System: The user rolls Willpower T# of 6 to determine the amount of lifeforce taken. The victim rolls Willpower T# of the Attacker's Willpower to Soak this loss. Points lost are first taken from blood pool/gnosis/quintessence/etc., and once that is gone from their wound levels. Each point the victim loses rejuvenates the user, giving him one blood point. Damage dealt with this power is not aggravated unless the user spends a Willpower point when making his roll.
System: The vampire must spend a blood point to activate this power, after which it will last for the entire scene or until the vampire chooses to release it. The vampire's touch deals an amount of damage dice to any creature he touches equal to his current Willpower as well as any damage normally incured. This damage is aggravated and soaked separately but is applied before any damage dealt by the type of contact made. If this power causes even one Wound Level of damage then the victim contracts the Chill of the Grave. Anything with the Chill of the Grave must make a Willpower roll with a T# of 8 after they score any botches in a roll involving a Physical Attribute. Failure indicating a loss of one point from that Attribute. Lost Attribute points are regained at a rate of one per day once the Chill of the Grave is gone. The Chill of the Grave is gone once the victim makes a successful Willpower roll T# of 8, one try per night's rest.
The vampire's body no longer requires blood. His blood pool becomes a Lifeforce pool with a capacity equal to his previous blood pool capacity. He can no longer be blood bonded or blood bond others while this power is in effect. He becomes immune to diablerie and cannot diablerize others because he cannot taste their blood. Blood will not even touch the kindred, coming within only an inch of him! All his abilities that normally require blood will now run off of his stored lifeforce instead. He must use Life Theft to feed from now on. Thaumaturgical abilities and other disciplines will use this Lifeforce points instead of blood points unless they are applicable only to blood points (such as Taste of Vitae). System: To activate this power the user must spend all of his blood pool, be unhurt and have both a permanent and maximum Willpower of 10. Once this power is activated it is permanent unless the user chooses, of his own free will, with clarity of thought and in full knowledge of what he is doing, to imbibe blood. This level of Necropotence is then lost to that vampire and must be purchased all over again. Losing this power in such a way does not cause the loss of any Necropotence powers above fifth level.
