The Discipline of Spiritus opens the vampire up to worlds and vistas — and methods of feeding — that most Kindred can never touch. Vampires are spiritually dead, unable to create life. The shamanic ritual that created the Ahrimanes, though, allowed a spiritual connection between the undead and the vast, living world all around them. While the vampire can barely scratch the surface of what living shamans can accomplish, the Discipline of Spiritus is still formidable.
