Ayato Reaction Soup Raiden
This team is more of a Raiden team than an Ayato one, with the majority of buffs being active during Raiden's Burst. While it has similar DPR to the Fischl variant, both Raiden and Ayato desiring field time means that the rotation is extended, leading to overall less DPS. Furthermore, this team may struggle to Swirl both Hydro and Electro, oftentimes only Swirling Electro, especially with Kazuha's second Skill cast.
