Disrupting [Property]

In addition to dealing its normal damage, a projectile from a disrupting siege weapon can destroy undead creatures within 60 feet of the impact. Treat this effect as if the projectile had performed a turning check as a 5th-level cleric (the projectile has no Charisma modifier). Undead that would be turned by the check are unaffected, but any undead that would be destroyed by the check are destroyed. Undead closest to the impact spot are affected first.

Prerequisites: Craft Magic Arms and Armor, ability to turn undead.

Cost to Create: Varies.
