What appears to be your common every day sheep walks in your direction. Once it is close, it lunges towards you, teeth ready to bite.

Black Sheep are regular sheep that have been imbued with fell necromantic magics. They appear in all ways to be normal sheep. What sets them apart is their lust for flesh. Flocks of these foul creatures are often kept by the fiendish denizens of Hades, who favor the taste of their flesh, and might be found dwelling in the gloomy rift valleys of the dismal outer plane.

Combat
A Black Sheep usually just approaches its victims and attacks them. They do not attempt to use any special tactics, but because of their appearance they often catch their victims by surprise. Once a Black Sheep has successfully bitten its victim, it attempts to hang onto her and use its Eat ability. If there are more Black Sheep than there are victims, as is often the case when someone is unfortunate enough to run into a flock, multiple sheep join in on the grapple and use their Eat ability simultaneously.
   Create Spawn (Su): A creature reduced to 0 constitution by a Black Sheep’s Eat ability or a creature effected by a Black Sheep’s Infectious Bite ability is turned into a Black Sheep Spawn. See below for information on Black Sheep Spawn.
   Improved Grab (Ex): If a Black Sheep successfully hits a creature with its bite attack it may, in addition to dealing normal bite damage, initiate a grapple at +10 as a free action that provokes no attacks of opportunity. Creatures grappled by a black sheep in this way are subject to its Eat ability.
   Eat (Ex): A Black Sheep may begin to consume a victim that it has grappled with its Improved Grab ability. For every round that a creature remains in a grapple with a Black Sheep in this way it takes 1d4 points constitution damage.
   Infectious Bite (Su): A creature that has been successfully bitten by a Black Sheep must make a Fortitude save (DC 18) for every bite sustained or for every round it is subjected to a Black Sheep’s Eat ability. Failure results in the creature becoming a Black Sheep Spawn in 1d6 hours. The save DC is Charisma based. A lesser restoration spell cast on the afflicted creature before it would turn into a Black Sheep Spawn negates this effect. Characters being affected by this ability notice their body slowly becoming more sheep like, starting with the area they were bitten.
   Looks like a Sheep (Ex): A Black Sheep looks just like a regular sheep, despite its name. Characters must make a Sense Motive check (DC 18) to notice that the Black Sheep is in fact not a true sheep. Characters who have encountered Black Sheep before, however, may simply opt to attack any sheep they run into.
   Flammable (Ex): A Black Sheep dealt fire damage catches on fire, taking 1d6 burning damage for every round it is on fire. Characters struck by a burning Black Sheep also suffer 1d6 points of burning damage.
Black Sheep Spawn:
Black Sheep Spawn are the products of a Black Sheep attack. Visually, they look like a hybrid combination of a sheep and whatever the original creature was. Keeping the most prominent features of the original creature, and gaining the most prominent features of a sheep (e.g. the eyes with horizontal slit irises, woolly bodies, forward tilted front teeth, and cloven feet.)

This creature appears to have been a hill giant, however it is covered in wool and where it once had humanoid feet and hands it instead has cloven feet.

On hungry days, Hill Giants sometimes harass flocks of sheep. On other hungry days, Hill Giants sometimes get harassed by flocks of Black Sheep. Those days see the creation of Black Sheep Spawn Hill Giants, which are known to some simply as “Black Shepherds” for their habit of leading the flock to its next meal.

Combat
Black Sheep Spawn don’t really bother with plans. If they are faster than the flock, they run ahead and attempt to hold down the biggest creature so that the flock can aid it; if it’s slower it simply goes for the biggest target.
   Create Spawn (Su): A creature reduced to 0 constitution by a Black Sheep Spawn’s Eat ability or a creature effected by a Black Sheep’s Infectious Bite ability is turned into a Black Sheep Spawn. See below for information on Black Sheep Spawn.
