Eater of Worlds

The Eater of Worlds is one of eight boss enemies. It is a giant Corruption-themed worm (resembling a Devourer, but much larger). It is summoned using the Worm Food from within The Corruption, or by destroying 3 Shadow Orbs.

The Eater of Worlds is not a single target, but a string of 50 body segments with individual life counters. When any inner segment is destroyed, it splits into multiple smaller worms, each with their own head and tail. Each section of the Worm must be killed in order to defeat the entire boss.

Fighting the Eater of Worlds is the only way to obtain Shadow Scale, which are required to craft the Nightmare Pickaxe, The Breaker, and Shadow Armor. Defeating the Eater of Worlds also produces usable quantities of Demonite Ore. Individual segments drop some of these when killed, with a larger bonus drop upon defeating the entire entity.

Tips

 * Farming the Eater of Worlds is one of the most effective ways of making money prior to Hardmode. Mid- to end-game armor and weapons will make the fight easy, and selling its drops will yield 9 to 11 each time, on average.
 * Weapons that pierce for multiple hits are effective, due to the Eater's large size (eg. Demon Scythe, Flails, Spears, Spiky Balls, Vilethorn). The Harpoon is also effective, and is best used when being charged by his head.
 * When you kill a section of the Eater of Worlds, they will drop hearts if the player is injured, as if it was another enemy. The near-constant hearts will heal the player, making the battle not as challenging as you may think.

Strategies

 * Increase your defense as much as you can, then craft a Grappling Hook. (Three iron chains, hook from piranha or skeleton.) Summon the Eater of Worlds and grapple onto the ground. Swing a close-range melee weapon. The grapple will prevent you from falling down chasms and the Eater of Worlds doesn't do very much damage, so this strategy works very well.
