do not use ashen idols. save them for fume knight. the idols near his location will heal him if he get close them. so first destroy the idols near him then you are free to use them for any idols you want.
Well save 2, what I did was used the 6 at the start and got the 4 from Brume tower and used them on the idols near fume
I don't have any more wedges and I need to destroy one more for the fume knight fight! What can I do now?
