Parry

Parry is the name of a passive ability which gives targets of melee attacks a chance to parry each incoming frontal attack. Parried attacks are negated - no damage is dealt. All melee classes except druids have this ability: death knights, monks, paladins, rogues and warriors. Shamans who specialize into enhancement also gain the ability.
==Functionality==
* If a character or mob has a parry chance, it can take effect on every incoming frontal melee attack.
* If applicable, the parry chance is added to the attackers attack table.
* Originally, the only stat which increased the chance to parry was defense (0.04% per point). However, with the addition of death knights, 25% of their strength is added as parry rating (it is important to note that a death knight's high parry rating is one of their mitigation mechanics).
* Similarly items can directly increase the chance to parry.
* Attacks from the rear cannot be parried. Mobs sometimes do so anyway - this can be due to a bug or because they turn very quickly in place.
* When a warrior's special attack is parried, he does not spend all the rage cost associated with that spell (even though the spell fails). Miss, dodge, or block events will consume the full rage cost when the spell fails.

Your chance to parry is based on the formula: % = 5% base chance + contribution from parry rating + contribution from talents + ((Defense skill - attacker's weapon skill) * 0.04)
Your Parry Rating is provided by items that have a Parry Rating bonus.
In combat, you will notice that your Parry percentage match what you see on your tooltips. Miss chance and Critical chance are unmodified by Parry, so you're not "wasting" Parries on misses nor are you able to Parry a Critical. This may seem odd to some folks if they are expecting a "if hit, then check if Parry, then check..." type system. WoW, like many other games, uses a combat results table-based combat scheme (where one roll determines outcome of an attack), so percentages are absolute. Your parsed Parry won't necessarily match your tooltip if you're fighting creatures higher or lower in level to you.
==History==
Prior to the Cataclysm expansion, a redesign of parries was contemplated, where a successful parry would cause the next two melee swings from the attacker to deal only 50% damage. This change was apparently never implemented. Instead, parry was reimplemented to provide the same avoidance as Dodge.
Prior to patch 4.0.1, a parry also reduced the "swing timer" of the defender, effectively giving the defender additional haste. This effect occurred both for characters and mobs, including most bosses. Comments on the mmo-champion forums indicate that the swing timer reset (aka "parry haste") is still be in place for characters. 
Prior to Patch 5.0.4, hunters were the only non-melee class that could parry. Hunters can no longer parry attacks in exchange for the removal of the minimum range for ranged attacks.
==Trivia==
Parry is one of Varian's Basic Abilities in Heroes of the Storm.
