Setup that barely managed to scrap together to work. Sword Trio provides the Striker and Shooter, Sanji provides the Fighter and Ribbitini provides the Slasher. All four classes are needed to gain the ATK Boost from Sword Trio’s Captain. Important note to put a Luffy support on Sanji, otherwise he doesn’t remove Damage Nullification, learned it the hard way.
Map 2:
Use both Sword Trio’s Special to change [BLOCK] slots and boost damage, then attack. I have the new Tashigi as Support to gain Color Affinity, boosting damage. Even with it, we don’t manage to one turn the boss, causing him to apply 5 turns of Special Bind on our top row, and applies 2 turns of Special Reverse to everyone. But those debuffs can be ignored since we already used both Captain’s Special and Special Reverse of only 2 turns can be gained back by moving to the next map.
Map 3:
We finally use Ribbitini’s Special to remove the Bind, triggering Whitey Bay’s Support to remove Despair. Sanji’s Double Special removes the 2 turns of Damage Nullification. Robin’s Special changes the remaining [BLOCK] slots and removes the remaining turns of Despair and ATK Down, with the help of Franky Support. Then lastly, Ace’s Special replaces the enemy’s Territory, and Jozu attached to Ace helped to remove the ATK Down earlier.
