"Ah, i see you have proven yourself to Zand and he wishes to see more of your prowess. go to the Tower of Kurn and bring him the Skulls of the Caste of Bone Brethren, a caste of powerful shamans who perished fighting undead in the Field of Bone several decades ago."

"The temple shall be pleased. As instructed by the Hierophants, here is your Iron Cudgel of the Mystic. You have done well that I must ask you to [collect the Crusaders of Rok Nilok]. Take this chest. Inside you shall combine the skull of their leader and at least five of the caste members. You then will go to the Swamp Garrison and deliver the full chest and your Iron Cudgel of the Mystic to Mystic Dovan. Go to him now and inquire of the Crusaders of Rok Nolok."
