Ever wanted more bosses for your server?
EcoBosses allows you to make as many as you want,
without any coding knowledge required.

Set the drops, attacks, spawn in bonus enemises,
spawn them with a customisable totem - anything
you want to customise, you can.

And its not just attacks - sounds, immunities,
teleportation, boss bars, the list goes on.
So what are you waiting for? Make your own!

Why this plugin?

Built-in integrations for PlaceholderAPI, bStats, Oraxen, ShopGUI+,
NCP, AAC, Spartan, Vulcan, Matrix, CombatLogX, Towny, Lands,
FactionsUUID, Kingdoms, GriefPrevention, Worldguard, Head Database,
Multiverse, Essentials, ItemsAdder - the list goes on. Anything you have will work.

All our other plugins will work with it perfectly: you can use their items in
this plugin, and this plugins items in them - full custom item crafting support.
The full plugin ecosystem will lead to an experience your server has never seen:
take a look around play.ecomc.net to have a glimpse of what you can do with them.

All the items will instantly update using packets: leading to blazing fast performance,
no plugin conflicts, and no synchronization issues - it’s one step beyond the others.

And we haven’t forgotten the essentials. Full hex color / gradient support with every
format in use; MiniMessage support; support for reloading with PlugMan / PlugWoman;
automatic config updates so you never lose out on new options; and open-source.
