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 \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 level+1 times as long.

For armor, there is a \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 \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.
