A shaman is similar to a cleric in some aspects, but is more attuned to the world of spirits and animals. They are typically found amongst the less specialized races, like the barbarian Northmen, Iksar, ogres and trolls.
Other than the Northmen, who worship the Tribunal, most others follow the darker deities. While they have a solid repertoire of healing and other clerical type spells, the shaman's strengths lie in offensive and augmenting spells which can benefit others in their everyday lives. Many of the latter draw from the spiritual power of the animals with whom a shaman communes.
