Kate:
A Battlefield
The healing spell does wonders for the soldiers fighting below. Some are clearly too far gone to recover (being cut clean in half is generally considered to be very bad for human health) but for the rest, it is a welcome break in the bad luck. The lightning following it feeds their newfound hope, the crackling chain ripping through daemons left and right. Each lets out a bloodcurdling howl for a second before destabilizing and collapsing back to wherever they came from. In a moment, only a handful remain, and they retreat after their injured brethren.
The soldier who cried out to you earlier is among the survivors. he waves you down, a look of thanks on his face.
