Obsidian Brick Wall

Obsidian Brick Wall is a type of wall commonly found in the Underworld as the wall of Ruined Houses. It can also be crafted from the bricks such houses are made of.

The Obsidian Brick Wall actually exists in two versions: natural and crafted. The natural version is the type found in Ruined Houses. When destroyed it drops the Obsidian Brick Wall item which the player can use to place the craftable type. As the player cannot remake the natural version, the Obsidian Brick Wall is partially an unobtainable wall type.
