A Demon Altar is a crafting station found randomely underground, or near the corruption. They are used to craft items like the Suspicious Looking Eye, Worm Food, Night's Edge, and other items. Once you enter hardmode (by defeating the Wall of Flesh), you can destroy these with a Pwnhammer, or the Hamdrax. If you hit it before hardmode with the Pwnhammer or Hamdrax, you take damage. If you hit it with any hammer other than the Pwnhammer or Hamdrax, regardless of hardmode being activated, you will take damage. Hope this helps!
