Bring 2 Felstalker Hooves to Canaga Earthcaller in the Valley of Trials.
The time is now, young [class]. You've grown strong and your spirit endures like the earth. Following the shaman's path shows you have wisdom before even proving yourself.
The element of earth will guide your destiny, becoming part of you if you are ready. But you must stand before the earth itself. If you are ready, then you will see things only shaman know of.
Seek out the Felstalkers to the north, and take from them two of their hooves. Return to me then, and we shall speak more of your future.
