Minthara also has mirror image, a spell that increases her AC and makes attacks less likely to hit. She usually pops that spell down pretty quick.
Also, there are traders in the goblin camp if they're not hostile yet. If you enter the courtyard outside, there's a goblin in the far left corner, assuming you're coming out from inside the fort. There's a tent and some goodies lying around where he hangs out, so you should be able to spot him easily enough. There's another one inside. Assuming you entered from the courtyard, head to the central room where you first encounter priestess Gut. Turn left, and follow a short flight of stairs up, and you'll see a halfling marching around a brazier. That's her.
