  Dark Bahamut has a very high Luck stat, thus evading most normal attacks, no
matter how high the character's Accuracy is, unless they also have a high
Luck stat themselves and/or use Aim.

  Dark Bahamut's Overdrive, Mega Flare, inflicts Delay (strong) and deals between
40,070 to 45,246 damage to the whole party. The damage from Mega Flare can only
be reduced by another aeon's Shield. It also removes most beneficial status
effects, except for Auto-Life. His Overdrive gauge increases by 10% when using
his physical attack or when targeted by an ability.

  Dark Bahamut is hard to hit with his high Luck stat. With 255 Accuracy and 35 Luck
(regarded as the lowest stats to reliably hit Penance), the player can have Rikku
mix two Healing Springs for Ultra NulAll, giving Aim x5, and enough accuracy to
mostly hit Dark Bahamut.

  The player should also dispel Full Break and heal before every fifth attack is
countered with Impulse.

  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: one character should have a weapon with
Counterattack or Evade & Counter, and use Sentinel every turn. If this character
does not have enough Luck to hit Dark Bahamut, they should be given the effects of
Aim five times as well. The character's HP and Defense must be high enough to survive
Dark Bahamut's physical attacks. Having Protect, Cheer, and/or armor with Defense +20%,
can help with this. It is also possible to do this without using Sentinel
(by having the entire party defend before Dark Bahamut attacks), but this is less
convenient since the entire party must then be capable of surviving and counterattacking.

  A risky tactic for parties having trouble hitting him due to Dark Bahamut dodging 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. This trick can also be used
against Dark Yojimbo, using Kozuka to inflict the required breaks.

  Mega Flare can be survived by summoning an aeon or by casting Auto-Life on everyone.
The Overdrive is not as damaging compared to those of other Dark Aeons. Party
members with Break HP Limit at around 50,000 before Dark Bahamut executes his
Mega Flare will also survive it. After soaking the damage, the party should fully
heal with the Final Elixir mix. It helps if all party members have Strength,
Defense, and Agility at 255. Luck is sufficient at 80 or higher.

  As with any other enemy, Dark Bahamut can be killed instantly by Yojimbo's Zanmato
attack. This can be used to obtain Sun Crest needed to power up Caladbolg if the
player missed it. This will likely take multiple attempts since whether Yojimbo
uses Zanmato or not is unpredictable, even when his compatibility with Yuna is high.
