Elder Mountain Hammer

You draw strength from the earth beneath your feet
and transfer it into ruinous power. Your next attack
drops like an avalanche upon your foe, hammering
him into submission.
When you use this maneuver, you make a single
melee attack. That attack deals an extra 6d6
points of damage and automatically overcomes
damage reduction and hardness. You may use
this maneuver to make a Sunder attempt. Doing
so does not provoke an attack of opportunity.
