Yaoyao focuses on healing and applying Dendro with her Skill and Burst. She can be used in a wide range of team archetypes, but do note her Dendro application from her Skill alone is generally insufficient for Bloom/Hyperbloom/Burgeon teams as a solo Dendro option.
The additional Yueguis summoned by the Burst are removed when Yaoyao leaves the field.
If using , you can perform Skill followed by two Normal Attacks in order to trigger the passive.
Regarding Weapon Choices:
Favonius Lance: This weapon is a good generalist option for Yaoyao, providing Energy Recharge with a useful passive.
Rightful Reward: This weapon performs worse if you are not planning to use Yaoyao's Burst.
Kitain Cross Spear: This weapon can be better than in teams where Yaoyao has a significant amount of Bloom ownership.
Regarding Artifact Choices:
In a Bloom team where Yaoyao has a significant amount of Bloom ownership, Elemental Mastery is preferred as a Main Stat on your Goblet and Circlet, Elemental Mastery can also be used on your Sands if an Energy Recharge Sands is not required. Additionally, Elemental Mastery substats become good.
Sets
Deepwood Memories (4): This set is the default option in teams where you care about reducing Dendro resistance and nobody else on the team is using it.
Tenacity of the Millelith (4): This set is a good option in teams where reducing Dendro resistance is not important, such as Yaoyao, Anemo, two Electro damage dealers (Aggravate).
Instructor (4): Similarly to , this set can be a good option in teams where reducing Dendro resistance is not important, or if someone else on the team is already using . Do note that Yaoyao has to trigger a reaction on-field to provide the 4pc bonus. Additionally, your stat potential on this set will be limited as it does not come in 5* rarity.
Ocean-Hued Clam (4): This set is a good option in teams where you on-field Yaoyao and a supportive set is not needed.
Flower of Paradise Lost (4): This option is specifically for Nilou Bloom teams where Yaoyao has a significant amount of Bloom ownership and is built with Elemental Mastery. Do note that (4) can still be better in these teams, assuming you on-field Yaoyao.
Gilded Dreams (4): This option is specifically for Nilou Bloom teams where Yaoyao has a significant amount of Bloom ownership and is built with Elemental Mastery. Do note that (4) can still be better in these teams, assuming you on-field Yaoyao.
+80 EM set (2): This option is specifically for Nilou Bloom teams where Yaoyao has a significant amount of Bloom ownership and is built with Elemental Mastery. Do note that (4) can still be better in these teams, assuming you on-field Yaoyao.
Substats
Energy Recharge: Prioritize until requirements are met.
CRIT Rate: Try to build some CRIT Rate through substats if using . CRIT Rate is not important on other weapons.
Regarding Talent Choices:
Skill: Prioritize her Skill if you do not spend time on-field with Yaoyao after using her Burst.
