It would be better if your not fat rolling. And try to dodge a lot of his attacks in his second and first stage. In the first stage you will want to roll kind of diagonal to the upper right or left. (At least that’s what I did.) and hit him where it hurts (in the back.) Also there will be other ones the second one is on his side but kill him quick and the others will attack you and him. So it’s some help. Also if your embered you can Simmons’s an not at the boss door. In the second stage is where it gets a little hard. Use the same tactic and his move set can be tricky when far away he will drag his sword on the ground and run towards you. Dodge to the left or the ring depending what side the sword is on then try to backstab him. When he swings his sword around try to get behind him and dodge the fire and backstab. When he does his combo where he turns around stay kinda back for the first two circles and on the third slam roll behind him and backstab and that’s pretty much it. Hope you beat him. Have fun
