Elenwen getting her head chopped off.
I re-entered the embassy using a glitch. Walked up to her rooms and she was standing by her bed. Right when she was talking about how superior she was I lopped off her head with a dragon bone sword.
"WHO'S SUPERIOR NOW, BITCH?! YOU GOT YOUR HEAD LOPPED OFF, BY THE DRAGONBORN!"
I almost screamed that at my TV. I've had a dozen play throughs before that and always wanted to own and one-up her. My video game dream came true. And now I can pursue another one.
Another one was an epic scene.
I'm fighting Karstaag with Stalhrim armor for protection and he's still kicking my ass even with a fire enchanted weapon. I activate the special shout that you get in the dragonborn DLC.
Right when he flings me away I just stare at the screen like... "Yup, I'm gonna die." Then I hear this shout. I pan the camera and there is the ancient dragonborn kicking Karstaags ass. Went over to help and killed him.
I can't remember if I did a kill move or not on him. Nevertheless, most epic and best way to kill. Using the ancient dragonborn to save your butt.
