Discover Live Boss updating
One last feature that did not quite fit into the artwork above... Each time you change the Boss' settings, all monsters are updated automatically!
Is this plugin for me?
Below I have tried to enumerate many sticking points I personally met when I had a server with 30k unique players, and that this plugin will help you with.
Questions Before Purchase
I purchased Boss3 on Spigot, can I migrate?
Yes, we offer free upgrades to existing buyers, fill this form and we'll give you license on MCMarket free of charge.
Boss4 supports automatic upgrade from Boss3 with caveacts. Simply load your plugin over your existing Boss folder (back it up first!) and see the console for more info.
What mobs can be made Bosses?
Any spawnable entity in Minecraft from pigs to zombies to Ender Dragons, and if you have Citizens installed, even player NPC Bosses.
Will Boss work with MythicMobs or similar?
Yes! Boss has been reported and tested to work with another custom monsters plugins.
Can I make animals aggressive? Example: Chicken attacking players?
Yes! Since Boss 4, we support Citizens integration with custom pathfinders and goals. Even sounds and skins for player Bosses are customizable!
Is there a way to spawn the Boss without a spawn eggs?
Many ways! You can create spawn rules such as spawn Boss every Friday at 17:00 your local timezone, spawn Bosses naturally, replace vanilla mobs, or spawn Bosses when entering a region.
Also, you can spawn Bosses from placing eggs into a dispenser, or running "/boss spawn" command. You can even make a Command Block run this command to spawn them, or use our developer API to code in your own way.
Can I run a custom command when the Boss is spawned or dies?
Absolutely, under 2 minutes if you use our clean GUI, open your Boss > Settings > Commands window and configure.
Is it possible to let Bosses spawn if you enter a region?
Absolutely, under 3 minutes if you create a spawn rule using our GUI, type /boss menu and select Spawning to start. You can even force Bosses to stay within the same region!

Discover Live Boss updating
One last feature that did not quite fit into the artwork above... Each time you change the Boss' settings, all monsters are updated automatically!

Is this plugin for me?
Below I have tried to enumerate many sticking points I personally met when I had a server with 30k unique players, and that this plugin will help you with.
- Do you find the default Minecraft mobs boring and wished you could change them?
- Do you get bored killing the same mobs again and again?
- Do you have monster arena plugin on your server and wish to improve it dramatically?
- Have you ever had an idea of a monster dropping special key to unlock some part of your server?
- Do you players abandon your survival server after some time because they "seen it all"?
- Or generally if you feel like you're loosing players on your server, this plugin may help you gain it back.
- Be mindful about how you structure your gameplay and your worlds. Sometimes less is more.
- Install a minigame plugin that will keep player engaged while they are not playing.
- Consider having a multi-world plugin like Multiverse-Core that enables you to have multiple worlds
- Install a dynamic map like DynMap so you motivate players to track themselves in the worlds.
- Read the Spigot change-log often, try to understand the changes and update your Spigot accordingly (every second day at minimum on new Minecraft versions, otherwise once a week is in my opinion enough).
