you're very welcome anon
also keep in mind that these unlock with an extremely scarce resource (basic info core), so make sure that you're only unlocking good keys on your main dolls at the start, otherwise you're going to kick yourself later. you can only equip three at a time per doll, so keep that in mind as well.
eventually you'll unlock every single node on your main dolls for the common and expansion keys at the end of the chain, and also for the stats, but they take time to farm up
