Armor

Armor adds extra protection via a separate health bar that reaches 10 armor points.

Player armor
Since Indev, helmets, chestplates, leggings, and boots can be crafted by players out of leather, gold, iron, or diamond (in order of increasing durability). This armor prevents part of the damage dealt to the player, including falling, drowning and fire based damage.

All incoming damage is reduced to a certain percentage based upon the effective armor points of the player (effective armor points are described in detail in Item Durability). Each point of armor reduces the damage you take by 8%, up to the maximum of 80%.

Every time the player takes damage the armor loses durability, and its protective capabilities quickly diminish as it loses durability. See Item Durability for more explanation of how armor's durability affects its protective abilities. Materials such as diamond makes a strong armor that withstands quite a bit of punishment, while leather armor barely survives 20 hits. While durability is different, they all have the same efficiency. For example if you wear a leather helmet it will give you the same amount of protection as a diamond helmet.

Chainmail armor can also be hacked into the game, or crafted with edited-in fire blocks. It has the same durability as gold armor.

Before version 1.0.8, wool was used instead of leather as the lowest tier of armor in Alpha.

Armor crafting
It takes 24 units of material to make a full set of armor. Although it is not necessary that all of your armor is the same material, each individual piece must consist of only one material.

Note that it is most efficient to craft boots before a helmet because, while they both provide 1.5 armor points, boots require less material.

Mob armor
In Survival Test, certain Zombies could be found wearing armor; a chestplate and/or a helmet. Zombies had the potential, although extremely unlikely, to wear both a chestplate and a helmet at the same time. Skeletons could also be found wearing armor, albeit extremely infrequently. Mob armor was purely cosmetic, however, although it is possible that it was a planned feature to increase mob difficulty.

Trivia

 * The armor pieces for leather have names different than that of the armor pieces created by ore. The pieces are named caps, tunics, and pants.
 * If you look in the armor folder inside Minecraft.jar, leather armor is still called cloth armor. See Cows for more info.
