- This diagram is located in Mont Crane Castle. Enter the courtyard and head left. Use the magic lamp on the wall to reveal a secret entrance. Move along and obtain the crystal from the table. There is a switch near the bookshelf in the next room, activate it and dispatch the enemies that arrive. Afterwards use the crystal to activate the portal, where you will face a golem. Defeat it and inspect the containers at the end of the room to find the diagrams for this, the Grandmaster Griffin Silver Sword and the Grandmaster Griffin Armor.
