Archeon/Shadonium Bar

The Shadonium Bar is a Pre-Hardmode bar. It is used to craft various tools and weapons. It's crimson counterpart is Vyssonium.

The bar was at first was just normal ebonstone, but over time it was corrupted by the overwhelming inevitable evil that lurks in the shadow of the Corruption. The bar inside is almost fully rotten flesh, yet the durability and strenght of the bar is unnaturally high.

Some have said that it's unnatural abilities come from harnessing the inner darkness, that the bar maker has inside them, thus corrupting even the strongest of heroes who have risked making items out of it...
