Card 41 is a card that depicts a torch.
Location[]
The torch card can be found in the Underground Labyrinth. You can find it in a warp located at the top left of the map that you need the swap to access. From here, solve the puzzles to advance eastwards until you reach a room with a chest. The chest contains this card. Alternatively, you can skip the puzzles by swapping the exact correct tile to enter the room which holds the chest, at the bottom of the map (see screenshot for exact tile to swap).
Block to swap to easily get to Card 41.
