The Ultimate-level duties are high-end raid duties that host a gauntlet of bosses from previous raids or trials, and are intended to be of even higher difficulty levels then the Extreme or Savage levels that previously represented the game's hardest content. These fights require players to have completed the Savage difficulty-level of the previous raid section to even unlock. Due to its high difficulty, Ultimate content is not intended to be "progression" content for the majority of the player base, and is designed solely for those seeking a challenge.
Ultimate content has thus far been strictly recreations of older content, with the Unending Coil of Bahamut being based on the Binding Coil of Bahamut raid series, The Weapon's Refrain being based on the climactic battles of the A Realm Reborn main storyline, and The Epic of Alexander being based on the Alexander raid series.
