|Heroic Action Role-Play|
You cannot contain the corruption within your body. For whatever reason, you leave a disgusting stench and drop off bits of yourself wherever you go. This can be blood, slime, pus, maggots, feces or whatever. The stench can be obvious but temporary, or subtle but lingering.
Gore is not immediately apparent, you don't look disgusting unless you have other flaws as well. It is only the trail you leave that is disgusting. People might not realize this is from you if you are otherwise unremarkable, but they will certainly realize something is amiss. Detectives have a field day with your trail.
