Adamantine

An extremely hard metal found deep in the mountains of Varthea and Gullonde. When exposed to magical or natural light the metal gives off a dull green hue. This metal requires enormous heat and experience to forge into competent weapons and armor. Adamantine is fifty percent heavier than steel but far beyond it's strength. Armor and structures made from this metal are four times as strong and weapons made by it ignore other materials and metal's hardness as if it were as soft as wet clay. A hammer made of adamantine is quite the valuable tool to a smith, especially a dwarven one. An adamantine hammer can forge metals while much cooler than other tools. This allows for the creation of some of the finest tools and creations possible.
