Aush'Admar (Warhammer)

Aush'Admar was forged in the ancient fires of a long-forgotten anvil in the 223rd layer of the Abyss. Built for the Demon Wars, the weapon hungers for death and carnage. Unmistakable on the battlefield, Aush'Admar exudes clouds of hot black smoke and wisps of fire whenever it strikes demonic flesh.
When you hit a demon with this weapon, the demon takes an extra 3d6 damage.
