Aura knowing she is better at range rather than risking being up close and personal is going to hold the line (DC 10) as well as using Hawk to gather infomation Aka keeping the bird sweeping over the battle feild to communicate and changes in position or numbers. Maybe any immediate weaknesses as well. She will use there telepathic link and his sight rather than her own to communicate and then speak through the bird to people on the battle feild, specifically Jormund if he is going to be in the front lines. Maybe that will help him out a bit.
