Boss walks the line of what's possible for cross-play servers, and that's what makes it so great. I get to put custom content on my survival experience that all players get to enjoy, and with SO many details. A must have for your cross-platform survival-like experience.

Thank you <3
I don't usually leave reviews on plugins, but for this one I got to make an exception - I expected SO much more from this plugin, really SO much more. For a 30 dollars plugin, I expected this to do miracles, instead I just found a average boss plugin at best. MythicMobs for example does so much more than Boss, on either premium or free version of it. Boss is just too limited and basic with it's features and capabilities. The fact the developer charges 30 (!!) dollars for this plugin is outrages, It's worth 8-10 at most. Support on discord is below average from what I saw and experienced, many questions are left unanswered as well. The comparison of Boss vs other bosses plugins here on this page is false, and in my opinion many of the things that are listed as a downside of other plugins are also applicable to this plugin as well. The plugin does have some neat features, such as the boss editor ingame, console errors being easy to read and find the cause of, and some other features that are indeed very nice, however these still don't justify charging 30 dollars for it. Do yourself a favor and stick with MythicMobs if you want really good and viable bosses for your server. If you are looking for very simple bosses, and are willing to pay an overpriced price, go with Boss.

Thanks for your review, I am sorry you found our plugin too easy/limited. Discord support is handled by moderators, if you need support from me directly simply open a ticket on GitHub at any time.

Based on what I heard from users, MythicMobs' scripting language is far too time consuming and complicated, at the end, most people only use about 10-20% of it which we accomplished via our menus so you can do the same in minutes, instead of weeks. Of course, if you like to code and debug your own scripts then just go and use MythicMobs, we have a 30-day money back on Boss which you could use.

But ease of access is the exact vision behind Boss, making everything editable via clean in-game GUI. I'll be happy to listen to specifically to which things are missing so we can add them on our roadmap, however you were not very specific in your review.

One tip I recommend, if you need custom pathfinders and AI, install Citizens. Boss will automatically hook into it when creating entities through it, and you will be able to access some of our most advanced features such as turning animals into aggressive mobs, changing their targeting etc etc. this way (in /boss menu > your Boss > Settings > Citizens).

Yes, this is a beautiful plugin that adds infinite creativity to how diverse the game world can be.
My favorite feature to the adding of new monsters is the drop tables you can put on them, it allows for some of the best gameplay if coupled with merchants/shops of some kind.

It is my favorite "Boss" plugin. Because it is very easy to use and at the same time an evolving plugin.
Best boss plugin by far, however, the support can be a bit better. Also a default generated config for bosses (to go off of)

Thanks, I am curious for what specifically you mean by "support can be better"? I was on holidays as announced and otherwise I am available during week days, feel free to email us or open a github ticket at any time. Sorry to hear that!

The boss config is not intended for user editing since we provide menu GUI for that, which is documented, and provides a few examples to make it easier.

I've used this plugin several times in past server setups. The customization is unreal, and it just seems to keep on getting better and better. Kangarko is an amazing developer, and I'm glad to have access to several of his amazing plugins.
A truly excellent plugin, with a huge amount of potential. While configuration is fairly complex, this is simple a byproduct of the crazy amount of flexibility it offers. Very impressed!

Thank you! Let me know how we can make configuration easier and I'll do it :)
