Actually all you need to do is kill the left pod cause it has like only 2000 hp and go for the right. once you kill the right, all three die with it. The only reason youd kill the middle one is either AOE moves like Luminaire or Dartk Matter, or if you want to stop taking big damage... My team was Crono Marle and Frog. Crono Confused the left bitwhile Marle and Frog attacked normally. It died. Usually I do Arc Impulse for like 3800 damange or Crono Luminared the crap out of everything while Marle and Frog used Double Cure. they were about 47 or 48, somewhere aroud there.
