Hallowed Bar

Hallowed bars are ingots used to craft high-end armor/weapons in the game. They are dropped by the Hardmode bosses, namely The Twins, The Destroyer, and Skeletron Prime. This can make them rather hard to obtain or farm.

Before 1.2, crafting Hallowed Armor and gear required Souls, as well as the Cobalt, Mythril, and Adamantite versions of the item in question. With the release of 1.2, crafting Armor and weapons such as Excalibur has become exponentially easier.
