An invisible barrier holds back vermin. A vermin with less than one-third the character's level in HD cannot penetrate the barrier. A vermin with at least one-third the character's level in HD can penetrate the barrier if it succeeds at a Will save. Even so, crossing the barrier deals the vermin 2d6 points of damage, and pressing against the barrier causes pain, which deters less aggressive vermin.
