Tazendra had shifted to the right arm to avoid the counter-attacks because, while she'd rather win than survive, she's not inclined to get hit just to make things dangerous. She's also aware that her life is even less her own that is usual when serving Her Majesty: if she dies and stays dead, her world (or possibly Penrose, or even both worlds) will be fed to the Calamity.

Still, she would love to follow Deadpool's example and hit the WEAPON until it stays down, regardless of it striking her back.

"Bah, well, let us reduce this thing to shards."

She cast another Shock and starting to hit the right arm. Currently it was focusing its attention on... something else, which had her watchful, but she saw no reason to not continue with what she was doing.
