The Oracle Bone is a Charm acquired in Gothica. In either the Ivor Tower or Ebon Keep market, the player can trade for it with a Jeweled Scarab or a Golden Jackal.

The Oracle Bone purportedly causes some NPCs to say additional dialogue. However, only one confirmed instance of this occurs in the game - the alchemist beneath the Chessboard, on the path with the Energy Core on it, will give the player the Stop formula if they have the Bone. Any other instances of the Oracle Bone affecting NPC dialogue are unconfirmed.
