Diablerie is the heinous act of consuming a fellow vampire completely, down to the victim's very soul. The act of diablerie can increase a character's Blood Potency and grant them access to powers and Disciplines known to the victim, but at a terrible cost to the character's Humanity. Diablerie leaves characteristic black veins on the aura of a Kindred observed through the Auspex Discipline. A Kindred who commits diablerie is called as diablerist.
