Critical Block

Critical Block is the mastery of protection warriors. It increases the Warrior's chance to critically block an in coming attack.

A 'normal' block reduces incoming damage by 30%. A critical block doubles the damage reduction; a critically blocked attack does 60% less damage, that is, it only hits for 40% of its normal damage.

Critical Block chance is a subset of 'normal' block chance. If a Warrior has 50% block chance and 30% critical block chance it means that 15% of all attacks will be critically blocked and 35% will be 'normally' blocked.
