If you haven't heard there are some new forge world necrons out there. Check it out : achanthrites
From what I can tell they are do everything I wanted the Praetorian to do. with 3 wounds, a melta gun, a void blade, and toughness 5 I can't see why you would ever take the Praetorian. The only thing they lack is Reanimation protocols.
over all a nice addition. I think I will be geting me 9 of them so I can have 1 full squad >_<
last update of the day. I promise.
