As they explore the labyrinthine Proving Grounds, our heroes will encounter unusual machinery blocking their path. To get through, you must press switches that cause the runestones to switch lanes from left to middle to right and vice versa. The middle lane switch moves all three stones, while the left lane switch moves the middle stone, and the right lane switch moves the bottom stone.
