Passing of the Spirit (3.5e Maneuver)

The undead are pale mockeries of life, and your blows seek to push out the negative energy powering them with a rush of positive force.

Your weapons glow with an awesome power, its positive might tells you to reach out and smite undead! When you use this maneuver, you make a melee attack against a single undead foe. The attack automatically overcomes any damage reduction, and the target must make a Will saving throw DC 15 + your Wisdom modifier, or be destroyed. On a successful saving throw, they still take normal damage. If a non-undead is hit by this attack, your attack still overcomes any damage reduction and deals normal damage, but there is no saving throw against destruction.

This maneuver is a supernatural ability.
