I play a level 20 cloth assassin on master difficaulty. I am not the best at staying undetected and so I figure that this is the perfect way to learn, any of the ash spawn can one hit me.
10 invisibility potions and no deaths later I finally cleared the first fort. This made me really aprichiate the difficulty though.
I Actually feel a sence of achievement knowing that I was able to complete it. This is something I wish the whole game had and it really made me love this dlc even more.
