Crushing Weight of the Mountain p. 82
You crush your opponent beneath you, squeezing the life out of him as you pin him to the ground.
Engaging in close combat against you is, at best, a foolish prospect. Drawing on your understanding of the Stone Dragon discipline, you squeeze a foe within your grasp and force the life from him.
While you are in this stance, you gain the ability to constrict for 2d6 points of damage +1-1/2 times your Str bonus (if any). You can constrict an opponent that you grapple by making a successful grapple check.
