Gamma World: The Infinity Arc
A mutant with this feat is heavily mutated. Whether through mutant parents or as a result of the environment, he has more mutations than average.
Benefit: The mutant gains an additional mutation. The same mutation may be selected more than once (this advances the mutation a level). In addition, each time this feat is taken, the mutant suffers a –2 penalty to Medical Incompatibility checks.
Special: A player may take this feat multiple times.
