Diablerist (VTR)

From the White Wolf Wiki, the most complete White Wolf reference

A Kindred who commits diablerie. (VTR: Vampire: The Requiem Rulebook, p 158)

Diablerists generally perform such an act for one of two reasons - to gain in power by raising their Blood Potency or because they are addicted. The former tends to be more careful when choosing victims, as diablerie must be performed on vampires in torpor; nothing is as attractive to power-hungry neonates as the rumors of an elder in torpor. However, it is not unknown for a diablerist to beat their victim into torpor themselves before performing the act.

While the benefits of performing diablerie are many, among them increased Blood Potency and the chance of gaining new skill in disciplines, the drawbacks are considerable - the diablerist's Humanity automatically sinks, and black veins dot their aura for a number of years equal to the victim's Blood Potency, making them walking targets for Auspex users. Most are careful not to be seen.

Diablerie is addictive the same way that vitae is addictive, especially to elders (who usually must drink vampire blood just to survive). Diablerie-addicted elders are feared by many a vampire.
