Synopsis
cast contagion [<victim>]
Description
A contagious adventurer has nothing to fear if they have no disease to spread; however, if they do, they will act as an infection vector, spreading disease far and wide. For as long as someone is contagious and infected with the plague, they can potentially affect others nearby. Others' chances of being infected are determined by how susceptible or resistant they are to disease, whether they share a formation with the contagious and the level of the disease being spread.
In addition, the contagious will be more susceptible to disease themselves as their own immune system is ravaged.
