Well because technically a person with no Attacks can't use the Sword Of Rhun so yeah. But okay if it is in the faq that works for me.
The character technically does not have his own attacks but the rules deal with the profiles provided in individual rule books. The 6th edition Lizardman rulebook specifically states that the attack on the Slann's profile is delivered from a Skink Attendant perched behind him. Like the above post says, the skink gets the sword.
