This is a strange breed of vampire unique to Philippines (Visayas, Bikol, Ilikano, Tagalog, Cuyonon). The legend tells a story about a race of mostly women who shape shift at night and feed on their victim's blood and viscera. They particularly like the embryos of pregnant women. There are similar incarnations in Thailand and other parts of South East Asian countries.
Strengths: By day she looks like a normal woman. She can be unaffected by the sunlight unlike the typical nosferatu. She is not exactly a day walker, but she gains most of her supernatural powers as night approaches. She can easily disembowel and feed from victims with her long piercing tongue. Before midnight, she separates from her lower half and sprouts bat-like wings for nighttime flight. Some say she can resemble a bat or a bird in full transformation. She can appear very charming or very scary.
Weaknesses: Aswangs do not like vinegar, garlic or anything spicy. They immediately retreat at the strong odor. For this reason, most Philippine food is made of salty ingredients with generous amounts of vinegar and garlic. This will not kill them unless you discover the lowered severed half of an aswang and pour the elements down it's open side. This will prevent her from being able to reattach. When day breaks, she will die.
