Shamanism is often confused with druidism to those unfamiliar with either, but they are quite different in nature. While druidism offers mortals power in the form of contracts with the mystical fey of the wild, shamans gain power through a symbiotic relationship with ghosts and spirits who are meant to guide and protect them. A mortal can form a partnership with, or have a partnership formed for him, between himself and a spirit. This spirit slowly saps manna from the mortal in exchange for guidance, insight into the goings on of the spiritual plane, and sometimes direct influence over the material realm. The powers that spirits control within the material plane are varied and are often limited only by what their mortal partners can think to ask of them and their own inclination to do so. Spirits do, however, vary in strength and their strength can grow or diminish in various circumstances. Another key issue to partnership with a spirit is that all of the actions it takes to affect the mortal realm require manna. A spirit has no manna of its own nor can it regain lost manna. Should much be asked of the spirit over a short period of time and it run low on manna it can take what it needs from its partner immediately. This is, however, a painful process for the same reasons a god collecting from one of its True Priests is painful. Spirits require at least some small amount of manna to keep itself tied to the mortal plane. Should it ever completely exhaust its supply it will not have the strength necessary to remain tethered to the living realm and will be sent to the Cold Docks by an Undertaker to begin The Journey.
