Vargouille

These strange, evil outsiders resemble gaunt, red, skeletal heads, with pointed bat wings where their ears should be. They roost in places infested by evil, and despite their unusual appearance they are rightly feared by adventurers. This is because they possess two abilities (which are used for both hunting and reproduction of their foul species). The first is a mind-rending shriek, which immobilizes their victims. The second, a much more gruesome power, is their kiss, which spreads a disease that immediately begins transforming any humanoid victim into a vargouille. First, the subject's hair falls out, then, their ears begin to form into bat wings. Within 24 hours (sometimes even less) from the kiss, the subject's head will be clouded by thoughts of evil, as it pops off their body, and flies away a fully fledged vargouille. Although there is a remedy for this affliction, it must be administered as soon as possible, for once the afflicting person changes into a vargouille, no power yet known can change them back. If one is fortunate enough to have been kissed during the daytime, it should be noted that the transformation can be stopped by exposure to sunlight. While this will slow the transformation, it is not a cure for the disease, which will begin again once the subject is in darkness if it is not cured.
