    Profession: NITWIT
    Type: DESERT
    Level: 2
      Item1: 5 EMERALD

Chain Mechanic

A really cool new mechanic! See entry in the mechanics section.


  • Added -p flag to mob spawn command, allowing you to spawn mobs at aspecific player

NEW: BarCreate

NEW: BarSet

NEW: BarRemove

NEW: BlockWave

Creates a wave of blocks. This effect is client-side (there is no risk to your server).

NEW: BloodyScreen

NEW: Chain

This allows you to make skills that bounce between targets, like a “chain lightning” type skill.

BounceConditions are evaluated after each “bounce” of the skill. With the example, if someone were on the other side of a wall from the mob but you were standing in the doorway, it could bounce from you to them since it bounced around the wall

It will only bounce to the same entity per cast once. Also every time the skill bounces, the entity it is bouncing from will be the “origin” in the skill and the inherited target of onBounce will be the next entity it is bouncing to, so fromOrigin is your friend for making effects!


  1. chain{


      - effect:particleline{p=flame;fromOrigin=true}
      - inlineofsight
      - hasaura{aura=damageResist} false
  } @target ~onTimer:20

NEW: CloseInventory

NEW: MountMe

NEW: SendToast

NEW: Stun

  • The Cast mechanic will show a hologram castbar if showCastBar=true


  • Added damageType option, can be set to whatever you want

  1. damage{amount=10;element=FIRE} @target ~onUse
  2. damage{amount=10;element=ICE} @target ~onUse
  Type: COW
  - FIRE 2.0
  - AIR 1.0
  - ICE 0.5
  - message{m="Damaged by <skill.var.damage-type> for <skill.var.damage-amount>"} @PIR{r=50} ~onDamaged


  • Added damageMods option, letting you create auras that apply damage modifiers.
  • Can also specify custom damageMods that you use in the damage mechanic

        - particles{p=flame;amount=10;hS=0.4}
      damageMods="FIRE 0.5"} @self ~onInteract

Better MetaSkills

MetaSkills can now in many places be put in-line instead of having to reference another skill. This means you will no longer have to make multiple small skills in order to use certain complex meta-skills, such as projectiles.

This is done by creating a new list of mechanics surrounded by square brackets []s instead of putting a skill name. You can do this to nest skills pretty much infinitely. Each new list of skills should be properly indented to make sure YAML reads them correctly.

- projectile{
      interval=1; velocity=30; bulletType=BLOCK; material=MAGMA_BLOCK; tyo=0.5; g=1; bulletSpin=-40; hnp=true; stopatentity=false; duration=100;
          - damage{amount=50}
          - ignite{ticks=20}
          - particles{p=flame;a=20;hs=0.5;vs=0.5}
          - particles{p=largeexplode;a=50;speed=1;hs=0.05;vs=0.05}
          - effect:sound{s=entity.dragon_fireball.explode;p=0.6;v=2}
          - damage{amount=30} @ENO{r=5}
  } @targetlocation


This feature is Premium-only.

You can now use math and numeric placeholders in lots of places! The plan is to expand this to be usable anywhere, but it's a big undertaking.

In order to use math where able, you can simply put placeholders and equations between '' where you'd normally put a number value.

For example:

- damage{amount=1}
- damage{amount='5 + 5'}
- damage{amount='<caster.level> * 10'}

and so on

The following mechanics can use math so far:

  • damage
  • damagePercent
  • heal
  • healPercent
  • setLevel

Math is also usable in drop amounts:

- gold_nugget '1 + (0.2 * <caster.level>)'

Projectile Bullets

Projectile mechanics can now specify a bullet type that will represent the projectile. No longer are projectiles just limited to particles!

These work with the projectile, missile, and orbital mechanics.

Bullet types available are:

  • ARROW - projectile{bulletType=ARROW;…}
  • BLOCK - projectile{bulletType=BLOCK;material=STONE;…}
  • ITEM - projectile{bulletType=ITEM;material=STONE;…}
  • MOB - projectile{bulletType=MOB;mob=SkeletonKing;…}

Yes, that's right, you can even shoot projectiles made up of other Mythic mobs! Mobs shot with the projectile skill cannot be interacted with, but will still use all their skills…

You can also use the new bulletSpin=# option to give your bullets some spin.


Added support for all 1.14 mob types.


NEW: onShoot

A special Aura mechanic that adds a temporary onShoot skill to the target.

- onShoot{auraName=fireball_bow;onShoot=[ shootfireball ];duration=200;charges=5} @self

In this example, the caster's next 5 bow shots will shoot fireballs instead of arrows.

NEW: Speak

Speak is similar to the message skill, but is used for making mobs “talk”. Mobs will talk in the chat using a configured syntax, and if you have a hologram plugin installed, they will also have speech bubbles!

  1. speak{m=“OH BOY I HAVE SPEECH BUBBLES NOW”} @trigger ~onInteract
