I know I need to update that tumblr post (or, more accurately, come out with a new edition of it) but I haven't looked into the 60-70 quests for everything enough yet... and I don't want to make an authoritative post where I'm talking out of my ass, lol.
With regards to soul crystal purposes, I remember a while ago having a conversation about it and we came out with three rough categories of soul crystal as per the quests:
Catalytic: allows the person to do something usually out of their abilities (EG: DRK crystal enabling the manifestation of a Darkside)
Inhibitive: allows the person to use magic that would usually be too powerful for them to wield safely (EG: BLM crystal enabling the person to wield Fire+ without combusting)
Tutoring: solely speeds the acquisition of knowledge for an appropriately attuned soul (EG: PLD soul crystal being given to prospective trainees to speed their learning)
What I didn't ever do was definitively go through the whole list of soul crystals and figure out what category they all fall into...
