Anchoring

This special ability can only be added to a melee weapon or a thrown weapon. An anchoring weapon pins a target in place and prevents it from moving. As a swift action, the weapon can be fixed in place in a point in space, functioning as an immovable rod. This ability can also be used when the wielder hits a creature with a melee attack using an anchoring weapon. This anchors the target to the weapon, preventing it from moving away from the weapon. The target is not entangled or paralyzed; it simply cannot move from its location without first destroying the weapon or making a successful DC 30 Strength check as a full-round action to move with the weapon up to 10 feet. An anchoring weapon remains motionless and cannot be used to attack while it is anchoring a creature. An anchoring weapon has no effect on amorphous creatures, including elementals, oozes, and creatures in gaseous or liquid form. It also cannot anchor incorporeal creatures unless the weapon also has the ghost touch special ability.
