Trample (Ex; Str) As a full-round action, a creature with the trample ability can attempt to overrun any creature that is at least one size category smaller than itself. This works just like the overrun combat maneuver, but the trampling creature does not need to make a check, it merely has to move over opponents in its path. Targets of a trample take an amount of damage equal to the trampling creature’s slam damage + 1-1/2 times its Str modifier. Targets of a trample can make an attack of opportunity, but at a –4 penalty. If targets forgo an attack of opportunity, they can attempt to avoid the trampling creature and receive a Reflex save to take half damage. A trampling creature can only deal trampling damage to each target once per round, no matter how many times its movement takes it over a target creature.
Creatures with the overrun special attack receive a +4 bonus on combat maneuver checks made for and against overrun manuevers. Creatures with a trample attack are treated as if they possessed Improved Overrun.
