How do I obtain the following items in FFX-2?

  1. Enterprise - Break HP Limit
  2. Invincible - Break Dmg. Limit
  3. Iron Duke - HP/MP+100%, Agility and Luck+10, all other stats+100
  4. *Key to Success - HP/MP+100%, Luck+100, Double All
  5. Ragnarok - Spellspring (MP Cost = 0)


* I believe getting the Key to Success accessory has something to do with choosing not to fight Garik?
