Adamant

Adamant is a rare metal found only in the Hades dimension. Adamant ore is more abundant in the Elysium region, and even so on the island of the blessed. Like all metals, adamant can be fashioned into tools and its own block, but unlike other metals, its ore can not be refined in a furnace, and requires the enchanter to refine it into ingots

Adamant tools have relatively the same attributes as iron tools, although with the same harvest level as diamond. However, the durability of Adamant tool is massive, nearly three times as much as netherite. Also, adamant blocks have a massive hardness and blast resistance, 250% as much as obsidian.
