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.

Unbreaking Enchantment Tool Negative Binomial Graph
The probability of a tool breaking after a number of uses with different levels of this enchantment. Some lower durability materials may last longer than higher durability materials with some enchantment levels.

Obtaining

Unbreaking can be obtained from enchantment tables, drops from mobs that have spawned in a raid,‌ books obtained by fishing, monster room chests, librarian villagers, and non-village structure loot.

Usage

For tools and weapons, there is a 100%÷(level+1) chance that using the item reduces durability, which means that the item has a 50%/66.66……%/75% chance of not using any durability. On average, tools last 2/3/4 times as long.

For armors, there is a 60%+40%÷(level+1) chance a use reduces durability, meaning each durability hit against Unbreaking armor has a 20%/26.66……%/30% chance of being ignored. On average, armor lasts 1.25/1.3636……/1.428571428571…… times as long. Technically, only level below 0 of Unbreaking can lower the reduce-durability chance less than 60%.

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