Projectile Protection

Projectile Protection is an armor enchantment that reduces damage from projectiles.

Usage
Projectile Protection reduces damage from arrows, thrown tridents, shulker's projectiles or fireball from ghasts and blazes.

The formula for damage reduction by projectiles is, meaning for every additional level another 8% of the damage is absorbed. The highest level (Projectile Protection IV) absorbs 32% of the damage inflicted by any projectiles. Theoretically at level 13 and above no damage by projectiles are possible (because it would transcend 100%), but absorbed damage is capped at 80%, which means that level 10 is the highest that will give any effect.

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

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.
