The voodoo poppet is what gives the practitioners of poppet making a bad reputation. This poppet is used as a way to cause negative effects on the linked being.

Swinging the poppet around will cause the linked person or creature to be thrown around violently. Charge with right-click for a stronger effect.

Sneaking and using the poppet with bone needles in your inventory, will stick one of them into the poppet. This will cause a small amount of magic damage to the target.

Holding the poppet underwater may also cause the target to take drowning damage along with the player.

Finally, using the poppet on lava will set the target on fire, destroying the poppet in the process.
