Editing Vampire Broods (section)

===Feral Vampires===

If any Vampire ever gives into their hunger or loses all sense of self and higher reasoning (i.e. by losing all their Willpower or Intelligence) they devolve into a beast that immediately attacks another of the Brood; resolve the combat, and if not destroyed the Feral flees into the darkness of the underhive.  Given time they will continue to feed and mutate, and if they survive long enough will metamorphose into a new monstrous form.  Most Vampire Broods will view such beings not only as errant blood but threats to their very survival, for such unrestrained creatures draw unwanted attention to Vampiric infestations....
