Quest 37

Walkthrough

 * Talk to Nejiro in Megistris Castle (メギストリス城) on the third floor at D7.
 * Nejiro promises to give you the treasure inside a chest if you can dispel it somehow.
 * If you use the key item, it will give you a hint.
 * Travel to Verinard South (ヴェリナード領南) and slay a Crystal Hand (クリスタルハンド) around F1/G1. Once defeated, you'll receive a message that the box has been dispelled. (These monsters are the hands that are buried underground. Search the area carefully to encounter it.)
 * Return and speak to Nejiro to complete the quest. You can now open black treasure chests.
