|The empire classifies mutants into one of three categories. Approximately 6% of the population of the empire has some form of beneficial mutation.|
Note that disadvantage points for being a class B or C mutants do not count towards the normal 70 disadvantage maximum. Thus, someone who takes a Class C mutant limitation can have a total of 110 points in disadvantages, including the 40 for the class C mutant disadvantage.
Class C Mutant: Far and away, the most common type of mutant. A class C mutant generally has a single mutant ability that is limited in scope and power. The mutant has the ability, but is not able to improve it with practice. An example would be a mutant that can become invisible to normal sight. His mutation will always allow him to become invisible to normal sight, but he will never be able to improve it to also become invisible to infrared and ultraviolet rays. Class C mutants make up 95% of all mutants. Class C Mutant is a 40 point disadvantage and the character must take the Normal Characteristic Maxima disadvantage unless their one mutation is an enhanced characteristic in which case that one characteristic can be above normal.
Class B Mutant: The mutant has one ability (or maybe a very small group of related abilities) that is not limited in power. For example, a class B mutant might have the ability to shoot a lightning bolt from his fingers. Unlike a class C mutant, however, the class B mutant can make the lightning bolt stronger with practice. Thus, it might start as a 4d6 lightning bolt but, over time, get stronger and stronger. Or the mutant might be able to make the lightning bolt do different things as he improves his skill. In game terms that means that, in addition to his normal lightning bolt, he may have other lightning bolts with various advantages and limitations such as area effect, charges, continuous, etc. Class B mutants make up 4.9% of all mutants. Class B mutant is a 20 point disadvantage and the character must take the Normal Characteristic Maxima disadvantage unless their one mutation is an enhanced characteristic in which case that one characteristic can be above normal.
Class B+ Mutant: This is not an imperial classification, per se, but is often used to describe a class B mutant whose single mutant ability is very broad in scope. For example, a mutant who can create a Force Wall, and is able to incorporate all sorts of interesting effects into the force wall such that it can provide life support, light and maybe even movement. Class B+ mutant is a 10 point disadvantage and the character must character must take the Normal Characteristic Maxima disadvantage.
Class A Mutant: To the empire, the class A mutants are the most dangerous and also the most rare. Most player-characters are class A mutants. A class A mutant has a range of mutant abilities, most or all of which can be improved with practice. Class A mutants make up 0.1% of all mutants
There are rumors that the empire also has a Class AA Mutant rating which indicates a class A mutant who has developed his mutant abilities to the point of posing a significant risk to the empire. In game terms, this would probably be a class A mutant with 400 or more points. There might even be a class AAA mutant designation who is even stronger (maybe 700 or more points). Regardless of whether the empire officially uses these designations or not, the media definitely does.
In a population of of 100,000 people, 6000 are mutants. 5700 are class C mutants, 294 are class B mutants, 6 are class A mutants.
