A Werewolf game encountered a little problem coming from the wording of the "Rite of Talisman Dedication", that hasn't really changed since 2nd edition:
Cut to the base effect, one can bind an object or set of contextually linked objects (a set of clothing; a box of ammo; a gun, its magazine, and ammo in it) to carry them over to the umbra. What counts as a linked set is pretty much GM-Fiat, but exactly here things get very very wonky, because of containers such as a wallet, purse or backpack.
To start it off, our group of players has little to no backpacks and other containers as bound objects, and about half of the group are Bastet. The group has just recently formed the Ahadi pack equivalent, allowing large scale umbral access via the same backdoor a Mountain Sentai uses: one pulls the group through. This obviously leads to widespread lack of Umbral experience, those that do have Umbra experience are characters that are pretty down on the possessions side, so they usually don't have much to look after - bind the wallet, clothes and cell phone and you are kind of safe was our general guideline. So when we encountered our problem it was with a jeans pocket.
Discovering the problem
We all had assumed that a pocket would keep its unbound contents because money stayed in the wallet even as the exact contents changed over time. We quickly came to agree, that a wallet with money stays a wallet with money, no matter if it is still the same money and thus it stays the same contextual item set: money in a dedicated container.
Now, we had assumed the contents of the clothing pockets would be kept in them as well. However, our GM thought it was a nice plot twist that we loose a note on an unbound slip of paper at entering the Umbra as it was tucked into one of the char's pockets. We rolled with it, someone had to backtrack to pick it up again.
Now, our dilemma is to find a consistent ruling on what makes an object having to be bound separate from another set to come with you and when does an object merge into an existing set without any need of doing so (money into the money pouch).
As said, we did roll with the GM after a moment of confusion but it made us wonder: Is there any notion of how containers and pockets should be handled with the Rite of Talisman dedication besides the rites (somewhat wonky) description in the Werewolf books? If there isn't, an idea how to resolve this proublem without invalidating the Money & Wallet part as well as the Lost Note part would be very nice.
I just managed to skim through W20's umbra chapter and the Revised core rules, but couldn't find any hints about the intended container behavior in those, and the behemoth of available books gives me a headache to search through, so I am in need of the collective brainpower of the Hive-Memory of Stack Exchange.
