Dragons breath is only good to 1 shot the shrieker That's it It doesn't have tracking. This may sound like a noob answer but in a sword weilder and the thing i hate the most is when a rocket Flys past crota and then I inspect some one and they're using a fu'cking dragons breath... People who try to dismiss gjallarhorn in anyway are in denial that it's the strongest and most resourceful weapon in the game
