Maul used by Dwarven Hero who is said to be the son of Moradin. He is said to have invented Mithril, created a mine to the center of the planet, and fantastically slayed all manner of beasts. The Maul is all black with a skull embossed into the head. The eyes of the skull bleed in Combat.
The Maul wants to be wielded by a true Dwarven hero, and therefore is looking for a hero who can attack with a flurry of blows. It seems likely that more than 1 attack a second would make the Maul believe that the wielder was sufficiently powerful.
