Demon Altar

Info
A Demon Altar is a special Crafting Area that is mainly used to create summoning items. Is is also used to make the Night's Edge. A Demon altar spawns in the Corruption, if your world is Crimson, then the crimson equivalent (Crimson Altar) will appear instead. Once you defeat The Wall Of Flesh, it is possible to break a Demon Altar using the Pwnhammer he drops. Doing this will cause your world to be 'blessed' with a certain Hardmode Ore. Attempting to break a Demon Altar before Hardmode will cause the player to lose a considerable amount of health.
