Demonite Ore

Demonite Ore drops from Eye of Cthulhu and Eater of Worlds and can be refined into Demonite Bars. Together with Shadow Scale, armor, weapons and tools can be made. The ore does not occur naturally in the world, however it can be placed by the player. It has the same glow as Cobalt Armor ( Cobalt Armor was replaced by Jungle Armor in 1.0.3 patch ) had and emits light when it glows.

It sells for 8 silver.

Should not be confused with Ebonstone Blocks, as they look very similar.
