With a howling battle cry, your weapon crackles with energy. As you strike your foe, that energy detonates in a burst that scythes through those who stand against your cause.

When you use this strike, make a single melee attack. If you hit your opponent and his alignment has at least one component different from yours, a blast of divine energy originates from your attack's point of impact. The target of this strike takes an extra 8d6 points of damage and must succeed on a Fortitude save (DC 17 + your Cha modifier) or take a -2 penalty on attack rolls for 1 minute.

All of your opponents within a 30-foot-radius burst of the target creature must also succeed on a Fortitude save. Those who fail take 5d6 points of damage and take a -2 penalty on attack rolls for 1 minute. A successful save results in half damage and negates the attack penalty.

The target of the strike is subjected to both the strike's damage and the blast's damage, and must save against the latter.

The penalty caused by this strike does not stack with itself. Initiating this strike a second time before the previous use expires merely resets the duration of the penalty to one minute.
