Retrace

Retrace is a Black Magic spell found in Final Fantasy XI that "Transports qualified target party member to their nation of allegiance in the past" and can be learned by Black Mages only.

To learn this spell, the player can buy it from the Auction House, but will be cheaper out questing for the scroll in the quest "The Lost Book". This requires the player to have the Final Fantasy XI: Wings of the Goddess expansion pack installed.
