"The finest weapon ever made by Dwarf smiths, it is called Ghal Maraz or Skull Splitter, and was awarded to the founder of the Empire. Ever since it has been possessed by his inheritors or chosen champions."
(If on the board, Barbarian or Dwarf must take the hammer of sigmar when found)
The Hammer of Sigmar allows you to roll five Combat dice in attack.
Notes: Simply put, the Hammer of Sigmar is the most potent weapon in HeroQuest, using all the combat dice for every attack.
