For Minecraft: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 Minecraft:fishing rods or getting blown up with Minecraft:TNT, Unbreaking is applied for each point of decision of actual reduction.
