Plugin integrations/conflicts

Can I use MythicMobs with MobArena?
Yes, with the MobArenaExtension plugin by Sait. Information about how to install and set up the extension is listed on the Github project page.

Please note that MobArenaExtension is not officially supported. Any and all questions about it should go to Sait.

Can I use Citizens NPCs in MobArena?
Yes, as long as the NPCs are outside of the arena and lobby regions.

MobArena removes foreign/unknown entities from its regions, so Citizens NPCs will also get removed. You can get around this by placing the NPC just outside of the region. To prevent players from leaving the lobby or arena through the hole that is created, it may be necessary to wall off the NPC and protect the "extra" region using another plugin, e.g. WorldGuard.

My players can't kill wolves! Whats going on?
WorldGuard is preventing damage to animals.

Check for a WorldGuard region that overlaps your arena region and set its damage-animals flag to allow.

Regions

How can I change the arena structure after setting up the region?
You can change the region by entering Edit Mode (type /ma edit <arena>).

MobArena protects its regions unconditionally - it doesn't care that you are op. To temporarily disable the protection, you can enter Edit Mode for the given arena. Remember to disable Edit Mode (same command) once you are done editing the structure.

I get kicked from the arena with the message "Leaving so soon?"
You were kicked for leaving the arena region. This is the only reason MobArena will ever send that message.

Go back into Setup Mode and make sure the region is covering the entire arena. The region must be a 3D box, not just a 2D rectangle (see Arena Setup).

Can I make a circular or cylindrical arena region?
No, this is not currently possible.

Note that arena regions are allowed to be larger than the physical arena structure they contain, so if it isn't a problem for you that the arena region is bigger than the arena structure, it isn't a problem for MobArena either.

Classes

How do I enchant items in the config?
This is explained on the Item and Reward Syntax page with syntax and examples.

Why do my potions turn into water bottles?
This is a known bug on Minecraft 1.8 servers.

You can get around it by setting unbreakable-weapons: false in your classes (see Setting up the config-file).

Can I block a certain type of item from the My Items class?
No, this is not currently supported.

Note that items like Ender Chests and Shulker Boxes (as well as some of the materials to make them) are removed while the players are in the arena to prevent item smuggling.

Can I disable the inventory restore functionality for the My Items class?
No, this is not currently supported. There is an open issue about it.

Mobs

Why do bosses die in few hits with health set to high or psycho?
This is because Spigot limits the "max max health" of mobs to 2048 by default (see SPIGOT-299), so when MobArena tries to set the health higher than that, Spigot throws an error.

You can fix this by increasing the "max max health" property. Open spigot.yml, located in the server root folder, and change the maxHealth value from 2048.0 to something larger, e.g. 10000000.0 (ten million):

settings:
  # ...
  attribute:
    maxHealth:
      max: 10000000.0
