BOAR (WILD PIG)
A wild boar’s hide is covered with short, woolly, grayishblack hair. Along the spine, hair mixes with stiffer bristles to form a sort of mane. The average adult boar stands 3 feet high at the shoulder and measures roughly 4 feet long. Its formidable tusks protrude from its lower jaw and can grow up to 12 inches long.
Ferocity (Ex): A boar is so fiercely aggressive in combat that it continues fighting even when disabled or dying.
Scent (Ex): This ability allows a boar to detect approaching enemies, sniff out hidden foes, and track by sense of smell.
