edit: added builds

team 1: buffs were dendro reactions increase EM by 100 for 12s and 60% dendro bonus

team 2: buffs were crit damage +60% and NAs/skills +40%

team 3: buffs were EM +200 and ATK +60% tbh i don't remember if these were mona's exact artifacts and if zhongli had the catch or pjws since i've been switching a lot of stuff around this event; kinda doesn't matter though as they're mostly here to hold things that buff ayaka

so for yanfei i originally ran a 4 wanderers troupe that actually gives her similar substats which i'm showing both of here (somehow the wanderer's troupe build has less EM though LMAOOO) but for this challenge i stole borrowed some pieces from other characters to make a more general build on her and damn. we need some more god damn yanfei appreciation in this house.

her charged attacks were noticeably a bit weaker but she hit so much harder overall with everything else, so i'll probably make this her preferred build from now on as long as the characters she stole pieces from aren't busy <3
