Anchoring (Greater)

This rune prevents enemies from escaping your grasp by Fleeing to other planes.

When you critically hit a target with a weapon with the anchoring rune, the weapon casts 8th-rank Planar Tether on the target (DC 38 will, counteract modifier ), except that if the target critically succeeds at its Will save, instead of having no effect, the dimensional anchor lasts for 1 round. When you hit a target with the weapon but don't critically hit, the target is affected by 4th-rank dimensional anchor for 1 round without a save (this still uses a counteract modifier of +28).
