Sayu, the Mujina Ninja of the Shuumatsuban

Rarity	(4-Star)
Element	Anemo
Weapon	Claymore
Best Role	Healer / VV Support / Driver
Stat Priority	ER > EM (Swirl) > ATK (Heal)
Tier	B (Niche Healer/Driver)

Sayu is the sleepiest ninja of the Shuumatsuban. She is a unique hybrid of healer and driver. Her Elemental Skill allows her to roll around the battlefield, spreading elements (Swirl) while dealing damage, making her surprisingly effective in teams that require constant elemental application.

Pros

Best overworld exploration skill (fast rolling).
Can heal and shred RES (VV) simultaneously.
Swirls multiple times during her roll (Driver potential).
Passive prevents startling Crystalflies.

Cons

Healing scales on ATK (squishy) or EM (C6), making builds split.
Energy hungry (80 cost burst).
Rolling can be interrupted by heavy attacks.
Outclassed by Jean (instant heal) and Kazuha (buffs).

Quick Guide (TL;DR)

If you don't have time for the math, here is the cheat sheet.

Best Artifact: 4pc Viridescent Venerer (Mandatory for Support).
Alt Artifact: 4pc Ocean-Hued Clam (Healer/Driver).
Best Weapon: Wolf's Gravestone (ATK Buff) or Beacon of the Reed Sea.
F2P Weapon: Katsuragikiri Nagamasa (Craftable - Solves Energy).
Support Weapon: Favonius Greatsword (Team Battery - BiS).
Main Stats: SANDS: ER% or EM | GOBLET: EM or ATK% | CIRCLET: Healing Bonus or EM.
Talent Priority: Elemental Burst > Elemental Skill > Normal Attack.
Top Team: Sayu + Xiangling + Kaeya + Rosaria (Sayunado).

Pro Tip: Roll to Win: In combat, use Hold E to roll. If you roll into an element (Pyro/Hydro/Electro/Cryo), you absorb it. You can then roll into enemies to apply that element + Anemo constantly, triggering endless Swirls.

Talent Breakdown & Mechanics

Elemental Skill: Yoohoo Art: Fuuin Dash

Fuufuu Windwheel: Sayu curls into a ball. Holding E lets you roll for up to 10s.
Elemental Absorption: If she touches Hydro/Pyro/Cryo/Electro while rolling, she absorbs it and deals additional damage of that type.
Swirl: While rolling, she triggers Swirl reactions periodically on enemies she touches.

Elemental Burst: Yoohoo Art: Mujina Flurry

Cost: 80 Energy | Cooldown: 20s
Muji-Muji Daruma: Summons a Daruma that heals nearby characters or attacks enemies.
Logic: If character HP > 70%, it attacks enemies (Anemo DMG). If HP < 70%, it heals the active character (Scales on ATK).

Passive: Someone More Capable

Healing on Swirl: Whenever Sayu triggers a Swirl, she heals all party members for 300 HP + 1.2 per point of her Elemental Mastery. This incentivizes building full EM for both damage and healing.

Talent Priority Order:

Elemental Burst (Level 9) - Main healing source.
Elemental Skill (Level 8) - Damage.
Normal Attack (Level 1) - Ignore.

Stat Requirements & ER Thresholds

Sayu needs high ER. C6 changes her build from ATK% to Full EM.

Constellation	Weapon	ER Requirement
C0 - C5	Favonius Greatsword	180% - 200%
C0 - C5	Katsuragikiri (Craftable)	160% - 180%
C6	Mailed Flower (EM)	200%+

Substat Priority (C0-C5):

Energy Recharge (Until requirement met)
ATK% (Healing scaling)
Elemental Mastery (Swirl dmg / Passive healing)

Substat Priority (C6):

Elemental Mastery (Heals & Damage scale off this now)
Energy Recharge
ATK%

Best Artifacts Comparison

Set Name	Role	Reasoning
4pc Viridescent Venerer (VV)	Mandatory	Shreds 40% Elemental RES. Sayu is an Anemo Support; she must wear this.
4pc Gilded Dreams	Dendro Teams	If someone else has VV (e.g. Kazuha), or in Dendro teams where VV is useless, this maximizes her EM for Swirl/Heal.
4pc Noblesse Oblige	Buffer	Decent for ATK buffing, but usually VV is better for team DPS.

Weapon Rankings

Weapon	Type	Performance	Notes
Favonius Greatsword	ER%	S+	High ER and batteries the team. Best for support. Requires Crit Rate.
Katsuragikiri Nagamasa	ER%	S (F2P)	Inazuma Craftable. Passive regenerates energy automatically. Solves her ER issues better than any other weapon for personal uptime.
Mailed Flower	EM	A (C6)	Highest EM Claymore (Event). Best for C6 healing/swirl scaling if you have enough ER artifacts.
Wolf's Gravestone	ATK%	A (Healer)	Massive ATK for C0-C5 healing scaling. Buffs team ATK.

Constellation Value

Sayu's C1 is essential for consistency. C6 transforms her build.

C1: Multi-Task no Jutsu - (Core) Removes the HP limit on her Burst. Now the Daruma attacks AND heals simultaneously. Essential for reliable swirl support.
C2: Egress Prep - (Damage) Increases Skill DMG by 3.3% for every 0.5s spent rolling. Makes "Roll to Win" playstyle viable.
C6: Sleep O'Clock - (Game Changer) The Daruma's healing and damage now scale with Sayu's Elemental Mastery. This allows you to build Full EM (for Swirls) without sacrificing Healing output.

Verdict: C1 is mandatory. C6 is optimal.

Top Team Compositions

1. Sayunado (Rolling National)

Driver: Sayu
Pyro: Xiangling
Cryo: Kaeya / Rosaria
Buffer: Bennett

Why it works: Xiangling's Pyronado and Kaeya's Glacial Waltz follow the active character. Sayu rolls into enemies, bringing these spinning bursts with her, triggering rapid Melt reactions while shredding RES with VV.

2. Aggravate Healer

Main DPS: Keqing / Yae Miko / Cyno
Dendro: Nahida / Baizhu
Electro: Fischl
Healer/VV: Sayu

Why it works: In teams that need an Anemo healer (because Kazuha doesn't heal), Sayu fits perfectly. She shreds Electro RES and heals the team.

Rotations & Combos

Standard Support Rotation:
Sayu Q > Sayu Tap E (Particles) > Swap to Main DPS

Driver Rotation (Rolling):
Sub-DPS Bursts (Xiangling/Kaeya) > Sayu Hold E (Roll around counter-clockwise) > Sayu E (Kick) at end.

Frequently Asked Questions

Jean vs. Sayu?
Jean has instant team healing (Burst) and better energy generation. Sayu is more fun (rolling), better for exploration, and better at driving off-field elements continuously. Jean is generally stronger in meta.

Does she need C6?
For healing build? No (ATK scaling works fine). For Swirl/Reaction build? Yes. C6 allows you to stack full EM without losing healing power.
