Massacre Steel

Massacre steel is an immensely rare and potently magical metal forged from the iron found within the blood of humanoids. Due to the sheer number of bodies required in creating even a single ingot, which is minimally in the hundreds, massacre steel is widely considered an abomination. Despite this, some of history's most wicked have sought to create items forged from massacre steel. It is unknown how many such items have been created.   Items forged of massacre steel are practically indestrictible. After forging, the item is quenched in the blood of its maker. After this point, no method, including divine aid, has been found that can damage the item.
