The game is fun and all and most of the game didn't proved hard BUT THIS BOSS is so damn hard he hits like a truck and he stops between combos I genuin6was going to delete the game but stopped. I am losing my mind. I need help that is my build alright , I use maxed profand great sword with wolf knight set I have 38 str 22 dex and 25 end with 38 vig. I didn't completed the main campaign as only lothric prince and dlc remains, should I come later
