The formula for damage reduction by explosions is
(8 × level)%, meaning that for every additional Level another 8% of the damage is absorbed. The highest level (Blast Protection IV) absorbs 32% (
4 x 8%) of the damage inflicted by any explosion. Theoretically at level 13 no damage from explosions is possible (because it should absorb 100%), but the damage reduction is capped at 80%. Blast Protection also reduces explosion knockback by
(15 × level)%.
Protection, Blast Protection, Fire Protection, and Projectile Protection are mutually exclusive. However, if commands or mob drops are used to have something with two or more of these enchantments on the same item, the effects stack.
