Sayu is one of the most fun characters to play in Genshin Impact. As a four-star Claymore user, Sayu uses Anemo Damage to trigger Swirl while healing himself and his teammates. His position in a team can vary depending on his constitution, but players will still be able to find synergy in many compositions.
There are two main playstyles for players wishing to use Sayu effectively. This is due to his elemental skill scale and elemental burst, using both elemental mastery and attack to calculate damage. Depending on how players prefer to play Sayu, they can choose to max out their Elemental Mastery to boost his Whirlwind damage while also increasing his healing, or they can max out his Attack to boost his base Anemone Damage and heal his Burst.
Players will have to decide if they want to boost Sayu's Attack or Elemental Mastery, as they both offer similar functions. The attack will increase the damage of his normal and charged attacks, Anemo damage, and the amount of healing his Elemental Burst does. Elemental Mastery will increase Swirl's damage, passive skill healing, and make her more synergistic with other characters' elemental blasts. Elemental Mastery is better overall, but that doesn't invalidate attack builds.
- Yoohoo Art: Fuuin Dash – This is easily one of the most fun elemental skills in the game. Sayu can either do a quick kick if players choose to press the skill, or they can move continuously in a bullet like Sonic The Hedgehog if they hold. The cooldown for pressing is only six seconds, and the cooldown for holding the skill increases based on how long Sayu rolls. She can roll for up to 10 seconds and gain a maximum cooldown of 11 seconds. In this state, elemental absorption is possible, spreading an element while constantly whirling.
- Yoohoo Art: Mujina Flurry – Sayu's elemental burst deals damage immediately when he comes out and heals nearby party members. After the initial hit, it will heal characters below 70% HP, but if everyone is above that value, it will start attacking and dealing Anemo damage. Unlocking his first Constellation will remove the 70% cap and allow Muji-Muji Daruma to attack and heal regardless of character health. Despite this good scaling with Offense, Elemental Mastery is still the preferred stat to prioritize.

- Someone More Capable – This passive is another reason Elemental Mastery covers everything on Sayu. With it, whenever Sayu triggers a whirlwind reaction on the field, she heals all characters and allies for 300 HP plus an additional 1,2 HP for each Elemental Mastery point she has. Sayu, at level 90, gains 96 Elemental Mastery. With three Artifacts with Elemental Mastery as their primary stat, this can reach 655,5 not counting her weapon's additional Elemental Mastery, or Flower and Feather's sub-stats. That's 786,6 plus base 300 for a total of 1086,6 HP each time Swirl is triggered.
- No work today! – An additional way to heal allies, this passive increases the healing of Sayu's Elemental Burst. To do this, other characters heal for 20% of the damage healed, regardless of which character the Daruma is healing. It also increases the AoE of its attacks.
The choice of what Claymore to use for Sayu can vary as it heavily depends on how much energy she recharges and the energy saving of the team she is on.
- Wolf's Gravestone – A five-star weapon with 608 attack and a 49,6 percent attack substat, this weapon is easily the best weapon for Sayu. It's passive increases attack by an additional 40 percent at refinement five while buffing all party members' attack by 80 percent for 12 seconds when hitting enemies below 30 percent HP. It can happen every 30 seconds and is still one of the best buffs for many characters.
- Favonius Greatsword – As Sayu's energy cost for his elemental burst is quite high, running weapons that give him an energy recharge can be important to using his elemental burst cooldown. Favonius Greatsword is a four-star weapon that has an attack of 454 at level 90 with an energy recharge of 61,3%. It also has the ability to recover even more energy when it lands critical hits, as it will cause elemental particles to come out. If the crit rate is high compared to its secondary stats, this weapon is excellent to use to increase the energy saving of the whole team.
- Sacrificial Greatsword – This four-star weapon has an attack of 565 at level 90 and an energy recharge of 30,6%. It has a higher attack than the Greatsword Favonius but much less energy recharge, making it a good balance between players who don't want to sacrifice a lot of their damage from Anemo and normal attacks. His passive is the real reason to use him as he has a chance to reset Sayu's elemental skill whenever she deals damage to him. At refinement five, this chance is 80% and almost guaranteed to reset the cooldown with how much she damages enemies and triggers Swirl.
- Rainslasher/Bloodstained Greatsword – These are the only two Claymores that have Elemental Mastery as a sub-stat. They are very situational in their effects and the three-star Bloodstain Greatsword actually gives more Elemental Mastery at 187 compared to the Rainslasher's 165.
Whether prioritizing offense or elemental mastery, the Viridescent Venerer set is the best Sayu can use. It increases whirlwind damage by 60% while reducing elemental resistance to the infused element in whirlwind by 40% for 10 seconds. Achieving Elemental Mastery as the primary stat for these Artifacts may take some time, but the payoff is well worth it.
Noblesse Oblige also works as a support option, giving a 20% attack buff for 10 seconds to the party after Sayu uses his elemental burst. It's also much easier to get Noblesse Oblige Artifacts in Elemental Mastery, as players can use three bad Artifacts to exchange them for a random Noblesse Oblige Artifact in the crafting menu.

Best team for Sayu
Because Anemo's characters are so diverse, Sayu works in any team composition except one that relies heavily on Crystalize. Its ability to continuously stream elements, trigger whirlwinds, and stay mobile makes characters with elemental bursts that follow you very useful. Xiangling, Xinqiu, and Kaeya, for example, all have elemental shards that Sayu can stay in his bullet form to deal a high amount of damage.
Sayu teams that use elemental reactions are also very good because she can diffuse an element while another character creates reactions with her own attacks.
- Melt – Kaeya, Xiangling, Rosaria/Diluc
- Spray – Hu Tao, Xingqiu, Xiangling/Thoma/Amber
- Surcharge – Klee/Xiangling, Beidou/Lisa, Fischl
- Electrocharged – Xinqiu/Barbara, Fischl, Beidou/Lisa/Raiden
- Gel – Chongyun, Xinqiu, Rosaria/Shenhe
- Physics/Superconduct – Beidou/Raiden, Eula/Razor, Fischl/Rosaria/Kaeya
