Ossian:
The only thing left now is the Rain Song Staff. Please defeat Barakiel, the Flame of Splendor, and retrieve the Rain Song Staff.
If you are not yet ready to go against Barakiel, go to the Valley of Saints, defeat the Wailing of Splendor, Fang of Splendor, Crown of Splendor, and Shout of Splendor, who are searching for the Rain Song Staff fragments, and bring 100 Staff Fragments from their corpses.
