• Renaming and repairing items is free.
• Enchanting an item with a normal enchantment costs 3 levels for each enchantment level added. Some examples of costs with this system:
  • Unenchanted sword + Sharpness 2 book would cost 6 levels (Sharpness 0 -> 2).
  • Efficiency 2 pickaxe + Efficiency 2 book would cost 3 levels (Efficiency 2 -> 3).
• Enchanting an item with a treasure enchantment costs 15 levels.
• The invisible repair_cost data on items that made repairing/enchanting them more expensive in the future is no longer used.

• If the enchantment applies to multiple types of gear, it cycles through the icons one at a time.

• If the enchantment applies to most gear/items like Unbreaking and Curse of Vanishing, it uses a book icon instead.

Enchanted books now stack to 16.

(In the future, there may be some rare item/mechanic allowing you to unlock a level 4 enchantments. No promises, though.)
