"Penanggalen" is an acquired template that can be added to any living creature with 5 or more Hit Dice (referred to hereafter as the base creature). Most penanggalens were once humanoids or monstrous humanoids and nearly every penanggalen is female. A penanggalen uses the base creature's stats and abilities except as noted here.
CR: Same as base creature +1.
Alignment: Any evil.
Senses: A penanggalen gains darkvision 60 ft.
Armor Class: Natural armor improves by +6.
Hit Dice: Change the base creature's racial HD to d8s. All HD derived from class levels remain unchanged. As undead, a penanggalen uses her Charisma modifier to determine bonus hit points (instead of Constitution).
Defensive Abilities: A penanggalen gains channel resistance +4, DR 5/silver and slashing, resistance to cold 10 and fire 10, and all of the defensive abilities granted by the undead type. A penanggalen also gains fast healing 5.
Speed: When a penanggalen is attached to her body, she retains the same base speed as the base creature. When a penanggalen is separated from her body, she has only a fly speed of 60 feet with good maneuverability.
Melee: A penanggalen gains a bite attack and a slam attack when she is detached from her body. Damage is standard for attacks of these types for the penanggalen's size. Both natural attacks are treated as magic for the purpose of overcoming damage reduction.
Special Attacks: A penanggalen retains all of the base creature's special attacks. She also gains the following additional special attacks. Save DCs are equal to 10 + 1/2 the penanggalen's HD + the penanggalen's Charisma modifier unless otherwise noted.
A penanggalen's blood drain special attack causes 1d4 Constitution damage.
When a penanggalen slays a female humanoid via blood drain, and if that slain humanoid had at least 10 Hit Dice in life, that slain humanoid rises as a manananggal at the next sunset. This manananggal is under the command of the penanggalen who created it, and remains enslaved until that penanggalen's destruction. A penanggalen may have enslaved spawn totalling no more than twice its own Hit Dice; any spawn it creates that would exceed this limit become free-willed undead.
Any creature a penanggalen bites is exposed to filth fever—the save DC against this disease is set by the penanggalen, not the disease itself.
A penanggalen's entrails drip with a foul bile that blisters and weakens living flesh. Any creature that is damaged by a penanggalen's slam attack must succeed at a Fortitude save or take 1d4 Dexterity and 1d4 Charisma damage.
Special Qualities: A penanggalen gains the following special quality.
During the day, a penanggalen has the same appearance as she did in life, and does not detect as undead (though she is still an undead creature). At night, she can detach her head and entrails as a full-round action. Her physical but now hollow body exists as dead flesh, but can be destroyed if it suffers damage equal to the penanggalen's normal hit point total. Before a penanggalen can return to her body, she must soak her entrails in vinegar for 1 hour—she can then reattach to her body, at which point any damage done to the body immediately heals (although damage the penanggalen herself suffered remains). A penanggalen whose body is destroyed can never again walk the day in living form, but is otherwise unharmed (save for no longer having a safe way to travel in direct sunlight). When a penanggalen wears her body, she cannot use her natural attacks, her fly speed, or any of her special penanggalen attacks.
