The shield she had cast just before beginning her chocolate frog was set to reflect the damage. She liked that sort of shield best, finding it kept the opponent busy while she added extra work to their load.

In fact, it didn't disappoint her that the sardines were dodged as they were simply a lesson in not casting anything you wouldn't want thrown back at you. Those elf like ears she was trying to throw at her?...No thanks. Lex didn't much fancy being thrown off her feet either. What DID disappoint her however, was the girls like of intuition and tactical thinking. The Auror had cast a shield charm while the girl busily dodged sardines, yet she chose to send direct attacks at her anyway. Did she think the shield would break? Didn't she figure an Auror knew how to defend against much stronger artillery out in the field? It was a wasted effort at most and it left Alexa shaking her head as she watched the magic bounce back.

Disillusioning would have been better advised. Creating cover. Becoming elusive and forcing her into the next move first. All much better ideas than aiming at a shield that was already in place.

Quite suddenly, it all seemed to vanish--the shield and the Auror. With a non-verbal featherlight charm in place to cushion her steps, Lex moved about, casting a daydream charm around their little dueling area. The daydream looked much like reality. In fact, the only thing off about the daydream was that four Alexa's now stood at equal distances surrounding the Seventh Year. The arena looked the same, giving away no signs of replication or tampering but each Alexa looked just like the other.

With full command of the daydream, Lex remained disilluioned and a small ways off where she could better observe and wait for the right opening. Her selves took aim, casting what appeared to be bombarda and confringo at separate intervals and with varying degrees of intensity in rapid succession. There was a 5th pretend Alexa, she was as disillusioned as her original and also crept about the room waiting.

It was all about timing. Your move kid.
