It's a Demon Altar. After killing WoF (Wall Of Flesh), you can break these with the

Pwnhammer, and when you break it the Demon Altar will dissapear and the first

one you break will spawn Cobalt, breaking another one spawns Mythril, breaking a 3rd one

spawns Adamantite. 4th break spawn less Cobalt, and so on.

'''Note: The Wall might not drop a Pwnhammer. You will have to kill him again to get it.'''
