-Human Caravan Driver
These are simple to explain. They are patches of loose sand that will suck a person under the earth in a blink of an eye. So unlike like quicksand, which you have a small possibility to survive, if you step into a Death Pit you don't have much chance. However, they are simple to spot. The pit itself is surrounded by a cone shaped incline, which falls toward the Death Pit.
