Seren shook her head. "A-actually, I can make them strong enough to stop your attacks," said Seren, trying to stop any misunderstandings, "but then the number I can summon goes down." She shuffled he feet as she thought of what to say next. "And another problem is I can't make them float or anything. I can just summon them somewhere in front of the target right before they get hit. If I don't get the timing right, the shields fall down and whatever's behind it gets hit." That was the main reason she had come. As it was, her shields were near useless in protecting anyone but her.
