As per item #4) When you right-click on them they would be consumed and you would get a Formula/Technique of that type and tier....
Im hoping the formula is not attuned to the person that opens it ?.
Also could something along the same lines be done as w/ the presents of past you get a bunch of orniments and you go to venders and trade them in for what you want , or the "orniments" have a HV to them.
After re-rereading this , I'm thinking maby the formulatron will except either coin or "orniment" type things.
Hopefully this came out slightly clearer then mud..
