Cecil , Refia , Lightning 485 attack Plant killer , CoD , Vaan , and Friend Luneth 571 Attack Fight is pretty harsh at the start . It gets somewhat easier as you kill the other parts though . At 60 % and 30 % of the flower ' s health , someone WILL die unless the tank intercepts or takes the hit it dealt ~ 999 45 times on a single character . Other than that , watch out for status effects and if you have CoD , give her black choker to prevent confusion as comeback is extremely helpful here . Don ' t worry about disease . You can cure individually , but it ' s better to take the 10 % all stat loss instead of wasting turns . That ' s all really . Having osmose will help alot . PS Use raging fist rather than Lightning ' s Crushing Blow . Saves MP and deals about the same damage 3 mp vs 45 mp , ~ 4045 k damage vs 50 k damage . You can get the skill from Friend Point TM , or Ifrit .
