How do I get charms in a dark room?
I came across the swamp in A Dark Room but I don't have any charms. How do I get them?
You can get charms just by checking traps. The more traps you have the more resources you will get. So you get a higher chance on getting a charm by setting up as many traps as possible. Also using Bait does increase the yield of your traps as well.
For more info, check the wiki on charms and traps. Even though there is really not much more to it.
