The boar is the ancestor of most pig breeds, being domesticated in China about 8,000 years ago, then spread throughout Eurasia in the millennia thereafter. The boar is more heavily built than the pig, with a muscular neck, well-developed canine teeth and an unusual aggression. This aggression gives the boar a +1 attack when in combat, increasing their natural THAC0 to 17.
Though found scattered through their environment, boars communicate through grunts and move along known areas in a familiar pattern, enabling boars to remain in contact as the group, or "sounder," moves through an environment. Sounders are female-dominated, made up mostly of female boars and their mothers. New territories are usually established by young females. Males tend to be solitary through the year, except during the breeding season, from November to January.
