Living animals are greatly disturbed by your chilling presence.
Prerequisite: Con -
Benefit: When an animal or its rider is the subject of a charge or attack by a mount with this feat, it must make a Will save (DC 10 + 1/2 mount's HD + mount's Charisma modifier). If the saving throw fails, the animal suffers a -2 morale penalty on attack rolls, damage rolls, and saving throws as long as the mount is within 30 ft.
