Thing is, if you’re trying to bite someone to death the neck is the most natural target (vs. bending down to take a chunk out of their stomach or trying to open the veins in the arms). The difficulty is more in actually getting in range, which realistically would get down to grappling in a fight.
I’d give it a flat 1HP, if that. Unless you get me in the neck, I doubt any human bite would take 25% of this commoners HP.
