Learn how to dig for treasure in the Grand Underground in pokemon brilliant diamond and shining pearl using the Explorer Kit, Sledgehammer, and Pickax.

To start digging in the Grand Underground in pokemon brilliant diamond and shining pearl, you first need access to the Grand Underground itself, which requires the Explorer’s Kit.

  • Explorer’s Kit (obtained from the house to the right of the Pokémon Center in Eterna City).
Walkthrough
  1. 1
    Use the Explorer Kit. A hole will appear underneath you, and you will fall into the Grand Underground. The Explorer Kit is stored in the Key Items section of your bag and allows instant travel to the Grand Underground from almost anywhere. The location where you use the kit determines your starting point in the Grand Underground, but using it again always returns you to your original location.
  2. 2
    Once in the Grand Underground, look for small orange sparkles on the minimap. These indicate areas where you can dig for treasure.
  3. 3
    Approach a wall with sparkles and choose to dig. A puzzle screen will appear, showing how many treasures are available in that section of the wall.
  4. 4
    Use the Sledgehammer and the Pickax to break away pieces of the wall to reveal hidden treasures. There is a limit to how many times you can dig before the wall collapses and you are forced to leave.
  5. 5
    The Sledgehammer clears a wider area but causes the wall to collapse more. The Pickax works on a smaller area but causes less damage to the wall.
  6. 6
    You can swap tools by pressing the R button or tapping the touch screen.
  7. 7
    To obtain a treasure, it must be fully uncovered, with no rocks obscuring it.
  8. 8
    Once all treasure is recovered or the wall reaches its limit, you will receive all the treasure you recovered.
