Seven long months ago, players of Final Fantasy XI came across a threat worse than the notorious Absolute Virtue. It was he who resided at the end of the Zeni Notorious Monster system, he who waited for adventurers who could climb the ranks and defeat 12 other notorious monsters. It was the Pandemonium Warden.
And the Warden gave FFXI a boost of publicity when the linkshell Beyond the Limitation couldn't take him down after 18 hours of straight battle. This caused the outcry of over-punishing boss battles, and the FFXI team actually dropped their monsters down a notch from all of the heat. A new rule was placed in with the Warden however -- he would despawn after 2 hours if not defeated within that time frame. Sure, he was easier, but the time limit still made him extremely hard.
But now, seven months after his introduction, the linkshell Shard of Apathy of the Remora server has put the Warden down for the count. They successfully tanked through all 10 of his forms, plus his pets, with reportedly 5 minutes left before he was to be despawned. Congratulations Apathy! So when are you running him again?
