Mask of the Skull: This ivory mask has been fashioned into the likeness of a human skull. Once per day, after it has been worn for at least 1 hour, the mask can be loosed to fly from the wearer’s face. It travels up to 50 feet away from the wearer and attacks a target assigned to it. The grinning skull mask makes a touch attack against the target based on the wearer’s base attack bonus. If the attack succeeds, the target must make a DC 20 Fortitude save or be struck dead, as if affected by a finger of death spell. If the target succeeds on his saving throw, he nevertheless takes 3d6+13 points of damage. After attacking (whether successful or not), the mask flies back to its user. The mask has AC 16, 10 hit points, and hardness 6.
