Blood Use
Vampire characters may spend blood to heal themselves. To do so, the character must concentrate and do nothing else for one full turn. A character may attempt to heal while performing other actions, but this requires success on a Stamina + Survival reflexive roll (difficulty 8). Failing this roll means the vampire loses all expended blood points with no effect, while a botch causes the vampire to lose both an additional blood point and an additional health level. Spending blood to raise Physical Attributes or power Disciplines may be done automatically, without the need for concentration. A character may spend an amount of vitae equal to her per-turn rating, as dictated by her Generation (p. 270 -- VTM 20th Edition).
