Impenetrable Wall
The Wall of flesh is a strange monster to encounter at first. He has an eye on the top and bottom and a beak-like mouth in between. First I recommend you read the article about Armor the Fiery Greatsword and the Night’s Edge. Now, Make yourself a nice set of Molten armour and a Fiery Great word or a Night’s Edge.
Now walk around in the underworld to find a Voodoo demon. They will have a 100% drop chance of a voodoo doll when the demon is killed. Then wait until you have full health. (Note: Having your health maxed is really helpful, and having a long stone path stretching across the underworld.) Now if your on PC, Xbox, or Playstation you need to throw the doll into lava. If you have it on a mobile device you need to eat it in the underworld.
The wall of flesh requires a great amount of different weapons to defeat: a Melee weapon like a sword, a magic weapon like a diamond staff, and a ranged weapon like a repeater or a gun. Now once he spawns you should constantly just keep spamming him with weapons and don’t pay attention to the hungry. Now you should try not to die. You might need hermes boots to run fast away from him.
