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. However, if you fail against this boss, the Guide will not respawn, but you will not enter Hardmode.

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."

It possibly licks you with The Tongue as a form of attack, or may drop the The Tongue as an item upon death. It summons Leeches out of its mouth and shoots lasers out of its eyes. It spawns in The Underworld. 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.
