Wall of Flesh

The Wall of Flesh (WOF) is a boss located in The Underworld. To summon it, a Guide Voodoo Doll must be thrown into the lava. The Wall of Flesh will not spawn if the Guide is already dead.

After defeating this boss, your world will enter hardmode and you'll be facing tougher enemies.

The Wall of Flesh has several attacks. First of all, it always has little things sticking out of branchy tentacles that move towards and damage you. These are called The Hungry. He also has an attack where his eyes shoot lasers, and depending on where the doll was dropped, can appear on either side of The Underworld. Obsidian Skin and Gravitation potions are suggested to help you get by. The debuff, Horrified, causes the Wall of Flesh to drag characters that attempt to escape, such as leaving the underworld or running behind it, to in front of its mouth. Using the Magic Mirror causes you to die, with the message " tried to escape."

If you become trapped in between the boss and a wall, it will squeeze you through those blocks and send you flying. A type of grapple or the Gravitation buff is recommended for this scenario.

It summons Leeches out of its mouth and shoots lasers out of its eyes. It looks like it is made out of left over body parts including 3 fleshy Eye of Cthulhu, which is where many of its attacks appear to be based.

To destroy the Wall of Flesh you must reduce the HP of its three eyes to 0, from a total of 8000. The eyes share a life counter, so shooting at any of the three will deplete the Wall of Flesh's health. The wall of flesh (apart from the three eyes) is transparent to weapons, and shooting the Wall of Flesh there will not deplete its health. Unlike other bosses, this boss does not despawn if you die. It will remain alive until it crosses the edge of the map.

When the Wall of Flesh is killed, it leaves its drops in an enclosed box of demonite bricks. This way, the drops do not fall into lava, saving the player a lot of trouble.
