I have got to the last room in the Arbiter's Grounds and have used the spinner to turn cogs and hence turned the room walls and have revealed the spinner staircase in the room leading to the end of level boss. But I have missed the big key and I cannot get across to the chest or cannot use the spinner to move the walls to get to the room at the other end of the chest. Am I stuck indefinitely or can I A:use the spinner to move the cogs to open access to the other rooms? or is there a way of getting over he sand whirlpool across to the big key chest?
PLEASE HELP, 47 hours of play is at stake!!
