Wall of Flesh

The Wall of Flesh is an aptly named wall made out of flesh that has the height of the entire map but his vital points (eyes and mouth) are in the open Underworld.

It has two eyes that shoot lasers, and the mouth in the middle spits out leeches which chase the player, usually after the total health of the Wall of Flesh has been reduced.

The Wall of Flesh is also accompanied by small flying enemies called The Hungry, which will detach and throw themselves at the player when damaged enough. The Wall of Flesh only takes Damage at its eyes and the mouth, which means that you have to aim for those when trying to defeat it.

The Wall of Flesh will disappear if he makes it to the edge of the map, however, will always travel towards the center of the map upon being spawned, giving players the maximum space to defeat it.

The boss will only spawn in the Underworld, you have to kill the Guide by throwing the Guide Voodoo Doll in the underworld lava (you have to throw the Doll in the lava, just equipping the Doll and killing him  will not work ). When you see it, it leaves you with a debuff that renders you unable to leave hell, known as the Horrified debuff.

If you die fighting the Wall of Flesh, the debuff will stay on you for whenever you're in hell but it allows you to leave, ''but you cannot respawn the beast unless there is a living Guide in the world with housing. Only then will throwing the voodoo doll summon the boss. If you throw a Guide Voodoo Doll in the lava while The Wall of Flesh is summoned it won't do anything.''

Also, there is a bug where the Horrified debuff might stay on the player even after being killed by the boss, preventing the player from battling it again.

The Wall of Flesh is also summoned by just being in the underworld - meaning that you don't always have to throw the Guide Doll into lava for it to spawn. Though the current mechanic for summoning the Wall of Flesh via this method is not known, just "being in the Underworld" makes it appear.

If you get trapped in a hole while the Wall of Flesh is coming towards you and you don't get out in time, you will get launched through the blocks by the Wall of Flesh so the fight continues, however, this doesn't work if you are at the edge of the world, as it will crush you.

If you attempt to leave the Underworld during the fight by using a Magic Mirror, your character will die, due to the Horrified Debuff. Your lost coins, however, will be found at your spawn point.

When slain, the Wall of Flesh will drop its items in an Demonite brick square and from there they might be collected.

Strategy
As the boss is fought in the Underworld, it is best to prepare beforehand by building bridges over any lava or a long wooden platform in the upper part of the Underworld, in order not to be slowed down by obstacles such as buildings and still be able to attack the lower part of the boss with ranged weapons.. Using Obsidian Skin Potion/Water Walking Potion is also incredibly useful to minimize external damage from the Underworld's hazards. If you lack one of those, a gravity potion should also suffice, but may be more difficult to control.It is also a good preemptive measure to place Torches on the platform, as fighting in the dark can make it hard to see the Hungry and Leeches chasing you.

When the boss is spawned, there is a high chance that it will come from behind you, it is recomended that you make sure the direction your facing is the way you can run. The Wall will travel in a single direction and you cannot go in the opposite direction as the boss will be in the way. Therefore, it helps to go to either end of Hell and summon it from there.

The Wall of Flesh is the hardest boss in the game before it is defeated (it is tougher than Skeletron). Therefore, it is advised to get the best Hellstone armor and weapons before fighting the boss.

The main challenge in fighting the Wall of Flesh is to deal with the Leeches and Hungry that it spawns. It is recommended to kill them using weapons that can deal a vast amount of damage to multiple targets, such as Grenades, Hellfire Arrows and the Demon Scythe. Having a friend help with pinpoint weapons to fend off isolated monsters will also help.

Also be aware that both the Eyes will shoot lasers at the player; beware of these. A Cloud in a Bottle and/or Rocket Boots are a must to fight this boss, or you'll be slowed down from every hill in your path and likely get eaten. Melee weapons do not work terribly well against the wall, due to the fact that the wall can easily damage you at any range.

Since the greatest danger of the fight is Leeches and The Hungry knocking the player into the boss or lava, the Cobalt Shield or Obsidian Shield is a must-have.Although the Molten Armor provides the best defense, in order to deal more damage (which is vital as the boss will eventually push you into unfavorable terrain) one can equip Jungle Armor (which works greatly with Demon Scythe and mana economizing accessories) or Necro Armor (to boost the damage output from guns and bows). Meteor Armor is not recommended for a caster, as it provides significantly less defense.

It is impossible to sneak up on the Wall of Flesh after he has been summoned, as one of his tendrils will grab you from several hundred feet away and fling you in front of him before you can even get in range to attack.

If you are not a very experienced player and want to destroy the wall of flesh, then do this!: Make a VERY long platform over the lava (cutting through buildings if need be), spawn the wall of flesh on one end and as you run down the platform throw as many spike balls as you can. keep a sword handy to destroy the leeches and other dangerous creatures. this will take a while but it will work. every spike ball will do around 7 damage so if you throw 5 stacks (1250) it should do the trick. you can also use a bow and some arrows, boomarangs, or grenades but by using spike balls, you can keep far away and still do the job! after you do that a few times, using the Clockwork Assault Rifle (item wall could drop) is a very easy way to keep killing the thing over and over and over. make sure you wait for the guide to respawn before throwing your voodoo dolls into the lava otherwise nothing will happen and you will lose your doll.

Rewards
When the Wall of Flesh is defeated, it will spawn a large box made out of Demonite Bricks, with its loot inside, destroying anything in the way so nothing gets lost. It will drop money and hearts, and will always drop the Pwnhammer.

It will also drop one of the following items:


 * Laser Rifle (Powerful, Rapid-fire Mana-based laser)
 * Breaker Blade (Gigantic sword, Larger reach than Blade of Grass and about the same damage as Night's Edge)
 * Clockwork Assault Rifle (Fires in 3 shot bursts, while only consuming one ammo)
 * Ranger Emblem (Accessory that adds 15% ranged damage)
 * Warrior Emblem (Accessory that adds 15% melee damage)
 * Sorcerer Emblem (Accessory that adds 15% magic damage)

Also after defeating the Wall of Flesh, Corruption will start spreading through sand, stone, sunflowers and the jungle. This can be countered by the new Hallow biome. This allows access to the new items introduced in 1.1. The time after killing the Wall of Flesh is known as 'hard mode.' This is because new mobs spawn that can kill the player easily.

Bug fixes

 * In the rare case the boss does not spawn at all, the follwing fix can be done. Go into C:/program files86/steam/steamapps/common/terraria and then remove all the data in there and then uninstall and reinstall Terraria through Steam. If you are afraid for your characters lives, they are stored in Documents/My Games/Terraria. You can make a backup from that.
 * One way to fix this bug is to enter/create (then enter) a different world, let any monster besides the WoF itself kill you, exit the game, and come back to your main server where you had the Horrified debuff glitch. The debuff will be gone after dying by a monster in another world.
 * Fighting another boss such as Eye of Cthulhu, Eater of Worlds (on the same world) should allow him to be spawned again
