The Final Fantasy XIV team has a new blog post on the Lodestone that describes the upcoming battle with Ifrit, the Primal of Fire. This new 'battle content' will arrive with the v1.19 patch is released.
The Ifrit battles come in two flavors: Standard for level 30 parties of four members; and Hard Mode for parties of eight at level 50. According to the information posted on the Lodestone, the battles will feature an unfolding story similar to regular quests but that give meaning to the hunt for and final battle with Ifrit.
Players successfully taking on and defeating Ifrit will score some pretty awesome loot in the form of Primal Weapons.
