Painful Collision (Combat)

You shove your opponents into each other, causing painful and damaging collisions.

Prerequisite(s): Str 13, Improved Bull Rush, Power Attack.

Benefit(s): When you bull rush an enemy into another creature, both creatures take 1d6 points of bludgeoning damage, plus an additional 1d6 points of bludgeoning damage for every 5 feet your original target has moved as a result of your bull rush.

For instance, if you successfully bull rush a goblin 10 feet and it then collides with another goblin, both creatures would take 3d6 points of bludgeoning damage.
