Stats Edit


There are three phases to Attacus, with the second and third phases marked by the abilities Unrelenting Blade and Peerless Blade, respectively. The former lets him use Concentrate, while the latter has him use Meditate instead, and both increase the power of his basic attack.

Whenever Attacus uses Concentrate or Meditate, he will attempt to clear all of his status ailments and debuff a party member with Deprotect and Deshell before unleashing a strong attack, with Meditate being a barrage of attacks that can also inflict Slow. All of Attacus's attacks can dispel status enhancements.


The fight can be surprisingly easy with Fang, Lightning, and Snow with Fang as the party leader. It is recommended to get Stage 10 Crystarium for Lv. 5 Sentinel on Snow.

Using Fortisol and Aegisol is not mandatory, but would make the beginning of the fight easier before switching over to any one of the paradigms with Snow as the Sentinel. It is advised to start with SAB/RAV/RAV, casting Deprotect and Slow. Slow is more important as it lengthens the interval of Attacus's special attacks. Once Attacus is afflicted with the two debuffs, the player should switch to SYN/RAV/RAV for Bravera. Only Lightning and Fang need it. The player should then switch over to RAV/RAV/SEN and bring the chain gauge up to 300%; then switch to COM/COM/SEN.

Whenever Attacus uses a special skill and attempts to clear his debuffs, the player can switch over to SAB/COM/SEN and recast Deprotect and Slow, then switch to SYN/COM/SEN to recast Bravera and Haste on Fang and Lightning. When the buffs and debuffs are on, the party should stay in COM/COM/SEN. The party will not have to heal Snow because he'll use Mediguard.

If neither Fang nor Lightning can survive the initial period when the party is raising the chain gauge before Snow shifts to Sentinel, one can change the paradigms to have Snow as the Sentinel in all of the paradigms. One can also set Lightning as Ravager while Fang is buffing/debuffing instead of Commando to raise the chain gauge even higher. With Snow remaining as a Sentinel indefinitely, Fang and Lightning can spam Blindsides as Commandos to rack up damage.

This fight can also be completed relatively easily with Lightning, Fang and Hope, as long as the player has developed Lightning in the Sentinel role to at least the point where she gains the defend ability, Elude. It is not necessary to have developed the characters in roles outside of their initial roles. It is also not necessary to have any level roles, but the increased health obtained from working towards the level 5 boosts is helpful.

Once Attacus uses Peerless Blade it may become necessary to use SEN/SEN/MED whenever he begins using Meditate, assuming he isn't provoked already. With Lightning as the leader she can use Elude instead of Provoke, and if it hits Lightning or Fang, they should survive easily, and Hope will quickly heal them; if it hits Hope, the player should switch to MED/SAB/SYN and use Raise (or Phoenix Down), then allow Hope to rebuff himself.

Attacus is immune to Random: Instant Chain. Although it can eventually be staggered at 999%, and can be launched when staggered, driving up the chain all the way to 999 will likely take too long, as Attacus will cast Doom on the party leader if the battle takes over 20 minutes. If the characters are developed enough, the battle should end before 20 minutes. Summoning an Eidolon also halts the Doom counter.

Low level strategyEdit

As Attacus gains strength whenever he moves to a new battle phase, the player with a weaker party can end up in an endless loop of healing and defending while not getting many attacks in, prolonging the battle for too long for Attacus to use Doom. In this case, the player can try to raise Attacus's chain gauge as high as possible before he powers up his attacks and moves to the next battle stage.

The player can use three Ravagers to drive up the gauge, particularly with Hope and Vanille as allies, as they can't use elemental strikes. Magic won't deal much damage, but will increase the chain. Once Attacus is at around 600-700% chain, the party can resume the attack properly with three Commandos. With a high chain the party can kill Attacus much faster when he is actually powerful. Teaching Hope and Vanille Attack is required, and boosting their Strength to balance out their stats will increase their damage output without hindering the target time.



Attacus is the name of a genus of moths.

Attacus's Japanese name is Spartacus. Spartacus was the most notable leader of a slave revolt against the Roman Republic.
