This walking nightmare resembles a white-haired old woman who looks as though she has been skinned alive, her bloody muscles and sinews pulsing grotesquely.

SQ fiery form, mask evil
As a standard action, a soucouyant in her fiery form can choose to explode in a 30-foot-radius burst of fire that deals 8d6 points of damage (DC 19 Reflex save for half damage) to all creatures in the area. Using this ability returns a soucouyant to her humanoid form.
As a standard action, a soucouyant who has removed her skin can assume the form of a flying ball of fire similar to that created by a flaming sphere spell (CL 8th) for up to 8 rounds. Upon returning to humanoid form, a soucouyant must wait 1d4 rounds before she can assume fiery form again. A soucouyant who enters the same space as a creature stops moving for that round and deals 3d6 points of fire damage to the creature unless it succeeds at a DC 18 Reflex save. A soucouyant in fiery form retains her usual AC, but is immune to non-magical attacks and effects. A successful targeted dispel magic spell or dealing 20 points of cold damage to a soucouyant in fiery form forces her to return to her humanoid form. A soucouyant can assume fiery form a number of times per day equal to her Charisma modifier (6 for most soucouyants). The save DC is Charisma-based.
During the day, a soucouyant has the appearance of an old woman, an illusion created by an effect like alter self; at night the illusion fades, revealing her monstrous nature. While she is ”wearing” her skin, a soucouyant’s evil nature is masked as though by a constant undetectable alignment spell.
Environment any land
Soucouyants are insidious monsters also known as blood crones. They prefer to live near small humanoid societies, assuming the appearance of a wizened old woman. It is only at night that she assumes her true form, when her wrinkled skin peels back and reveals the monstrosity that lurks within, which seeks the blood of those sleeping, unsuspecting neighbors who know her merely as the eccentric widow living at the edge of town. Soucouyants prefer to capture victims for their cruel experiments when possible, and drain such unfortunates of their blood over a course of days or even weeks to sate their sanguinary appetites.
A typical soucouyant is 6 feet tall and weighs 120 pounds. The most powerful soucouyants take it upon themselves to further their spellcasting abilities, and usually possess levels as witches.
