The servitor of a Lich lord always carry a wraith blade, usually a long sword but can be anything from a dagger to a great sword. Any attack with a wraith blade that hits on a natural 16+ does an additional (10) 3d6 cold damage. And must make a DC 10 Con save or be paralyzed for one minute. The target can attempt a saving throw at the end of each of its turns to end this effect.
