The Wall Of Flesh

Info
The Wall Of Flesh (WoF) is the hardest boss in Pre-Hardmode, and defeating it will unlock Hardmode. It is comprised of a long wall of living flesh, with two eyes on the top and bottom and a mouth in the middle. Behind, it has many tails comprised of entrails. Latched onto it are many small mouths which are known as The Hungry due to their never-ceasing hunger.

The Wall will attack the player in many ways. The actual 'Wall' will slowly move to the opposite side of the map that it was spawned on, hurting the player severely upon contact, and flinging them forward as to prevent them getting behind the wall. The Hungry attached to the wall will swarm toward the player, and try to bite them, though this is a negative effect, it makes it easier to destroy all of the hungry. The mouth will spawn Leeches, a burrower type enemy that will attack the player ferociously. The eyes will begin to shoot lasers (similar to those shot by the Laser Rifle, that The Wall does in fact drop) at the player when The Wall begins to lose damage. Eventually, the Lasers will quicken to the point where they are hardly stopping. The Wall does not drop its contents on the floor when it is defeated, as the Pwnhammer may fall into lava, making further progression almost impossible. Instead, it makes a small box of Demonite/Crimtane bricks with its drops inside of it.

The Wall Of Flesh is summoned by throwing a Guide Voodoo Doll into lava when the guide is alive. In the old Mobile version, a glitch could occur that made the WoF spawn without eyes, a mouth, leeches or any hungry and therefore made it invincible and impossible to survive.

Strategies

 * You cannot house a Nurse or Dryad for this particular fight, but is still recommended to make a long, flat arena, with heart lanterns, Campfires and Fireflies/Stars In Bottles.
 * Using the Imp Staff is incredibly helpful, since it attacks The Wall constantly and is completely invincible.
 * Using items dropped by Queen Bee such as The Beekeeper, The Bee Gun, The Bee's Knees, Honeycomb, Honeyed Goggles and Beenades would be incredibly useful for The Wall Of Flesh, due to the swarming nature of bees.
 * The Hungry and Leeches always (1/5 chance in Expert and Master Modes) drop one heart, so prioritise them if you are low on health and have the Potion Sickness debuff.
 * Using Ironskin, Swiftness and Thorns Potions is highly reccomended.
 * On multiplayer, instead of building a bed to respawn, use Wormhole potions to teleport directly to the fight. Keep in mind that only people on the same team may teleport to each other using Wormhole potions, but that does not count two neutral Players.
