eh except that is a ridiculusly difficult way of goin about doing this - heres how i did it - by the time you come across mega tonberrys you will have obtained the cat nip accessory - now equip one of the girls with the gunner ds, keep her at low hp and proceed through the maze - keep the other girls equiped with dark knight ds - pump up special def as much as possible - now when u encounter a mega tonberry ( you usually have no choice but to fight it in order to proceed ) KILL THE SMALL ONE FIRST - after this the mega may oversoul - if not simply kill with trigger happy - now when you do eventually oversoul a tonberry trigger happy FIVE exact shots - Turn the other two girls into gun mages and TRY to et the gunner into gun mage ds - mega t will use Cry i t n and usually kills the gunner girl - after this move i only everhad one girl alive - if yer lucky the gunner will change ds b4 the move - if not jus repeat once more
