Guide:Wall of Flesh strategies

"The master and core of the world..."

The Wall of Flesh is the final Pre-Hardmode boss. It is composed of two eyes which will blast the player with lasers, and a mouth in between. Defeating it is required to enter Hardmode.

Summoning
To summon the Wall of Flesh, you must throw the in the lava in The Underworld while the Guide is alive. Alternatively in expert/master mode, you can put the Guide's house in The Underworld, shut the door, and kill a Lava Slime. It will kill the Guide with the lava and summon the boss.

Its sweep direction is determined by its spawn location. Summoning 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 into lava from. 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.

The Fight
The Wall will steadily move toward you, so keep your distance and run. 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 items that give immunity to lava, e.g. a or an obsidian skin potion.

At the start of the fight you should focus on killing, preferably using piercing weapons or Explosives. When they get killed however, they detach, meaning that they will come to you. Kill them as fast as possible, while trying to damage the rest of the swarm.

When the Hungry have been mostly eradicated, you can now focus on the Eyes and Mouth. They share health, and the Eyes don't have defense. Prioritize Eyes over Mouth.

Close-ranged players may take hits from newly spawned Hungry in expert/master and the occasional direct hit from the Wall. Dodging the Eye lasers is easy: Jump up and down when the lasers are shooting, you'll avoid most of them. Just remember that the lasers come from both Eyes.

Be careful though, as you will have to deal with the. As they're worms, they need solid blocks in order to navigate around. Be mindful of the terrain (and bridge), and use your penetrating or melee weapons against these. They drop helpful heart pickups, so make sure to take them.

As the Wall takes more damage, it goes faster. And it increases the fire rate and damage of the lasers. Keep dodging, and make sure to never stop running, even once.

The Horrified debuff has the effect of instantly killing you when you use your or. It does so after you return to spawn, allowing you to recover your money (and items on Mediumcore) instantly. Do that if you ran out of space to defeat it. However, it's not useful on hardcore difficulty.

Expert Mode
The already hard-to-obtain hearts are now more rare: Leeches have a 20% chance of dropping at least one, meaning that you get healed from the boss less often.

Not only does the Wall of Flesh have more health, but it's also faster. At low health, it'll almost outrun you, while lasers can reach Retinazer-esque fire rate. You can minimize the chance of getting caught by making the last stretch more open beforehand.

The Hungry will respawn over time, making non-penetrating ammo less effective against the Wall.

Master Mode
In addition to the health and damage boost the Wall of Flesh recieves, instead of flinging forward the player when in contact with the wall, it will instantly kill the player.

Terrain preparation
The Wall of Flesh benefits from having an arena prepared more than other bosses.

The simplest arena is a long bridge of about 750 blocks with some space above it for the player to maneuver. Placing the player out of danger from falling into lava and ensuring that they can keep a steady pace of progression allows the fight to go quickly and smoothly. Players may also wish to place lights and along the bridge; alternatively, Obsidian Platforms can be used, as they do not break when contacting lava, and the materials to make them can be obtained in bulk by demolishing the Ruined Houses.

However, one can skip the whole terrain preparation process by consuming Water Walking Potions or wearing Lava Waders instead. In 1.4 the Terraspark Boots may be preferable.

Note that Underworld map generation tends to place Ruined Houses towards the middle third of the map, leaving the eastern and western wings mostly clean.

The Wall of Flesh begins its attack from whichever side of the Underworld's map edge you're closest to. This allows you to control its direction of approach. Fight in the direction you're most comfortable with.

Killing the Wall of Flesh will generate a bricked-in treasure box above your bridge. The bricks can serve as kill-markers, but they may interfere with movement if your next fight runs close to that spot.

Alternatively, you can build the arena with, because you can keep a safe distance with a with decent speed.

Gearing up
Having 400 health is pretty much required at this point, especially since Hardmode will start immediately after the Wall's defeat.

Armor
Molten Armor has the highest defense and melee damage bonuses. If the fight is done with a Sword or a Spear, Shadow armor with its extra melee speed can prove to be useful as well.

Crimson armor provides a very noticeable boost to life regeneration and a small amount of extra damage. For a defensive build, this is the most efficient option.

The Necro armor is the best pure set for a Ranger. If a Gi is available, it can be replaced for the Necro Breastplate to get more offensive bonuses in exchange for its set bonus, which has no effect in combat as it only affects ammo consumption. The Wizard set, consisting of a Wizard hat is the strongest magic set available. Jungle and Meteor armor have weaker bonuses but they can also be efficient choices.

A summoner's only choice is the Bee armor.

Weapons
For Melee users: Due to Melee's relatively short range, this fight can prove to be extremely difficult, however players can make the fight much easier by simply running away, turning the tussle into a trivial trifle.


 * The has autoswing and doesn't turn the player around in the direction they are facing, making it the most efficient sword for the fight. Since it attacks in an arc,  it can hurt the Wall of Flesh and keep the Hungries away in the same swing, unless they come from below.
 * The can be use to maximize bee damage against the Hungry and the Wall of Flesh, as the bees can also damage the Wall of Flesh itself. The downside is the lack of space between the player and the hungry, so a high defense is needed.
 * The has stronger DPS than the sword above, however it's incredibly inefficient against the Hungries due to its small hitbox, making it more efficient near the end of the fight.
 * The has much more range than a close range sword, especially with a String. However, due to the nature of Yoyos it is easy to get overwhelmed by the Hungries if not playing carefully.
 * The may be used to damage both the Wall and Hungries if your arena is low enough (and sufficiently far from the Underworld ceiling) so that its stars don't get stuck.
 * The pierces with medium range, making it effective at both the hungry and the wall, and on  can prevent the hungry from touching you at all with 1.4's new flail mechanics.

For Ranged users:


 * The Hellstone ranged weapons, and, do a very efficient job when used with  and  respectively.
 * The is the strongest bow due to its rapid fire and piercing projectiles. Since it only requires Wooden Arrows to shoot its bats, ammunition for it will be pretty easy to obtain.  has similar properties but is overall weaker.
 * While it's hard to get ammo for it, the is an extremely efficient weapon to use due to its great stats and piercing. It can kill the Wall of Flesh in mere seconds.

For Magic users:
 * The is one of the strongest weapons against the Wall, as its projectiles can hit the Wall and the Hungries multiple times per hit.
 * is also extremely efficient, being able to hit all 3 body parts in one cast if shot into the ceiling to make it ricochet.
 * is great choice because of it's ×10 damage attack. With some real luck, a 300 tile long hellbridge is enough for master mode!

For Summoners:
 * The is the strongest minion available.
 * Of the sentry weapons sold by the Tavernkeep, the best options are the and the . The Ballista Rod has incredibly high damage and their bolts are capable of piercing, while the Explosive Trap Rod inflicts damage in an area of effect. While the sentries themselves are slow to attack, you can continually re-summon them to make them immediately attack, significantly reducing the cooldown time.
 * The can be used to attack any Hungry that gets too close. However, this will cause your summons to switch to attacking the Hungries instead of the Wall of Flesh.

For Throwing users:
 * can be used to kill some of the Hungry. The fire left behind by the Molotov Cocktail will do some extra damage to the Wall. These are recommended if you are not very accurate with your explosive throwing skills(100-150 to kill the WoF).
 * The is arguably the most effective weapon against the Wall of Flesh of any class. They deal consistent and rapid damage to all of the boss's parts, including The Hungry, and can do so from a great distance.
 * Explosives, such as the, may work as well, quickly clearing the Hungry. Even can be used to great effect, although the timing may require some practice. The drawback is that using explosives this way will cause major environmental damage.
 * Although expensive, is a great option. They deal extreme area of effect damage, capable of quickly killing The Hungry and hitting multiple parts of the Wall itself.

Accessories

 * Variants of the Lightning Boots and Cloud in a Bottle will help you maneuver around easier to evade the lasers shot by the Wall.
 * Lava Waders or Terraspark Boots allow you to walk on the surface of the underworld's many lava lakes unharmed, which is necessary without a hellbridge.
 * The only true offensive accessory in Pre Hardmode is the Shark Tooth Necklace and its upgrade, the Stinger Necklace, which increases damage dealt by 2-3 points, and the stinger necklace also releases bees when you're hit. Melee users have Feral Claws, but their help will only be noticeable when using a Sword or Spear.
 * The expert exclusive Worm Scarf and Shield of Cthulhu help greatly with survivability and mobility respectively.
 * An Obsidian Shield is mandatory if doing the fight with a close ranged melee weapon, as knockback is a great issue when standing close to the Wall.
 * The Brain of Confusion can prove useful if you are low on HP.

As always, make sure to have your accessories reforged to Warding, Menacing or Lucky to get the most out of each slot.

Potions

 * Ironskin, Endurance and Regeneration Potions do wonders for survivability. If obtained from a Shadow Chest or an Underworld Pot, the Lifeforce Potion can also be used to great effect.
 * The Heartreach Potion is invaluable for collecting the hearts dropped by the Hungries.
 * The Inferno Potion can help deal extra damage to the hungry and leeches, both of which are vulnerable to On Fire!, and takes care of any stray Fire Imp projectiles
 * An Archery Potion is extremely useful when using a Bow.
 * The Ale or Sake give significant Melee bonuses with a very insignificant downside.
 * The Magic Power and Mana Regeneration potions should always be used when doing the fight with Magic weapons.
 * A Wrath Potion or Rage Potion increase overall damage against the Wall.
 * The Titan Potion has an use for keeping the Hungries away, especially when Melee weapons are being used.
 * Swiftness Potion helps a bit with mobility.
 * 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.
 * A food item such as Cooked Fish, a Bowl of Soup, or Pumpkin Pie will give you a small buff in most stats.
 * A Calming Potion works well too, as the player will be able to mainly focus on the Wall most of the fight.
 * If you have defeated Turkor the Ungrateful, using the Horn o' plenty should work well if you don't have many healing potions.

Boulders Head-start
If you can jump, 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.

Mouth-only Tunnel Strategy
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 very good at dodging the WoF's Lasers and the Hungry.

Autofarm Strategy with Boulder Statues


One more strategy could be to set up an farm that can kill the Wall of Flesh without the player even being in the Underworld. This strategy involves killing the Guide in Lava so that Wall of Flesh spawns, and then killing it with Boulder Statues.

To do this, you must make a house for the Guide in the Underworld at the edge of the world and set up Timers that actuate blocks to make him fall in the lava at least every 20 seconds. Put Lava beneath the blocks that are actuated and make sure that there is always a floor so that the Guide will never spawn somewhere else. Place a Pressure Plate in Lava to detect when the Guide falls in it. You should also put some other kind of trap to be sure that the Guide dies quickly in Lava, as it could take a while if he has a lot of Defense.

After setting up the Guide's house, you just have to set up the Boulder Statues. The Wall of Flesh speeds up when it's damaged, so place Boulder Statues with space between them varying: 10 with a space of 2, 5 with a space of 4 and 10 with a space of 6. This should beat it every time in Classic Mode. The Wall of Flesh will be killed endlessly, and you can let this farm run while continuing to play, gathering the drops as you see fit.

Aftermath
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 has yet to enter it.

After defeating the Wall of Flesh, you will have access to stronger Weapons and Emblems, making the fight a lot easier when you come back to it. Furthermore, 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 or loot.
