I am testing around with the inactive interactions gameshark code on and found something very interesting, apparently, the doors to the Chamber of Holding are unlocked by default and the only things blocking you are the guards and Saul. If anyone can figure out how to go around Saul to enter the Chamber of Holding early, it would help us save some time for the speedrun! (We still have to get the Staff of Ages to complete the speedrun, but we theoretically skip having to give the pendant to Saul).
