* '''Location:''' Hellforge in the River of Flame
* '''Reward:''' Smashing Mephisto's Soul Stone on the Hellforge drops four random type gems, one normal, two flawless, one perfect per player finishing the quest. The Expansion adds one dropped Rune per game. The rune is randomly selected from within the following ranges:
* * '''Normal: ''' El (r01) - Amn (r11).* *''' Nightmare: ''' Sol (r12) - Um (r22).* * '''Hell: '''Hel (r15) - Gul (r25).
* '''Quest Priority:''' Optional quest, but a good reward. It was frequently skipped in v1.08 and earlier since Hephasto was so fierce. In D2X it's much easier and has a better quest reward.
