Potentially the most difficult Ascension material to obtain is the Hellfire Butterfly, which is dropped by the La Signora weekly boss at level 70 and above.

Sarah's earliest gaming memories involve playing Jet Set Willy on the ZX Spectrum at a friend's house. These days, and when not writing guides, most of her spare time goes into MMOs—though she's quite partial to JRPGs too. She has spent much of the last decade playing the likes of Star Wars: The Old Republic, TERA, Final Fantasy 14, and World of Warcraft. Sarah has been writing about games for several years and, before joining PC Gamer, freelanced for the likes of TechRadar, GamingBible, and Rock Paper Shotgun. One of her fondest hopes is to one day play through the ending of Final Fantasy X without breaking down into a sobbing heap. She probably has more wolves in Valheim than you.
