Odin (Final Fantasy XIII boss)

Odin is a boss in Final Fantasy XIII. It is Lightning's Eidolon, and emerges through her l'Cie brand while she and Hope Estheim are traveling through the Vile Peaks. Like all Eidolons, Odin inflicts Doom at the beginning of the battle, and instead of being defeated, Lightning must fully fill Odin's Gestalt Bar.

Odin is an aggressive Eidolon, initially targeting Hope with severe physical attacks and the occasional Thundara. Libra will reveal that Lightning can satisfy Odin by hitting him to get chain bonuses and switching to Medic to heal. Lightning will need to do both over the course of the battle, as Odin's strikes will necessitate healing greater than Hope can supply, so make sure to have the Double Dose Paradigm ready. When Lightning switches to the Commando or Ravager roles, try to have her attack for as long as possible to amass greater chain bonuses. Odin will often guard with Ullr's Shield, allowing for a quick healing break or uninterrupted attacking phase.
