Newer MythicMobs features require Spigot 1.8 to work and will continue supporting Spigot going forward. MythicMobs will also be ported over to Sponge once it is stable.

What is MythicMobs?

MythicMobs allows server administrators to create custom variants of mobs.

These variants can include:

  • Mob Skills: Giving mobs custom skills with powerful conditionals and delays, based on a robust system of triggers and/or timers
  • Mob Attributes: Modifying all mob attributes such as health, damage, speed, follow and combat range
  • Special Effects: Allowing mobs to use custom sounds, particles, and special effects
  • Equipment: Setting equipment and creating custom items with attributes and drop tables.
  • Damage Modifiers: Change how damage affects mobs so they can be immune to drowning, take half damage from arrows, be healed by fire, etc.
  • Mob Spawners: Creating powerful custom Mob Spawners to spawn your Mythic Mobs at specific locations, with optional timers, conditions, attributes, cooldowns, etc!
  • Spawning Control: Set your custom mobs and bosses up to spawn randomly in different areas of the world, based on any number of conditions you can specify. You can replace natural spawns completely!
  • Mob Levels: Allow mobs to scale in level and increase in power based on where and how they spawned, having scaled health, damage, and more abilities as they level!
  • Threat Tables: (v1.1) Allow mobs to use Threat Tables, granting increased power and control over their targeting behaviors and causing mobs to behave more like those in RPGs.
  • Mob AI Controls: (v1.1) Allows you to modify mob AI goals, including adding new AI goals found only in MythicMobs. Let zombies open doors, have friendly skeleton guards that fight skeletons from other mob factions, and more!
  • Mob Factions: (v1.1) Allow mobs to be a part of factions! Works with the previously mentioned AI Controls so you can have mobs that will fight other factions of mobs, help players, and more!
  • Plugin Compatibility: Integration with a wide variety of popular plugins!
  • Much more to come!


MythicMobs' commands can be accessed in-game using the /mythicmobs or /mm commands.

After running your server with MythicMobs for the first time, you can find all sorts of example files in the MythicMobs folder to get you started with every aspect of the plugin. Mobs, items and random spawning are all handled through .yml files placed in the respective sub-folders. After editing, you can use /mm reload to reload the plugin, and the /mm mobs command to access your newly-created mobs.

For information on how to configure and use MythicMobs, see the Plugin Manual!

Upcoming Features

Upcoming Features included in the next version will be posted in the Full Changelog.

Future major additions include:

  • Spawner Scaling so that spawners and their mobs can scale their mob level based on the number of players nearby.
  • World Scaling so you can define various conditions for how mobs will scale in level in your world

Help & Questions


  • IRC Chat: #mythicmobs @
  • Official Server:

If you need additional help, please make a post in the Support section of the Plugin Forums. I will sometimes help people who post in the comments, but that is not reliable as I will not always see all the comments being posted. You can also find me in #mythicmobs on, but I am usually AFK and may not be around to respond immediately.

If you'd like a demonstration of what MythicMobs can do, I can occasionally be found on the Minecraft survival server, which is a private server I use for testing my plugins. You can ask mods on there to spawn some of my more complex bosses to demonstrate the plugin's capabilities, but you will probably get obliterated. Mods on will generally not provide support for MythicMobs in general.

Development Builds

Development builds for MythicMobs can be found at my continuous integration server, here:

Please note that development builds have untested features, and while I do not believe they will damage your server in any way, I can make no guarantees about it. They could potentially alter and/or break your previous MythicMobs configurations and may contain bugs and unfinished features. Please make sure you read changelogs fully. Builds that you download which have not been approved by BukkitDev are used at your own risk.


  • mythicmobs.admin - Gives access to all MythicMobs commands.


More info coming soon!


Metrics & Updates

MythicMobs periodically checks BukkitDev for updates (as of v0.7.5) and will try to notify Ops and the console if a new update is available. This can be disabled in the configuration by setting general.check-for-updates to false.

MythicMobs also sends some simple statistics about usage to Metrics can be disabled in the configuration by setting allow-metrics to false.

    Hey, I have a little question to how MythicMobs handles the created mobs. Do plugins that, for example have a zombie give experience for a class when it is killed still work with a MythicMobs Zombie? I guess my question is if MythicMobs creates a new mob, or just alters the basic zombie, that still counts as a Zombie?

    @Moneybags118: Go

    Add the attribute SpawnMethod: replace if you want vanilla mobs to be completely replaced by your random spawns

    Hello again. So I am now experimenting with the plugin on a test server and I really feel this will suit my needs. However I have run into an issue I can't seem to get around. Every time a mythic mob spawns, it spawns a MC mob in the exact same block. So I am getting the mythic mob I am wanting however they always have a MC mob that spawns with them

    My most basic setup is the following:

    -Boss: Priority 1 Chance 0.01 Spawns everywhere outside

    -Zombie Mob Priority 2 Chance 0.9 Spawns from 200Y-256Y

    -Cow Priority 3 Chance 0.1 Spawns everywhere outside

    Thanks in advanced :) -Moneybags

    Would you find a way to make Bosses to spawn in a chunk even if there are no players nearby ? I tried looking for a way to keep chunks loaded, but found nothing good enough.. =S

    Pretty sure Th3helper figured this out somehow.. There were signs counting down the time left for a boss to spawn and it spawned even if there werent players near by .. Please help me if there is a fix!

    - potion 0:SLOW:20:7 >0 1 - potion 0:HARM:10:3 >0 1

    Potion skills cause internal errors in version 2.0.0, will not reload. Is the format updated? its so new that Im sure its not documented yet. PotionSelf skills still work without internal errors.


    nevermind, found the updated format in the examples at the bottom of the skills page, it was so different from the old format I didnt recognize it

    - potion{type=POISON,lvl=2,duration=100} @PlayersInRadius{r=15}

    Im thinking it was because I was using the latest release. I just got the latest dev v2.0.0 and now im seeing the new examples, and they make more sense now. I shall continue my testing. This has really come a long way since EB gold edition!

What feature do you want to see in v1.2?
