You described the attack as more of an insult than anything else. And I specified that the mere step to the side was not sufficient to break her concentration. It does not say she is unable to defend herself at all when using it, only that she can not use other types of magic and should not be going ham and slashing through things left and right, ect. I also challenge how you say that he had leaped at her before the summons had finished as the new beings appeared just as she had finished her one step to the side.
