I used to bring Kee-Mo-Shi right up the gut, but she got killed too often, so now when I use her she brings up the rear. I've never used the Brunak combo though, I think I will try it. One way to get her into battle a little quicker would be to stay with Thorgrim (I think the original post mentioned this). Or send him in first and when he dies put him on Kee-Mo-Shi's card. I've had much success turning good characters into great characters with Thorgrim on the card. Be aware that common soulborgs negate all of your powers. And remember, you're never out of it if you've still got Kee-Mo-Shi.
Good shackling to you all, may the dice be with you!
