 Like clerics, shamans derive their spells from divine energy in general and from powerful entities; they propitiate spirits of an animistic religious system rather than deities, forces, or philosophies (although deities may also exist as extremely powerful spirits).These spirits embody the domains from which shamans gain powers and domain spells.A few domains are identical to clerical domains listed in the "Player's Handbook"; some are unique to the shaman and have no direct equivalent to any clerical domain.
