In the World of Darkness roleplaying games published by White Wolf Games Studio, diablerie is a process by which one vampire can consume and acquire the supernatural power of another. This is usually accomplished by putting fang to throat and sucking away all of the other vampire's blood, thus symbolically and literally consuming the other vampire's damned soul. Diablerie can have unpleasant consequences, such as Humanity loss (that's why the Elders gave us Paths of Enlightenment!) and soul-shards. It is rumored that the vampires of the Tremere clan have developed thaumaturgical rituals which allow them to share in diablerie... rumors which the Tremere, of course, deny emphatically.
