Instance Multi-File Rules

config/mite contains both primary configuration files and the external rule directories for the current game instance. On first launch, MITE copies 71 default rule JSON files into their corresponding subdirectories. Each file can then be added, changed, or removed independently.

config/mite/
|- mite-common.json
|- mite-client.json
|- arrows/
|- bucket_families/
|- butchering/
|- crops/
|- earth_elementals/
|- entity_drops/
|- fishing/
|- livestock/
|- mob_replacements/
|- portals/
|- repair/
|- rune_gates/
|- saplings/
|- silverfish/
|- skeleton_projectiles/
`- village_conversions/

Default-file lifecycle

• .defaults-installed records default relative paths provided by the current or earlier versions.
• New defaults introduced by an update are copied in.
• Old default files that the user deliberately deleted do not return on every launch.
• Updating MITE never overwrites an existing customized file.

Back up the complete directory before upgrading. To restore a default, remove its file and recorded marker path before restarting, or extract it from mite/defaults in the mod JAR.

Matching and precedence

Selectors accept item, block, or entity IDs and #tag values as either one value or an array. Higher integer priority matches first; equal priorities are ordered by relative file path.

The loader only scans the 16 rule subdirectories listed below. It never treats mite-common.json or mite-client.json in the root as rule files.

This is not a data-pack directory

These files belong to server-instance configuration and do not go in a world's datapacks folder. Modpacks should distribute them under the corresponding config/mite subdirectories.

Directories and fields

Directory	Required fields	Common optional fields/enums
entity_drops	entities, mode, items	mode: wight_rare_pool, arachnid_webs
mob_replacements	entities, replacement, profile	giant_vampire_bat, longdead_guardian, infernal_creeper
arrows	items, recovery	silver_damage, acid_resistant; recovery profiles from flint through adamantium
skeleton_projectiles	entities, projectile	damage_profile: default, longdead, longdead_guardian
crops	blocks, young_output, mature_output	immature_output, blighted_output, mature_base_count, mature_bonus
saplings	blocks	requires_precipitation, biome_tag, temperature: none/oak/birch
livestock	entities, food, grazing, meat, raw_meat, cooked_meat, manure	produces_milk, egg_output, feather_output, manure_output, bowl_milk_output
butchering	entities, raw_output, cooked_output	mode: random_extra/single_special, requires_wellness
repair	items, material, tier	costs can override armor slots and tool types
bucket_families	material, empty, water, lava, milk, stone	Materials: copper, silver, gold, iron, ancient metal, mithril, adamantium
fishing	mode, success	target_block, fallback; modes deep_ocean/grass_worm
earth_elementals	spawn_blocks, type, tool_block, drop_block	Tags can extend valid spawning bases
portals	source_dimension, target_dimension, color	foundation, rune_gate
rune_gates	corner_blocks, radius	radius: mithril/adamantium
village_conversions	blocks, replacement	Living-to-dead crop mappings
silverfish	condition, result	Conditions source_block/dimension/nearby_block with matching source, dimension, or nearby

Every directory supports priority, defaulting to 0.

Example: add a modpack silver arrow

config/mite/arrows/example_silver_arrow.json

{
  "items": ["example:silver_arrow", "#example:silver_arrows"],
  "recovery": "silver",
  "silver_damage": true,
  "priority": 20
}

The damage multiplier does not belong in this file; use production.silverArrowUndeadDamageMultiplier.

Example: custom repair material

config/mite/repair/example_mithril.json

{
  "items": "#example:mithril_equipment",
  "material": "#c:nuggets/mithril",
  "tier": "mithril",
  "costs": {
    "helmet": 10,
    "chestplate": 16,
    "pickaxe": 6,
    "standard_tool": 4
  },
  "priority": 20
}

Run /reload after editing. Reloading bucket-family rules also refreshes dispenser behavior.
