i dont hear nothing about witchblade that makes her sound so damn bad ass her feats include............making pointy objects some that shoot out shooting energy healing making wings.
BUT..........the darkness in tales of the darkness holds fking stars in place
theres not really a gap. he's just more versatile but she can hang with him and could possibly beat him. They are more or less equals just that he can do more diverse things.
the witchblade itself or sara? Sara can't (hell i'm actually not even show how holding stars in place makes sense) but the witchblade might be capable of it. It depends on how it did it, if it was phsyical or energy based then yea, if it had some type of construct or something then no.
then obviosuly it cant do it by that method. Witchblade is more about augemtning and manipulating ones self, while darkness is like a green lantern ring only it effects darkness
