Infernal Mobs


Mobs will randomly become "infernal", then they will become mini bosses. They get a random amount of random powers, a name tag proclaiming them "infernal", and when they die they will drop random enchanted loot. I saw this mod for Forge made by Atomic Stryker, and thought I would make a version for Bukkit. Most aspects of this mod are configurable.

The download comes with 100+ predefined loot drops, but there are so many options to define and create your own loot, that this plugin may as well be a loot drops plugin!



You can make Infernal Mobs drop magic staffs by installing my plugin WizardlyMagic.

Then copy the contents of this paste-bin to the bottom of your loot file.
If you modified your loot file, or have an old version, you may need to edit the index numbers.

Then reload your loot file with /im reload, then the staffs should drop!

- MobArena v0.96.6
- Any plugin (like MCMMO) that uses score-boards may cause lagg when combined with IM (if you have IM score-boards enabled).

    I'm getting something like

    [21:20:45 WARN]: [InfernalMobs] Ability: ghost is not set!
    [21:22:06 WARN]: [InfernalMobs] Ability: confusing is not set!

    and suddenly the whole server lagging unbearable.

    The timings shows InfernalMobs is consuming too much workload:
    66.07% 2,677.38% 109.77 s 1,338.69 ms 0.1 0.1k Task: infernal_mobs$4(Single)
    1.45% 253.75% 2.41 s 126.87 ms 0.0 0.0k EventListener::onEnitityDamaged(EntityDamageEvent)
    1.24% 588.22% 2.06 s 294.11 ms 0.0 0.0k EventListener::onEntityAttack(EntityDamageByEntityEvent)

    Please check out this issue, thanks a lot.

    Did you paste the stuff it says to in your loot file?

    How do the Staffs work? I have Wizardly Magic installed, but they still don't do anything!

    Updated them, also added a page showing all the loot options.

    Hi, was just wondering when you'll be updating the Enchantments and Potion Effects lists to include the new effects in 1.9? I have some ideas for new loot that I'd like to add to my server.

    Thanks again for all your great work!

    Found out it's something to do with BarAPI, Tested it without pwp, and it still came up when you'd hit a infernal mob.

    I too am getting a lot of InfernalMobs seems like when it's happening it also slows down the server.

    See link below for the error I am getting - this literally spams over and over and over like a thousand times time per second once it starts occurring, but as far as when it happens it seems completely intermittent.

    @XxDawnsusxX: Go

    Try running it without per-world plugins and see if the error persists.

What Infernal Mob Power should I add next?
