Hahahaha! 
I like to be the good guy, but in POTD I can just be only Diplomatic / Honest. 
My 2 bleak walkers perform as dps snipers, so I don't care about their defenses very much. 
I was worried about my MC defenses, the shieldbearer. He will be my tank. I will proceed then. 
Thank you very much for the info!
