Gnartian Mutations

            These are divided into "Good" and "Bad" categories; Psionic (Mental) and other unobvious Mutations are most often considered positive, a blessing, but observable Physical Mutations - even those with potentially useful side effects - are considered a sign of degeneration, a curse, and those afflicted are most often shunned. Good Mutations can be used 1/day, Duration 1 Turn, some Mutations can be employed simultaneously &/or in conjunction, but only one can be activated/rnd.  When exposed to Radiation, a Failed Save of 1=gain one Bad Mutation, Save of 20=gain one Good Mutation.
