hey! I am making a sword art online build, and it is turning out great. however one thing stumps on each floor i build, and that is how am i going to implement a boss to my build? do i use command blocks? or perhaps a redstone contraption. or do i go to a mod? maybe it could be a quest for four items and just a build of the boss.... idk anybody have any ideas to implement bosses to my massive sword art online build?
