Yennefer had been prepared for there to be an attack on Ambrose, down at the bottom of the platform with her next wave of chaos ready. However, she doesn't exactly have a lot of time to react as the figure attacks Ambrose with a kind dark force that she doesn't think she has seen before, even from the most skilled of mages back on the continent. She also doesn't appear to be the only person stepping in to intervene, either, which is a relief.

She doesn't need to think on Ambrose, with two looming dark figures stepping between him and the attacker. Instead, she focuses her magic on the attack itself, even as a third figure comes into her focus, creating a kind of magical barrier that appears to deflect the attack, and Yennefer throws her own hands out to support it. Her magic pushes out from her towards the barrier, to try and redirect the force of the magic upward and away, acting as a second layer of magic to keep it from breaking through and pushing it outward. ​

With that out of the way, her focus comes back to the attacker, a figure she remembers seeing down in the cells. One of her hands lifts, her wrist rotating in such a way as to call her chaos back, concentrating it in a ball of light in her palm, preparing should he try that again.
