Guide:Wall of Flesh strategies

The Wall of Flesh (or WoF) is the final Pre-Hardmode boss. It has two eyes, which shoot lasers at you, and one mouth. It also has many small creatures near it called The Hungry. They are connected to the WoF with long tendrils, which break once the Hungry take enough damage, releasing them to fly towards you.

Once you have beaten the Wall of Flesh, you will receive an ominous message and your world will enter Hardmode.

Summoning The Wall of Flesh
To summon the Wall of Flesh, go to The Underworld, kill a Voodoo Demon carrying a Guide Voodoo Doll and collect it. Drop it into a lava pool in The Underworld to awaken the WoF (Wall of Flesh). A word of warning, the WoF can accidentally be summoned by killing a voodoo demon over lava and allowing the voodoo doll to fall into the lava; this will not work if the Guide is not currently alive, you still have the Horrified debuff from a previous fight or you throw it in a lava pool that is not in The Underworld. Note: In the mobile version you just tap the voodoo doll in your inventory to summon the Wall of Flesh or drag it out of your hotbar.

Terrain preparation
There are multiple approaches you can take for fighting this boss, each having several strategic implications. One terrain strategy is build a long bridge to go through half the map, then summon it on the left.

Full Preparation
You will benefit from preparing the area ahead when fighting the Wall of Flesh more than with any previous boss. An optimal arena is a perfectly flat land bridge of length at least 1000 tiles, although you can need as much as 2000 with poor weapons and/or armor. It is also a good idea to make your bridge out of wood platforms, as ranged attacks can hit all parts of the WoF this way. But by building the platform out of ash will allow you to change the position of the eyes. This is helpful for targeting the eyes as they have low defense. On mobile, as the WoF will not adjust its parts to appropriate height, you may also build your bridge relatively high up, at ~50 blocks below the Underworld's upper boundary. Lighting is relatively optional as the area will be well-lit from lava and other effects. Note that the height of the bridge does not especially matter, as the Wall of Flesh will move its eyes and mouth to the appropriate height for combat on its own (Unless you are on mobile).

Headroom to maneuver above the bridge may be useful, and additional wooden platforms can provide further mobility options, especially types for melee users. Also, if you have access to the Frostspark Boots, making the arena out of ice will allow much faster speeds to outrun the Wall.

It also helps tremendously for players who tend to get hit often(or just as a precaution) to station the nurse about halfway through the arena to heal yourself, even if you have the potion sickness debuff. If the house is small enough, you can jump over it easily. The nurse dying is unlikely, especially if she is in her house and the doors are closed; even without her in her house, the wall should pass over her without serious damage.

If you can jump boulders, then you should set up a few at the beginning of the run and wire them to a pressure plate in the course, so you can step on the pressure plate, and the Wall of Flesh gets hit by a few boulders, but them hitting you can seriously affect the battle, because they do a lot of damage. Explosives (or just thrown Dynamite) can be used in a similar manner for even greater damage. Grenades or Beenades are suggested when using a bridge, or you can also set up heart statues connected to pressure plates to heal up.

If using below optimum armor, or to help reduce the number of potions you will need, position Campfires every so often along your bridge.

One strategy which has worked for some players is to build a 3-7 block high tunnel so that the WoF can not use the laser eye attack since it cannot shoot through blocks. For regeneration purposes use full crimson armor and campfires every 20 blocks to help. A good weapon to use is the diamond staff but if you have multiple people the ruby staff will work as well. If you intend to solo the WoF use molten armor. Only Use Shadow/Crimson armor if you are a very good at dodging the WoF's Lasers and the hungries.

Another strategy for people who farm the WoF is a tunnel just tall enough for the mouth to be vulnerable while actuated dart, super dart, or flame traps can be put in the inactive state (allowing the use of traps on both sides of the world to shoot through each other and along the path) under and above the mouth tunnel, effectively shooting the eyes and avoiding the lasers while the player can focus on the mouth and the leeches.

Partial Preparation
If a full arena isn't desired, or you're not interested in wasting time on a world you don't intend to keep, you can make less extensive preparations. Run your bridge over any lava pits, make sure there aren't any especially difficult jumps to make, and clear a path through any major outcroppings. You may want to extend your work to closer to 750 blocks, as the fight will drag on while you jump over obstacles. (If this is not your first time killing the WoF, then a cutlass with good armor will work, provided you have healing potions ready) It also would be a good idea to bring restoration potions since they heal mana and health. Regular restoration potions are recommended.

Partial preparation favors ranged combat, as you won't be within melee range often. You also will need to keep a bigger distance to account for any slow climbing you'll need to do. If you have large flat segments, those would be good times to close to melee.

It's preferred to have someone assist you in killing the Wall of Flesh, though it is possible without help.

The Horrified debuff has the effect of instantly killing you when you use your Magic Mirror, it does so after you return to spawn, allowing you to recover your money and (on mediumcore) items instantly. Obviously, it's a last-ditch strategy, and one that serves no purpose for hardcore players.

Armor
Molten armor, especially considering you will have to use this once hardmode starts. Meteor armor, Jungle armor, Necro armor or Bee armor are valid options if you're specializing in non-melee weapons. Crimtane armor is also good with its increased life regeneration. Even if not using Molten armor as a main armor, it's best to have a set to swap into in case things get hairy once you initiate hardmode. Molten armor is the best armor to use when defeating the Wof.

Weapons/Items
Some weapons/Items that will help in some ways are: Vilethorn, Hornet Staff (if You have Bee armor), and Ammo Box (If you use guns, you will need a lot of them), Molten Fury (If Console/Mobile use Sharanga), Flamarang, Magma Stone, (to do fire damage) and Fiery Greatsword and finally Beenades.


 * The Thorn Chakram,The Enchanted Boomerang and Beenades are also good for killing the Hungry.

Melee Weapons
A primary concern about melee in this fight is that you are constantly moving away from the boss. As it is impossible to back up while swinging a sword, weapons like the Night's Edge and Phasesaber are forced to stay dangerously close to the boss and catch it on the backswing if they wish to damage it directly. This would be nearly impossible without full terrain preparations.
 * A melee weapon especially helps when fighting the numerous Hungries, as one swing can hit many at once. Balanced characters may wish to start with a melee weapon to clear out the Hungries before switching to range or magic to fight the boss. The Wall of Flesh has low defense, so the player isn't limited to necessarily using the strongest weapon that they have available.
 * You can also use a Flail. The Sunfury is recommended because it is the strongest of its tier in pre-hardmode. This is a good choice because it can inflict multiple hits on the Wall of Flesh. Same applies to the Dark Lance. Getting either the Dark Lance or the Sunfury is recommended if the player intends to focus on melee.
 * Possibly the best choice as a weapon for fighting the WoF is to use a Yoyo. Using a yoyo allows the player to run away from the WoF while also attacking it from a distance, once all of the Hungry are killed. It's recommended to use a stronger yoyo such as the Valor (from the Dungeon) or the Cascade (dropped by Underworld enemies after Skeletron has been defeated). Also, using accessories related to the yoyo, such as String and Counterweights can also be beneficial.

Ranged Weapons
The ranged approach is safer but slower for this fight. When choosing ranged weapons consider taking the Necro armor, as the set bonus will reduce the ammo consumed, and the lowered defense should be mitigated by the distance between you and the wall.
 * A Hellwing Bow is a fairly common find pre-Wall of Flesh and is an excellent weapon to use against it, dealing high damage with extremely cheap only Wooden Arrows.
 * Alternately you can use piercing or exploding ammunition, such as Meteor Shots, Hellfire Arrows or Jester's Arrows. Gun users will want to use a Phoenix Blaster, Minishark or possibly even a Star Cannon (it takes about 150-160 Stars to kill the WoF and the Hungry; this makes the fight fairly easy if you have been hoarding them.). Bow users are best off using a Molten Fury, Hellwing Bow, The Bee's Knees, or Sharanga . With any choice, you will want to bring a significant amount of ammunition (about 1,500 to 2,000) to ensure you do not run out. Other bows and guns should be avoided.

Magic Weapons

 * A Waterbolt, Ruby Staff, Diamond Staff or Demon Scythe can deal a hefty amount of damage to the boss, while also providing piercing to quickly clear the Hungry. Magic weapons such as Space Gun consider using Jungle armor or if made Meteor armor instead. If you just want defense, you can use Molten Armor or the highest armor for defense.
 * Flamelash and Magic Missile perform poorly in this fight. The rate of damage is abysmal when dealing with Hungries or the wall itself. They are good at hitting mobile enemies in a static environment, which is the exact opposite of the situation here. However, they can be used as high damage alternatives to a ruby staff.
 * Bee Gun's high speed, homing, and bouncing (5 times) ability can be a very powerful weapon for this fight. You can increase their damage by using the Hive Pack if you're in Expert Mode.
 * If you have a Crimson world, you will want to bring a Crimson Rod and set up rain clouds periodically. The drops will pierce through the eyes and mouth, speeding up the battle greatly.
 * A tip for people that use meteor armor is use the Waterbolt until you run out of Mana, then switch to the Space Gun while mana regenerates.
 * The battle can be finished easily by building a bridge, using a Waterbolt and Diamond Staff (Or Ruby Staff), and wear a Magic Hat or a Wizard Hat (Choose a Wizard Hat if you want a little more damage to the WoF) and wear a Diamond Robe to increase your mana quickly. With a Wizard Hat, you can do just 10% more Crit. Strike change (note Magic Hat also increases your critical strike chance and damage by 6%, however, but the Magic Hat has 10% Crit and 15% Magic Damage).A Medusa Head can be Very Useful with the hungry and he can hit the 2 eyes and the mouth in one hit

Throwable Weapons

 * Spiky Balls are a good way to start the fight. If you are going to use ranged weapons throughout the entire fight these can help you kill some of the Hungries quickly and dealing some additional damage to the WoF.
 * Molotov Cocktails can be used to kill some of the Hungries. The fire left behind after the Molotov Cocktail has hit will do some extra damage to the WoF. These are recommended if you are not very accurate with your explosive throwing skills(100-150 to kill the WoF).
 * Beenades are a powerful weapon against the WoF and minions alike, and the bees' homing ability is invaluable.
 * Explosives, such as Grenades, may work as well, quickly clearing the Hungries. Even Bombs can be used. Although the timing may require some practicing it is not a great deal if the area is damaged, as you won't return to there till the fight is over. Perhaps the better option of explosives are Beenades. By the time you are prepared to fight the Wall of Flesh farming them from the Queen Bee should be trivial.

Accessories
Without full arena preparations, an Obsidian Shield is recommended for not taking damage from Hellstone. Furthermore, Spectre Boots or Lightning Boots, and a Cloud in a Balloon or the Sandstorm in a Bottle will help you maneuver around easier, while also helping you evade the lasers shot by the WoF. Other good Accessories are the Feral Claws for melee users and a Band of Regeneration for all users. In addition, a Lava Charm or Lava Waders can be useful as an alternative to Obsidian Skin Potion. If you have one and have either a bad aim or a relatively small amount of ammo, the Ammo Box should be activated before the fight, and it usually will last the whole fight and provide a chance not to consume ammo.

Reforging your accessories for more defense or damage will help with this fight. Reforging for movement speed will help later on in the battle, but Spectre Boots usually would outrun the WoF.

Potions

 * As always, at least 20 Healing Potions and 2 stacks of lesser healing potions will greatly help you survive.
 * Ironskin Potions will give the much needed defense boost. Each point of defense is more valuable than the last; the effects of this potion will be quite noticeable to most players.
 * Regeneration Potion is another useful survivability boost, and also Heartreach Potion can be useful if you are close enough to the hearts. Although the Heartreach Potion can only be crafted with worlds with The Crimson, it can also be found by destroying pots in The Underworld.
 * Swiftness Potion This is extremely useful to keep outrunning the WoF, especially once it's low on health and moving far faster than normal.
 * Obsidian Skin Potion and Water Walking Potion are good if you have no full arena preparations or if you meet the end of your arena.
 * Also using Gravitation Potion and Featherfall Potion will help you if you have no full arena preparations.
 * Magic users should also bring sufficient Mana Potions and consider using Magic Power Potions and Mana Regeneration Potions.
 * Shine Potions, Night Owl Potions and Hunter Potion can help as well, even though there is some light already.
 * A Bowl of Soup, Cooked Marshmallow, or Pumpkin Pie will give you a small buff in most stats.
 * An Inferno Potion will help a lot, as it can quickly get rid of the hungry, and hit the WoF itself when you are in close range.
 * It would be a good idea to bring restoration potions since they heal mana and health. Recommended regular restoration potions.
 * Gun users should bring an Ammo Reservation Potion this will give you your greatest chance not of run out of bullets during the fight.
 * A Calming Potion works well too, as the player will be able to mainly focus on the WoF most of the fight.

Threat Analysis

 * The Wall of Flesh has two large eyes. They shoot lasers at you, so it is good idea to be as far away from them as possible.
 * The two eyes share health. Defeat these to defeat the boss.
 * The eye lasers do not penetrate blocks, so a land bridge effectively eliminates half of the lasers.
 * There is also a mouth, which will deal heavy damage to you if you get too close.
 * It has a slightly higher defense value (0 for the eyes and 15 for the mouth respectively), so you may favor attacking the eyes instead.
 * There are many small creatures in front of it called the Hungry, held to the Wall by long tendrils.
 * If you kill them, they disconnect with one third health and will fly toward you.
 * The Hungries can block you from being able to attack the Wall until they are killed.
 * As you whittle down the Wall's health, the tendrils on any still-attached Hungry can reach out further, making it easier for them to reach you as well as interfere with ranged attacks.
 * The Wall's travel speed will increase as its health is diminished, allowing it to catch up faster/forcing the player to retreat quicker.
 * As the Wall loses health, its lasers will start to shoot faster and more frequently, so it may be harder to dodge them.
 * The Wall of Flesh's lasers will increase in damage the more it's health drops.
 * The Wall's mouth will spit leeches, which can damage you, but will also always drop a heart, making them useful to kill when you're low on health, but it is good to kill them almost immediately by aiming a ranged weapon at the mouth, as the leeches are one of the main sources of the Wall's damage.
 * The leeches released from the WoF use the basic worm AI, which means they can move through blocks. It is best to remain out of their reach, as they can be killed by swinging a melee weapon when they emerge from the ground.
 * Building a long stretch of wooden platforms high above the ground can considerably slow down the leeches, as they will not have enough area to tunnel in.

Strategy
The Wall will steadily move toward you, so keep your distance and plan ahead. If you get behind the Wall, it will pull you in front of it. You will be a little bit disoriented and possibly heavily damaged, so staying in front of it is absolutely a top priority. On the other hand if you move too far away from the Wall it will also pull you back. Be cautious, as this can sometimes fling you into hazards such as Lava, which will usually easily kill a player without Lava Waders or a Lava Charm. A Lava Charm can be found in a Gold Chest.

At the start of the fight you should focus on killing the Hungry, preferably using a melee weapon or piercing/exploding weapons. When the little creatures have been mostly eradicated, you can now focus on the eyes and mouth. Ranged players should, from about this point, take very little damage for the rest of the fight. Melee players, in contrast, may take hits from newly spawned Hungry and the occasional direct hit from the Wall, but will start to deal massive damage if they have a spear or flail. Dodging the eye lasers is easy. Jumping up and down when the lasers are shooting should help you avoid most of them.

After defeating the boss, the loot will be enclosed suspended in a box, so that lava is not a problem. However your world will enter hardmode if it isn't in hardmode yet.

Aftermath
After defeating the Wall of Flesh, you will have access to stronger weapons, Emblems, and stronger armor, making the fight a lot easier when you come back to it. Furthermore, if after killing the WoF you can immediately summon him again (of course waiting for the Guide to respawn!) This can be a great source of income, as Guide Voodoo Dolls are relatively easy to obtain.
