Bahamut
Bahamut is Fang’s Eidolon and he is the fourth Eidolon you gain access to. Fang, Vanille and Lightning will battle Bahamut towards the end of Chapter 10 - The Fifth Ark (Part 2).
Bahamut does not have an elemental affinity in the same way that Shiva, Odin or Brynhildr do. He is capable of attacking with physical attacks as well as magical attacks.
Normal Mode
Bahamut also doesn’t play a specific role in battle in the same way that other Eidolons do. He starts with a fairly low SP Gauge, which means it’s very important to make use of her 
Sentinel role to charge it up as much as possible. The higher the Gestalt Gauge is when going into Gestalt Mode, the more damage Bahamut’s final attack will do.
| Ability | ATB Cost | Description |
|---|---|---|
| Dragon Claws | 1 | Deal physical damage to targets in range. |
| Whirlwind | 1 | Deal physical damage to surrounding targets and launch them into the air. |
| Umbral Vise | 1 | Deal heavy physical damage to target. |
| Inferno | 1 | Deal heavy magic damage to target. |
| Ignis | 3 | Deal magic damage to targets within a wide radius. |
| Curaga | 1 | Restore a large amount of target’s HP. |
| Arise | Auto | Revive from KO with full HP and no status ailments. |
Charging the Gestalt Gauge
Helpful Hint
As a reminder, you can charge his Gestalt Gauge by utilizing the same tactics you used to charge his Gestalt Gauge during the Eidolon battle, namely:
- Yields to those who amass chain bonuses.
- Yields to those who defend against and endure attacks.
- Yields to those who weaken and debilitate their enemies.
As noted above, start off by having Fang apply some status ailments in her 
Saboteur role before having her swap to her Sentinel role to use 
Provoke and absorb some attacks.
Gestalt Mode
Hunting Dive has a chance to miss anytime it is used on enemies that are on the ground (i.e. most enemies). Pulsar Burst is also fairly effective for quickly building a Chain Gauge on one enemy or groups of enemies.
