Devil's warts are a species of mushrooms that grow in Oceanyka's temperate zones. They are fairly small and purple tinted. While extremely poisonous on their own, they can be processed into alchemical serums. Before succumbing to multiple organ failure, anyone who ingests these fungi will suffer from an immediate explosion in adrenaline, testosterone and endorphins. This makes them very aggressive, very strong, very agile and extremely bloodthirsty.
