Really don't think it's something a pure mortal could use, here's something from the custom power list that does the same thing:
BAG OF TRICKS [-1]
Description: For whatever reason, you have access to a few minor magical trinkets.
Skills affected: Contacts, Resources, Burglary, Lore.
Effects:
Enchanted Items: You have four potions, each with a strength equal to your Contacts, Resources, Burglary, or Lore skill. You may not increase their strength in any way. At the beginning of each session, you must declare which potions you have on hand.
More Trinkets [-1]. You have four additional potions. Furthermore, you may choose to leave potion slots open to be filled later with Declarations.
