Anvil Recipes

Anvil recipes allow custom anvil crafting behavior with experience cost and component copying support.

YAML Example

type: 'anvil'
result: 'minecraft:diamond_sword'
base: 'minecraft:iron_sword'
addition: 'minecraft:diamond'
cost_level: 3
copy_components_rules:
  - 'enchantments'
  - 'display_name'
  - 'lore'

Fields

Field	Type	Required	Description
type	string	Yes	Must be anvil
result	string	Yes	Output item ID
base	string	Yes	Left anvil slot item (base item)
addition	string	Yes	Right anvil slot item (addition ingredient)
cost_level	integer	No	Experience levels consumed, default 0
copy_components_rules	list	No	Component copy rules (see Smithing Recipes)
fake_result_preview	string	No	Fake preview item shown during crafting

Difference from Vanilla Anvil

• Vanilla anvil: item repair, enchantment combining, renaming
• Custom anvil recipes: fully custom input → output mapping, bypassing vanilla logic

Enable / Disable

Anvil recipe functionality can be globally controlled in config.yml:

enable_anvil_recipe: true

Set to false to disable all custom anvil recipes.

Copy Components Rules

Note: It is recommended to use the new result_processors configuration option, which provides more powerful features. The old copy_components_rules syntax is still compatible. See Result Processors.

Same as smithing recipes. See Smithing Recipes — Copy Components Rules for the full list of supported rules.

Notes

• Both base and addition support item packs (item_pack:) and item tags (tag:)
• Anvil recipes support ingredient amounts, e.g. tag:minecraft:planks 4 requires 4 of every item in the tag. Item packs also support this, e.g. item_pack:all_wood 4
• The amount suffix is only valid in anvil recipes; ingredients of other recipe types do not support amounts
• cost_level of 0 means no experience is consumed
• When multiple anvil recipes match the same input, the first matching recipe is used
