Dodge

Dodge is a form of melee mitigation where the entire melee swing is avoided. Dodge is a passive ability possessed by all players for all classes and races. However this stat is the most important to players fulfilling a tanking role. Only close range melee attacks can be dodged; a ranged attack or a spell cannot be dodged. Players can only dodge attacks if they are facing their opponent, however a mob can dodge attacks that are from behind. Incapacitated targets (stunned for example) cannot dodge.

There are several ways that dodge is modified. You can increase you chance to dodge by increasing your dodge rating which will all increase your effective chance to dodge or dodge percent(%). You can decrease your chance to be dodged with expertise. Expertise is only modified from expertise rating, some talents (such as Combat Expertise), and some passive racial traits for certain melee weapon types. Your chance to dodge a hit as well as have your hits be dodged is affected by the level of your opponent. Different classes and talent specializations will also vary the amount of dodge a player has.

Formulas
The amount of dodge you have is affected by your class, level, talents and dodge rating.

Dodge generally goes into two pools that are added together: undiminished and diminished dodge. Your undiminished dodge includes your class's base dodge, dodge from any talents (such as Anticipation), and the dodge your receive from your base agility.

$$\mbox{Dodge percent} = b + t + A_b + d$$
 * $$b = \mbox{Base dodge}$$
 * $$t = \mbox{dodge from talents}$$
 * $$A_b = \mbox{dodge contributed from base agility}$$
 * $$d = \mbox{diminished dodge}$$}}

During this section, a level 80 protection paladin will be used to demonstrate the formulas. Because the example is a paladin, b has the value of 3.2685, t is 5 from 5/5 Anticipation talents, Ab is 1.7664, and d was 14.3295. These sum to 24.36% which matches the dodge found on the character screen. Additional discussion about dodge from diminishing returns will be explained below.

Dodge from agility
Agility generates chance to dodge (dodge %). For level 80s, you can simply use the Rd value from the table above to find the rate. Note that the base agility (agility from your level and race) plus any agility from talents is undiminished. Agility from your gear and buffs will fall into the pool of diminished dodge. From the game interface, you can easily see what these two numbers are. Mouse over agility in the character window and the white number is your undiminished agility (this will include your talents) and the green number, if there is one, is the additional agility which will contribute dodge with diminishing returns.

$$A_b = D_b / R_d$$

$$A_u = D_g / R_d$$ Following our paladin example again, the paladin has a base agility of 92 and 22 additional agility from the Frosthide Leg Armor leatherworking enchantment. 92 at a rate of 52.083333 for paladins results in 1.7664% dodge from base agility (Ab). The additional 22 agility from gear adds 0.4224% dodge (Au), but will be subject to diminishing returns later on in the calculation.

Dodge rating
$$D_u = \frac{D_r}{R_d}$$ Dodge rating is the final source of dodge chance, and all of this chance goes into the diminishing returns pool (u). It converts at a rate of 45.25 (Rd) for level 80s of all classes.


 * NOTE: The example paladin calculations use the pre-3.2.0 dodge conversion of 39.348, rather than the new 45.25 conversion.

Again following the paladin example, the paladin has a dodge rating of 402. Divided by 39.348 this becomes 10.21% to add to the pool.

Diminishing returns
$$u = A_u + F_u + D_u$$ The final step to solving d from the original equation is diminishing returns. Now we can total the pool that came from two sources of dodge impacted by diminishing returns: agility from gear and dodge rating.

For our example paladin, this is 0.4224 + 5.72 + 10.21 to equal 16.35% of undiminished dodge. Now we apply the diminishing returns formula to calculate d.

$$d = \frac{u \cdot C_d}{u + k \cdot C_d}$$ Cd is the cap for dodge, and k is a constant, and these both vary per class. Using our example paladin, Cd is 88.129021 and k is 0.9560 for paladins. Calculate the equation and the result should is 14.32% of dodge as expected.
