Use Poison pots. Seriously. I think we used somewhere around 2000 Poison pots between all 8 of us for our first clear.

Obviously, use your appropriate HQ X-Stat potion as well. Yes, even you tanks.

Also a minor improvement, but its better to have the WAR MT and the PLD OT for the majority of the fight, damage-wise (IE: Have the WAR go first, he'll typically tank most of the fight). This is counting that the PLD knows how to Oath-Dance, tho.
