Best Artifacts

(2) Anemo DMG Bonus +15%
(4) Increases Swirl DMG by 60%. Decreases opponent's Elemental RES to the element infused in the Swirl by 40% for 10s.
The bread and butter artifact set for Anemo units, this set provides the ability to shred the enemy's elemental resistance while also buffing Sayu's Swirl damage output.
(2) Elemental Burst DMG +20%
(4) Using an Elemental Burst increases all party members' ATK by 20% for 12s. This effect cannot stack.
(2) Energy Recharge +20%
(4) Increases Elemental Burst DMG by 25% of Energy Recharge. A maximum of 75% bonus DMG can be obtained in this way.
(2) Healing Bonus +15%.
(4) When the character equipping this artifact set heals a character in the party, a Sea-Dyed Foam will appear for 3 seconds, accumulating the amount of HP recovered from healing (including overflow healing). At the end of the duration, the Sea-Dyed Foam will explode, dealing DMG to nearby opponents based on 90% of the accumulated healing. (This DMG is calculated similarly to Reactions such as Electro-Charged, and Superconduct, but it is not affected by Elemental Mastery, Character Levels, or Reaction DMG Bonuses). Only one Sea-Dyed Foam can be produced every 3.5 seconds. Each Sea-Dyed Foam can accumulate up to 30,000 HP (including overflow healing). There can be no more than one Sea-Dyed Foam active at any given time. This effect can still be triggered even when the character who is using this artifact set is not on the field.
(2) Energy Recharge +20%
(4) Increases Elemental Burst DMG by 25% of Energy Recharge. A maximum of 75% bonus DMG can be obtained in this way.
(2) Healing Bonus +15%
(4) When the equipping character heals a party member, the Yearning effect will be created for 6s, which records the total amount of healing provided (including overflow healing). When the duration expires, the Yearning effect will be transformed into the "Waves of Days Past" effect: When your active party member hits an opponent with a Normal Attack, Charged Attack, Plunging Attack, Elemental Skill, or Elemental Burst, the DMG dealt will be increased by 8% of the total healing amount recorded by the Yearning effect. The "Waves of Days Past" effect is removed after it has taken effect 5 times or after 10s. A single instance of the Yearning effect can record up to 15,000 healing, and only a single instance can exist at once, but it can record the healing from multiple equipping characters. Equipping characters on standby can still trigger this effect.

This artifact set trades Sayu's utility in favor of stronger healing and some extra damage. It is generally not recommended to farm this set for Sayu specifically.

**Crit Rate only for Favonius Greatsword. Sayu does more damage with EM builds and heals more with ATK hybrid builds, Healing Bonus circlet's can be used for better heals while maintaining respectable damage. Note that Sayu wants a large amount of Energy Recharge when used as the only Anemo slot on the team.
