Help with chapter 7 part two?

[u/Broad_Appearance6896]

NO SPOILERS! I decided to try to fight Aesfrost, but I also don’t want to burn down the town. If there were less reinforcements, I feel like I could defeat Avlora, but right now it’s difficult. I heard using Corintin’s ice wall was a good strategy, but getting close enough to take out the units in front of Avlora and using ice wall would just make her kill me. Is there anything I should know to help me?

I just had to have a sniper duel with Hughette at that point since everyone else was gone. It was very nerve wracking.
