Gaming applies pyro at the start of the chamber by doing Ep. He plunges 8 times per rotation. Emilie uses her skill on the first rotation then bursts every other one.
Chasca Fischl Ororon Sara. ~26s rot. 3[C] (Q). Sara and Chasca use their E twice. Chasca does a short combo and cancels her E early to reduce its cooldown. Sara buffs both Fischl and Chasca.
Yoimiya Chevreuse Fischl Lisa. ~27s Rot. (TF) Yoimiya Overload. Chevreuse passes particles to Lisa if possible. Hamayumi doesn't justify not using burst.
Raiden Furina Sara Xilonen. ~20s Rot. Raiden Taser. 2E Xilonen with particles passed into Sara, who also buffs herself. Xilonen Scrolls Electro reliably, Hydro less so.
Raiden Nahida Fischl Lanyan. ~18s Rot. Shielded Raiden Aggravate with Lanyan. Swirling Electro reliably is pretty easy even without Fischl C6. Fischl uses skill after Raiden burst if available.
Ayaka Furina Rosaria Xianyun. ~22s Rot. Ayaka Cryo Plunge. 6 Plunges(one phys), canceled with N1 to avoid the slow jumps from special dash. Xianyun does not refresh the Cryo VV; damage is frontloaded damage and Shatter may make it annoying anyway.
Arle Furina Yelan Baizhu. Yelan 2E 21s rot. No Arle Q, 3[N5D] N1 (4[N4D] is similar). Arle ATK/ATK/CRIT was slightly better due to high DMG% buffs. Baizhu 4OHC(Clam) > 4SoDP > 4NO but used 4SoDP here.
