Talents and Constellations

For skill and talents, we are covering Sayu combat talents, passive talents, and all 6 constellations.

Combat Talents

Talent	Description
Shiyuumatsu-Ban Ninja Blade (Normal Attack)	– Normal Attack: Perform up to 4 consecutive strikes. – Charged Attack: Drains Stamina over time to perform continuous spinning attacks against all nearby opponents. At the end of the sequence, perform a more powerful slash. – Plunging Attack: Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.
Yoohoo Art: Fuuin Dash (Elemental Skill)	The special technique of the Yoohoo Ninja Arts! Curl up into a rolling Fufu Windwheel and smash into opponents at high speed, dealing Anemo DMG. When the duration ends, unleashes a Fufu Whirlwind Kick, dealing AoE Anemo DMG. Press Enter the Fufu Windwheel state, roll forward a short distance before using the Fufu Whirlwind Kick. Hold Roll about continuously in the Fufu Windwheel state, increasing Sayu’s resistance to interruption while within that state. During this time, Sayu can control the direction of her roll, and can use the skill again to end her Windwheel state early and unleash a stronger version of the Fufu Whirlwind Kick. The Hold version of this skill can trigger Elemental Absorption. This skill has a maximum duration of 10s and enters CD once its effects end. The longer Sayu remains in her Windwheel state, the longer the CD. Elemental Absorption If Sayu comes into contact with Hydro, Pyro, Cryo, or Electro while in her Windwheel state, she will deal additional elemental DMG of that type. Elemental Absorption may only occur once per use of this skill. Sayu can pull this skill off with her eyes closed. This technique was originally created for escaping, but now that she’s got a Vision, might as well make her foes eat dirt while she’s at it.
Yoohoo Art: Mujina Flurry (Elemental Burst)	The other super special technique of the Yoohoo Ninja Arts! It summons a pair of helping hands for Sayu. Deals Anemo DMG to nearby opponents and heals all nearby party members. The amount of HP restored is based on Sayu’s ATK. This skill then summons a Muji-Muji Daruma. Muji-Muji Daruma At specific intervals, the Daruma will take one of several actions based on the situation around it: – If the HP of nearby characters is above 70%, it will attack a nearby opponent, dealing Anemo DMG. – If there are characters with 70% or less HP nearby, it will heal the character with the lowest percentage HP left. If there are no opponents nearby and nearby characters are above 70% HP, it will heal characters. People who don’t know the first thing about ninjutsu love to watch Sayu show off this skill, and some have tried to learn it from her. But Sayu just wants to sleep and not be disturbed.
