Bruxsa/Bruxa

The Bruxsa is a form of vampiric witch from Portuguese myth. These monsters consciously choose to be evil. They take the form of beautiful women during the day, and can fully pass as humans. At night they turn into birds and like leading travelers astray, attacking them when they have lost hope. They prefer to feed on children’s blood and sometimes they seek men to impregnate her so that she can have a child, and then consume it. They’re immortal and invulnerable using magic to bring drought, illness, destructive rain, and cause livestock to miscarry. Charms made of fresh garlic can be used to keep this creature away and mixing mashed garlic and holy water can repel the creature if placed on window sills and door frames.
