Bow Lyn and the Dancers

Bow Lyn and the Dancers

The main star here is Bow Lyn with a Brave Bow (doesn't even have to be +). The rest of the team can be any 3 dancers (P!Inigo and P!Olivia are preferred due to Gale/Blaze Dance but you should be fine with any 3 dancers).

You might want a Blue dancer to tank a hit from the starting Red Mage, as that is the only unit you should not kill on the first turn (every other enemy unit is much more dangerous, unless you wish to keep the Blue Mage alive since their stats are identical).

From then on, as long as you keep triggering a high damaging special (I use Moonbow but Luna makes things even easier), even the Armor units will go down easily.
