Protection

Protection is an enchantment applied to armor that increases the armor's damage reduction.

Usage
Protection has no effect on damage from the void, the command, or hunger. $$, protection does not reduce damage from status effects like poison or wither, nor does it reduce damage from suffocation. Otherwise, the damage is protected, even if armor normally would not protect against it (e.g. damage from harming potions). When enchanted armor reduces damage from a source that armor does not normally protect against, it does not lose any durability.

The formula for damage reduction is or  for each armor piece. Note that the actual amount of protection is capped at 80%. $$, a full set of armor with Protection IV is sufficient for this maximum amount of protection.

Damage reduction from Protection, Fire Protection, Feather Falling, Blast Protection, and Projectile Protection stacks up to an upper limit cap (see armor enchantments).

The protection enchantment is applied after the armor's protection. For example, 20 armor points provide an 80% damage reduction. If the total protection enchantment levels on said armor adds up to 10, they would provide 40% damage reduction. This would equate to a total of 88% damage reduction, as damage reduction stacks multiplicatively rather than additively (20% * 60%, rather than 80% + 40%)

Incompatibilities
Protection, Blast Protection, Fire Protection, and Projectile Protection are mutually exclusive. However, if commands are used to have two or more of these enchantments on the same item, the effects stack.
