            <title>[MC-5323] Unbreaking on Armor does not work as well as it should</title>
                <link>https://bugs.mojang.com/browse/MC-5323</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I expected unbreaking three to multiply the length the armor lasted by 4.&lt;/p&gt;

&lt;p&gt;What actually happened was the lifetime of the item was extended, but not by a significant margin. (less than 50%)&lt;/p&gt;

&lt;p&gt;I tested this by having a piece of armor with unbreaking 3 and a piece without unbreaking 3, and fighting mobs. The unbreaking 3 armor(chest) also had protection 4, while the other piece had protection 3(legs).&lt;/p&gt;

&lt;p&gt;The Chest experienced 46 durability damage.&lt;br/&gt;
The Legs experienced 63 durability damage.&lt;/p&gt;

&lt;p&gt;Further Testing(20 hits taken):&lt;/p&gt;

&lt;p&gt;Chest Starting Dur.:236 Final Dur.: 223 Dur. Lost: 13&lt;br/&gt;
Legs Starting Dur.:186 Final Dur.: 166 Lost: 20&lt;/p&gt;

&lt;p&gt;Continued Testing(200 hits taken):&lt;/p&gt;


&lt;p&gt;No Unbreaking: 200 damage(feet) and 200 damage(legs)&lt;br/&gt;
Unbreaking 3: 124 damage(helm) and 137 damage(chest)&lt;/p&gt;


&lt;p&gt;Continued Testing(227 hits taken)&lt;/p&gt;

&lt;p&gt;No Unbreaking: 227 damage(feet, legs, helmet)&lt;br/&gt;
Unbreaking 2: 166 damage(helmet)&lt;/p&gt;</description>

A tool such as swords or pickaxes are (100/(Level+1))%&lt;/p&gt;</comment>

I just assumed that the enchantment was meant to operate exactly the same in all cases. Anyway, thanks for helping to resolve it.&lt;/p&gt;</comment>

                            <comment id="30594" author="demiserofd" created="Tue, 25 Dec 2012 00:22:04 +0100"  >&lt;p&gt;I just tested it, letting two skeletons fire at me 200 times, with two pieces of armor enchanted with unbreaking 3, and two without. The two unenchanted items(boots and legs) took the correct 200 durability damage each, while the enchanted items took 124 damage(helm) and 137 damage(chest). &lt;/p&gt;

&lt;p&gt;Note: This testing took place in both a SMP server and my creative world(while in survival mode, obviously). It&apos;s the same everywhere.&lt;/p&gt;</comment>
                            <comment id="30582" author="demiserofd" created="Mon, 24 Dec 2012 23:47:02 +0100"  >&lt;p&gt;Unbreaking creates a chance of the tool not losing durability when used/hit. Each level of unbreaking decreases the chances of it being used by half; unbreaking 1 doubles its lifespan, unbreaking 2 triples it, and unbreaking 3 quadruples it. &lt;/p&gt;

&lt;p&gt;That information does seem to be outdated. Here is a screenshot showing how I determine my item&apos;s remaining durability:&lt;br/&gt;

&lt;blockquote&gt;
&lt;p&gt;Any &quot;hit&quot; dealt by a mob (including creeper explosions) will remove 2 durability points to the armor.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;Seems to be outdated / incorrect.&lt;/p&gt;</comment>

                            <comment id="30564" author="demiserofd" created="Mon, 24 Dec 2012 21:56:34 +0100"  >&lt;p&gt;I just tested it, by sitting and letting a skeleton shoot at me 20 times. I have the minecraft durability counter enabled, which is what I use to test this whole deal. Here are the stats:&lt;/p&gt;

&lt;p&gt;Chest Starting Dur.:236 Final Dur.: 223 Dur. Lost: 13&lt;/p&gt;

&lt;p&gt;Legs Starting Dur.:186 Final Dur.: 166 Lost: 20&lt;/p&gt;

&lt;p&gt;I counted each shot, totaling 20, so I don&apos;t know where your idea that each shot reduces the durability by two comes from.&lt;/p&gt;</comment>

I assume I was hit by 63 separate attacks, since the legs had no unbreaking enchantment to reduce that number, but as you said, it&apos;s difficult to say precisely.&lt;/p&gt;</comment>

All i need is how many mobs did you approximately get hit by? (yeh hard question &lt;del&gt;.&lt;/del&gt;)&lt;/p&gt;</comment>
