MythicMobs

The foundation of the Mythic suite: a YAML system for custom mobs, a scripting language of mechanics, targeters, triggers and conditions, plus items, drop tables, spawners and stats. This page covers the file layout, the anatomy of a skill line, and the complete indexes of every documented mechanic, targeter, trigger and condition.

📌 Scope note

MythicMobs is a Paper/Spigot server plugin, not a data pack — its content lives in plugins/MythicMobs/ as YAML. Version syntax on this page targets the 5.13.x line. Where the docs mark a feature as Premium-only it is flagged; see free vs premium.

File layout & commands

Content is split by kind, each in its own folder. Any number of .yml files may live in each — Mythic merges them, so one file per mob or one file for fifty both work.

plugins/MythicMobs/

config/           # config-general, -mobs, -items, -skills, -spawning
Mobs/             # mob definitions
Skills/           # metaskills
Items/            # item definitions
DropTables/       # drop tables
Spawners/         # spawner definitions (see the warning below)
RandomSpawns/     # natural-spawn rules
Stats/            # custom stat definitions
packs/            # self-contained content bundles

The base command is /mm (alias /mythicmobs). Required arguments are shown in [], optional in <>.

Command	Does
`/mm reload` (`/mm r`)	Reloads the plugin.
`/mm debug [level]`	Sets debug level; `0` is off.
`/mm debugmode [true\|false]`	Disables random/mob spawners and other noise that makes debugging hard.
`/mm mobs spawn [mob]:<level> <amount> <world,x,y,z,yaw,pitch>`	Spawns a mob.
`/mm mobs info [mob]`	Dumps everything Mythic knows about a mob definition.
`/mm mobs list` / `listactive`	Loaded definitions / currently spawned mobs.
`/mm mobs kill [mob]` / `killall`	Removes mobs by name, or all of them.
`/mm items get [item] <amount>`	Gives yourself a Mythic item.
`/mm item import <itemName> [fileName]`	Imports the held item into `Items/`.
`/mm egg get [mob] <amount>`	Gives a spawn egg for a Mythic mob.
`/mm test cast [metaskill]`	Casts a metaskill for testing.
`/mm camera <pathId> add\|remove [index]` 5.13.0	Authors cinematic camera paths in-game.
`/mm save`	Force-saves active mobs and spawners.

Several commands take flags before their first argument:

Flag	Effect	Example
`-s`	Silent — no chat feedback.	`/mm test cast -s [metaskill]`
`-p <player>`	Execute at the given player.	`/mm m s -p <player> [mob]`
`-t`	Execute at your target location.	`/mm m s -t [mob]`
`-n`	Fake a `NATURAL` spawn reason instead of `COMMAND`.	`/mm m s -n [mob]`
`-f [faction]`	Act on all mobs of a faction.	`/mm m kill -f [faction]`
`-d`	Drop on the ground if the inventory is full.	`/mm i give -d [item]`

Defining a mob

Only two things are required: the internal name (the YAML key, no spaces, unique) and Type. Everything else is optional.

plugins/MythicMobs/Mobs/example.yml

SkeletalKnight:
  Type: WITHER_SKELETON
  Display: '<gold>Skeletal Knight'
  Health: 200
  Damage: 12
  Armor: 15
  Faction: undead
  Options:
    MovementSpeed: 0.25
    PreventOtherDrops: true
    Despawn: false
  Equipment:
  - IronSword HAND
  - DiamondHelmet HEAD
  Skills:
  - skill{s=KnightSlam} @target ~onAttack 0.2
  Drops:
  - GoldCoin 1-4 0.5
  - exp 50 1

The documented top-level mob options are:

Option	Purpose
`Type`	Base entity type. Required. New vanilla entity types only work once Mythic adds support.
`Display`	Display name; supports colour codes and placeholders. Does not auto-update — use the `setname` mechanic to change it later.
`Health`	Base max health. Spigot caps this at `2048` by default (raise it in `spigot.yml`).
`Damage`	Base melee damage. 1 damage = half a heart. Never affects ranged/projectile damage.
`Armor`	Base armor attribute. Minecraft caps armor at 30.
`HealthBar`	Hologram health bar above the mob (`Enabled`, `Offset`).
`BossBar`	Wither/dragon-style bar (`Enabled`, `Title`, `Range`, `Color`, `Style`, `CreateFog`, `DarkenSky`, `PlayMusic`).
`Faction`	Faction name, used by custom AI and targeter filtering.
`Mount`	Another Mythic mob to spawn and ride.
`Options`	Large per-entity option block (movement speed, despawn, collidability, …).
`Display Options`	Options specific to display entities.
`Modules`	Opt-in behaviour modules such as threat and immunity tables.
`AIGoalSelectors` / `AITargetSelectors`	Replace the vanilla AI goal/target lists outright.
`AIPathfindingMalus`	Per-block pathfinding cost overrides.
`Drops`	Inline drop list (see Drops).
`DamageModifiers`	Per-damage-type multipliers — immunity, healing from a type, resistances.
`Equipment`	Items placed in equipment slots on spawn.
`KillMessages`	Custom death messages.
`Level` / `LevelModifiers`	Base level and per-level stat scaling.
`Disguise`	LibsDisguises integration.
`Skills`	The skill list (see below).
`Nameplate`	Nameplate rendering options.
`Hearing`	Lets the mob react to sounds.
`Totem`	Totem behaviour.
`Variables`	Per-mob variables set at spawn.
`Trades`	Villager trade definitions.

⚠ Gotcha

Display is rendered once. A name containing a placeholder such as <caster.hp> will show the value from spawn time and then sit there stale. To keep it live you must re-apply it, e.g. setname on a repeating timer skill.

Anatomy of a skill line

Every skill line follows one grammar. Only the mechanic is mandatory:

The general form

- mechanic{argument=value} @[targeter] ~on[trigger] [health_modifier] [chance]

A concrete line, and what each part contributes:

plugins/MythicMobs/Mobs/fiery.yml

FieryZombie:
  Type: ZOMBIE
  Display: 'Fiery Zombie'
  Health: 50
  Skills:
  - ignite{ticks=100} @target ~onAttack <50% 0.5

Part	In the example	Meaning
Mechanic	`ignite`	What happens. The base action. Required.
Arguments	`{ticks=100}`	In braces, separated by `;`. Most have defaults.
Targeter	`@target`	What it is aimed at. Always prefixed `@`; may take its own `{}` options.
Trigger	`~onAttack`	When it fires. Prefixed `~`. Only valid in a mob's own `Skills` list.
Health modifier	`<50%`	Only run while the caster's health is under (or over, with `>`) that fraction.
Chance	`0.5`	Probability from 0 to 1 that the line executes.

There are 20 ticks in a second, so ticks=100 is five seconds. Long argument lists may be wrapped for readability as long as the YAML indentation stays valid:

Wrapped argument style

Skills:
- mechanic{option=value;
           option=value;
           option=value}

Metaskills

A metaskill is a named, reusable skill defined in Skills/ and invoked with the skill mechanic. This is where conditions, timers and multi-step sequences live.

plugins/MythicMobs/Skills/knight.yml

KnightSlam:
  Cooldown: 8
  Conditions:
  - targetwithin 5
  Skills:
  - sound{s=entity.generic.explode;v=1;p=0.8} @self
  - particles{p=explode;amount=30;hS=1;vS=0.5} @origin
  - damage{amount=18} @EntitiesInRadius{r=4}
  - throw{velocity=6;velocityY=3} @EntitiesInRadius{r=4}

Calling it accepts several equivalent spellings:

Skills:
- skill{skill=KnightSlam}
- skill{s=KnightSlam}
- skill:KnightSlam

📌 Premium

Skill parameters — passing arguments into a metaskill so one definition serves many callers — are a Premium feature, as are in-line target conditions and origin=@targeter.

💡 Best practice

Match the targeter's kind to the mechanic's. A location mechanic given an entity targeter (or the reverse) is the single most common reason a skill silently does nothing. /mm mobs info and a raised /mm debug level will show what a skill actually resolved to.

Trigger index

Triggers are only valid inside a mob's own Skills list — a metaskill's internal lines inherit the trigger of the line that called them. Use @trigger to target whatever caused the trigger to fire. 36 documented:

Trigger	Fires when
`onCombat`	Default
`onAttack`	When the mob hits something
`onDamaged`	When the mob is damaged

`onTimer`	Every \# ticks (where \# is the interval in ticks)
`onInteract`	When the mob is right-clicked

`onEnterCombat`	When the mob enters combat (requires threat tables be on)
`onDropCombat`	When the mob leaves combat (requires threat tables be on)
`onChangeTarget`	When the mob changes targets (requires threat tables be on)
`onExplode`	When the mob explodes (typically only used for creepers)
`onPrime`	When the creeper charges up for an explosion

`onEnterBounds`	When the mob moves into a defined region
`onExitBounds`	When the mob moves out of a defined region

Condition index

Conditions gate execution. The Type column says what a condition inspects — Entity, Location, Meta or Compare — which determines where it is legal to use. 194 documented:

Conditions appear in four places, each with its own semantics:

Block	Checked against
`Conditions`	The caster.
`TargetConditions`	Each target — non-matching targets are filtered out.
`TriggerConditions`	The entity that triggered the skill.
`EquipConditions`	(Crucible items) the wearer, before stats and skills apply.

Each condition line may carry an action that changes what a match does, rather than just pass/fail:

Action	Effect on a match
`true`	The skill runs if the condition is met. (Default.)
`false`	The skill runs only if the condition is not met.
`cast <skill>`	Casts a metaskill when matched.
`castinstead <skill>`	Casts a metaskill in place of the original.
`power <multiplier>`	Multiplies the skill's power (e.g. `2.0` doubles it).
`orElseCast <skill>`	Casts a fallback skill when not matched.

Drops & drop tables

The simplest form is an inline list of <drop> <amount> <chance>:

plugins/MythicMobs/Mobs/example.yml

internal_mobname:
  Type: ZOMBIE
  Drops:
  - GoldCoin 1-3 0.5
  - diamond 1 0.05
  - exp 50 1

Drop — a Mythic item, a vanilla item, exp, a drop table, or an item from a supported plugin.
Amount — a number or a range (1-3 / 1to3). Note the upper bound is exclusive: 1to3 yields 1 or 2, never 3.
Chance — 0 to 1, or a percentage such as 10%.

📌 Premium — dynamic chances

A chance may be a math expression, placeholder or variable that resolves to a number, evaluated per loot roll — so drop rates can scale with mob level or a variable. Resolving to ≥1 always drops, ≤0 never does. Requires Premium (math/variables in numeric values). Works with FancyDrops.

Spawners

Spawners are fixed points with timers, cooldowns, warmups and conditions. They work independently of vanilla natural spawning.

plugins/MythicMobs/Spawners/example.yml

SpawnerName:
  MobName: mobTypeName
  World: worldname
  SpawnerGroup: GroupName
  X: 0
  Y: 0
  Z: 0
  Radius: 0
  RadiusY: 0
  UseTimer: true
  MaxMobs: 1
  MobLevel: 1
  MobsPerSpawn: 1
  Cooldown: 0
  Warmup: 0

🚧 Workaround

Once a spawner file has been loaded by a running server, editing it in a text editor will not stick — the server rewrites it from memory. Either edit spawners with in-game commands, or stop the server first. Spawner commands accept g:group_name to act on a whole group and r:radius to act on everything within a radius.

⚠ Version differences

5.13.0 Spawners gained Chance, RandomRotation and UseWorldScaling.
5.13.0 Most spawner fields — Cooldown, Warmup, MobsPerSpawn, MobLevel, Radius, RadiusY, ActivationRange, ScalingRange, LeashRange — now accept placeholders and ranged values, where previously they took flat numbers only.

5.13.0+ ranged and random spawner options

Chance: 0.5
RandomRotation: true
Cooldown: 5to10
MobsPerSpawn: 1to3

Math, variables & placeholders

Placeholders resolve values at runtime — <caster.hp>, <target.name>, <skill.var.damage> and so on. Variables are named values scoped to a caster, skill, world or the server, set with the setvariable mechanic.

📌 Premium

Using placeholders and math inside numeric fields — mob attributes, item attributes, most skill arguments and drop-table amounts — is a Premium capability. On the free build those fields accept literal numbers only. This is the single biggest practical difference between the two tiers, because most advanced configs found online assume it.

Version history

MythicMobs keeps per-minor changelog files from pre-2.0 through 5.9.x, with 5.10 onward in a single master changelog. Highlights of the current line:

Version	Notable changes
5.13.0	Cinematics system — keyframed camera paths under `cutscenes/`, played with `cinematicCamera` (aliases `cinecam`, `camerapath`), with looping, per-leg easing, a packet-only `DISPLAY` camera or `TELEPORT` fallback, and `onStart`/`onEnd` skills. Adds `cinematicCancel`, the `isInCinematic` condition, `cinematic.*` placeholders, `/mm camera`, and cancellable start/end API events. New `clearpath` mechanic (clears navigation). `mount`/`summonPassenger` gain `mode` = `ADD`/`SET`/`REPLACE`. `packinfo.yml` gains `PackDependencies`/`FileDependencies`. Spawner `Chance`/`RandomRotation`/`UseWorldScaling` plus placeholders in spawner fields. Placeholders accepted in numeric attributes across 40+ mechanics. Menu icons gain `Hide`, `HideFlags`, `Glint`, `Enchantments`. `CRITICAL_STRIKE_DAMAGE` reverted to a compounding multiplier; a lost-update race in stat recompute fixed.
5.12.1	Maintenance release on the 5.12 line.
5.12.0	Large feature release (the master changelog's second-biggest section).
5.11.0	Feature release.
5.10.0	First entry in the current master changelog.
≤ 5.9.x	Documented in per-minor files under `changelogs/`. The 5.9 line was heavily 1.21.5-compatibility focused (projectile, equipment, display-packet and drop-weight fixes).

📌 Note

The upstream changelog summarises 5.10–5.12 far less granularly than 5.13. Rather than reconstruct those release notes second-hand, this page reports only what the changelog states; consult the changelog directly for the full 5.12.0 entry.

Gotchas

Entity-type support lags Minecraft. Mob options for newly added vanilla entity types do not function until Mythic explicitly adds support, and some types have quirks documented on the wiki's unstable-entity-types page.
Triggers do not work inside metaskills. A ~onX on a line inside a metaskill is meaningless; put the trigger on the mob's skill line that calls the metaskill.
Health caps. Spigot caps max health at 2048 regardless of what you write in Health; Minecraft caps armor at 30.
Range upper bounds are exclusive in drop amounts — 1to3 never yields 3.
Addon mechanic collisions. If two addons register the same name, disambiguate with a namespace prefix such as meg: — see interoperation.
Equipment and attribute modifiers stack into base stats. Items with attribute modifiers change the mob's effective health, damage and armor beyond what the mob file declares.
