Obsidian Brick Wall is found in the Underworld in certain Underworld Houses and can be collected with a hammer. Obsidian Brick Wall has a black coloring with red spots. It is the only wall type that requires a furnace to be crafted. Another oddity is the player placed version looks different from the version that can be collected from Underworld Houses.
- The look of Obsidian Brick has changed
- Increased max stack to 999
- Fixed bug where mining the wall would produce Obsidian.
- Added to the game.
