This is a quick guide on how to defeat Odin. In Final Fantasy XIII, you need to “tame” your Eidolons so that they’ll join you in your adventures. To those who haven’t played yet, Eidolons are like Espers, Guardians, or basically your “Summons”. The first Eidolon encounter is pretty easy to get by, but Odin is by far one of the more trickier fights that you’ll have to do.

Pre-Fight Tips
If you still have shrouds left, the first tip is that you use them (Fortisol and Aegisol). This will make life infinitely easier because you’ll be able to mitigate Odin’s damage and you’ll also be able to dish out damage faster. Another suggestion that I’d like to make is that you prepare the paradigms already. You’ll need the following: RAVAGER – RAVAGER, COMMANDO – MEDIC, and MEDIC – MEDIC.
Fight Tips
At the start, Odin will be on a warpath. After casting doom on Lightning, Odin will start to wipe the floor with you. Try to top your HP off by using a mix of potions and have Hope do the healing. Odin’s Gestalt meter goes up when you heal someone so it’s okay to have Hope concentrate on keeping himself alive.
When Odin does the area-effect damage attack, it might be a good idea to switch to the MEDIC – MEDIC paradigm. After topping off, go back to COMMANDO – MEDIC.
Eventually, Odin will go to a full defensive stance called Ultra Shield. This is your chance to build up Gestalt. Switch to RAVAGER – RAVAGER and bombard him with spells. When he goes back to his original stance, quickly switch back to COMMANDO – MEDIC or else you’ll get killed without a dedicated healer.
The trick here is the quick and timely switching of Paradigms. If you do it properly, Odin should be a goner and tamed in a few minutes.
