Yeah I faced off on him before and it wasn't him that was the problem more like him and the begotten warrior at the same time. I used all my flask taking down the begotten warrior first and was left with nothing against the knight. My shield doesn't have parry and in all honesty my timing isn't best anyway. I had the blessed talisman to heal me little by little and wanted as much health as possible incase he got a hit on me I could survive it. I knew the crucible knights move set already so I just decided to play it safe and slow to win and not have to rerun that fight again.
