Paralyze Limbs (3.5e Maneuver)

You disrupt the continuity of the target's soul in their legs/wings/whatever, and they find that they can't move.

Make a normal melee attack. If it hits, the target becomes immobilized for 1 round/level. The target may make a Will save at the beginning of each of its turns to end the immobilization early.

This maneuver is supernatural.
