The Boars can be found on the Hunting Grounds and Highlands and appear in the ranges of 1-11.
Robust Boar:(1-4) Tough and aggressive packs of Elysian boars, that didn't seem to mind the cataclysmic rupture of the world that much. There is more mud now than ever, after all...
May drop Wooden Stick
Mad Razorback:(6-10) Alone, extremely aggressive and with a bite that can crush bones. Probably an alpha, having lost its supremacy over the flock... or gone berserk and slaughtered the flock members one by one.
May drop Mortalia Snake
