So I didn't want to go out like a punk, and decided ultimate Bartz was going to die cid style, terrible synergy be damned. After growth egging the entire team all the way to level 80, dumping a massive amount of orbs to rank 5 almost every skill on the team, using two shared medica rods with double full healers, and giving the dps a bunch of leeching attacks, I beat this bitch for cid mission. I had to put the entire team in the back row, and give weaker people like Lenna +defense accessories. Even with all of the above, I spent over 2 hours tonight making attempts, and failing, usually when he decided to quad shot Lenna twice in a turn.
I can say I feel proud of myself beating that encounter cid mode with the only FFV relic being Bartz's shitty cloak.
