im currently trying to get my Kaeya to lvl 90

in only suffering a little bit while doing so. everytime i enter the area of the cryo regisvine, an angel falls face first down a flight of stairs and knocks its teeth out (and also loses its wings). i also refuse to fight the cryo cube unless im with my friend who has a lvl 90 Yanfei. i will get kaeya to lvl 90 though, but i will be doing the process with much reluctance due to me not enjoying fighting bosses
