Demon Altar

The  is a crafting station that can be found in Chasms in the Corruption, Underground, and exceedingly rare in water above ground or in Dungeons. They are the counterpart to Crimson Altars.

The Demon Altar is used to create the following items:
 * Slime Crown
 * Suspicious Looking Eye
 * Worm Food
 * Night's Edge
 * Abeemination



As of v1.1 it is possible to destroy these Altars with the Pwnhammer dropped from the Wall of Flesh. Destroying them "blesses" your world with one of the three new ores in two possible groups: Cobalt Ore, Mythril Ore, or Adamantite Ore in the first group. and Palladium Ore, Orichalcum Ore, or Titanium Ore in the second group, (each ore rotating in that order). Blessing your world turns any type of block that is usually generated with pre-Hardmode ore (from the Underground or below) into the new ores and places one Pearlstone Block and Ebonstone Block randomly in the stone layer (this means that if you built a dirt/stone path to fight the Wall of Flesh, ore could spawn in it). By destroying more Altars, your world will get more of the new ores, but every 4th Altar spawns fewer ores than before.

The only way to destroy a Demon Altar is to use a Pwnhammer or stronger within a Hardmode world. Attempting to destroy a Demon Altar with a weaker Hammer than the Pwnhammer or in a pre-Hardmode world will deal damage approximately equal to half of your current health (affected by armor) and leave the Altar unaffected.

Trivia

 * It appears that all Demon Altars spawn within a very thin window of depth, only several blocks tall. Digging a horizontal tunnel through the map, albeit very time-consuming especially in large worlds (8400*2*3 blocks without holes), would allow one to find every Altar.
 * In Alpha, Demon Altars were also used to make certain Armors.
 * If you try to break a Demon Altar while you're in pre-Hardmode or with a Molten Hamaxe or lower, you will get damaged as stated earlier, but if killed, the Death Message says only your name: .
 * It would appear that in 1.1 worlds, Demon Altars are spawned in amounts divisible by 3.
 * Sometimes, mostly in the Corruption (maybe only in the Corruption), a block may spawn stuck inside a Demon Altar (such as Demonite Ore or Ebonstone blocks). If this Altar is hit with a Hammer, it will disappear, the world will not be blessed, and you will be hurt. This can also happen with Altars which are missing parts due to a graphical glitch.
 * Demon Altars are normally easier to find in the Corruption due to a possible increased spawn rate and vast caves. Multiple Altars can be found easily inside the Chasms. However, sometimes Demon Altars can (but rarely) be found elsewhere outside of the corruption biome.
 * When a world is blessed with any ore, it may even spawn in your screen.

Bugs

 * Will sometimes be invisible, or missing blocks of it, but can still be mined and will still give off a faint glow, even when invisible.
 * When using Purification Powder on a Demon Altar, even outside of Hardmode, the Demon Altar is destroyed.
 * Using the Ice Rod on a Demon Altar will destroy it. Breaking it this way will create new ore in the world.
 * Demon Altars may spawn in midair.
