Powerful Charge (Ex): A female hoardevil typically begins a battle by charging at an opponent and making a slam attack with her bony chest. In addition to the normal benefits and hazards of a charge, this tactic allows her to make a single slam attack that deals 2d8+7 points of damage.

Skills: A hoardevil has a +4 racial bonus on Jump and Listen checks.

A hoardevil usually attacks with a vicious bite. It also can make a slam attack with its chestplate, but it cannot deliver both attacks during the same round.

Like a male hoardevil, a female usually begins a battle by using her powerful charge ability to slam the opponent with her bony chestplate. Since the female can fly, however, she often uses the withdraw action to fly away, then swoop down to make another powerful charge.
