Thirst of Caine
7 point Flaw
By age or some infirmity of your own blood, you derive no nourishment from the blood of animals or mortals. Though you do not immediately vomit such a meal, living blood tastes bland and provides no benefit. Only the vitae of other Cainites can sustain you. The sole advantage to such hunger is that you find no allure in human blood and thus no longer perceive humans as food. As such, the sight, scent or taste of human blood will never drive you into frenzy. If you are not extremely careful, however, your thirst will inevitably lead you to blood oaths and the forbidden draught of the Amaranth.
