The world around you is filled with spirits, not only in living things, but in the elements that comprise the world. Unlike the Druids, who call to the spirits and ask for their aid, you bond with spirits directly, drawing on their power and in turn strengthening them. You do this by forming an Effigy that represents those spirits. This Effigy forms the bond between you and the spirits, and with it you manifest their power.
As a Shaman you will create an Effigy that helps you bond with the world around you. If you choose to be an Animal Shaman, you create an Effigy that evokes a particular kind of animal. If you choose to be an Elemental Shaman, you create an Effigy that helps you talk directly to the elements and elemental spirits. Some ancient tales speak of Shamans that called to their ancestors, but if that was ever true the ancestor spirits have been long silent.
You create an Effigy through the clothes you wear and the tokens you carry and display. It is not enough to hear and see and feel the spirits; you must become a physical representation of the spirits you call upon. Your look helps you bond with the spirits and draw power from them.
