Instructions
Walk onto the platform with the green switch and step on it to open a new pathway to the next platform. Step on the next green switch and the pathway to the next area will be clear.
Walk up to the blue switch (it will be the only one you can reach) and activate it three times. Walk to the blue switch on the left that is now accessible and activate it. Activate the green switch which you are now able to reach in order to clear a path to the doorway on the right. Exit through the doorway to reach the third and final part of the maze.
Activate the red button on the right of the room, then the one to the left. This opens up a pathway to the bridge, so cross it and activate the green button that is now accessible three times.
Follow the path to the blue button and activate it until you can access the way to the ledge on the north. Cross over, then turn right and walk down. Keep going until you reach the platform on the bottom right with the red switch.
Follow the path back up to the top of the room, where the ledge leading to Volkner is now clear. Walk over it to reach him and start the battle.
