Say'ri

Weapon: Amatsu

Assist: Reposition / Flexible

Special: Noontime / Sol

Passive A: Kestrel Stance / Bonus Doubler / Darting Breath

Passive B: Close Call

Passive C: Pulse Smoke / Spd Smoke / Def Smoke / Flexible

Sacred Seal: Swift Stance / Darting Stance / Fierce Stance 

• This is a defensively oriented setup centered around Say’ri’s ability to tank hits through raw Speed-stacking. A +SPD IV thus makes for her ideal choice of Asset here, as maintaining high levels of Speed is crucial to her success. 
• Close Call is the centerpiece of this build as it allows Say’ri to turn her Speed into tanking power, reducing the damage she takes based on how much faster she is than his opponent. Combined with Amatsu, Say’ri can function confidently as a counter to a wide breadth of foes. 
• Thanks to Amatsu’s built-in Distant Counter effect, Say’ri has a rather flexible A slot. Her native Kestrel Stance is incredibly synergistic with the rest of this build, though Bonus Doubler (to heighten her raw stats as much as possible) and Darting Breath (to quickly activate healing Specials without relying on support) are both good options to consider.
• Amatsu also provides a useful Slaying effect which allows Say'ri to constantly activate healing Specials for improved sustain. Noontime is the natural choice here as its low cooldown lets Say’ri use it on every counterattack, but Sol may be considered if she is provided with accelerated cooldown support such as from Brave Lucina. 
• Smoke skills pair quite well with this build’s defensive playstyle. For Aether Raids, Pulse Smoke is ideal to shut down compositions centered on instant Special activations. Otherwise, Spd Smoke or Def Smoke are better for their generally greater applicability. Defensive seals that increase Say’ri’s key stats (i.e. Swift Stance and Darting Stance) complement this build. 

Weapon: Amatsu

Assist: Reposition / Flexible

Special: Iceberg / Moonbow 

Passive A: Kestrel Stance / Atk/Spd Solo 

Passive B: Null Follow-Up / Null C-Disrupt 

Passive C: Atk Smoke / Spd Smoke / Flexible

Sacred Seal: Swift Stance / Distant Def / Fierce Stance 

• This build applies a more generalist take to Say’ri’s intended playstyle. A +ATK IV is a great choice to round our her damage output, though a +SPD IV may be taken instead to further develop her ability to both perform and avoid follow-up Attacks. 
• Her native Kestrel Stance once again makes for an excellent choice for the strong boost it provides in the Enemy Phase, though Atk/Spd Solo may be considered should one wish for Say’ri to have some functionality in the Player Phase as well. 
• Null Follow-Up and Null C-Disrupt are strong candidates for Say’ri’s B slot here, as they both serve to extend the breadth of foes she can safely take on and assist her in taking on a generalist role. The choice between which to use will largely boil down to skill availability and personal preference. 
• Smoke skills are recommended to debilitate opposing foes and improve the quality of her subsequent match-ups, with Atk Smoke and Spd Smoke being her best options here to boost her survivability. Lastly, any defensive seals that boost her key stats remain ideal.
