I have read a few posts that this game is too hard etc. I did not find that true at all. I played through blind the first time and dont think anyone had died. Before I even knew the fights. I was thinking it a bit easy.
Also, using grease spells or fog or fire or high ground or back stabbing is not "cheese" they are core game mechanics.
I think maybe a lot of players are new to this type of game and have not figured out how to play yet.
did you know food is as good as a healing potion? and only take a bonus action? Yeah you can attack AND heal, every turn? How are you dying?
The Red CAPS are easy cause you are given a turn or two to prepare for their attack and they don't all attack at once.
If you are having issues with difficulty I suggest looking at some of the videos and see how people are playing and getting ideas.
