First go to The blaze ruins and go to the third or forth floor, if your
at the top you are to far and should go back. Walk around on the floor
until you find a hole (there are many holes so it might take a while)
Fall into the hole. There should be three treasure chests. One holds an
old doll ,another has the map of the ruins, and the last should have a
naolin gold. Take the doll to the adventurers hut and talk to the owner.
You should get a necklace take it to the store next door. When you get
the next item take to the lottery store owner and you get the dowsing
stone. (only works if rumble is on).
