DESC: Your kind are an asymptomatic pathogen carrier (you carry a disease without suffering the effects of it) and are considered immune to any disease that you carry, but not other diseases.
You can transmit it on to others and this can make you very unpopular. The transmission of the disease is by proximity, bite or touch which can be a method that differs from the pathogens normal method. You also can set the difficulty of the disease and you remove the need for the first percentage roll used for the infection rate, in other words you guarantee infection provided they fail their first savings throw. The disease you carry can also contaimenate the area you freqent for the life span of the infectious agent or agents.
For those that become infected by you the disease will progress as described in its listing under pathogens, save for the modified difficulty. You can have more than one disease at a time and for you they do not interact while in your body.
