Acidine Ore

Acidine Ore is a pre-Hardmode Ore. It is the Corrosion counterpart to The Corruption's Demonite and The Crimson's Crimtane Ores. It will only appear naturally in Corrosion worlds in small veins Underground, however, only usable quantities will come from bosses, namely Stomach of Cthulhu and Eye of Cthulhu (in Corrosion worlds). Acidine Ore emits a faint yellow glow when placed.

Like Demonite and Crimtane Ore, the pickaxe power required to mine Acidine Ore changes with location. Below ground level, a Gold Pickaxe or better is needed, while above ground, any pickaxe will do. Alternatively, any form of tile-destroying explosives, such as Bombs can be used.

Acidine can be crafted into Acidine Bar, which are then used in the creation of Corrosive Armor and its corresponding tools.

Trivia

 * Acidine Ore does not spread the Crimson. This rule applies both to the pre-hardmode and hardmode stages.
 * Acidine Ore, and its counterparts Demonite Ore and Crimtane Ore, can be mined extremely early-game with bombs, though because they are both very rare this is not a very viable method to gather any appreciable amount.
