> 187 Isobiomorphic. Your character has a resistance to
changes in his physical biology. Any radiation which alters your
character's height, weight, moves, strength, or resiliency has
only a 50% chance of having effect. There is a 50% chance that
raising a skill will have any effect on these attributes (spend the
skill points and raise the skill accordingly, then roll for effect). If
a radiation will be the direct cause of death for your character,
there is only a 50% chance that death will actually occur
