After you complete the story you will travel further into levels and find a boss at the end. You can come back and fight the boss as many times as you want. You will get large amounts if exp and the rare item the drop.
Fighting Goura (Last Form)
You don't need to use any spells other than
healing spell. You will be in special mono shift
form so just hit him but don't use ultimate move
as it will deplete your DUR guage faster. Use
healing spell when you can't take another hit and
keep hitting him. It should be over soon.
After you beat the game, you can start a new game
on the same save file. if you do this, you keep
your craft night rank (NOT LEVEL!), your cash, your
Beastiary, your weapons manual, and your stored
weapons. this make the game incredibly easy the
second time around.
Getting An Axe
First of all, you have to have a sword with you
and equipped on the Field. It doesn't matter what
kind of sword you use, it just needs to be a sword.
Second, go into the Forest and go down a level.
Keep going down until you see some grass. Cut it
down with your sword and walk down to the next level.
Next, walk to your right for a few steps and you
should see a chest. Open it up and you will
receive an Axe Shapestone!
Finally, go back to your house, go into the
Craftknight workshop (a.k.a., your room) and
create and Axe with the shapestone and one Iron
Ore. Now, you have an Axe! =)
