[GMST] [0.99] Chaos

Excuse me, in the past I remember the capability to "unlock" the mysteries of Use items that when used resulted in a random other item appearing and the percent probability of said item. Such items included things like Secret Mastery Books, Pharaoh's Treasure Chests, chests in general among others things. My question is: With PvP's introduction, Mystery Recipe (ID: 2028062) and to a lesser extent Mystery Scroll (ID: 2028061) were introduced and at one point Spadow mentioned he got 130 Bowman Glove Recipes from it, can the same process you used previously be applied to tease the probability and prizes from these items? For future reference, what are the limitation of your sight into these type of items?

Also, at your leisure, some other similar items I'm curious about include: Any of the Fruits or Diamonds from Orange and Gemstone Imps (IDs: 2028041-2028060)
