Collect 2 Well Stones and 2 Ambercorn and bring them back to Zarlman Two-Moons in Bloodhoof Village.
In order to pass through the Rite of Vision, you must gather the reagents needed to make the Water of the Seers.
I will need well stones, which can be found around the water wells in Mulgore. With those I will combine Ambercorn, which fall beneath the mighty trees in our land.
These reagents contain magical elements, and when brewed and consumed before the tribal fire, will cause you to encounter a vision. Follow it, and it will lead you to the next step of this holy quest.
