Mojos are often fashioned in form of grisly trophies, like the Necromancer's Shrunken Heads of Diablo II. These can be voodoo dolls, skulls, severed heads, otherworldly artifacts, or even living beings, like serpents. Through these, the Witch Doctor enhances his link with the Unformed Land and can hear the spirits more clearly. Many are nothing more than talismans (and images of the enemy's future for them to behold and tremble before), but some are artifacts of unspeakable capabilities, or even sentient monstrosities taking the form of a simple charm.
