Winding Key and Diagram are the most valuable items in the game imo. You'll get to a point in the game where you'll complete the collections needed for a Forged Mask Artifact - it increases finding winding key & diagram by 50% for one day. I've also found the collection items needed for this when visiting friends so make sure to visit everyday. There's also a talisman that increases finding them in the event chest - I can't remember what it's called bc I already used it lol but it increases by 30% for an hour and a half. Good luck!
