Your charge impales opponents on your deadly horns.
Benefit: When you hit an opponent with a gore attack as part of a charge, you may also start a grapple as a free action. You do not provoke an attack of opportunity. Do not add your size modifier (if positive) to the initial CMB check made to start the grapple. Your size modifier applies as normal on all subsequent checks.
