Finally, the act of Amaranth stains the diablerist’s own soul upon its commission. The character’s aura acquires black veins that reveal her crime to those who can scrutinize such things (see p. 120). These black veins remain in the diablerist’s aura for one year per dot of Blood Potency the victim possessed. This time is cumulative; a vampire who diablerizes two Kindred of Blood Potency 6 has veins in his aura for 12 years. If a character diablerizes his victims years apart, the additional years add on to the end of last. For example, if a Kindred diablerizes a vampire of Blood Potency 4 and two year later diablerizes a vampire of Blood Potency 5, the black veins appear in her aura for seven years following the second diablerie — or longer, if she keeps to her wicked ways and diablerizes again.
