Hephasto the Armorer
From Diablo Wiki
Hephasto the Armorer is the Head Armorer of the Burning Hells. Hephasto is identical in appearance to The Smith, but is tougher and stronger than his subordinate. Hephasto guards the Hellforge in the River of Flame. He drops the Hellforge Hammer, which is required to destroy Mephisto's Soulstone, after he is slain.
[edit] Background
When the Seraphim who followed the Angel Inarius into battle were made to pay for the destruction of an infernal temple by an outraged Mephisto, many were forced into unholy servitude to the Lord of Hatred. Inarius himself was bound with tremendous chains as the wings were slowly torn from his back. Great barbed hooks were then used to stretch out his once glowing skin and his features were distorted by the vile powers of The Three.
Hephasto, one of the weapon-smiths of Inarius that was corrupted by Mephisto, rose through the ranks of Hell to become a master armorer for the forces of darkness. While his place at the fires of the Hellforge is coveted amongst jealous Overlords, none dare cross swords with him lest he take the anguish of his lost glory out upon their bloated bodies.
[edit] Tips and Other Additional Information
Special Abilities:
Hephasto's Conviction aura is very dangerous, especially if you are fighting him around Abyss Knights. He is weakest against Poison so use poison attacks against him whenever possible.
