A couple things i wanted to mention. Firstly, they should be craftable if you can get your hands on any kind of wood, any type of fat or flammable fuel, and any type of cloth or “wrapping” material. Maybe the quality of the resources dictates how much durability the torch will have. This brings me to my next point, torches should run out of durability as they are used. They wouldn't last forever although for the sake of gameplay they might last significantly longer than their real life counterparts.
