The Amphisbaena is an enemy in Final Fantasy XIII. It is the monster the player first sees during the opening credits—just after the Square Enix title appears—when the game is turned on for the first time. The Amphisbaena is first encountered in the Archylte Steppe, and quite a few can be found flying around, and eventually hovering above the player, once it spots the party. Numerous Amphisbaena can also be found in The Cloven Spire after defeating Dahaka. A single Amphisbaena can also be found in The Palisades.
The Amphisbaena can be easily defeated by following a Delta Attack (COM/RAV/SEN) and Mystic Tower (RAV/RAV/SEN) combinations, switching to Solidarity (COM/MED/SEN) or Combat Clinic (MED/MED/SEN) to heal or dispel status ailments. The key is to never have the primary attackers afflicted with the ailments before staggering it. A Sentinel will help, as Amphisbaena's Feeding Stoop ability can inflict severe damage to unprotected characters. Once staggered, the Amphisbaena does not last long, especially since its actions can be halted.
Amphisbaena is a Greek mythological creature. It is a serpent with a head at each end who was spawned from the blood that dripped from Medusa's severed head.
Amphisbaena is also a type of genus of the family Amphisbaenidae, commonly referred to as the "worm lizards." This genus includes over 100 diverse species.
