Half-Life

Radiation takes a terrible toll on the subject and leaves her a mere shadow of her former self. Her skin becomes a dry mass of flaking skin; her hair falls off; and her eyes gain a piercing, green glow but recede deep into her skull. Loose, yellowing teeth rattle behind dry and cracked lips. She becomes unable to obtain sustenance from food or drink, but instead draws power from radiation. Mutants cursed with this affliction often mutate more and more, as they constantly seek out new sources of radiation.
Type: Major negative.
Effect: All of the character’s abilities decrease by -2. The character becomes immune to all damage and poisoning from radiation, as well as all radiation-based mutagens that aren’t of intense level—indeed, instead of being harmed, she needs to spend time close to a source of radiation to survive, or die of the equivalent of starvation. It’s not uncommon for these mutants to carry isotopes or other sources of radiation around with them to provide them with sustenance.
The mutant also gains the ability to automatically locate sources of radiation within a 10-mile radius around her and gauge their strength, as well as a psychological compulsion to seek them out—the stronger the source, the harder it is to resist its siren call. When encountering a source of radiation, the mutant is compelled to bask in its radioactive glory; to resist it, she must make a Will save at the same DC she would use when resisting mutation. (Thus, a character who encounters a source of intense radiation cannot help but to seek it out, and will inevitably mutate further unless someone restrains her and removes her from the range. The character will fight those who try to keep her from reaching her destination.)
The character always receives a +2 circumstance bonus on Intimidate checks due to her horrifying condition.
Biotech: No.
