Bahamut
Bahamut the sixth Eikon, which Clive gains access to, and he earns it once you’ve completed the 
Fire in the Sky Main Scenario Quest. At this point, you’ll have to make some decisions about which Eikons to include in your Eikonic Ability Set, and some of your Eikons are going to get left behind.
Bahamut’s attacks are a bit all over the map. There’s no doubt that he has one of the strongest attacks in the game with 
Gigaflare, but many of the other abilities require you to adapt your playstyle or stick to a heavily defensive position for sections of the fight. This makes it tough to justify using many of his moves.
Wings of Light
Eikonic Feat
Begin casting Megaflare. Press 
to execute. The length of the casting determines the potency of the spell.
Tips and Tricks
- Nowhere is the statement above more evident than with Bahamut’s Eikonic Feat. This is an ability that requires you to play entirely from a defensive perspective while you wait for “Megaflare” to charge up.
- The benefits that Wings of Light provides are that it allows for quicker movement around the battlefield, and you can use an
dodge to charge Wings of Light more quickly. - Does a Megaflare help in battle? Absolutely, but it can be slow and painful to wait for it to charge up completely. In fact, the only way to charge it quickly is to dodge enemy attacks as soon as possible, which means you need to be familiar with the attacks you can expect from the enemy you’re facing.
- It’s generally recommended that you use other Eikonic Feats over this one. It can deal a lot of damage if you fully charge Megaflare, but this is offset by the amount of time you spend not attacking.
- Note that you can attack with
Impulse orbs active by pressing 
.

Reflection of Light (Wings of Light)
Impulse
Eikonic Ability
Summon multiple spheres of light that, upon striking an enemy, deal it continuous damage, binding it to the spot.
Tips and Tricks
- Impulse is a misunderstood ability. The key thing to remember is that after you summon the spheres of light, you need to detonate them again by pressing the ability one more time.
- The spheres of light will change color twice after you cast them—the first time, they begin to glow, and the second time, they switch from a blue light to a yellow, flashing light. Detonating them after their second animation change is how you deal the most damage with this ability. Executing the ability in this way ensures that the spheres do maximum damage while they are summoned and when they explode.
- That’s all the strategy there is to know about this ability. It’s a fun one that you can add to your Eikonic Ability Set if you choose, but there are comparable and more effective abilities available.

The Will of Light (Impulse)
The Breath of Light (Impulse)
Flare Breath
Eikonic Ability
Breathe forth a plume of light-aspected flame that both nullifies magic and deals continuous damage.
Tips and Tricks
- This is a medium damage ability that requires you to either be close to a group of enemies or to walk Clive forward slowly and around the battlefield until his Flare Breath also sweeps up other enemies. You can see this strategy being applied in the animation above, as well as in the demonstration animation within the game.
- This move’s most significant drawback has to do with its slow animation that requires Clive to stand around for quite a while, how it leaves him open to attack from other enemies while he’s casting it, and the challenge of trying to get it to hit multiple enemies. The amount of damage you can achieve from this ability is generally not worth all this effort.

Satellite
Eikonic Ability
Summon multiple light-aspected familiars that attack any enemy on which Clive uses magic.
Tips and Tricks
- At first, it may appear that this ability doesn’t do all that much, but if you’re comfortable using
Magic, 
Charged Magic, and 
Magic Burst during fights, Satellite can significantly increase the amount of damage that Clive deals and, more importantly, attacks from Satellite can help him rip through an enemy’s “Will Gauge.” - Their most significant strength is the “set it and forget it” approach. Quickly cast a Satellite at the outset of a battle and just let it add to Clive’s regular attacks and play as usual.
- Note that Satellites can be used while you’re charging Wings of Light.

Gigaflare
Eikonic Ability
Fire a massive beam of overcharged light that burns any enemy it hits.
Tips and Tricks
- Not only is Gigaflare Bahamut’s most powerful ability, it’s also one of the most powerful abilities in the game. This is evident from it being one of the few abilities with a 5 out of 5 star strength rating, one of the few in the game.
- Gigaflare is most effective when the enemy is immobilized or, ideally, when they are staggered. Additionally, it has a minimal impact on the “Will Gauge,” which means it has a low effect on the damage multiplier that occurs when an enemy is staggered. Try to save Gigaflare until the end of a stagger window to maximize the damage that it does to an enemy (using
Diamond Dust first is a great strategy). - Don’t forget to aim while this attack is being used! Time will slow down during a Gigaflare cast, but if an enemy isn’t staggered, it will continue to move slowly, so you may need to rotate the beam with
. Additionally, the beam will aim directly at the center of an enemy by default, but if you’re trying to stack the damage with a 
Lightning Rod, you may need to adjust the beam direction to make sure it hits both the enemy and the rod. - This ability should be used purely as a damage dealer, and it’s one of the most effective means to build up high damage counts during a stagger.
