Cloud, Warrior of Light, Firion, Onion Knight, Tifa (Did not use)
Mainly it was omni v5 spam. Got him down to around 80k life before he finally got me.
Stuck to using HP link attacks to continue to chip away at his life. Shaved another 30ish thousand off him and got him to 50k.
Was surprisingly effective on the ground. Stuck to using Rope Knife and Reel Axe into Double trouble and was able to knock off 40k and got him to just a few thousand.
Couple of clean up links and he was dead.
Gear was a mix of some 100 gear that I found and lv 60 gear. I'll see about getting the replays up of my go. I made so many stupid mistakes though (bad summon use, screwing up firion's HP link by hitting it to early, and the like)
