Creating Custom Items

Starting from Minecraft 1.21, it is possible to apply the abilities of artifacts on other items using item components. The item must be equipped in an armor slot or in a curio/trinket/accessory slot in order for the abilities to apply. Items can be made equipable in a slot by giving the item the corresponding item tag, more information can be found on the Curios/Trinkets/Accessories wikis. The item components available in the latest version of Artifacts are listed below (all components use the artifacts: namespace).

Component fields accepting a boolean, integer, double or tool tier will generally accept the name of an item config value of the same type. For example, the following command summons Iron Boots that replenish the player's hunger using the rooted_boots.hungerReplenishingDuration value set in the item config.

/give @a iron_boots[artifacts:replenish_hunger_on_grass={duration:"rooted_boots.hungerReplenishingDuration"}]

Some components have an optional enabled field, which, when set to false, disables the component entirely. These are used in combination with an item's enabled config option, to remove the need to restart the game after changing the config.
