Wave 1: You’ll be in control of Dunban and up against three Lv 30 Colony Upas and a Lv 31 Mechon M32X. You’ll want to make the Mechon your main target and remember that for your allies to deal damage, you’ll need to Topple it first. Keep Dunban in his Peerless Aura for the Time Attack, it’s the most useful one you can use.

Wave 2: Next up is a Lv 31 Materia Krabble and two Lv 32 Mechon M53X so dispatch the Krabble to leave you with just the Mechon to deal with. Remember to use Gale Slash before you make use of Dunban’s other chaning attacks and whenever Blosom Dance is available, unleash it on the enemy.

Wave 3: Make your way further south to encounter the final wave which includes four Lv 30 Colony Lizards and a Lv 35 Mechon M64X, your first priority here. You’ll have to make full use of Peerless and Dunban’s ability to Topple the enemy to defeat it but once it’s down, the rest should be simple to dispatch. If you’re aiming for an S Rank here, ignore Chain Attacks, the time it takes for the damage output isn’t worth it, especially given Sharla’s choices here.
