This page of the Minecraft Dungeons walkthrough shows you how to unlock the arch paradise secret level.
This secret level took the longest to unlock due to random level generation. It took no less than twenty attempts to find the card unlocking the secret level. So don't lose hope and repeat the procedure indicated below until you find the item you are looking for. Note that we found this secret on Adventure difficulty.
To find the card that unlocks the secret level Arch Paradise, you need to explore the Pumpkin Patch level. Before reaching the ramparts, search the area to find a ship (pictures1and2).
