Boss: Zombie Dragon
|80||200,000||Fire, Light, Dragon, Undead|
Otherwise, this battle is pretty similar to the Dragon just then, except the zombified version won't bother Braving, making it even easier. Since it's an undead, you can damage it with healing spells too, but you can't KO it with revival items or spells (unlike in the original).
However if you've got some spare SP, you can trigger Bravely Second and KO the Zombie Dragon in one hit with Benediction or an Elixir (or Megalixir if you're wasteful). It's not completely necessary, but it saves a lot of time--and you've got many more bosses waiting for you!
Having disassembled another draconic trap, continue west to exit the area.
This final area used to the first area, not that it really matters. Briefly head south from the entrance, taking a quick moment to survey the precipice along the east. Here, there's a chest with an Asclepius stuffed inside--and no dangerous dragons, surprisingly.
This useful staff can be used to cure ailments and revive fallen party members, which is great for emergencies. Although honestly you should be doing your best to prevent ailments with Status Barrier and avoiding getting KO'd in the first place!
Afterwards, continue along the main trail in a westerly direction. Near the far west, the trail will branch off momentarily. Follow the right-most path to reach your final destination--a chest that contains aa almighty Excalibur III and a powerful dragon boss.
So keep group-casting Elemental Barrier after Freezing Eye to more or less trivialise the fight. You should also give everybody Stop Immunity from a Time Mage or routinely group-cast Status Barrier to prevent Stop. Prescience and Group-Cast All are your best friends here.
