Subversion. I forgot the timing, but it's fairly regular--just subversion whenever he's going to heal. I *think* he heals on the 3rd turn, then every 2 turns or other turn?
Biological also uses subversion, and Psychological needs level 2 retrograde to do the same thing.
Just respec and get subversion for that battle, it's like Dr. Herredgoss or something of Sonny 1.
