Dear all, I've closed the pit in Ancient Chambers, using the iron key that raise the platform... Is the Bracelet of Tirin lost or there's another way? Thank you in advance! No, you actually want to drop down the pit south of that. Sorry... I was a bit disoriented: I already have the bracelet in use...
