Soul Scavenger, Heart of Stone is a unique Primordial Scavenger in Act V of Diablo III. It appears as the "boss" of the Demon Souls event which takes place in Pandemonium Fortress Level 1.

Jamella reveals that Soul Scavenger comes whenever a Soul Crucible is full, draining its contents and "channeling the souls to Malthael".

In combat, it has Reflects Damage and Orbiter traits.

Visually, Soul Scavenger has a different and unique coloring. It is also the only Primordial Scavenger that can be found outside the Battlefields of Eternity, and the only one clearly working for Malthael.
