Per-Level Books

Learn how to change book item on each enchantment and each level

Starting 9.17.0, it is possible to change items on each level of a specific enchantment. Similar to how groups can change this. It's very simple to do:

Here is an example with hasten enchantment, where you can for example just change the custom-model-data or you can even change the whole item:

enchantments.yml

hasten:
  display: '%group-color%Hasten'
  applies-to: Tools
  type: MINING
  group: SIMPLE
  applies:
    - ALL_PICKAXE
    - ALL_SPADE
    - ALL_AXE
  levels:
    '1':
    # WE CAN SEE HERE THAT ONLY CUSTOM MODEL DATA IS CHANGED
      item:
        custom-model-data: 99
      chance: 15
      cooldown: 3
      effects:
        - POTION:FAST_DIGGING:0:40
    '2':
    # HERE, MORE PARAMETERS OF THE ITEM ARE BEING CHANGED
      item:
        type: ENCHANTED_BOOK
        name: '&6Harvest II'
        lore: |-
          &7Harvest in a 3x3 area.
          &7Chance to harvest in a 3x3 area.
      chance: 25
      cooldown: 3
      effects:
        - POTION:FAST_DIGGING:1:60
