||Mana Sphere (x8)
The battle against Bahamut is pretty similar to the one against Spathi, as Bahamut will be charging up for Mega Flare from the very beginning of the battle. It will take him five turns to do this, so you have a timer on your hand before he unleashed it. Outside of that, Bahamut will counter your attacks with physical ones of his own, plus after five attacks, he will also use Impulse. Since you know when Mega Flare is coming, you can use Shield to minimize damage, although that depends if the Aeon you’re using has it.
