Karuda:
We can help the Spiteful Souls in the Crypts of Disgrace to become "saved" before they travel elsewhere. When you defeat the Spiteful Souls, you will see some Cursed Grave Accessories which they used to manifest their physical power. Please these accessories them and bring them to me.
By my current estimate, I need about 180 of them. If you get me that many, I think I can do the rest.
