Due to having evolved to hunt in the darkness of night and hidden places to keep their identities a secret, the ghoul’s have evolved dark vision of 60ft. This allows them to see in shades of white, black, grey and red - this allows them to follow the blood trails of those that they’re hunting.

Due to their nature as cannibalistic entities, the ghoul race find themselves battling their own instincts to hunt down prey depending on the levels of hunger that they’re suffering from and their personal morals and beliefs. You may find some indulgent ghouls who eat just because and never suffer a day in their life, or you may find those who eat just to survive.. or those who literally starve themselves as they’re against their own nature (normally found in the One-Eye variant.)

The hunger may be suppressed by drinking coffee (one cups worth is usually around 5gp and can be prepared for within 10 minutes and/or during a short rest.), or by simply eating flesh and blood. Below is a table of detriments that certain levels of hunger can bring. The ghoul cannot consume anything other than flesh or coffee, as nothing else will contain nutritional value or even good taste. If they choose not to or unable to, they must make a constitution saving throw (DC: 8 + days of hunger), or take 2d10 poison damage. (At level one when you start, the ghoul does start off with humanoid flesh instead of the regular adventurers rations).

• Drinking coffee sets back the hunger by one day.
•  Eating a meals worth of humanoid flesh, dead, sets the counter back by two days. 
• Consuming a living humanoid sets the counter back to 0.
• When you collect flesh rations, they will have the Same effect as coffee and only last 48 hours after collection before they rot. If you choose to consume rotten flesh it pushes the counter forward an extra day.
• If not well practiced in chewing regular food and drink, or forced to eat it, you have the uncontrollable urge to throw up and can push the counter forward an extra day.

The hunger table:

• 0 days = No effects 
• 1 day = -1 to charisma rolls, irritability and high sense to blood.
• 2 days = -2 to charisma rolls, -1 to wisdom rolls. The ghoul seems obsessive over something to eat and quick to threatening situations.
• 3 days = -3 to charisma rolls, -2 to wisdom rolls and -1 to strength rolls. Movement speed is reduced by 10 feet. The scelera of their eyes uncontrollably turn back to their natural black with a jittery red iris. 
• 4 days = -4 to all rolls. Upon smelling humanoid blood/flesh, you must make a wisdom saving throw (DC: 15) or else be thrown into a crazed hunger. All attack rolls in this state are made with disadvantage and are counted as 1d4+Proficiency bite and claw attacks, which can end the crazed hunger if they successfully hit and consume something. The ghoul MUST attack the closest humanoid to them, ally or not. Taking damage allows the ghoul to retake the save. GHOULS CANNOT ACCESS KAGUNE AT THIS LEVEL OF HUNGER.

Instead they use a bite attack, 1d4+Dexterity modifier in damage and on a hit heal half the points dealt from consuming the flesh. Note, this cannot be done on anything other than a humanoid; and on a creature of undead, a constitution saving throw of DC:10 + damage dealt, must be made or they will suffer half the damage done to their HP instead of healing it. If a creature is willing it makes this a lot easier.

Ghouls have a certain biology which separates them from other humanoids which is that they have an extra organ hidden within the back part of their bodies. This organ is one of the main sources for their healing factor and contains their very own biological weaponry.
This is called the Kagune.

At level 3, you possess the ability to alter your body into a hunters state, discarding your humane disguises away in order to access your innate powers. During this transformation they grow claws equal to 1d6 slashing damage, their movement speed increases by 10 and they unlock the use of their Kagune. To use their Kagune is a bonus action and does different effects depending on the Kagune your chosen type possesses (Table below). The Kagune usually lasts for one minute, however it is able to be pushed longer but it will result on an automatically added day to the hunger counter.

Kagune table:

• Rinkaku:  These limbs are shown as two or more fleshy and scaly, slightly glowing, needle tipped appendages that sprout from the spinal area. They do 1d6 piercing damage and can grapple the target(s) on opposed strength checks. You gain a tail every 4 levels and plus 1d6 per tail.
• Koukaku:  A coiling blade that travels down the arm in a spiral motion with a surface almost bendable bone-like in texture but not in colour,  this appendage extends the ghoul’s attack range to 10 feet and does 1d8 piercing damage. You gain 1d8 every 4 levels.
• Ukaku:  Wings that are reminiscent of flickering flames, these almost seemingly liquid wings grant the ghoul a jumping speed of 20 feet and can launch a ranged attack of 2d4 piercing damage via crystallised ‘feathers’. You can 2d4 every 4 levels.
• Bikaku: 
• Kakuja:  This Kagune is the rarest amongst ghoul kind and can only be achieved after long and intense training, emotional and biological development and desperate need to protect and fight. A large covering of a strange material, matching the textures of flesh and bone in appearance, this kagune adds the ghoul’s proficiency in AC, while reducing their speed by half, allowing for advanced strength saving throws too.
