Desiccation

Desiccation is a weakness of immortals, Original vampires, vampires and vampire-hybrids that occurs to their bodies. This can be an automated process where their bodies dry out due to lack of blood consumption or blood in their system. Alternatively, this can also be achieved by bleeding out the body, preventing the heart from beating or through various spells or rituals. Siphoning the magic from vampires can achieve a similar effection, though extended siphoning can also result in the vampire's death.
