Durum

Durum is a dark iron that seemingly only exists in the mountains of The Black Steel Hills. It is hard and cold to the touch and is extremely heavy. Many blacksmiths have tried to tame this metal, but only a few, outside the dwarves of the Black Steel Hills, have managed. To mold, this metal one needs to temper it with constant Dragonfire. The process is both dangerous and expensive, but when done right can be extremely fruitful. A single Durum dagger can be worth up to ten thousand gold. It will never go dull and will slice through flesh like its nothing.
Durum armor gives a +3 to AC, it is not magical and can be affected by spells. Due to the nature of the metal, it does not require maintenance unless affected by a Dragonfire for a minute.
