As a full-round action, you can expend one use of mythic power to attempt a sunder combat maneuver against each opponent within reach, selecting one item on each opponent to sunder. The damage from these sunder attempts ignores item hardness. If you destroy an item in this way, you drive the shattered pieces of the item into the flesh of its wearer or wielder, dealing 1d6 + a number of points equal to your tier of piercing damage. This damage bypasses all damage reduction.
