I know I have brought this subject up before....it was discussed and opinions tossed around....but...
Most everyone knows I also role the new WW system...Vampire the Requiem...I found in that book a section on properties of the blood...hence the name of this topic...L
it reads as follows....VtR...page 156
Vitae retains its supernatural properties for a few minutes after it leaves a vampire's body and is exposed to the air, and then reverts to ordinary blood. A scientist who examines a sample of former vitae would find a mixture of blood from many sources, with some of the cells broken down.
works for me...LOL....had to share..
