Lava Walls

Lava Walls are naturally-generating background walls found in the Cavern layer at a depth where lava replaces water. These naturally occurring walls can be destroyed with a hammer, but will drop nothing. These walls also do not stop enemies from spawning and cannot be used for proper housing.

On the versions, the Obsidian Wall is the only Lava Wall that will generate due to it being the only one that exists in those versions.

On the, these walls can be made from Hellstone (or in the Obsidian Wall's case, Obsidian) where they can all be used like other craftable walls.
