Vampeal metabolisms are horribly inefficient. Being half vampire, they are able to eat normal food for nutrition, as well as blood in their diets. Their own blood is bad at doing the same functions that a normal person is used to. Simply digesting a meal generates vast amounts of heat that exudes from their body. Most vampeals that eat a regular diet have a core temperature of 100-102.5 degrees. Their hearts can't process oxygen as well either. A vampeal's resting heart rate is 100bpm (or beats per minute). Causing them to appear rushed at times of agitation.
