Looking for the best Genshin Impact Sayu build? This napping ninja drops alongside Yoimiya's Banner of Golden Flames, and she looks like a lot of fun in a fight. She's not just Genshin's first pint-sized claymore user, but she can also turn into a ball and roll around the battlefield, running down poor enemies.

Sayu may have been somewhat overshadowed by Ayaka (opens in new tab) and Yoimiya (opens in new tab), but some of her abilities are still pretty powerful. Mujina Flurry, for example, offers Bennett-esque healing, but when it hits that 70% cap, it starts to cause Anemo damage to nearby opponents instead, which is pretty useful.

With less than a month left until Genshin Impact 2.1 (opens in new tab) and a whole crop of strong new characters including Aloy (opens in new tab), and possibly Baal (opens in new tab), it could be easy to lose excitement for a four-star like Sayu. But personally, I'm just happy crushing enemies under a ball of Anemo death. 

Here's our best Genshin Impact Sayu build, along with details on how to get her, and what Ascension materials you're going to need.

The best Genshin Impact Sayu build

The best Sayu build takes advantage of her amazing support abilities, increasing Anemo damage, while also boosting energy recharge so she can use them more.

Support build

  • Weapon: Katsuragikiri Nagamasa

The new craftable four-star claymore, Katsuragikiri Nagamasa, is a very good fit for Sayu. It boosts energy recharge by 10%, as well as elemental skill damage by 6%. Every time an elemental skill hits and opponent, your character loses three energy, but regenerates three every two seconds for the next six seconds. This can happen once every ten seconds.

It sounds complex, but considering Sayu's Muji-Muji Daruma can continously attack opponents, it offers a damage boost, as well as some great energy regeneration, so she can use her burst more often. You can get the diagram for this claymore by completing the Tartara Tales quests on Tatarasuna, and entering The Arsenal.

  • Artifact: Viridescent Venerer

This artifact set is made for Anemo characters, with a two-piece set granting an Anemo damage bonus of 15%. Four pieces also increases Swirl damage by 60%, while decreasing enemies' elemental resistance to the element infused in the Swirl by 40% for ten seconds.

This set really boosts the strength of Sayu's Swirl reaction, and allows her to better support any character on her team, by decreasing enemy resistance to their particular element. 

How to unlock

How to get Sayu in Genshin Impact

Sayu arrived in Genshin Impact as part of the Banner of Golden Flames on August 10. She'll be featured alongside boosted rates for new five-star character, Yoimiya, but also Cryo archer Diona, and Pyro claymore-user Xinyan. 


Sayu's abilities

Here are Sayu's abilities, passives, and constellations:

Elemental Skill
Yoohoo Art - Fuuin DashIf you press, Sayu curls up into a Fuufuu Windwheel and drives a short distance into opponents, dealing AoE Anemo damage. When the duration ends she unleashes a Fuufuu Whirlwind Kick that also deals AoE Anemo damage. If you hold, Sayu rolls continuously and can be directed, gaining resistance to interruption, and triggering elemental absorption for any elements she comes into contact with. Pressing the skill again ends this state, and Sayu deals a more powerful version of the Fuufuu Whirlwind Kick. The skill has a maximum duration of ten seconds, and its cooldown increases based on how long Sayu is in Windwheel form.
Swipe to scroll horizontally
Elemental Burst
Yoohoo Art - Mujina FlurrySayu summons a pair of helping hands that deal Anemo damage to nearby opponents and heal nearby party members. The amount healed scales on Sayu's attack. The skill then summons a Muji-Muji Daruma that takes actions at specific intervals depending on the situation. If the HP of nearby characters is above 70% it attacks nearby opponents dealing Anemo damage. If active characters have 70% HP or less, it heals the character with the lowest percent HP. If there are no enemies present, it heals active characters even if they have 70% HP or more.

Multi-Task no JutsuThe Muji-Muji Daruma created by Mujina Flurry ignores HP limits and can both attack and heal at the same time.

Ascension materials

Sayu Ascension materials


Sayu's character ascension materials are the usual Vayuda Turquoise from the Anemo Hypostasis, and Maguu Kishin from the Maguu Kenki boss. You'll also need two world materials:

  • Crystal Marrow 
  • Whopperflower Nectar

As Crystal Marrow is literally the bone marrow of the Tatarigami serpent you can find it attached to the giant snake skeleton scattered across Yashiori island. Whopperflower-series items are dropped by Whopperflowers of different world levels. They appear all over, but I find the best way to locate one is to go into the enemies section of my Adventurer's Handbook and select navigate.

Genshin Impact Ayaka build: Frostflake Heron
Genshin Impact Ganyu build: Secretary of Yuehai Pavillion

Here are Sayu's talent ascension materials:

As mentioned, Whopperflower Nectar and its other types are dropped by Whopperflowers of different world levels. Teachings of Light are a reward from the Violet Court domain on Wednesdays, Saturdays, and Sundays. 

The Gilded Scale is earned through the level 70+ Azhdaha boss challenge in the trounce domain, and Crowns of Insight come from seasonal events, and upgrading either the Frostbearing Tree of Dragonspine, or the Sacred Sakura of Inazuma.
