What is the best weapon for Sayu in Genshin Impact?

Sayu is a versatile 4-star Anemo character in Genshin Impact who excels in both support and sub-DPS roles. Her kit revolves around healing, crowd control, and elemental reactions, making her a valuable addition to many teams. To maximize Sayu's potential, it is essential to choose the right weapon, artifacts, and team composition while understanding her mechanics and playstyle.

Sayu's Elemental Skill, Yoohoo Art: Fuuin Dash, allows her to roll into a windwheel, dealing Anemo damage to enemies in her path. This skill can be held for continuous damage and mobility, making it useful for exploration and combat. Her Elemental Burst, Yoohoo Art: Mujina Flurry, summons a Muji-Muji Daruma that heals allies and deals Anemo damage to nearby enemies. Sayu's passive talents further enhance her utility, such as her ability to heal the party when triggering Swirl reactions.

When building Sayu, the choice of weapon depends on her role in the team. For a support-focused Sayu, weapons that provide Energy Recharge or Elemental Mastery are ideal. The best 4-star weapon for support Sayu is the Favonius Greatsword. This weapon increases Energy Recharge, allowing Sayu to use her Elemental Burst more frequently. Its passive effect generates elemental particles when landing critical hits, further boosting energy regeneration for the entire team. Another excellent option is the Sacrificial Greatsword, which has a chance to reset the cooldown of Sayu's Elemental Skill, enabling more frequent use of her crowd control and healing abilities.

For a sub-DPS Sayu, weapons that enhance her damage output are preferable. The Katsuragikiri Nagamasa is a strong choice, as it increases Energy Recharge and boosts Elemental Skill damage. The passive effect also regenerates energy after using an Elemental Skill, ensuring consistent uptime for her abilities. If you have access to 5-star weapons, the Wolf's Gravestone is an excellent option for increasing Sayu's attack power, making her a more effective damage dealer.

Artifact selection is crucial for optimizing Sayu's performance. For a support build, the Viridescent Venerer 4-piece set is highly recommended. This set increases Anemo damage and reduces enemy resistance to the element Swirled, amplifying the damage output of your team. Main stats to prioritize are Energy Recharge on the Sands, Elemental Mastery or Anemo Damage Bonus on the Goblet, and Healing Bonus or Elemental Mastery on the Circlet. Sub-stats should focus on Energy Recharge, Elemental Mastery, and Attack Percentage.

For a sub-DPS build, consider a 2-piece Viridescent Venerer and 2-piece Gladiator's Finale or Shimenawa's Reminiscence. This combination boosts Anemo damage and attack power, enhancing Sayu's damage potential. Main stats should prioritize Attack Percentage on the Sands, Anemo Damage Bonus on the Goblet, and Critical Rate or Critical Damage on the Circlet. Sub-stats should focus on Critical Rate, Critical Damage, and Attack Percentage.

Team composition plays a significant role in maximizing Sayu's effectiveness. Pairing her with characters who can trigger powerful elemental reactions is key. For example, combining Sayu with a Hydro character like Xingqiu or Kokomi can create Swirl reactions that spread Hydro, enabling further reactions like Vaporize or Electro-Charged. Including a Pyro character such as Bennett or Xiangling can enhance damage output through Overloaded or Vaporize reactions. An Electro character like Fischl or Raiden Shogun can also synergize well with Sayu, creating Electro-Charged or Overloaded reactions.

Common mistakes to avoid when building Sayu include neglecting her Energy Recharge needs, which can lead to infrequent use of her Elemental Burst. Additionally, focusing solely on attack power without considering Elemental Mastery can reduce the effectiveness of her Swirl reactions. It is also important to balance her healing and damage capabilities based on her role in the team.

Advanced techniques for Sayu include using her Elemental Skill to group enemies and trigger multiple Swirl reactions in quick succession. Timing her Elemental Burst to coincide with other characters' abilities can maximize damage output and healing. Additionally, leveraging her passive talent that heals the party when triggering Swirl reactions can provide consistent sustain during combat.

In summary, the best weapon for Sayu depends on her role in the team. For support, the Favonius Greatsword or Sacrificial Greatsword are excellent choices, while the Katsuragikiri Nagamasa or Wolf's Gravestone are ideal for sub-DPS. Pairing her with the right artifacts and team composition will further enhance her effectiveness, making her a valuable asset in both exploration and combat. By understanding her mechanics and optimizing her build, you can fully utilize Sayu's potential in Genshin Impact.
