Final Fantasy Discovery

Test battle against the Eidolon, Odin. Odin is immune to magick attacks, and uses physical attacks like Skyward Sword and Flourish of Steel against you. He will sometimes put up Ullr's Shield, making him invulnerable to all damage while he regenerates health. There is a way to remove it, but I'm not telling! ^_^ If this battle drags on for too long, Odin will quit playing around with you and use Shin Zantetsuken, instantly destroying the party. Auto-Life will NOT save you from this.

Odin stops attacking and begins charging Shin Zantetsuken once he is at 50% HP or lower. Players will have to destroy him before he is able to use it! Defeating Odin will grant players his Nethicite.

Protip: Slow affects the charging speed of abilities, and can buy you extra time to deal with him.

Ancient Text Regarding Odin
As the legend goes, Odin once walked among the Gaian races, and held court over what is now known as the Empire of Palamecia, thousands of years ago when it was lush with dense forests and greenery. Then, it was known as The Twelvewood. Challenged to battle after battle by those who coveted his power, Odin came to believe strength was all that mattered... (the rest is illegible)

Odin is a very high level battle. The party I used in this video were all level 255, specifically built to test this fight. I imagine players will have a much tougher time than I did. ^_-
