If this ghost couldn't shadow walk as I could, the fight would be easier, but since he had that ability, I had problems with gaining any distance. I had my hands full with just parrying the attacks.
I tried to use the barriers to gain some advantage, squeezing putting a few of them in tight windows. I then did my best to avoid that place, before I build up some kind of small maze there. When It was ready I finally stepped inside. He was swinging widely, and heavily, so his blade crushed in some of my walls, breaking them into pieces.
They shattered easily, but what I needed was just a small window, and I got myself one. Just enough for one single thrust. I put all my might and technique into that, and the blade hit the target but slid off the skin like it was made out of diamonds.
