Bonus Chapter: Fanelia
Use the following procedure to get the extremely powerful weapon, Fanelia, beneath the Bonus Chapter. When starting a new file, look at the bookshelf in the Magic Guild. You will get the Divine Scripture. It tells you where to get Fanelia. Defeat all the Accursed, then dig in the sand near Undine Spring five times. Only Ein can use Fanelia, and the move he performs is called Fanelia Beam. It is a very powerful attack with every hit fixed at 999 damage.
Excalibur
To get the Excalibur, get an "S" rank on Isher. You will get the Excalbur. Only Fia and Ein can use it. Fia will use Astral Glitter, a piercing Holy move, and Ein wil use Xandu, a powerful one-hit Holy move.
Fia: Banishment move
If you are in a tough battle and have a Rosary, get Fia to learn the move Banishment. When she uses it, many enemies may disappear. If it is not a practice battle, the Rosary will disappear. Also, Banishment does not work against Bosses.
Voice Collection
Do not get the mushroom book from Claude, but gather all three mushrooms in the Weise Forest of Nelde (select "Take") and give them to Reiche in the Grove of Repose after the Nelde chapter. This unlocks Voice Collection (Spiral Shell).
