ELDEN RING Shadow of the Erdtree Putrescent Knight complete fight

Putrescent Knight is at the bottom of the Fissure found in the south at the very bottom of the map.
Interesting thing, I beat the boss and then he almost killed me with a spell he cast before I killed him. I used blasphemous blade +10.Gaius armor, Scadutree blessings 14, Revered ashes 8 at the time of fight.
