Chasms

A Chasm is a deep hole through Ebonstone, with Ebonstone Wall background, found in The Corruption.

Generally there is an underground tunnel which connects most of the Chasms in a given pre-generated Corruption area. At the bottom of most Chasms a Shadow Orb can be found behind a small wall of ebonstone. To reach the Shadow Orb, a player can either use a Nightmare Pickaxe, Molten Pickaxe, or any drill to mine the Ebonstone, drop Dynamite, or use Purification Powder to turn the Ebonstone into common Stone and mine it with any Pickaxe. There is also a good chance that players might bump into a Demon Altar when traversing these caverns; they dont have any relation to the chasms but they have a high spawn in the corruption and going down a big chasm gives you a good chance to spot one. Players should be careful while climbing Chasms and bring a Grappling Hook (or Ivy Whip) if you're going to climb out, though it is occasionally possible to jump out of a Chasm using the small ledges on the sides and a Cloud in a Bottle. Another tactic is to place easily found bricks such as Dirt or Stone on the walls of the chasm to create a crude staircase upwards, or to simply teleport back to your spawn using a Magic Mirror.

Chasms are often full of Eaters of Souls, which make searching for Shadow Orbs more difficult. Fighting the Eater of Worlds inside Chasms can be harder than on the surface, although less so in the tunnels linking the Chasms together.
