I mean she'd throw in her lot with the group and also sell them goods but she'd ideally leave the fighting to the soldiers and such. In a pinch she can swing her sword and maybe take on an axe-grunt but don't expect her to be praying to the RNG Gods on a regular basis. 

Even in times of conflict there's a profit to be made and by dammit she'll make it on the backs of all your guys' efforts. She can even have support conversations because fuck it.
