This weapon is pierced with numerous tiny holes in a decorative pattern. These holes produce a whistling sound when air moves through them.

Upon command, this weapon begins to vibrate gently, though it emits no actual sound in this mode. Whenever an activated screaming weapon hits, it produces a high-pitched sound and deals an extra 1d4 points of sonic damage to the target. This noise is unpleasant, but it has no adverse effect upon any creatures other than the one struck. The ability of a screaming weapon to deal extra sonic damage is negated in any area of magical silence. Screaming weapons have no additional adverse effect on creatures with unusually acute hearing, although such creatures tend to dislike them.
Projectile weapons bestow this property upon their ammunition.

Prerequisites: Craft Magic Arms and Armor, shout or sound burst.
Cost to Create: 1,000 gp (plus 300 gp for base item), 80 XP, 2 days.
