Fiend Folio hardback for AD&D. Had to be about 1982, the book was new enough that not everyone had it yet.
I am flipping through this book full of weird monsters and I see this crazy looking flying head with it's guts hanging out. Turns out it is also a vampire! I had no idea there were any other types of vampires.
Lots of research later, which in 1982 meant getting on my bike and riding to the public library, I discovered there were all sorts of vampires out there. But this is the first one I discovered.
What got me most about the Pĕnanggalan in the Fiend Folio was how much like a vampire it wasn't, save for the sucking of blood. It was just a weird creature and I liked it.
What I also like was that this was one of the first vampires I read about that made a link between vampires and witches, two of my favorite topics.
The Pathfinder game has a Pĕnanggalan witch.
The Pĕnanggalan comes from Malaysian folklore and may be distantly related to the Aswang.
Pĕnanggalan (Vampire) (S&W stats)
Hit Dice: 8 (see below)
Armor Class 2;
Attacks: 1 bite (1d6 + blood drain);
Move: 12 (Fly 12);
Challenge Level/XP: 11/1700;
Special: Immune to non-magic weapons, regenerate (3/round), charm gaze, drain 1d4 Constitution points per bite.
The pĕnanggalan head will take 4 HD worth of damage (half what the full creature has) before it flies back to it's body in retreat.
To drain Constitution the pĕnanggalan must attack a victim she has charmed or is sleeping, she can not drain constitution in a combat situation. Male drained to 0 Con become Ghouls under her control. Females drained to 0 Con become pĕnanggalan, but free of being controlled. For this reason pĕnanggalan attack males most times.
The pĕnanggalan will look like a normal woman during the daylight hours. Any attempts at divination (ESP, Know Alignment) will reveal she is a normal woman. Once the sun sets she will retire to a secret place where her head will rise out of her body and fly out in search of blood. Her lair will be protected from the sun and will also contain jugs of vinegar. The pĕnanggalan must soak her organs in vinegar before she can return to her own body after a night's feeding.
The pĕnanggalan can use her charm ability during the day to charm men. If they fail their save she will return to them at night and drain their blood. The men will believe they had an amorous encounter with the woman. Typically the pĕnanggalan will have charmed several men and spread out her feedings so not to spread suspicion when they start to die.
The pĕnanggalan must return to vinegar jugs before dawn. If sunlight strikes her organs she will be paralyzed. If she remains in the sunlight for 10 round she will destroyed.
Likewise running water will destroy her and a line of salt will keep her at bay.
To destroy a pĕnanggalan you must discover her lair and destroy her vinegar jugs and burn her headless body.
The most common remedy prescribed to protect against a pĕnanggalan attack is to scatter the thorny leaves of any of the subspecies of a local plant known as Mengkuang, which has sharp thorny leaves and would either trap or injure the exposed lungs, stomach and intestines of the pĕnanggalan as it flies in search of its prey
