Demon Altar



Demon Altars are used to create items that summon bosses, for example, Suspicious Looking Eye (Spawns Eye of Cthulhu) and Worm Bait (Spawns Eater of Worlds).

They are found at the bottom of chasms or near them in corrupted areas as well as in caves.

If you attempt to destroy it with a Hammer, the player will lose half of their current health. Demon altars are rare outside of corrupted areas.

It's possible for an altar to spawn in a cave outside a corruption zone. In extremely rare cases there can be two, or more, altars spawned in a cave, outside of a corruption zone.

In the paid version of Terraria, Demon Altars are commonly found Anywhere.

If you're trying to find an altar, remember that they generate a small, flickering amount of light and you might be able to catch a glimpse of one through a wall while in a cave or chasm.
