Cachexy

Facility with this Discipline is considered the dividing line between what makes a Kindred a Mekhet with a peculiar feeding habit and a confirmed member of the Morbus bloodline. Any Kindred can choose to feed from diseased mortals if he’s willing to risk spreading infection to the rest of the herd, but only the Morbus can turn the effects of their feeding predilection into this formidable and dangerous Discipline.
Cachexy allows the user to selectively spread, inflict or worsen the effects of any of the myriad diseases he carries at any given time. Some of the effects require the character to touch his intended target, while the dangerously high-level ones eliminate that impediment and render users walking biological hazards.
When a Morbus intentionally spreads a disease with Cachexy, the player decides which of the diseases his character has sampled is inflicted. The specific disease isn’t important as far as rules are concerned, but the choice should have some sort of resounding effect on (or be driven by) the themes of your story. For the basic rules on diseases, see p. 176 of the World of Darkness Rulebook.
