This is just stupid. Im at the double barrier to zammorak and cannot get through. Tried everything. Killed jailer, killed everyting on the floor, offered bones at the altar to the side of the barrier and nothing. Also found a recipe for infernal sauce up there, whatever the heck that is. Found an infernal puzzle box near where I entered in a room by Sir Cadian
also missing one page, entry 14 cant find
also went through a several times
I see a red dot in a section you cant reach / but not sure if this is the missing page
