The circumstances of the victim are a significant determinant of her energetic quality. A sleeping victim will exhibit a heigthened quality of prana, keep this in mind when predating upon roommates and house pets. Such victims are also in an optimal condition to regenerate their ki, so feeding at this time is less harmful.
Victims who are working out, lifting or carrying a heavy object, or dancing will also exhibit a heightened quality of chi as well.
The highest and most bliss-inducing qualities of prana I have ever imbibed came from visibly pregnant women.
Feeding upon an intoxicated individual induces intoxication upon the vampyre, albeit briefly in comparison– the speed at which the vampyre digests exogenous prana is dependent upon her power level (specifically upon a skill I’ve labeled vampyric metabolism). When I first read that drinking from a stoned person who intoxicate the predator, I assumed that one would have to be quite the energy worker to actually manage to get stoned that way. This is not the case.
If you have performed sexual feeding in the past, you are aware of how bliss-enducing and empowering of an experience it is. You will never feel so divine and desirable as you do then.
