Wheel of Time - Mah'alleinir (U10).

A warhammer forged by Perrin's hand with the help of Asha'man and the Circle of the Sages. The hammer is forged by force, for the first time since the Trolloc Wars, forged by the strength and feelings of its creator. The hammer is warm to the touch and burns Shadowspawn upon impact, going so far as to be able to kill Darkhounds. Found in the "Blunt Weapons" section
