My Steele tends to walk away from things that scramble her DNA, so she doesn't give in on the radglow. I assume that reduces the radglow's dominance, but I think somebody forgot a max(0,dominance) in the code, as shown in the Encounter log:
Radglow:
┕ Times Encountered: 1
┕ Dominance: -187 %
Radglow:
