Chevreuse

• Strong buffer with her potent Pyro and Electro RES Shred and ATK buffs for the entire party simply by triggering Overloaded and using her Skill. Moreover, her ATK buffs lasts for 30 long seconds.
• Chevreuse's buffs makes up for the lack of Anemo support from Viridescent Venerer in her dedicated teams. She can substitute the likes of Kazuha for those who want to insert him in other team comps. In addition, he's mostly comparable to C0 Kazuha, but her C6 can potentially surpass his buffs in an Overloaded team.
• On top of all the buffs, she can also heal the active character with her Elemental Skill.
• Can generate around 4 energy orbs, while only having 60 energy cost.
