Braska’s Final Aeon, or BFA for short, has two forms, each with their own HP pool. Both forms share a lot of moves, so it’s not too different. Joining BFA is two Yu Pagodas, which are probably the biggest problem with this battle. When both are left alive, they will use Power Wave on BFA, which heals him and removes a variety of ailments and Breaks; it will also increase his Overdrive gauge. Each of the Pagodas only have 5,000 HP, but there is a catch in defeating them. The Pagodas will come back, so there is no way to keep them infinitely away, with their HP being restored to the amount that was dealt to them via the total they were struck. For example, if you deal 3,000 damage the first time and 3,500 damage the second time, then the Pagoda will return with 6,500 HP instead of only 5,000.
This can cause a big problem, especially if you grinded enough to exceed the damage limit of 9,999, but only if you have Break Damage Limit on a weapon. If there’s only a single Pagoda alive, then they will either use Curse or Osmose. The latter siphons all of a character’s MP, while the former inflicts Curse, Darkness, Poison, Silence and Sleep. Pagoda A seems to use Curse more, while Pagoda B uses Osmose more. Lastly, the Pagodas are out of range of melee attacks, so the only one who can hit them physically is Wakka. Their physical defense is a lot lower than their magical defense, although the latter isn’t terribly high.
Moving on to Braska’s Final Aeon, you will start the battle with Tidus, Yuna and Auron in your active party, so switch out as necessary. In addition to the Pagodas filling up BFA’s Overdrive, it will also fill up a tiny amount in the normal manner of attacking and being attacked. Tidus will have a Trigger Command to talk with BFA, which will reset the Overdrive gauge on BFA’s next turn, but this only works twice. In addition to a normal attack, you will also see Jecht Beam, an attack that can petrify character. Should his Overdrive gauge fill up, he will use Triumphant Grasp on a single character that isn’t petrified, hitting twice and possibly inflicting Zombie. If an Aeon is out, the Overdrive will change to Jecht Bomber.
During the second phase, BFA will pull out a sword from his chest. A lot of things are the same, as he will use Jecht Beam and Triumphant Grasp as his Overdrive (Jecht Bomber for Aeons). The physical attack, though, will change to a sword swipe that hits the entire party. You will still have to contend with the two Pagodas, but they are no different. Once BFA’s second form goes under half health, his Overdrive will change to Ultimate Jecht Shot, which hits the entire party for a good amount of damage. If you didn’t use Tidus’ Trigger Command before, it’s a good idea to save it for this Overdrive.
First and foremost, it’s a good idea to have Stoneproof on the characters you will be using the most, since petrification will remove buffs. The biggest conundrum here is whether to worry about the Pagodas or not. Defeating just one will cause the other to use Osmose/Curse, both of which can be problematic. If you go after both of them, then that takes time away from the main boss. Saving Tidus’ Trigger Command for the last portion of the second phase is ideal, since that gets rid of the party-wide Overdrive. Also, other than the petrification taking away buffs, there’s nothing else that does, so feel free to use Haste and other buffs.
Magic is also a viable solution, especially if you got access to Doublecast and stronger magic, like Flare or Ultima. Also, since there is nothing that bothers with Aeons, other than the Aeon-specific Overdrive, you can also use them if you wanted to do so. Bahamut’s Overdrive can break the damage limit and if you’ve built up Yuna’s Sphere Grid quite well, then it should be dealing a good bit. Rikku’s Trio of 9999 Mix is very good in this fight, as you can consistently deal with the Pagodas in a single hit and Overdrives like Tidus’ Slice & Dice will deal upwards of 50,000 damage.
