Vargouille Template
So during our game of Expedition to Castle Ravenloft [after the knowledge of high deaths was passed around, they came to like it well enough], we occasionally make comments about the first death in the group: when a character became a Vargouille himself. I think I mentioned how neat it would be to have it as a template when the player found out that the town had been overrun and said that somewhere in that group of Undead was a floating head that looked like his old character.
So of course Medusa heads was mentioned.

Here's the template for your viewing pleasure:
Vargouilles
Vargouilles are the heads of beings who are kissed by another Vargouille. It is not a pleasant process and only unfortunate people are forced to go through it.
"Vargouille" is a template which can be added to any living creature except for Plant which has a head.
Size and Type: Type becomes Aberration. Size decreases by one size.
Speed: The creature loses all movement speeds and gains a Fly speed of 30 ft (good). The only time it would retain its previous fly speed is if the creature's flight wasn't tied to its wings or another part of the body below the neckline. In such cases, it uses the flight speed and maneuverability of the Vargouille or its own, whichever is better.
Armor Class: The Vargouille's armor class is modified by the creature becoming one size category smaller [size bonus to AC, losing Natural Armor, and increase of Dexterity].
Attack: The creature loses all forms of attacks except for those emanating from the head [such as bite or headbutt]. If it did not have a bite attack from before, it gains one now. The damage of the bite is as the creature except that the die type decreases by one category. If the creature does not already have a bite attack, the damage of this new attack is 1d6 for Medium Vargouilles, 1d4 for Small Vargouilles, and 1d8 for Large Vargouilles.
Special Attacks: The Varguille loses all special attacks requiring body parts except for the head. Any attack form normally caused through the normal attack part is now added through the bite [such as poison normally dealt through the claw or a negative energy through a slam attack, for example]. It loses all benefits of attacks such as rend and tail slap. Vargouilles also gain the following abilities:
Kiss (Su): A vargouille can kiss a paralyzed target with a successful melee touch attack. An affected opponent must succeed on a DC 15 Fortitude save or begin a terrible transformation that turns the creature into a vargouille within 24 hours (and often much sooner; roll 1d6 separately for each phase of the transformation).
First, over a period of 1d6 hours, all the victim’s hair falls out. Within another 1d6 hours thereafter, the ears grow into leathery wings, tentacles sprout on the chin and scalp, and the teeth become long, pointed fangs. During the next 1d6 hours, the victim takes Intelligence drain and Charisma drain equal to 1 point per hour (to a minimum of 3). The transformation is complete 1d6 hours later, when the head breaks free of the body (which promptly dies) and becomes a vargouille. This transformation is interrupted by sunlight, and even a daylight spell can delay death, but to reverse the transformation requires remove disease. The save DC is Constitution-based and includes a +4 racial bonus.
Poison (Ex): Injury, Fortitude DC 12 or be unable to heal the vargouille’s bite damage naturally or magically. A neutralize poison or heal spell removes the effect, while delay poison allows magical healing. The save DC is Constitution-based and includes a +1 racial bonus.
Shriek (Su): Instead of biting, a vargouille can open its distended mouth and let out a terrible shriek. Those within 60 feet (except other vargouilles) who hear the shriek and can clearly see the creature must succeed on a DC 12 Fortitude save or be paralyzed with fear for 2d4 rounds or until the monster attacks them, goes out of range, or leaves their sight. A paralyzed creature is susceptible to the vargouille’s kiss (see below). A creature that successfully saves cannot be affected again by the same vargouille’s shriek for 24 hours. The shriek is a mind-affecting fear effect. The save DC is Constitution-based and includes a +1 racial bonus.
Special Qualities:
A Vargouille retains all special qualities of the base creature except for those pertaining solely to a body part below the neck. If the creature had spells, the creature must find a way to be able to cast them through verbal means only.
Abilities: +2 Dex, +2 Con, -6 Int [min 5], +2 Wis, -2 Cha.
Feats: It gains Weapon Finesse as a Bonus Feat.
Challenge Rating: The CR can vary greatly depending on the creature and what abilities it loses. In fact, creatures can frequently find themselves becoming lower in CR because they lose a large number of attack forms, for example.
