Pandemonium Warden (FFXI)
It’s easy to overlook Final Fantasy XI, since it is a MMORPG, but that doesn’t mean it didn’t produce some incredibly difficult boss fights over the years. Perhaps the most famous, and at the time of its release, the most difficult, was Pandemonium Warden from the Treasures of Aht Urghan expansion.
Pandemonium Warden was an endurance fight of epic and ridiculous proportions. Back in 2008 at the time of its release, even one of the most skilled linkshells (read: clans) Beyond the Limitation, which were able to take down Absolute Virtue, another FFXI superboss, were not able to hang on long enough to defeat the Pandemonium Warden.
Their best attempt took a staggering 18 hours and they gave up when linkshell members starting becoming physically ill and vomiting. The news of this crazy fight eventually made national headlines, and the attention eventually forced Square Enix to rework the difficulty, and place a time limit on the fight.
