Since the Imperial's ward was already up, Sabine's icicle was absorbed by it. However, between that and the blizzard, it was being stressed to its limits. As such, the Imperial had never stopped charging forward. She knew Sabine to be the superior mage; her blizzard had been enough proof of that. So, she was going to try a different tactic. While maintaining her ward as best as she could, the Imperial conjured a bound mace in her hand just before reaching Sabine, then swung sideways for her center mass to try and guarantee a hit. 

The last of the hunters still trying to resist were caught between werewolves on one side, Malithus and Arthon on another, Shurgrag's fireballs, and Fendros' arrows. Being the thoroughly hopeless fight that it was, two of them panicked and dropped their weapons, while the last tried to run off in the most empty direction he could find. The Imperial fighting Sabine was essentially guaranteed to lose, but Sabine would need to protect herself for the next few seconds.
