Dark Bahamut is one of the most difficult Dark Aeons to defeat. After every five of player's attacks (counterattacks do not count), Dark Bahamut counters with Impulse, which can Petrify the characters who are not protected against it, and will shatter the character if they are KOed as well, and they will be out of action for the rest of the battle. It also inflicts Slow, Full Break, and Delay.
Dark Bahamut has high evasion and can be difficult to hit with normal attacks.
As with any other enemy, Dark Bahamut can be killed instantly by Yojimbo's Zanmato attack.
While Stoneproof armor is useful in this battle, Ribbon is always the best option, and Slow, which can be dangerous, can be prevented with Auto-Haste. The counterattack can be avoided entirely by having a character cast Sentinel.
If the player does not have any Ribbon or Stoneproof armor to survive Impulse, there is an easy, but long/boring way to defeat him: all party members must have Counterattack or Evade & Counter abilities. The only thing left to do is to use Aim to be sure to hit him, and wait for Dark Bahamut to attack and the counterattacks will slowly kill him. The party's HP must be above 25,000 to be sure to survive Dark Bahamut's physical attacks. Instead of using a Ribbon the player can use armor that consists of Slowproof, Auto Haste, Stoneproof, and Auto Phoenix or Auto Protect.
A risky tactic for parties having trouble hitting him due to Dark Bahamut's tendency to dodge physical attacks is to set Overdrive Mode to Stoic, then use Impulse to 'farm' Overdrives, which are guaranteed to hit him; as Impulse inflicts Full Break, the player should dispel them from two of the three party members, and the third will have their gauge maxed out when struck; the auto abilities mentioned above can help make this less difficult to maintain due to having to reapply Protect and Haste. The trick can also be used against Dark Yojimbo, using Kozuka to inflict the required breaks.
Mega Flare be survived by summoning an aeon or by casting Auto-Life on everyone. It helps if all characters have Strength, Defense, Magic Defense, Accuracy, and Agility at 255. Luck is good at 80 or higher.
