Qi Wave (3.5e Maneuver)

You strike the opponent in the sides in rapid succession, and suddenly the opponent's body grows weak and shudders...

Your attack strikes both body and soul, and sets up a vibration in the spirit which stuns your opponent's body. You attempt a concentration check as part of this maneuver, with the DC equal to 10 + the opponent's HD. You then make normal melee attack against a single foe. The attack is also part of this maneuver. If your concentration check succeeds, the opponent you gain a +4 bonus to attack and the opponent must make a Will save DC 14 + your Wisdom modifier, or become stunned for 1 round and then they are sickened for 1 round after. If your check fails, the attack is made at a -2 penalty, and deals normal damage.

This maneuver is a supernatural ability.
