You must complete mark missions: 7, 12, 27, 30, 34, 51, 64 (the 7 undying marks).

Only missions 51 and 64 should give you any difficulty if you haven't power leveled your characters yet, the rest I was able to beat pretty much immediately after finishing the story.

For mission 51 (Attacus), you need to finish all 16 of the Faultwarrens mark missions (missions 35-50), which takes 6 run throughs of the Faultwarrens to complete A1-E6 on the Faultwarrens chart. After completing all of them, you can make one more run through and all of the D island (D1-D4) will have a new Cie'th stone that will take you to E7 where you can fight Attacus. Attacus cannot be staggered and is susceptible to Deprotect, Deshell, Slow and Curse. The key the this battle is having a Sentinel in your party. Twice throughout the battle Attacus will upgrade his sword to a more powerfull one and has the ability to kill someone in your squad with 1 blow if they are not a Sentinel and provoking him. This attack follows his "Concentrate" warning, letting you know when you need to make the switch to the paradigm with the Sentinel. Other than that, do the usual Com/Rav/Rav to get this chain gauge up and hurt him and he will go down eventually.

For mission 64 (Vercingetorix), I used Light/Fang/Hope. My paradigms were:
Sab/Sen/Med (default)
Med/Med/Med (never had to use, but good to have just in case)
Use Fortisol and Aegisol before going into battle. To start out I would cast Poison on the enemy and then switch to Combat Clinic (Med/Sen/Med) and just heal until he went into his invincible Impenetrable Auro ability. This is where you take the time to heal up if you need it and replenish your buffs with the Syn/Syn/Syn if you lost any during his Putrescence attacks. Then I switch to Sab/Sab/Sab and cast poison while the other 2 party members use Dispel to remove the buffs he gave himself, if the poison worked I switch to Med/Sen/Med and repeat everything I just explained, if not then switch to Sab/Sen/Med and cast poison until it hits then go to Med/Sen/Med and repeat. Somewhere around his 50% point, he will start using his Wicked Whirl attack that can wipe out your entire party. The second you see this, switch to your Sen/Sen/Sen paradigm and back to Med/Sen/Med after it hits to heal up. Do this and the Poison attacks should kill him in ~10 minutes!
