Thin-blooded

Thin blood is a term with multiple meanings in Vampire: the Masquerade. Generally, blood "thickness" is a relative term - lower generation vampires have thicker blood, higher generation vampires thinner. However, the term is also used to refer to Caitiff and vampires of high generation.

In particular, Thin Blood Syndrome refers to exceptionally weak Vitae. A character with Thin Blood Syndrome expends extra Blood Points when using disciplines and has a pool of blood which is never expended except for movement. In addition, Thin Blooded vampires generally cannot sire.

In the Final Nights, Thin Blooded vampires are synonymous with vampires of the 14th and 15th generations. These vampires are not only afflicted with Thin Blood Syndrome, but are also possessed of unusual talents. Many of them are Inceptors, some of them possess an unusual Insight into vampiric affairs, and most rare and disturbing of all they can initiate biological processes, including pregnancy.
