Even the less intelligent races of the Old World have some magical ability, although their knowledge of the subject is primitive and half-formed. Certain Ogres, Orcs, and Goblins can cast spells, but, for all three races, magic it tied to religious, shamanistic practices. Orcs and Goblins use shamans to channel the peculiar energy that they call the Waaagh!, unique to their species, to create spells and magical effects which can have surprisingly devastating results, including the spectacular explosion of the shaman's head.
