Quivering Soul (3.5e Maneuver)

''Your blow seems to punch deep into your opponent, and drag out a glowing phantom mist which vanishes moments after. The enemy's life is now in your hands.''

You reach out and grab your opponent's animating force, ripping it from its body but leaving a single invisible thread which you can snap at a moment's notice. The enemy is now at your mercy. When you initiate this maneuver, you make a normal melee attack. In addition to the damage from the attack, the opponent must make a Will save DC 17 + your Wisdom modifier, or have its soul sundered. At any time during the duration of this maneuver, you may sever its soul (a free action), killing the creature. The enemy is aware of the power you currently hold over it. A successful saving throw negates the death-effect, but not the damage.

Creatures without a constitution score are immune to this ability, and simply take normal damage from the attack. You may only have one quivering soul in effect at one time. If you make another successful quivering soul attack while another one is currently in place, the first one expires.

This maneuver is a supernatural ability.
