Perform the Rite of the Moon at the moonwells scattered around the world. You can find them in Ashenvale, Felwood, Feralas, Moonglade, Stonetalon Mountains, Duskwood, and Mount Hyjal.
If you let the Blessing of the Moon expire, you will have to start over.
My staff has served me well for many years. It has stood by my side, been through many trials... and as I grow older I find myself leaning on it more and more.
Its flowers bloom every Lunar Festival, basking in the Elune's might. They bring me so much joy, I wish for them to stay all year long. I know a way... but my bones are too old to make the trip.
Perhaps you would take the journey for me? Empower my staff in the light of the moon at the moonwells around the world. Then my flowers can stay.
