I finally got the Emerald quest. I summoned the Idol, and when it didn't go to another room than the bedroom, I explored that room. Then only a curse was left in that room. Then, summoning a new Idol, it will never go to a room with a curse. So after a while, it only appeared in the bedroom (don't forget to remove the curse from the bedroom if the emerald doesn't drop.
I had the Idol 10 times in the bedroom yesterday and this morning, and the 10th time it dropped. Funny thing is, for the first 7 times I used a turtle of luck, and for the last 3 times, nothing special, not even an explorer friend.
This method will probably work with the Neptune quest too. Maybe there is a limit to the amount of rooms with a phenomenon, but as said, you can just banish them if you leave the curses alone (except for the bathroom in this case).
Took me 182 diamonds though, glad for the synthesizer.
