Pandora Blade is inside a hidden room beside the Endu Shrine Gate Key chamber in the opening Crypt. Face the key table, check the wall to the right near the broken stone fixture and shrubs, then use Interact to open the concealed entrance.

Start at the right chamber

This route concerns the full-game Crypt on the Isle of Neasied. Use the Endu Shrine Gate Key pickup table as your landmark. If you have not reached it, follow the shrine key route before searching for the secret wall.

You need throwing daggers to operate the Crypt entrance switch on the approach. The hidden wall itself uses a different action. Do not spend your dagger charges shooting at every wall in the lower dungeon just because a ranged switch opened the outer entrance.

Open the hidden wall

Once you are in the key chamber, pause before leaving:

  1. Position yourself facing the central table where the named shrine key is found.
  2. Look to the right for the recessed wall section.
  3. Compare the broken stone fixture and the shrubs at its base with your position beside the table.
  4. Move close to that section and press your bound Interact control.
  5. Enter the newly revealed room and collect the sword.

The missing or broken wall fixture is a useful visual clue. The table, recess and plants together are more reliable than a direction alone, since “right” changes when you turn around. Reorient toward the table if the room’s layout no longer matches the instructions.

Confirm the pickup

The secret room is blue-lit and contains skeletons arranged in distinctive poses. Those are useful confirmation that you opened the intended passage, but the objective is still the weapon. Approach the sword on its plinth and check the displayed item name.

Open the inventory afterward and confirm Pandora Blade is present. Equip it through the equipment menu if you want to use it immediately. Then return to a Crystal Monument and save; finding an optional item does not replace the game’s manual saving routine.

If Interact does nothing

First confirm that you are beside the actual key table, not an upper room or another shrine-like platform. Move closer to the recessed section and try the interaction with the wall directly in front of you. Check your current key bindings if you are following an older guide that names a specific keyboard key.

Repeated sword attacks are not the documented opening action. Neither is activating the Crypt’s external diamond switch a second time. The entrance switch, shrine gate key and hidden wall are three separate interactions on the same broader opening route.

Is it required to continue?

Pandora Blade is an optional detour near a required pickup. If your immediate objective is unlocking movement, continue with the Shrine Guardian and Holy Sword Endu after saving the shrine key.

The weapon’s unusual upgrade ceiling is discussed in community guides, but this page does not rank it as the best weapon or promise a particular late-game damage result. The checked objective here is finding, collecting and identifying the hidden blade without mixing in an untested build recommendation.
