Injury and Death

A vampires' body has an accelerated healing process, using their vitae they can repair some flesh wounds easily, unless they're "on their last legs." However, some of these injuries may include deformities in the bones or broken bones. It is much harder to heal bone wounds, simply because you may need bone magick to bend certain bones back into place, if you have been utterly disfigured. Healing the injuries can be a problem as it takes a substantial amount of vitae to heal certain wounds. Wounds that wont be able to be healed, may cause the vampire to fall into Torpor, which could result in them being killed or damaged.

Death
The easiest way to kill a vampire is to tear off the head, severing the brain from the heart, and thus preventing the flow of vitae into the brain. Which will result in killing the vampire. (In OOC terms, at the moment I think deaths are two days? - Someone should edit this if I'm wrong.) There are also other ways to kill a vampire. Another of the main ones being fatally wounding the heart to the point it cannot function anymore. The last but not least main way most vampires are killed is by magery or blood, a vampire may be killed by consuming another vampires blood as the vitae in the other blood will cancel out the vitae in the vampires current body, thus they would die through inability to control their vessels. Magery related deaths could also be disintegration by flames to destroy the vessel, or other mans such as crushing the vessel beyond repair.
