Hello, I’m currently in the chapter 221 and it seems to me you forgot about Jason’s sword(the one he received from Gary). The party was getting ready for going to Bronze rank(buying equipment, getting ingredients for re-summoning familiars, getting materials for evolving growth items), even though the sword was a growth item it wasn’t mentioned in the preparations.
Ps: This is not a complaint, I’m simply trying to help you since your story has a lot of things to keep track of.
