| Description |
|
I expected unbreaking three to multiply the length the armor lasted by 4. What actually happened was the lifetime of the item was extended, but not by a significant margin. (less than 50%) 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). The Chest experienced 46 durability damage. Further Testing(20 hits taken): Chest Starting Dur.:236 Final Dur.: 223 Dur. Lost: 13 Continued Testing(200 hits taken): No Unbreaking: 200 damage(feet) and 200 damage(legs) Continued Testing(227 hits taken) No Unbreaking: 227 damage(feet, legs, helmet) |

According to the wiki, the equation for the percent chance of degrading is this: (60 + 40/(Level+1)) |

Apologies if this wasn't actually a bug. I just assumed that the enchantment was meant to operate exactly the same in all cases. Anyway, thanks for helping to resolve it. |

In some cases, where I would want my armor to last longer, I'd prefer a functional Unbreaking enchantment for armor over any Protection-type enchantment.... |

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). Note: This testing took place in both a SMP server and my creative world(while in survival mode, obviously). It's the same everywhere. |

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. That information does seem to be outdated. Here is a screenshot showing how I determine my item's remaining durability: |

Wiki: http://www.minecraftwiki.net/wiki/Armor
Seems to be outdated / incorrect. |

Does unbreaking decrease the chance of losing a durability point or does it actually change the durability of the armor/tool? |

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: Chest Starting Dur.:236 Final Dur.: 223 Dur. Lost: 13 Legs Starting Dur.:186 Final Dur.: 166 Lost: 20 I counted each shot, totaling 20, so I don't know where your idea that each shot reduces the durability by two comes from. |

Every hit of a mob decreases the durability by 2 , so that should've been 32 attacks. |

Apologies, I'm new at this. 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's difficult to say precisely. |

Unbreaking has only a chance for the armour to be used up.Please make a more in-depht description if you can give more info |
