Devil's Wager

The Devil's Wager is a macro mushroom that possesses spores with proteins like that of CRISPR. Its foul nickname was earned by the mutations caused by the spores. Simple skin to skin contact with the fungus causes infection. Once it invades the body, the protein targets a random subset such as the auditory or optical systems and alters a few DNA sequences from the source. The result can range from Total Organ Failure to superhuman stamina. Usually, the end result is on the more severe and debilitating end, thus the 'Wager'.

The more chilling and universal attributes are morphological changes. From scaly growths and altered eyes to sprouting wings and horns. The afflicted become like fictional depictions of demons. Many are disfigured to the point of anonymity, the lucky few, shunned as monsters. This, of course, is the Devil's aspect.
