Ghoul

Grimm Classification:
Slug / Leech

Grimm Title:
Ghoul

Threat Ranking:
D

Appearance:
Ghouls are typically 2 - 5 inches long. They resemble normal slugs, with slimy, long bodies and small red eyes on stalks. Their bodies are unarmored and completely covered in black skin. Its body can be divided into 2 sections, the head and rear. There is a small breathing organ on the side of the head and a mouth with many small teeth. There are no notable features on the rear, however.

Ability:
Ghouls are parasites and amphibious in nature, capable of travelling on moist land or in water. They become prey to a large number of animals and Grimm due to their small size and lack of defenses.

One unusual feature of ghouls is their feeding habit. They suck the blood of grimm,humans and animals alike, They also secrete a venom in their saliva that paralyses victims temporarily (up to 6 hours). They normally feed by latching on to a victim's skin, paralysing them with venom so victims cannot protect themselves as the Ghoul sucks their blood. Ghouls inadverdently also suck a small amount of aura from victims, but do not appear to feed on it as the aura is later excreted.

Fortunately, the amount of blood they suck is very little and human victims rarely suffer from any symptoms except the paralysis. They also may ignore victims with high aura as they know such a victim will have too much aura protecting them and the Ghoul will only be able to suck a small amount of blood. (unless a large group of ghouls target a single victim, they will each drain a small portion of aura and feed collectively)

In addition, Ghouls later excrete the aura they have sucked as slime. They only use this slime for moving their bodies across land, but humans and animals who consume this slime can reabsorb the aura and use it. Herbalists and huntsmen use this slime to their advantage.

Strength:

 * Paralysing venom
 * Amphibious
 * Drains victim's aura and blood
 * Large groups can be found in swamps and marshes

Weakness:

 * Unarmored, very easy to kill
 * Needs moisture to survive, will die of dehydration under direct sunlight or on dry ground
 * Salt will dissolve their bodies
 * Will die if does not feed on blood for a long time.

Noted cases:

 * Ghouls were traditionally used to cure blood related sicknesses.
 * Collecting their slime and consuming it provides an instant aura recharge. Herbalists use this to cure patients with weak aura. Huntsmen store slime in bottles to drink and recharge their aura in battle.
 * One particular Huntsman notably used Ghouls in his fighting style, by creating a gun that could fire Ghouls at targets, paralysing them before the huntsman moves in for the kill. (*said huntsman died in an accident when one of his ghouls bit him instead, paralysing him and leaving him lying helpless on the ground while he was killed by the Grimm he was hunting.)
 * One incident where a civillian wading in a lake was bitten by a Ghoul. he fell over in the water and drowned while paralysed.
