Nineteenthborn - Iron Guts

One of the tallest Borns, even more so than the Thirdborn by a great deal. This born typically ranges in color from a pale white to a light brown. Their bodies are covered in muscles however they are also rather thickset all around. They however have a tendency to be able to digest almost anything and gain nutrients from it, thus their nickname. The only complaint, mainly from the Nineteenthborn themselves is the ever presence of a gut due to their system of stomachs. Pureblood

+2 Constitution
Quick Metabolism: Whenever a pureblood consumes any food of nutrient value they heal (Proficiency Modifier + Constitution Modifier or Strength Modifier) but it takes two turns to take effect. This ability can be used (Proficiency Modifier) times before needing a long rest.
Ultimate Stomach: A pureblood may eat anything of nutritional value but may also gain short lasting abilities from beasts or individuals they consume a part of. The pureblood if the target is still alive must make a finesse based attack that they are proficient in. This bite attack deals (Proficiency Modifier)d4 + (Strength Modifier or Dexterity Modifier) piercing and the target must make a constitution saving throw against a DC of ((Proficiency Modifier + Constitution Modifier) x2) if they fail the pureblood has two choices. They can for (Proficiency Modifier) hours temporarily take the average of one of their attributes and the target's same attribute as theirs. The other option is to gain the use of one of their at will abilities up to their (Constitution Modifier) in uses or the maximum uses the target had for (Proficiency Modifier) hours. This ability can be used (Proficiency Modifier) times before needing a long rest.

Halfblood

+1 Constitution
Durable Health: A halfblood's system of stomachs is far less extensive than that of a pureblood however their system is far more durable instead. When afflicted with poison either by ingestion or simple affliction a halfblood can resist the damage by (Proficiency Modifier/2)d10 + (Constitution Modifier) to reduce the damage by that value. If the damage is entirely negated so too is the effect. This ability can be used (Proficiency Modifier + Constitution Modifier) times before needing a long rest.
Violent Metabolism: A halfblood's stomach has a much more brutal use as well. A halfblood can make a finesse attack to bite a target for (Proficiency Modifier/2)d8 + (Strength Modifier or Dexterity Modifier) piercing damage. The damage dealt heals the halfblood and this ability can be used (Proficiency Modifier) times before needing a short rest.
