Patch 2.1

Good King Moogle Mog will returning as a boss fight. More than likely he will be accessible through the duty finder. Please look forward to it.
A new difficulty for Ifrit, Garuda, and Titan fights will be added in this patch as well. They haven’t quite decided if they’ll call them hard, super, ultra, extreme, or any other awesome intense name. I can see it now. “Ifrit, for real this time”.
Also new Hildibrand quests and FATEs are being added.
The Wolves Den, a 4v4 and 8v8 arena will be opening in this patch. You can travel to it by boat from Lower La Noscea, and to enter the arena you must use the Duty Finder.
And lastly, Mists, the La Noscea player housing region will be unlocked in 2.1. Houses are available to Free Companies and individual players for a monetary value.
