So in my current playthrough, I'm playing as a surviving member of house durrandon and I'm taking back the storm lands. I was able to capture Stannis pretty easily and kill him. But now I have fought with Renly 3 times, and 3 times he has escaped afterwards. Im curious if maybe its not possible to kill both Renly and Stannis? Or does Renly have plot armor?

I'll keep attempting and update this post if im able to complete my task. But if you have any information on this it would be great if you replied!

Thanks!
