Demonite Bars are the refined form of Demonite Ore, requiring 4 ore per bar. A Furnace is required to craft Demonite Bars. Demonite is the ninth tier in the twelve tiers of pre-hardmode Ores: one tier above Platinum, but one tier lower than Crimtane Bar. It is the counterpart of Crimtane on worlds where the Crimson is replaced by the Corruption.
Any item made with Demonite Bars will emit a small amount of shadow particles.
110 Demonite Bars (or 440 Demonite Ore) are required to craft all of the Demonite tier items along with an additional 56 Shadow Scales.
Any Items created with Demonite Bars are worth as much or less than a single bar. To gain money faster it is wise to defeat the Eater of Worlds or the Eye of Cthulhu and sell the raw ore.
Demonite does not change value when made into bars. This makes it much quicker to sell a stack of ore than crafting them into bars first, because it will yield in exactly the same amount of money.
Demonite can be easily found around the corruption in groups of 2-5.
Items made out of Demonite are faster than their Crimtane counterparts, but deal less damage per hit.
