The battle against Sin’s Left Sin works similarly to the one with Evrae, as you are on the airship and can command Cid to move in or move out. In fact, you will start the battle away from the Left Fin, so you should try to move in on the first turn you can. The Left Fin has a habit of doing nothing sometimes on its turns, but this seems to be determined on the number of times it has been attacked, as well as if it’s close or far away. When the Fin does attack it will usually do a physical one that hits the entire party for around 1,000 damage or so.
By far, the most annoying move in the Fin’s arsenal is called Negation, which doesn’t have a set pattern and can seemingly be random. Not only does this remove any buffs on your party (except for Auto-Life), it will also remove Armor/Mental Break from the Fin itself. Note that if it is afflicted with Mental Break, it can also use Negation when far away, but this won’t hit the party at all. The last move that the Left Fin does requires it to charge up some energy first, so if you see that, get ready for Gravija on the next turn. This skill will shave off 75% of your party’s current HP, but only while up close.
You should be using Armor Break on the Left Fin, as it is armored and physical attacks are not going to be effective without Piercing on the weapon. Other than that, there’s nothing really too special about the Left Fin. Gravija cannot kill you and in fact, the only thing that can is the physical attack. So, just make sure you heal up after Gravija (a Mega-Potion will work wonders) and you should be fine.
