Ancient Warriors are mission bosses from Final Fantasy XI. They assist Archlich Taber'quoan in Bastok Mission 5-1: Darkness Rising, San d'Oria Mission 5-1: The Ruins of Fei'Yin, and Windurst Mission 5-1: The Final Seal in the shared battlefield "The Rank 5 Mission". While they have pitifully low health, an infinite amount of them spawn and can quickly overwhelm a party. XI
