The demonic ghoul also called a ghūl or ghūla, is a much more dangerous version of the ghoul and ghast. This creature appears to be more monstrous than the common ghoul, though there still plenty of similarities to attest to their relationship. Demonic ghouls are believed to be corpses with a demonic spirit inhabiting their body. Similar in a way to vampires.
The demonic ghoul has the hindquarters of a donkey, sans tail, and sometimes the horns of a goat.  They have the same ability to paralyze others, including elves, and are given away by their stench.
Where ghouls and ghasts feed on corpses, the demonic ghoul is not above providing their own corpses by hunting and killing humanoids.  They are also known to eat living children.
The demonic ghoul can also shapeshift into hyenas and can assume the form of the last person they devoured.
The female demonic ghoul, the ghūla, can also pass as a living human woman. It is said they will lure prey back to her lair to seduce and then feed on them.  Children born to these women are still-born but will grow up to become ghouls on their own. 
Demonic Ghouls are undead and turn as Mummies.
Ghoul Fever is a disease caused by the bite of demonic ghouls.  The victim must make a save vs. Poison or become infected. One full day after this failed save the victim loosed 1d3 Constitution and 1d3 Dexterity points.  At this point, they must make two consecutive saves vs. Death to survive.  A fail on one save adds one more day to the disease and another loss of points. Two fails results in death.
A humanoid who dies of ghoul fever rises as a ghoul at the next midnight. A humanoid who becomes a ghoul in this way retains none of the abilities it possessed in life. It is not under the control of any other ghouls, but it hungers for the flesh of the living and behaves like a normal ghoul in all respects. A humanoid of 4 Hit Dice or more rises as a ghast.
Ghoul fever is also present in 10% of all ghouls and 25% of all ghasts.
