Shadow Orbs

Shadow Orbs are purple floating orbs located at the bottom of Chasms found in The Corruption. They're typically protected by a few layers of Ebonstone, so using a Nightmare Pickaxe (or better), Dynamite or Purification Powder is a must if you are to destroy them. Once you reach the orb, you can break it with a Hammer or Dynamite.

When you break a Shadow Orb, depending on how many you've broken before, you'll either get a message or summon a boss. The first message reads "A chill runs down your spine...", whilst the second message will read "Screams echo around you...", implying that destroying the Shadow Orbs will cause something terrible to happen. If you break your third Shadow Orb, you will awaken the Eater of Worlds.

When a Shadow Orb is destroyed, the player will get random loot which includes, but is not limited to, guns, staves and magical orbs.
