Good idea or bad idea, I want to make the final boss of my DW campaign as difficult as I can since my group has beaten every challenge in their path. Should I make the boss have its own class and literally play the monster itself as my own character? They seem to push through every obstacle I place in front of them so quickly and without any true challenge 😑
