Sad but true... Smug archon: "Muahaha! Your biggy weapons cant hit me! *begins rolling dice for 5 unsaved wounds* Haha, passed this one! And that one, and that one, and that one, and... damn, a one! Oh well, I still got 2 wounds... what? Strength six weapon? Oh man." Feels like that everytime.
I must disagree with this guardian: usually, we would not be able to see the impacts in the scope of this picture. Whoever they are, those orks are among the finest marksmen I've ever seen among their kin.
Then I would have thrown some "shiny stuff" (i.e. plasma grenades) in the midst of the horde, and watched them rushing on it while grabbing pop-khornes
