Acidstone

Acidstone is a block type found in The Corrosion. Before Hardmode, it is more prominent in the lining of Corrosion chasms. It requires at least a Fleshbreaker Pickaxe or explosives to mine.

It is the Corrosion equivalent to stone, similar to the Corruption's Ebonstone, Crimson's Crimstone, etc. It can become converted to ordinary stone with Purification Powder.

In Hardmode, it can spread the Corrosion and can also create more Acidstone.
