you were (or will) be given a choice in the "type" of vampire you wish to be (you can change this later on the "Elders" page in exchange for "Favor" points). There has been some confusion over the difference between the different vampire types.
The choices are:
Primeval (previously "Animalistic") = Faster Health Restore
Noble (previously "Ravenous") = Faster Blood Flow (from minions)
Modern (previously "Punk") = Faster Energy Restore
Primeval Vampire (designed for fighting)
Health is regenerated 1 every 2 minutes
Energy is regenerated 1 every 5 minutes
Rage is regenerated 1 every 5 minutes
Blood Flow (from minions) is paid every 60 minutes
Noble Vampire (designed for quickly acquiring abilities)
Health is regenerated 1 every 3 minutes
Energy is regenerated 1 every 5 minutes
Rage is regenerated 1 every 5 minutes
Blood Flow (from minions) is paid every 54 minutes
Modern Vampire (designed for performing more missions)
Health is regenerated 1 every 3 minutes
Energy is regenerated 1 every 3:30 minutes
Rage is regenerated 1 every 5 minutes
Blood Flow (from minions) is paid every 60 minutes
