Acquire a wolf with fur the color of night. Deglove the skin from its body.
Mix pigment with the water extracted from a raven’s eye and draw the appropriate magical stave upon the skin.
Sprinkle the skin with myrrh and submerge the lot in a well, stave facing down.
Circumambulate around the well, four times, anticlockwise.
Remove the skin and peer deeply into the drawn stave.
You shall receive the Shadow Sight.
Store the skin in a caul until you next intend to use it.
