"This will allow you to hear the deceased."
The Rosary of Communication (called Rosary of Com. in-game) is a unique item in Onimusha: Warlords that allows its user to hear the thoughts of the dead. Once acquired, the the dead bodies seen in and around the Keep will have little clouds hovering over them, allowing the user to speak with them. The rosary can be found in the Keep Underground, past the demon library and in the room with the balance. Chop the rope on the left side to make a weight fall, raising the right side and revealing the Rosary of Communication.
