You are able to guide your horse's attacks much more effectively than other mounted combatants are. When engaged in melee, your horse may rear and smash its fore-hooves down upon a target which is medium-sized or smaller.

Prerequisite(s): Mounted Combat

Benefit: As one of your attack actions for the round, you may order your horse or mount to rear and slam its hooves into a target that is adjacent to the horse. If the attack succeeds, it causes normal damage and the target must make a successful Strength check equal to the horse or mount's attack roll. If the Strength check fails, the target is knocked prone. If the Strength check succeeds, however, the horse or mount is unbalanced and the individual must immediately make a Riding check (DC 15) to remain mounted; in addition, the horse or mount may not move for the remainder of this round and may only move one-half it's normal movement in the following round.
