On the [lore]Bear Form[/lore] page it describes the feat thus, "At first level, a Bear Warrior can transform himself into a Black Bear 1x/day. At fourth level, he can become a Grizzly Bear 2x/day, and at eighth level he can take the
fiercesome form of a Dire Bear as many as 3x/day."
Fiercesome is not a word that I can find in the dictionary. I believe the word that the sentence calls for is
fearsome.
