Acridium is a rare, nigh-impossible to mine metal found on Dis. The strange mineral's surface is a silverish color, though it glows a bright blue-green that is enough to illuminate areas where it is found.
Acridium's special trait is that it is strangely corrosive to any surface it touches being able to erode through soft surfaces like clothing or flesh quickly, and even thick metals over time. How this occurs is still unknown, though many believe it is created through solid mana reacting to another metal over long periods of time. Acridium is only able to be smithed with tools of thanatite or or obsidian, and even then it is a difficult material to work with.
