You excel at moving foes right where you want them.
Prerequisites
Intelligence 13, Combat Expertise, Improved Reposition.
Benefit
When making a reposition combat maneuver, you can move an enemy into a trap or other hazardous area, such as a pit, wall scythe, or blade barrier. When you do so, the moved enemy is treated as though it had activated the trap or triggered the hazard, and it takes a –2 penalty to AC and on saving throws to mitigate the trap or hazard’s effects.
Normal
You cannot reposition a foe into an intrinsically dangerous space such as a pit or blade barrier.
