System: just spend a blood point on a small object (jewelry, knife, glove...) and it is done. The drawback is that the link is two ways and others can also use Obedience, Aura reading and Thaumaturgy (engaging the vessel of transference or Vampire ward for instance can be deadly) through it. However, if you are confidant in your Obedience power (supposing you have it) it is not so problematic because you can control whoever touches the object. Also, because of the bonding, the point you imbue in the object is still considered as being in your system (though you can not use it except by touch or Theft of Vitae at any range) and must therefore be deduced from your maximum blood pool. Taking back the blood ends the spell and restores the blood pool maximum to normal. So does destroying the object though the blood point is destroyed and a level of damage must be resisted.
The power is somewhat similar to the previous one except that you make the object is physically part of a vampire's body. You can graft a prosthesis (or jewelry) that will not be rejected by the vampire body during the day: small daggers in place of nails, metal sheet over the heart, body armor. This spell can also be used for torture or to prevent a vampire from regenerating by putting an inert prosthesis in place of the missing body part. This spell does not provide any special means of control of the prothesis.
Making Cybervampires is a little extreme and not necessarily in the spirit of the game. As a result, you can limit this power to one operation and small objects only (a sheet of metal in front of your heart, Freddy-like finger blades, an artificial hand...) but nothing like body armor.
System: You soak the object in your blood (quantity depending on the size of the object) and then place it where you wish it to be, using surgery if necessary. The vampire's body will then accept the object in its present place, regenerating around it (if possible) without expelling it. In fact, when the vampire regenerates, the object itself will also be restored to its normal shape.
There are several drawbacks to this power however. First, the initial surgery must be made while the vampire is casting the ritual, so the pain can be overwhelming, you must spend one willpower point per level of damage inflicted during the surgery process. Then, a certain quantity of vitae dependent of the size of the object bonded in the body itself is dedicated to bonding the object. As a reference, assume that for a piece of armor Armor rating+3 blood points must be dedicated. If only one of these blood points is spent, the spell fails and you take aggravated damage as your body discovers a big piece of alien material in itself equal to the number of blood points which were dedicated to the object -3. The spell also fails if a piece of the object is removed or broken. These are also the two only ways to break this spell. Finally, if the object is large, it will give maneuver penalties (as for armor).
Though the heart and the brain can not be replaced, everything else can be (as proved by a Tscimize torturer) a small piece at a time, if the max blood pool is large enough. Of course failing of several of these spells will result in death.
System: The ritual must be cast just before committing diablerie (meaning the victim must have been restrained) then the vampire will gain a dot in any discipline of his victim which is at least two higher than his starting by the discipline where the difference is largest. No discipline can thus be raised higher than 5 and no more than (caster's generation-victim gen.) (minimum 1) dots can be gained.
There are drawbacks however, since the vampire draws more strongly on the victim's spirit, some of its victim personality will linger in him. The strongest personality trait of his victim will be transferred to the caster as a multiple personality derangement (with a strength equal to the number of Discipline levels gained). Also, if the victim is not of the same clan as the caster, he will become a Caitiff.
An alternative system (Ritual 5) is to make the caster roll (difference in generation) (mini. 1) dice with a difficulty of (10+caster's discipline level-victim's). The number of successes is the number of levels geined in the discipline (limited to a level 5 in the discipline). The derangement drawback should also be kept.
