Graphs showing 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.
For tools and weapons, there is a chance that using the item reduces durability, which means that for levels I, II, and III the item has a , , or chance of not using any durability. On average, tools last 2, 3, or 4 times as long.
For armor, there is a chance a use reduces durability, meaning each durability hit against Unbreaking I, II, and III armor has a , , or chance of being ignored. On average, armor lasts about 1.25, 1.36, or 1.43 times as long. Levels below 0 can lower the chance to reduce durability to 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.
