In "A Dark Room" I noticed I can take a Charm when exploring. I never seem to run out of them so I take one every time. I have no idea what they do though. Are they Lucky Charms? Do they increase some kind of stat? Do they make you get attacked more? Less?
If you have one when you're exploring, and you come across some creature (a frog I think) in a swamp, and you give one to it, then each piece of cured meat will regenerate 20 health instead of 10.
