Hey guys,
This is an important fight it seems and for many of us a frustrating one. Just to let you all know it is possible to do it.
I thought I'd let you know what I did just to help those people who are still having a tough time.
Well, here it goes, don't pay attention to this if you don't want me to spoil it for you.
First, get to level 13 at least and put some points in dex, I tried to do it before level 13 and could not. It helps to have your creature and your ghost with you, mine is about a level 3 ghost. You should line up close by, so you can rush in, you probably would do this on instinct, and will get killed when your a low level, do it again. This way, you get an arrow hit around 150+ and can heal up, using potions or if you want your ghost (doesn't work great all the time). You should heal right after you get that arrow because it hits a good one lol. You just hit him and he may make you run around, but it is only stunning you really, you really aren't running around for some reason, if you are that close to him. Now, just melee him and have your ghost and potions ready for healing, you should be fine.
