phreak
As with any being, over time mutants went through an evolution. That final outcome making them slightly different from what they were before and hence becoming Phreaks. As with their ancestors, Phreaks have the latent talent to strengthen their minds and bodies. Like mutants they have the ability to cause fear in their enemies and change their appearance, but unlike their predecessors, they have gained the ability to use plagues and epidemics to their advantages. Because of these abilities they have gained the resistances to both poisons and diseases. See showrace phreak for more details.
