Scarlet Born are born hunters. When tracking using the Survival or Investigation to track a target, you gain advantage.

Scarlet Born have dark vision up to 60ft, and are able to see in shades of grey, white, black and red. This is active at all times, and doesn't matter whether or not their kakugan is active. 

Your Constitution score increases by 1.

When creating your character, roll a d20. If the die lands on a 1 to 5, your Scarlet Born is a Koukaku type, if 6 to 10 it is a Ukaku type, if 11 to 15 it is a Rinkaku type, and if 16 to 20 it is a Bikaku type.

Koukaku - This type can create blades or drills that spiral down to the elbow. From here, it creates a point that stretches to the arm. The appendage that they create is particularly harder than other types of Scarlet Born, and are often able to absorb more blows before the appendage breaks. However, due to the higher durability, this type of Scarlet Born suffers from a movement speed penalty.

Ukaku - This type can create wings that can appear from either shoulder blade. Ukaku type Scarlet Born are particularly faster than other types, and as a result of the wings, are often able to glide and fly when they get stronger. Due to this however, they're not as durable as the other types of Scarlet Born.

Rinkaku - This type can create tentacles that can sprout from the lower back. Rinkaku type Scarlet Born are gifted with a healing factor stronger than the other types of Scarlet Born, and are able to heal more from a typical meal. Due to this however, they're not powerful as other types of Scarlet Born.

Bikaku - This type can create a tail that sprouts from the tailbone. Bikaku types are allrounders, taking traits from each of the other types with a minor penalty to each. Due to this however, they're considered to be not as specialised as other types of Scarlet Born.

Scarlet Born, through their curse, are unable to survive on regular food that the other races of the universe are able to eat. However they are able to process the flesh and innards of humanoids including but not limited to elves, dwarves and humans. A Scarlet Born is able to survive a full month without eating, however their hunger drives them to the point of insanity after 3 weeks.

Hunger Points - 

Stage One - Up to one week; The Scarlet Born is fine. No penalties to skill checks.

Stage Two - Between one week and two weeks; The Scarlet Born begins to become irritated, and easily jumps to hostility. -1 to charisma based rolls.

Stage 3 - Between two weeks and three weeks; The Scarlet Born is starved, and their signature kakugan develops in the eye constantly; a black scelera and red iris. -2 to charisma based rolls, and -1 to wisdom based rolls.

Stage 4 - Between three weeks and four weeks; The Scarlet Born has become desperate, and will attack anything they deem edible. If they smell the flesh of a humanoid they can eat, they must Wisdom saving throw (DC:15). On a successful save, they will temporarily calm themselves. On a failed save however, they must attack the target regardless of how they stand with the target. Attack rolls done like this have disadvantage, and count as 1d4+proficiency modifier. If the Scarlet Born can hit and consume a piece of flesh, the animalistic hunger will fade and they will return to stage one. -4 to all rolls.

The Scarlet Born have adapted to their unique physiology, and thus have created a better way to fight.

Claw - 1d6+dex modifier*

Bite - 1d4+dex modifier*

Enhanced Strike - 1d6+str modifier*

*Unless at Stage 4 hunger, replaced by prof modifier.

Due to the physiology of the Scarlet Born, their body's innate healing ability is increased when eating flesh. When a successful attack is made using the Bite action, you may heal half of the damage done.
