Lol, so will the ork go to the dread magi for medical attention, to the mad chaos apothecary or just go with "Nah, didn' need dat arm anyway." ?
Well, he'll certainly need it reattached. Magic is hard enough to do with two arms, let alone one. Who gets to stick it back on, though... depends on who can do it first.
My Lucius post has been made, at long last. It even accounts for the effects of a ship suddenly appearing inside a Space Hulk at Warp velocity. That said, I don't think I've screwed anything up, so with that in mind, we can progress whenever possible.
