Wave 1 - You’re in control of Dunban for this battle and you’re up against a difficult Lv 90 Metal Face. He’s not too different from his final Story encounter but the main threat is the Custom Grand Shot Art that will Daze the entire party, something that will greatly delay the battle. He will usually attempt to use this once his HP falls below 50% HP so try to have a Chain Attack ready and then trigger it to inflict Daze on him and cancel the Art. Other than that, Opt for the Peerless Aura for Dunban so that you increase your damage output.

Wave 2 - This second battle is even tougher, you’re up against a Lv 99 Mumkhar that’s out of his Mechon. This means you’ll have to deal with his quick attacks and the fact that most of his Arts will inflict Debuffs on your entire party. The largest threat this time is Mumkhar’s ability to use an Instant Death Art once his HP drops below 50%, once again you’ll want to make use of Chain Attacks to control the flow of the battle and deal large amounts of damage at once. Peerless should once again be your Aura of choice and focus on trying to keep him Toppled where possible to limit the damage you receive from Mumkhar.
