Unbreaking

Unbreaking is an enchantment that gives a chance for an item to avoid durability reduction when it is used, effectively increasing the item's durability.

Obtaining[]

Unbreaking I, Unbreaking II, and Unbreaking III can be acquired using an enchanting table, by fishing, finding an enchanted book in dungeon chests, and by trading with a librarian villager.

Usage[]

For most items, there is a ${\displaystyle \frac{100}{level+1} \%}$ chance that using the item reduces durability. Meaning the item has a 50%/~66%/75% chance of not using any durability. On average, tools last ${\displaystyle level+1}$ times as long.

For armor, there is a ${\displaystyle \left( 60 + \frac{40}{level + 1} \right) \%}$ chance a use reduces durability, meaning each durability hit against Unbreaking armor has a ~20%/27%/30% chance of being ignored. On average, armor lasts ${\displaystyle \frac{1}{0.6+\frac{0.4}{level+1}}}$ times as long.

When durability is reduced by multiple points, as when hooking a mob with fishing rods or getting blown up with TNT, Unbreaking is applied for each point of reduction.
