I asked this question shortly after Dragonborn DLC was released on XBOX... wasn't available for PC at the time. So, thought I would ask again.
I have been playing video games for a long time, and I have developed a habit of conserving the big guns for when I really, really need them. It seems to me that in the past, they gave you the big gun because you were going to need it, so don't waste it too soon! I have never really been able to overcome that notion. I end up saving the best ammo, the best weapons, etc. basically forever.
Karstaag is just about the only thing in Skyrim that falls into that category for me. I fall into the last category. I want to use him, but I know I probably won't.
What about you? Please share stories of your epic battles using Karstaag!
