The problem however is touching the Witch-king, he has magic protection placed on him by Sauron to keep him from being harmed, as well as his our wraith invulnarabilty and armor. This combined with his great swordsman ship and flail makes me think he'd be hard to hit. I don't think the soul eating ability's would work on him becasue of the Magic placed on him specfically ment to keep his soul in the world.
