So I've gotten 15 or 16 clusters, but I'm pretty sure there's more because when I look on guides there are some that I don't remember getting. However, I've already gone back to several places I've already been to and I'd rather not do it anymore. Does anyone know of a way to track what clusters you have and which ones you don't? I've been looking to see if they have grimoire entries, but haven't found any.
