You can attempt to reposition a foe to a different location as a standard action. You can only reposition an opponent that is no more than one size category larger than you.
A reposition attempts to force a foe to move to a different position in relation to your location without doing any harm. If you do not have the Improved Reposition feat or a similar ability, attempting to reposition a foe provokes an attack of opportunity from the target of your maneuver.
You cannot use this maneuver to move a foe into a space that is intrinsically dangerous, such as a pit or wall of fire.
If your attack is successful, you may move your target 5 feet to a new location. For every 5 by which your attack exceeds your opponent’s CMD, you can move the target an additional 5 feet. The target must remain within your reach at all times during this movement, except for the final 5 feet of movement, which can be to a space adjacent to your reach.
An enemy being moved by a reposition does not provoke an attack of opportunity because of the movement unless you possess the Greater Reposition feat.
You cannot move a creature into a square that is occupied by a solid object or obstacle.
