So bonds of friendship, I've gotten to Odin twice. The Bahamut fight and the Odin fight are the main issues now. The others aren't really an issue unless something unexpected happens in the 2nd fight.
I'm kinda losing my mind here. I only got these two be missions and a hard mode playthrough and I'm done.
If only save states were a thing.
I would suggest practicing Odin solo a bit so you know what to dodge, block etc.
