Learn how to summon and defeat the Wall of Flesh in Terraria. Discover its stats, weaknesses, and the powerful loot it drops, including emblems and unique weapons.

The Underworld is a dangerous biome filled with valuable resources like Hellstone and Obsidian. You'll need Obsidian Blocks and a Hellforge to craft Hellstone Bars. Be cautious of structures made of Hellstone Bricks, as they inflict Burning damage unless you have an Obsidian Skull or its upgrades. Shadow Chests found in the Underworld can contain powerful items, most notably the Hellwing Bow, which is highly effective against the Wall of Flesh.

Wall of Flesh Boss

The Wall of Flesh does not spawn naturally; it must be summoned by throwing a Guide Voodoo Doll, dropped by Voodoo Demons, into lava. This action will kill the Guide NPC, so it can only be done once per in-game day.

Stats / Weaknesses

  • Mouth Part: HP 8000/11,200, Damage 50/150, Defense 12/18
  • Eye Parts: HP 8000/11,200, Damage 22-30/44-60, Defense 0/6
  • The Hungry 1: HP 240/366, Damage 30-75/60-150, Defense 10-40/16-40
  • The Hungry 2: HP 80/112, Damage 30/60, Defense 6/6

Note: The Hungry 1's damage and defense stats change based on the Wall of Flesh's remaining HP (100-76%, 75-50%, 49-25%, 24-1%). The Hungry 1 are attached by strings and transform into Hungry 2 when damaged sufficiently.

Phases

  1. When the Wall of Flesh spawns, you will be inflicted with the Horror debuff, preventing teleportation out of the Underworld. Attempting to do so results in instant death.
  2. While in the Underworld, leaving the biome or moving too far from the Wall of Flesh inflicts the The Tongue debuff. A tendril will attach to you, pulling you towards the mouth and dealing 50 damage per second.
  3. The Wall of Flesh increases in speed at 75%, 50%, 25%, and 10% of its health. In Expert Mode, additional speed increases occur at 66%, 33%, 5%, 3.5%, and 2.5% HP, reaching speeds that may require minecart tracks for evasion.

Strategy

  • Run away from the Wall of Flesh on a long runway and attack its eye, which has the lowest defense. If the eye is obstructed, target the mouth parts.
  • Destroy the Hungries to allow damage to the eye and mouth. They drop hearts that can aid in survival.
  • The eye fires lasers, and the mouth spawns Leech enemies that also drop hearts.
  • In Expert Mode, Hungries and Leeches drop hearts less frequently, making regeneration and potions more crucial. Hungries respawn, so piercing weapons are beneficial.
