Can Dark Shroud be used to debuff models that are knocked down? DS reads that if affects models within its melee range, but the KD rule states that something that is knocked down can't be in anything's melee range. Is this possible? Can I really knock down something and suddenly be unable to hurt it with my axe because DS mysteriously didn't do it's job? Will other models similarly not be able to benefit from the debuff for that same reason?
