Kingslayer is the rune word 'MalUmGulFal' for swords or axes in Diablo II: Lord of Destruction. Kingslayer is a very powerful weapon in the hands of any physical fighter specializing in swords or axes, or a Barbarian Warrior. Unfortunately, it is also fairly expensive to make. It offers a reasonably high chance of Crushing Blow and Open Wounds, and the +1 to the Vengeance skill allows it to deal large amounts of elemental damage.
