Mending is one of the most powerful enchantments in Minecraft that essentially allows players to restore the durability of certain items and make them stronger with the help of EXP (Experience) orbs.

What does mending actually do?

The Mending enchantment uses xp (experience) to mend your equipped tools, weapons and armor. Each time you gain experience by killing mobs or mining certain items, the experience earned will automatically be used to repair any damaged tools, weapons or armor that you have equipped (and are enchanted with Mending).

Does mending items break?

Simply put, a Fishing Rod equipped with Mending will never break and rarely (if ever) need to be repaired or maintained. One important note: Mending is mutually exclusive with Infinity. You can either have infinite arrows or a Bow that can be repaired; you won't be able to use both without using cheats.
