In this video I start out at the final save spot right before the room with the patriarch and proto omega in the Omega System. I did not level up for this fight and decided to go after the bosses with my characters as they were around level 40.
I fight and defeat both forms of the patriarch and then fight against Albedo. This is basically another battle which you are not likely to lose because Albedo starts the fight by casting safety level on Rubedo. After that I show the ending and credits of the game.
