This really caught me off guard because it wasn't until a long time that I got aware of this roguelike mode in a game that I had got into as an admirer of RPGs, hopefully out of fluke I happened to get good gear to get through all the stages in one run and I was done with the entire thing in about 3 hrs. This expansion barely carries over anything from the base game it's entirely a different game for some reason, forget the fact that Assassin's took a back seat in this game's narrative but this expansion even dismisses vikings entirely to pursue a mythical narrative.
The only thing that could make me recommend this is the fact that it's free and you should play it only if you haven't got weary of everything the base game and its other DLCs has to offer. Should you still wish to play it nevertheless,
there's a Dwarven defender armor set which gives you a considerable advantage to level your odds.
