I tried so many different teams for this even a noblesse hu tao with yaoyao to take the shield down so trust me when I say that C3 Iansan wasn't cutting it here, not enough overload to help with the armor, not consistent enough fav procs, buff not significant enough.
I favored breaking the boss twice over buffing Varesa more, and even that was a struggle without Chevreuse C4 for more ticks. The strat was basically a lot of fav procs, squeezing Varesa jumps as often as possible and and not missing a single second of a skill or ult from someone else.
