Prerequisites: Power Attack, Improved Unarmed Strike, Void Use, The Mountain Does Not Move, Fists of Iron, Breaking Blow

While under the effects of this kata you may make a single attack roll as if it were a touch attack. Your weapon is considered to be a +1 for the purpose of piercing damage resistance only. (If the weapon is already magical it can pierce damage resistance as if its bonus were +1 higher).

If you strike a flat-footed opponent with this attack, he must make a Fortitude save (DC 10 + your Constitution Modifier + half your level) or be stunned for 1d3 rounds.

The kata ends after the first attack roll regardless of whether or not you were successful in hitting the target.
