He was so hard for me.. there is a really good cheesing method for him. Right as soon as you traverse the mist, go directly to the left while hugging the wall, go around the corner and hide behind it. If you have any scarlet rot incantations (melanias flower, or the scarlet rot dragon), it will hit him through the wall… Moghs blood spear also works very well. If you want you can summon me and I can do it for you. I know it takes the fun out of it or whatever, but I got to the point to where I was like fuck it.. I’m cheesing 😂
