Lust: Lust vampires are so named for their power: they appear capable of inflaming passion, inspiring love and devotion, addicting people to its effects, and even shaping people into one another's ideal lover. They are unusually capable at 'rolling' their victims, and feed directly from lust. Their bites are literally orgasmic, and even recalling the bites can cause flashbacks. Likewise, they are capable of inciting physical lust in their targets.
Fear: Fear vampires have the ability to feed on and create fear in those around them. This ability works similarly to the lust in that the vampire who feeds using fear can go longer without blood, though not forever. In addition, they have the ability to allow their body to rot into a decaying corpse or even fall apart without suffering damage. As a result, they are almost impossible to kill without fire. They are able to cause "corruption" with their bite -- unless the victim is sufficiently powerful to resist, even a single bite can cause a victim to decay and die.
Bone: Bone vampires feed off of pain and anger. Unlike the lust or fear vampires, these cannot cause emotions in their victims, only in themselves. Capable of stirring themselves into a blood frenzy, these vampires become revenant-like in their capabilities to withstand pain, their eyes turning entirely black at this time. Bone vampires are capable of manipulating their skeletal structure, often resulting in talons, blades, or various other things bursting from their skin when provoked.
Power: Vampires of this bloodline can consume the supernatural energy of their victims, and have a seemingly limitless well to hold it in. The vampires can pull reserve energy from this aura at will if need be, making them capable of incredible physical feats even when compared to their brethren. As a result of this, they are exceptionally good at commanding groups of vampires, and at being 'food' for the lust bloodline, as both vampires are empowered by the use of the lust. They appear to be similar to the bone vampires in that they are capable of channeling this energy into claws or even extra teeth, although most tend towards magical pursuits.
Revenant: Revenant vampires are wild and animalistic, living only to kill. They do not retain enough of a mind to use any supernatural powers and display an immunity to supernatural powers.
