Wall of Flesh



The Wall of Flesh 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 don't take damage.

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

Summoning
The Wall of Flesh is summoned immediately <abbr title="First the position of the Guide Voodoo Doll is checked. If that position is within 75 blocks of a player's X coordinate, it will check the next position 1 block closer to the world border. This will repeat until the position checked is not within 75 blocks of any player's X coordinate, or if the position is 20 blocks from the true world border (Main.maxTilesX and 0) After the X position is found, if the tile is obstructed or has a liquid level above 100, it tests the block 1 block under it. If it is still obstructed, it tests the block 2 blocks (then 3, then 4...) under the new tested block, until a valid block is found or it exceeds the world border. After which, it selects the last obstructed block to spawn the Wall of Flesh's mouth. If it exceeds the world border, Wall of Flesh's mouth is spawned at the Underworld Roof (y = 180, underworld is 182 blocks tall from true world border to ceiling)">75 blocks away from all visible players when a Guide Voodoo Doll is destroyed by being dropped into lava in the Underworld while the Guide is alive, killing the Guide. 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. In the, the Wall of Flesh can also be summoned by letting the Guide be killed in the Underworld while the Guide is in contact with lava. Using this method, the Guide can die by any means, either from a player, an enemy or the environment, as long as he is touching lava when he dies.If a Mediumcore player dies in lava (in the Underworld, and Guide is alive) with a Guide Voodoo Doll in their inventory, then the Wall of Flesh will be summoned.

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 it 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, if possible. 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 "" Exiting the game and re-entering the world allows for escape, but causes the Wall of Flesh to despawn.

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 up to a speed of 56 mph, 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 41mph (as compared to the Hermes Boots at only 30mph, Lightning Boots at 34, and the Bunny Mount at 39).

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.
 * The Hungry will always drop a Heart when killed. In Expert mode, they only have a chance to do so.
 * 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.
 * The Wall of Flesh "burps" Leeches from its mouth that chase players. These will also always / drop a Heart 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 for Crimson worlds. It will always drop the Pwnhammer, which is required to generate Hardmode ores in the world. (Generated by destroying altars)
 * In the, the frame is always made of Demonite Bricks.
 * In, its dropped Treasure Bag includes a Demon Heart (only if the player opening it has not consumed one yet), which provides the player an additional (6th) accessory slot.
 * In, the player starts out with a 6th accessory slot, so the Demon Heart adds a 7th.
 * The Demon Heart can only be obtained and used once. If the player has already consumed one, additional Treasure Bags will not yield additional Demon Hearts, and the acquisition of a second Demon Heart will still not allow it to be used.

Hardmode
After defeating the Wall of Flesh for the first time, the status message "" displays and the world permanently 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.

Tips

 * If you are not ready to fight the Wall of Flesh, avoid both killing a Voodoo Demon while it is above lava, or on the letting the Guide get killed in lava.
 * For this reason, try to avoid killing Voodoo Demons in the outer quarters of the world, as there are no Ruined Houses, and thus more lava on the far edges of the world.
 * If you accidentally do end up summoning the Wall of Flesh, note that it is slow to start, and can be easily outrun via the use of speed enhancers, such as a Swiftness Potion.
 * 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 quickly check if the Guide is present within the world.
 * If one wishes to farm the Wall of Flesh, consider making a house in the underworld above lava with actuators on the floor or wire a teleporter. The Demon Conch can also be used to teleport to The Underworld.
 * As soon as the guide is inside the housing, activate the actuators then quickly deactivate them. This way, the guide can respawn in the same housing and is ready to be farmed


 * Mobility-enhancing items, such as Gravitation Potion, Rocket Boots or one of their upgrades, and various hooks can make traversing The Underworld much easier. Also, flying mounts such as the Honeyed Goggles are good to go over the pools of lava. 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.
 * will freeze the Wall of Flesh in place, as long as the arrows hit its mouth.
 * Beenades and Molotov Cocktails are highly effective consumable ranged weapons against the Wall of Flesh, especially in.
 * Melee weapons are not 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 and even more in Expert or Master). Wood Platforms or Hay blocks are suitable materials due to their abundance. Ruined Houses and hills of Ash Block 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 a 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 will always try to stay above 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 will not despawn when the player dies in singleplayer.
 * 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. This explains the relevancy of his death to the appearance of the boss.
 * The aforementioned confirmation is consistent with the fact that the Wall of Flesh is directly referred to as male with the use of "him" in a loading screen tip.
 * However, the Steam trading cards, and even the Guide himself, say that he is instead a sacrifice to the Wall of Flesh.

 * It is one of the only Bosses that drops mounts in Master Mode. The other Master Mode-exclusive mounts are dropped by Mini-bosses.
 * The veining at the back of both eye and mouth is identical to the veins trailing the Eye of Cthulhu.
 * It is interesting to note that the Wall of Flesh's mouth somewhat resembles that of the Eye of Cthulhu's second phase.
