The Count Lucanor (EP)

To unlock this trophy, you must have the crowbar and the butterfly in your inventory. Exit the throne room via the door behind the throne but you must equip the snake ring while you're in the throne room! If you don't, you will just be on the path to Wealth without answers.

Push the throne to the side and exit the castle. Follow the path back towards Hans' house but make a detour when you reach the big boulder and walk up. To the left of the graffiti is a grate. Use the crowbar to open it, then follow the linear path until you reach a sealed door. Use the butterfly with the sealed door to open it. Light the torches in this new room, read the plaque on the tomb, and raid the chests. Take your loot back home to Hans' mother and you will unlock this trophy.
