I'm kind of confused by Delve KIs. Someone told me it was kind of like Voidwatch in that if you don't have the prerequisites you can still participate but you don't advance. Does that mean that if I say want to collect Plasm to buy something. The thing I want to buy also requires having the Semi-pure celadon yggzi KI. Can I get that from just fighting that boss? Or do I have to go in order from the start? Do I have to do Wildskeeper's?
