Vitae Efficacy Unit

"Vitae Efficacy Units" or "VEUs" are units developed by the Tremere researcher Maxius and the Malkavian Dr. Douglas Netchurch in order to measure the efficiency of a vampire's vitae (the game mechanic of the blood pool). The research lead to the conclusion that Kindred of lower generation have more VEUs to expend and that the thin-blooded have to expend more VEUs in order to activate the "natural" abilities of a vampire.

There are five scales that are currently used:

• The Starvation Scale, which measures the amount of blood the vampire needs to substain himself before going into torpor.

• The Ghoul Scale, which measures the potency of the blood needed in order to create ghouls.

• The Wound Regeneration Scale, which measures the amount of blood a vampire needs to heal injuries.

• The Might Scale, which measure the amount of blood a vampire needs to increase his strength.

• The Discipline Scale, which measures the amount of blood a vampire needs in order to fuel his Disciplines.
