I've been thinking about this a little bit and i thought making traps for hunting and defense might be a cool idea.
It would be a new skill you would need to learn and it would allow you to make traps such as snares and bear/ leg traps. You could make snares for catching smaller animals like chickens and rabbits (maybe foxes to?). Maybe a dead fall traps (a big stone propped up with a stick and baited so an animal would go under the trap and get crushed by the rock). Some larger traps like a leg trap or bear traps, These would keep an animal held in place and maybe hurt them/ kill them if there smaller animals. Maybe even a pit fall that you would need to cover up and check to see if anything has fallen in.
Maybe some defensive traps traps could be made. Something like, again, a pit fall or spike fall. You could also have spring traps that would activate if someone stepped on a trigger point. These traps would be something like a tied back branch with wooden stakes on it that would spring forward and hurt someone.
A lot of the bigger game traps would be effective enough on a person. A persons ability to hide a trap would be based off there stealth and perception and the ability to see a trap would be based on the same if not than a perception and exploration? That's of course assuming you would be able to use them on people.
Not sure how well these could be implemented if people liked the idea but i thought it was worth putting out there. Let me know what people think of the idea
