What does that mean -cannot be stolen?
For example "pickpocket ring at large" says that (unless you roll succesfully) you must give up your most valuable item or all money.
If your most valuable item cannot be stolen unless you allow it, does that mean that instead of it you can give second most valuable item?
If you don't have money, can you give 0 money instead of items and vice versa or do you allways have to give something?
And does "cannot be stolen item" count with total items when you discard half items because you got your stamina or sanity to 0?
If yes I don't see the use for that item ability.
Lame item ability.
