My idea !
I thought about this for 5 seconds and decided I like it.
As long as it’s not a huge amount, I think it’s a good idea. My concern would be that a blob could take advantage of it, but frankly, if you have a blob you can take a camp and run back super quickly anyway. This idea would be just a nice little way for small groups and soloers to supplement supply – which is why it might not even be worth spending dev time implementing it.
