So, you step on a bear trap, or run over a land mine. You’re doomed, right? You’re a gimp. Forever slowed down. But what if there was another way? What if you could make something useful out of those limbs? What if you could pull an Ash, and attach a chainsaw, or a shotgun to the stump? Or just make a pegleg out of some wood. Maybe craft an artificial hand out of electronics with sufficiently high skill. Such would be awesome.
