Guide Voodoo Doll

The Guide Voodoo Doll is an accessory that allows the player to harm and kill the Guide NPC, and summon the Wall of Flesh. The Guide will always respawn after being killed. The Doll is always dropped by Voodoo Demons in the Underworld.

When the Doll is equipped as an accessory, it becomes possible for the player to kill the Guide with weapons (normally, NPCs cannot be harmed by player weapons). If the item itself is destroyed by Lava, ie. the player throws the Doll into lava, the Guide dies immediately.

If the Doll is destroyed in Lava within the Underworld, the Guide dies and the [Wall of Flesh, the final pre-Hardmode Boss, is summoned. The Guide must be alive before the Doll is destroyed, otherwise the Wall of Flesh will not appear.

Trivia

 * In popular culture, a voodoo doll is a figurine resembling a person, which can be harmed in order to magically inflict harm on the person being mimicked.
 * Before the Wall of Flesh is defeated, several NPCs sometimes make reference to the Doll's function:
 * Arms Dealer: "I heard there is a doll that looks very similar to [Name of Guide] somewhere in the underworld. I'd like to put a few rounds in it."
 * Nurse: "How many times will [Name of Guide] come in with severe lava burns?"
 * Guide: "When you are ready to challenge the keeper of the underworld, you will have to make a living sacrifice. Everything you need for it can be found in the Underworld."
