Unlimited arrows
Go to the Haunted Cathedral. Go to the pedestal where you are supposed to light the torches with fire arrows. Go through the passage that opens up, then go inside the building. Bring a piece of a statue with you. Once you are in there, throw the piece on the very edge of one of the tiles (the ones that trigger arrows when stepped on). Note: There might be only one tile that works. If done correctly, arrows will start shooting out of the wall and get stuck in a wooden pillar. You can collect as many arrows as desired. The arrows will not stop until you take piece of the statue off the tile.
