Mithridates is a mark in Final Fantasy XIII fought in Mission 27 and is one of the Undying. The Cie'th Stone for Mission 27 is located on the Cloven Spire of Taejin's Tower. Mithridates is found on the Ground Tier, but for it to come out of hiding the player must first connect the main lift from the Cloven Spire down to the Ground Tier. This is because Mithridates is lured by music, such as that played by the main lift as it moves.
