In my experience, a shaman would typically communicate with spirits, revered ancestors or some other kind of otherworldly beings, and getting aid from them in exchange for sacrifices.

Either that or drop totems and outclass most DPS.

Shamans are a catchall term for Animalism base priesthood really. It wildly varies from region to region. Sprits to take center part most of the time though, and ancestry does play a big part in things. A slavic Shaman might be called a Koldun by the way.

Your magic is bound by contract. Your primarey source of magic would be whatever your Patron being lends you. Often if not always for a price. Other then that, just general ceremonial stuff. Slavic Sorcery and Germanic Sorcery is the main inspiration to most popularized Witchcraft stuff in media after all.
