Thanks very much for all the replies. Super helpful.

My first experience with her in battle at Moonrise Tower she was super unhelpful. I was planning to chuck a backpack nuke right in the midst of the enemy, but then she just charges right into them. Not content with that, she then cast ice storm on her own position and killed herself.

But I'll definitely take her when I get to the city. I think I'll just bump her Dex, give her a long bow and make her a healer. A healer with ice storm.

Thanks again everyone.
