Screaming Amulet:
As an
attack action, the wearer can cause the amulet to emit a horrid psionic shriek that disrupts the brain waves of every living creature in a 15-foot-radius
burst centered on the wearer (the wearer is unaffected). The shriek deals 7d6 points of
damage, or half with a successful Will save (DC 17).
Power resistance applies. Using a screaming amulet does not provoke an
attack of opportunity. Activating the amulet costs 10
power points; if the wearer does not have 10
power points to spend, he or she cannot activate the item.
