- Metal is no match for rage. Template:TCG quote
A crushing blow is an attack made by an NPC that is 150% of the Damage caused by a normal successful attack. A Player cannot perform a crushing blow (unless under 
[Mind Control], in which they are treated as mobs).
When the attacking mob has 15 or more points of weapon skill above the player's base defense there is a chance of being struck by a crushing blow. The chance is 2% per point of difference minus 15%. If the rating difference is exactly 15 points, which is common for players being attacked by "boss" mobs (who are always treated as 3 levels higher than their attackers), then the crushing blow chance is 15% (which is 2% * 15 - 15%).
The maximum defense that can be applied by a player against reducing crushing blows versus mobs with higher weapon skill is 5 * the player's level. A level 70 player therefore cannot apply more than 350 points of defense against crushing blows versus level 71 and higher mobs, even if the player's normal defense is higher than 350.
Avoiding Crushing Blows
- Main article: Uncrushability
If your Defense skill is fully trained for your level, neither more Defense, nor Resilience, nor any other kind of bonus can reduce the nominal chance for you to receive a Crushing Blow. The only way to reduce your chance of receiving a Crushing Blow is for your combined chance to be missed, to dodge, to parry, and to block to be so high that the Crushing Blow chance is pushed off the bottom end of your attacker's Attack Table.
102.4% and beyond
Since attacks from a level 73 boss are 0.6% less likely to miss or be dodge, parried, or blocked by a level 70 character, a tank must have a miss/dodge/parry/block rate of 102.4% against a level 73 mob to be immune to crushing blows. This amount of avoidance and mitigation pushes crushing blows (as well as crits and normal hits) off the Attack Table.
Use the following formula to determine your miss/dodge/parry/block rate:
%needed= Base 5% miss + bonus miss from defense + dodge % + parry % + block %
Remember to cast Holy Shield or Shield Block before checking your block chance in game.
Warriors
The warrior ability 
[Shield Block] increases block rate by 75%, removing crushing blows from the miss/dodge/parry/block/crit/crushing-blow table that occurs when an opponent attacks, and making the warrior more or less "immune" to both crushing blows and critical hits in a PvE environment, but only in case that he is immune to crushing blows as shown above. This is because an attack that is blocked (as with a shield) cannot be a crushing blow or a critical hit -- the three are mutually-exclusive attack results. A warrior will take crushing blows if they are hit 3 times in 5 seconds, as the [Shield Block] ability has 2 charges. A mob with an attack speed of 2.0 or faster can therefore crush a warrior if he fails to dodge/parry/miss 3 attacks in a row.
Paladins
[Redoubt] and 
[Holy Shield] together increase the block rate by 60% (30% each). However, Redoubt procs randomly and cannot be relied upon. A tankadin therefore needs to hit 102.4% with only [Holy Shield] running.
This is made much easier with the 
[Libram of Repentance], which increases your block rate by 5.33% while [Holy Shield] is active for a total of 35.33%.
For a paladin with the [Libram of Repentance] to be immune to crushing blows from bosses, the miss/dodge/parry/block rate must be at least 67.07% and [Holy Shield] must be active at all times.
Paladin tanks should also have the [Improved Holy Shield] talent. It provides 4 more [Holy Shield] blocks in that time and increase the amount of damage from each [Holy Shield] proc. The 8 charges of Holy Shield every 10 seconds ensure that almost no boss in the game can expire its charges before its cooldown ends. The charges can still be used up during AOE tanking of trash mobs but they cannot crush anyway, so it is not a big deal.
Druids
Forget it. You will eat crushing blows. This is why bears have their high armor and health. BT/Hyjal druids can push their dodge/miss to 102.4% with trinkets, but this is for a few seconds and has a long cooldown.
Am I uncrushable?
You can use the following macro to determine if you can be crushed. Make sure you use Shield Block or Holy Shield before you press the button.
/script DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 combined avoidance. Currently at:",0.8,0.8,1)
/script DEFAULT_CHAT_FRAME:AddMessage(GetDodgeChance()+GetBlockChance() + GetParryChance() +5+(GetCombatRatingBonus(CR_DEFENSE_SKILL) + 20)*0.04,1,0.5,0)
This macro assumes that you have 20 defense skill from talents. If you have less, you need to edit the following:
(GetCombatRatingBonus(CR_DEFENSE_SKILL) + 20)
to the proper amount of defense via talents.
