This weapon emits a low hum that sounds distinctly like a chorus chanting slowly.

On a critical hit against an evil creature, a heavenly burst weapon discharges a shower of radiance that deals 3d6 points of damage to the target and blinds it for 1 round. A successful DC 14 Fortitude save negates the blindness.
Projectile weapons bestow this property upon their ammunition.
