Yeah, I just practiced my parrying for the longest time on the black knights that are lined up at the kiln. I'm not perfect at it, but I managed to land a parry 8.5 times out of 10. After doing some weapon upgrading and kinda getting the hang of Gwyn's patterns I was able to parry his quick attacks. Took like 3 or so parries to take him down. I played a little bit of NG+ and now I must slumber.
Undertaker and Dean Ambrose = the greatest
Deal with it, nerds.
