Wall of Flesh

The Wall of Flesh is a boss that can only be summoned and fought in the Underworld. Most of its stats are unknown other than its health, which sits at a hefty 8000.

It's a big wall made out of flesh that spans the height of the open Underworld. It has three Eyes of Cthulu attached to it; the bottom and top one shoot lasers, and the middle one spits out worms when you get too close. The Wall of Flesh also is accompanied by small flying enemies called The Hungry. Each one has 240 health and looks like the underworld version of a Man Eater.

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 equiping the Doll and killing him will not work). When you see it, it leaves you with a debuff that leaves you unable to leave hell. If you die fighting it, 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.

Strategy
&nbsp As the boss is fought in the Underworld, it is best to prepare beforehand by building bridges over any lava. Using Obsidian Skin/Water Walking potions is also incredibly useful to minimise 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.

When the boss is spawned, it 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.

Making a smooth passage through the underworld without buildings in the way will also minimise risks.

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

A Minishark with Silver Bullets and/or a Magic Missile are one of the most effective ranged weapons. Melee weapons are almost useless as the Wall of Flesh is fast-moving and and will shoot out Leeches when you get too close.

Rewards
When the Wall of Flesh is defeated, it will spawn a large box made out of Demonite Bricks, with it's 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.

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 should be to enter a new world an spend some time there (possibly dying in that world by any way, not by the Wall of Flesh), exit the game, re-enter and open the world where you had died. Another, also needing confirmation, is to leave the world immediatly before or after your death, then rejoin. The wall should respawn normally then. (this fix is unconfirmed)
