Soucouyant

The Soucouyant is an old woman who has made a pact with the devil to be able to change herself into all kinds of different forms like a ball of fire or animals.
Ways to kill a Soucouyant
Traditionally, you must throw a handful of salt or rice or other small grains by your door or window. That way she won’t be able to leave until she has counted every last grain. Hopefully, you can keep there until the sun comes up and she’s caught without her skin.
Or you can beat her with a big stick when you encounter the ball of fire. The next day the bruised and battered old lady down the road is revealed as the local soucouyant.
Of course if you already know who she is, the task is simpler. After she leaves her house on her nightly outings, you take her skin and rub the inside liberally with salt and pepper. Then when she returns and dons her skin, she’ll die writhing in agony.
Well, there is always the old crucifix to protect yourself from all evil, but I’m a Hindu, so I don’t think that this will have any effect for me. If you’re Christian feel free to try.
