Apply Enchantments and Make Items Unbreakable
Accessing Enchantment Options
Open the item editor for the item you wish to enchant. Navigate to the Enchantments section. You'll see a list of available enchantments organized by category or alphabetically.
Adding Enchantments
Click Add Enchantment and select from the available options. Set the enchantment level using the provided input field. Most enchantments have maximum levels (like Sharpness V), but the editor may allow you to exceed vanilla limits if desired.
Making Items Unbreakable
Find the Unbreakable toggle or checkbox in the editor. Enable it to make your item immune to durability loss. This works on tools, weapons, and armor.
Applying Changes
Confirm your modifications. The enchantments and unbreakable tag will be applied to the item's NBT data. When you pick up the edited item, it will display all applied enchantments in its tooltip with the correct glint effect, and durability will no longer decrease during use.
