Forced Movement

When forcing a creature to move, if the creature encounters a solid, impenetrable barrier (most commonly a wall), you may attempt to force the creature into that wall. This forced movement is considered hindering terrain and as such, allows a save. On a save, the creature falls prone in the last square before the obstacle. On a failed save, the creature falls prone and suffers 1d6 points of damage from hitting the solid object.
