The legendary smith Torkinal of Ur is said to have made five hammers (possibly six). Each hammer is of huge size, requiring a Physical of 16 just to wield, but nevertheless finely crafted. In the hands of a skilled weaponsmith (Mining / Armoury 6+) the Hammer may be used to forge an enchanted metal weapon, which has +2 Attack and +2 Damage compared to a normal weapon of the same type. The forging process requires three days of work in addition to whatever time is normally required to make the weapon, the extra time being used to work the blade with the Hammer. Each time a weapon is crafted in this way some of the Smith's essence is passed to the blade. The Smith loses one level of both Health and Physical.
After a certain number of uses (the exact number is not clearly recorded), or on any fumble while using it, the Hammer vanishes until found again.
