The Chaotic mode of the World of Darkness has released for Final Fantasy 14: Dawntrail. This pits an entire alliance against a powered-up level 100 version of the Cloud of Darkness, previously seen in the story events of A Realm Reborn. This isn’t just the same fight with a 50-level increase; instead, Cloud of Darkness has additional moves and behavior to keep everyone on their toes. As long as the whole team can coordinate, the boss should prove to be a medium challenge.
