Block Value: Everything you ever wanted to know

What does Block Value do?

Increases how much damage you absorb with a shield and how much damage you do with Shield Slam.

Do any talents affect Block Value?

Yes. Shield Mastery will increase your Block Value by 30%.

When is Block Value applied?

After Armor and Defensive Stance are taken into account. (this makes it a lot better)

How much does 1 Block Value increase my Shield Slam damage?

1 Block Value = 1 Shield Slam damage.
(note: One-handed Specialization will also affect Shield Slam)

How much does 1 Block Value absorb when I block?

1 damage.

How do I figure out how much Block Value I have?

Manually:
Go up to a mob, apply shield block and let it hit you. The amount of damage absorbed is your Block Value.

Addon:
BlockValueTooltip. Hover over your Block Rating in your character screen and it now shows your Block Value as well

Math:
Block Value + (Strength / 20) - 1

Math with Shield Mastery:
(Block Value * 1.3) + (Strength / 20) - 1

    Do these numbers include using two trinkets and two rings? My math may be wrong, but I don’t think they do.

    You can put 2pc T5 in there too, for an extra 100 block value. Shield block / autoblocker / Shield slam makes for fun crits on low armour mobs. My best is about 2750 in a real world situation. (no enrage / deathwish shield slams on zerk stance naked warriors :P)

    And if you really want to get carried away, there’s a bunch of nice block gear in ZA.

    hey Ven…can you update this list for the ZA stuff? I still look at it super often and it would be awesome to see that stuff side by side with these others. Thanks for all your awesome work!

    Seems there’s a pretty neat undocumented change with 2.4:

    Battleworn Tuskguard - Changed from 40 block rating to 40 defense rating.

    @jjacks: I gotta say I’m floored right now after reading that. It forced me to immediately log on and see and sure enough… it happened. This may very well hit the frontpage of the site tomorrow.

    I’ve been shaking my fist at you for letting me give you that silly hat for days!
    I can’t believe how many of those I’ve had disenchanted.

    I was wondering if you could use itemstats instead of wowhead links. My company blocks wowhead and I cant see item stats by hovering mouse over the item. I can see teh item stats in this topic but not in the 2.4 badge loot pick order

    Nice little guide.
    Theres also a meta gem now that increase blockvalue with 10% i think.

    [Reply]

  14. Okerhs Says:

    There is indeed

    Eternal Earthstorm Diamond

    Eternal Earthstorm Diamond
    +12 Defense Rating & +10% Shield Block Value
    Requires at least 2 Blue gems
    Requires at least 1 Yellow gem
    “Only fits in a meta gem slot.”

    Of course this would mean using a helm that can fit a Meta gem and the Battleworn Tuskguard can’t. Best one is -

    Faceplate of the Impenetrable - 45 Block Value from illidan.

    Question - Does the Meta Gem 10% get accounted for first then the Shield Mastery 30% or taken together as 40%? as this will affect the total value.

    Another option for belt is

    Onslaught Waistguard - 56 Block Value
