Re: [MilkTank] Mighty My Master!
For anybody still playing this, I figured out the EX5 dungeon, or the treasure map dungeon.
The basic way through is to go down, forward, forward, up, up, down, forward.
The final boss is a bitch, though. Just the worst. I found a way to fight it though, that seems to work. I used the girl with a shield, the one with the scythe, and the trident. During the fight, I used all of their specials to chip down a good chunk of health, and then spammed the dash attack back and forth into him to do damage while dodging blasts. I used the trident girl to summon guards to help me and then switched back to shield girl to tank damage.
