Aeronite (Lightning Returns)

Aeronite is one of two superbosses in Lightning Returns: Final Fantasy XIII, the other one being Ereshkigal. It is found in the Giant's Sandbox area of the Dead Dunes. Upon defeat, it drops 50,000 gil, 9.00 EP and it has a chance to drop a variety of rare components, including both Holy Forgefire and Demonic Forgefire. In it's ordinary form, Aeronite has 38,500,000 HP (58,000,000 HP in it's chaos form, one of the highest amounts of HP of any monster in the Final Fantasy franchise). It requires the player to stagger the boss four times consecutively to do any significant damage to it. Upon starting the encounter, you are given approximately three minutes to stagger Aeronite, after which you have another three minutes to reach the second stagger level and so on up to the fourth stagger level. If you take over three minutes, Aeronite will use Fed Up, a move which will cause it to flee the battle and fully heal itself when it is next encountered.
