Final Fantasy: 15 Most Brutally Difficult Boss Battles
9. Adamantoise - Final Fantasy XV
Oh hey, isn't that an amazing mountain?
You might find yourself saying this when passing some scenery in Final Fantasy XV. Then you take a quest, and you find out that the mountain you admired is actually the back of an absolutely flippin' ginormous Adamantoise.
Not content with being literally as big as a mountain, Adamantoise is Level 99 and has over 5 million HP. Given Final Fantasy XV doesn't allow you to do excessive amounts of damage like, for example, Final Fantasy X, this battle can take a very long time, sometimes multiple hours.
With its massive bulk and range of attacks, battling the Adamntoise becomes a game of movement and using your abilities strategically. It's also an exercise in patience, as chipping away at its health will seem like quite the slog.
Before the game was released, the director of XV stated that beating Adamntoise would take 30 in-game days. That's 15 hours in real life. Thank god this was nerfed by the final release!
Unlike loads of other Final Fantasy superbosses, Adamantoise can drop some useful stuff! You can get some Adamantite, which is used in elemancy, Adamantoise Meat to cook the unique recipe Longwythe Peak, and an accessory to boost your HP to 9999.
