Block value was number typically appearing on shields that sets the amount of damage absorbed when you block an attack. Some abilities, enchantments, items and spells can contribute bonus block value also. As a stat it appears as "X Block" as the base value on shields, "Increases the block value of your shield by X" as a bonus on shields or a stat on another type of item, and "X additional block value" as an enchant. The block value is increased by one for two points of strength.

Sometimes this number is confused with "block rating", which increases a player's chance to block.

Removal in Cataclysm

World of Warcraft: Cataclysm This section concerns content exclusive to Cataclysm.

Block value was removed as a stat in the World of Warcraft: Cataclysm Cataclysm expansion. Instead, blocks simply mitigate a fixed 30% percent of damage.[1]
