550 cord would make good snares because it is so strong and the tight weave makes it kind of “slippery”. I would not advise anyone to try and climb with it however. I tried that myself and ended up with a lot of rope burns and still would have been at the bottom of the pit. 550 cord can also make a decent tourniquet, especially with the aid of a small stick. You simply tie a reasonably tight loop between the wound and your torso, insert the stick and then twist the stick in a circle as if your are turning off a water faucet. An arm or a leg can be made to turn blue and cold to the touch in a minute or two like that. Once the stick has been tightened to the proper amount a knot around the limb and the stick hold the tourniquet in place. In game terms, perhaps a stick and a piece of 550 cord could be used to stop bleeding in a way that was less painful than cauterizing the wound. I don’t know if there are any other forms of snaring besides bear traps atm. Maybe 550 snares could slow down enemies like a bear trap, but do no damage. That way they are still useful in a different way from the heavier bear traps.
