Wall of Flesh



The Wall of Flesh (aka WOF) is the final and strongest pre-Hardmode boss, spawnable only in The Underworld. Once it is defeated, the world permanently converts to Hardmode, which brings new content and challenges.

To defeat the Wall of Flesh, the player must attack either its eyes or its mouth. They all share the same life counter, so attacking any of the three will deplete the total health of the boss. However, the eyes have less defense (thus taking more damage) than the mouth. Its other parts are intangible to weapons, so attacking those will not deplete its health.

Its Bestiary entry states: "Serving as the world's core and guardian, the towering demon lord exists to keep powerful ancient spirits sealed away."

See below for information on the two exclusive debuffs from the boss, Horrified and The Tongue.

Summoning
The Wall of Flesh is summoned immediately when a Guide Voodoo Doll is destroyed by being dropped into lava in The Underworld while the Guide is alive, killing the guide. ((Take note that if you kill a voodoo demon and it drops into lava without the player picking it up it will still spawn the wall of flesh)) Alternatively, burning the guide alive in the underworld will also spawn the wall of flesh, but dropping the doll into lava outside of Underworld or when the Guide is not alive will not spawn it, and the Voodoo Doll will be destroyed with no effect.

The Wall of Flesh's sweep direction is determined by its spawn location. Spawning it anywhere left of the center of the world will cause it to sweep from left to right, while spawning it right of center will cause it to sweep right to left (regardless of the direction the Doll was thrown). Maximum fight space can be achieved by spawning it at the extreme right or left of the world, though these areas have fewer natural structures and may require additional lava survival gear or construction. Be aware of the fact that The Wall of Flesh might not fight but just leave the battle if you spawn him too close to the edge

Attacks
The Wall of Flesh is very large, occupying the entire screen vertically. Once spawned, it slowly sweeps across the map in a single direction, forcing the player to constantly move away for the duration of the fight, while also contending with the Underworld's usual hazards. It must be killed before it reaches the other end of the map, otherwise, it will despawn and all players in The Underworld will die (with the unique death message "").

Once the Wall of Flesh has spawned, all players within 1800feet will be inflicted with the Horrified debuff. The debuff lasts until either the player or the Wall of Flesh dies. If a player dies and then returns to the battle, they will again be inflicted with the debuff. While this debuff is active, players cannot flee the battle, i.e. attempting to escape the Underworld via a Magic/Ice Mirror, Recall Potion, Teleporter, or running far ahead of the Wall and leaving, will cause the player to die instantly with the unique death message ""

Attempting to leave the Underworld or to get behind the Wall of Flesh will inflict The Tongue debuff. When it is activated, a tendril will snatch the player and draw them into the Wall of Flesh's mouth, ignoring blocks in the way, and dealing high damage to the player. The player will be unable to move or use items while the debuff is active.

The Wall of Flesh moves faster as its health depletes, increasing in speed after reaching 75% ( / ), 50% ( / ), 25% ( / ), and 10% ( / ) of its health. In, it accelerates even further with additional increases at 66% , 33% , 5% , 3.5% , and 2.5% maximum health.At extremely low health levels, it can reach up to 50mph (as compared to the Hermes Boots at only 30mph, Lightning Boots at 34, and the Bunny Mount at 38).

Additionally:
 * The Wall of Flesh has small mouths called The Hungry, each attached by a long vein, which move towards and damage players. As the Wall of Flesh's main body takes damage, they deal more damage and become more resistant to attacks. When sufficiently damaged, they detach and fly towards players at high speed.
 * In Expert mode, the Hungry respawn as long as the Wall of Flesh is alive.
 * The Wall of Flesh's eyes fire lasers. As its health depletes, the lasers increase in damage and frequency, to the point where they barely stop.
 * The Wall of Flesh "burps" Leeches from its mouth that chase players. These will always drop Hearts when killed.
 * In Expert mode, Leeches only have a 20% chance to drop hearts when killed.

Aftermath
When the Wall of Flesh is killed, it leaves its drops in a midair frame of Demonite Bricks for Corruption worlds, or Crimtane Brick for Crimson worlds. One drop is always the Pwnhammer, which is required to progress early in Hardmode.
 * In the, the frame is always made of Demonite Bricks.

Hardmode
After defeating the Wall of Flesh for the first time, the status message "" displays and the world converts to Hardmode. Hardmode brings new biomes, new and tougher enemies, and a vast array of new equipment.

Two diagonal stripes of Hallow and Corruption or Crimson form in a "V" pattern from the center of the Underworld, all the way to the surface. Corruption/Crimson and Hallow will spread at a much faster rate, eventually covering large areas of the world if no action is taken.

Master Mode

 * In Master Mode the Wall of Flesh has 16800 health and is faster than ever, so beware.
 * When in Master Mode, the game will always provide a sixth accessory slot, and using the Demon Heart will give you a seventh one.

Tips

 * If you are not ready to fight the Wall of Flesh, avoid letting a Voodoo Demon drop its Guide Voodoo Doll into Underworld lava.
 * If the Wall of Flesh was recently summoned or the Guide was recently killed in some other way, make sure the Guide has respawned before attempting to summon the Wall of Flesh again. The housing menu as well as the map can be used to see if the Guide is present in the world.


 * Mobility-enhancing items, such as Gravitation Potion, Rocket Boots or one of their upgrades, and various hooks can make traversing The Underworld much easier. Similarly, items like Obsidian Skin Potions, Lava Charm, Lava Waders, or an Obsidian Rose can mitigate The Underworld's many lava pools and other ambient hazards.
 * Heart Arrows will freeze the Wall of Flesh in place, as long as the arrows hit its mouth.
 * Beenades and Molotov Cocktails are highly effective throwing weapons against the Wall of Flesh, especially in.
 * Melee weapons are not generally recommended for fighting the Wall of Flesh for the first time, because the close range of this class results in a sizable amount of contact damage. Certain melee weapons with extended range, like the Dark Lance or a, might prove useful.
 * Equipment that inflicts On Fire! are effective against The Hungry.


 * An effective and common terrain preparation consists of building a long bridge (at least 500 tiles long in normal mode). Wood Platforms or Hay blocks are suitable materials due to their abundance. Ruined Houses and hills of ash on the bridge should be cleared to avoid getting stuck during the fight.
 * Making the bridge out of Explosion-proof tiles (such as Dungeon Bricks) and using Dynamite can be extremely effective if the player times their throws well.
 * For rangers, a hilly platform can help avoiding the boss's lasers. Shoot at the Wall of Flesh from the top of one hill (or slightly behind it) and move to the next hill once it gets too close.
 * The Wall of Flesh reacts differently to Ash Blocks. Using these for the bridge will cause both eyes to constantly stay above it.
 * Build a long Minecart Track instead of a plain platform because the player can keep up with the boss. This is even more useful in because of its high speed  (50mph) towards the end of the fight. Even when using the default Wooden Minecart, the player can travel faster than the Wall of Flesh, at 51mph.


 * Focus on The Hungry first before significantly damaging the Wall itself. The Hungry's damage and defense are boosted as the body takes damage, which will make them more difficult to kill if left for later.
 * Attacking the eyes causes the most damage, as they have the lowest defense.

Trivia

 * The Wall of Flesh was inspired by the Demon Wall from the Japanese science fantasy video game series.

 * The Destroyer and the are the only other two bosses that do not despawn when the player gets too far away.
 * The Hungry are the only Underworld enemy not immune to the On Fire! debuff.
 * Because killing the Wall of Flesh creates strips of Hallow and Corruption/Crimson, if it is defeated near the middle of the map, it may drop a Soul of Light or Soul of Night on death, proving that the world is in fact converted to Hardmode before the status message displays.
 * The lead developer of Terraria, Redigit, has confirmed that the Guide is the Wall of Flesh on the official Terraria Discord.
