Anyone knows the Witch's Towers quest keys number for normal and hard mode? I try to gather all keys but only get 9 for normal mode and 5 for hard mode and I am told that I have failed for gathering all the keys. I have even finished the normal mode for 3 times to confirm I have collected all the keys and it turn out to be still 9.
Pretty sure there's 10 keys total for every difficulty. Personally I've obtained 10 in normal mode, but haven't done hard mode.
