Simply amazing! creating bosses cannot get any easier than this! The features are overwhelming and all of this in a simple to use gui. you won’t need tutorials for your boss creation which is great!
I love the integration of citizens (really fantastic if you want your boss to follow a certain path!!), the different means and ways you can spawn your bosses are more than convincing!
You may miss some features compared to mythic mobs when it comes to the actual abilities (although i believe nothing would stop you from creating new ones). But this is such a huge and complex plugin with many other great features that will definitely make up for it.
