I found this and it could be useful for Grey but I'd love some opinions about cost and what not.

Oh, interesting, formalized rules about part gathering. I was talking to Ella about this earlier lol. Is there a 3.5 or Pathfinder version? Otherwise that's probably fine.
this is the most complete version I've yet to find for this sort of thing. I'll keep hunting but this is really something i just stumbled upon it so I grabbed it before I forgot about it lol. Some of the prices seem a little inflated but i think that can be edited on a case by case basis.
Oh, yeah. Jo and I were talking about using something along these lines as ideas for quests, too. Like an NPC needs certain parts for something they're making. I think it makes sense to have, since you need some of those items to make certain things yourself.
