Final Fantasy 13 Tutorial for Barthandelus 2 encounter (Chapter 11 boss)

Corey's tutorial - Make sure before you start the battle to level up your party(In Taejins tower fight the robots on floor five to gain 8,000 fast CP) Then you can go and fight the boss, if you want you can cast shrouds to fight him. Once you start(If you have the shrouds) Go to relentless Assault if party needs healing switch to Diversity and have hope heal you. Continue this till shrouds run out. Now once your shrouds are gone or if you started out with no shrouds then switch to delta attack. Deploy 2 waves of Delta Attack and switch to Mystic Tower to Stagger Barthandelus. Once staggered ether switch to Delta Attack(Safer way) or Relentless Assault(Faster but unsafe). If you need to heal use Combat Clinic. When Barthandelus casts his status ailments switch to combat clinic so Lightning will debuff you or use dispelga but don't worry about all of the statues. Just make sure to get rid of Fog and Pain. Now if he casts doom and you are almost about to kill him say 400,000 health left switch to Relentless Assault and hammer away. Switch to combat Clinic When health is low, if a character dies make sure to renew them. Remember thats only if he casts doom. Tho if he casts doom and you are half way form killing him say 1,000,000 hp or more just retry. Reminders - Level up, Use Relentless Assault to speed things up, switch to Combat Clinic if team mates are low or have Status Ailments such as Fog or Pain, and if he casts doom and your half way from killing him retry.
