There is a cure to the miasma that has been plaguing the Basin. In order
to help destroy one of the miasma rooms, the steps are:

1. Go to the glimmering crystal sphere on the path to Snow Valley
in the Avechna Teeth Mountains.
2. Touch the crystal sphere and receive a feather
3. Touch the feather which will turn into a statuette if a diamond is
in the room. If there is no diamond in the room, the feather will
glow if it is close. The closer you are, the stronger the glow. If there
is no glow, then there is no diamond in the area.
4. If you have a statuette, go to a room with a miasma in it and drop it.
The miasma cannot be broken into two so some miasma rooms will
not be able to be cleared.

Do not let the miasma travel to the room with the crystal sphere because
BAD things will happen! Be strategic with how to clear the rooms.

You can do this quest once per game month. The quest will be able to be
performed throughout the month of October. If you perform the quest 21x,
you will receive a special, permanent artifact! You can check your
status with QUESTEVENT.
