Stinking Blade

An old trick of the lowest kind. Not for the feint of stomach.
Given enough time before battle, you cover your blade in shit, or preferably, rotten corpses.
Since the individuals with weaker immunity died centuries ago, people and animals tend to be quite resistant to wound infections in the Afterfall. However, the amount of micros found in shit is an entirely different thing.
If you manage to inflict a wound to an enemy, your enemy must roll Vigor at standard difficulty.
If he succeeds, his immune system is able to overcome the micros, but if he fails, and somehow manages to survive the battle, he will get a nasty infection called Fleshrot (see Disease).
