Prior staff

A tall device the height of an average man, wielded by Priors -- envoys of the Ori. They are adorned with the symbol of Origin. At the top is a blue crystal that glows when activated.

Prior staffs are still a mystery. Because the Priors that wield them are, in essence, hok'taurs, they themselves are capable of a great many things. The staff may serve as a simple ploy to lesser beings that the Ori are channeling miracles through the device, including resurrecting the dead, when the Prior himself may be making this happen, using the staff as but a light show while he carries out the "miracle" himself.
