One of the most unusual features of Icelandic folklore and medieval grimoires are the necropants. These were literally a pair of pants made from a dead person’s skin from below the waist.
You might ask yourself why would anyone wear such a thing? Well, the necropants represented a supernatural way to gather wealth, but the process was quite complicated.
First of all, the wizard had to make a pact with a living man and get his permission to dig up his corpse and skin it from the waist down in one piece. The skin must remain completely intact, with no holes or scratches, else the necropants would not work. After having fashioned the necropants, the wizard had to slip right into them and the necroskin would become one with his own.
Next, he had to steal a coin from a poor widow, either on Christmas or Easter and place it inside the scrotum of the necropants together with a magical stave drawn on a piece of paper. By doing so, the scrotum would never be empty and the wizard will benefit from an endless flow of prosperity.
However, he had to get rid of the necropants before he died. Therefore, the wizard had to look for someone willing to take the pants and put his leg into the right leg before the wizard steps out of the left one.
The necropants would keep on drawing money for generations of owners.
