Note that there is a difference between "expertise" and "expertise rating". ''Expertise rating'' is typically gained from item bonuses, and for each 7.688690185546875 expertise rating you equip, you gain 1 expertise at level 80.<ref name="EJ-CR80">{{ref web|url=http://elitistjerks.com/f31/t29453-combat_ratings_level_80_a/|title=Combat Ratings at level 80|author=[http://elitistjerks.com/members/1694-whitetooth/ Whitetooth]|publisher=Elitist Jerks|date=2008-07-30|accessdate=2010-03-04}}</ref> ''Expertise'' is typically gained from talents, and for each 1 point of expertise you reduce your chance to be dodged/parried by 0.25%.

==Expertise caps==
  +
For boss-level mobs (which are calculated as your level + 3) the soft cap is 6.5% dodge or 26 (currently at 22 for level 80 content<ref>{{ref web|url=http://elitistjerks.com/f76/t106276-retribution_concordance_4_0_1_a/p9/#post1777185|title=The Retribution Concordance|author=[http://elitistjerks.com/members/267880-jinivus/]|publisher=Elitest Jerks|date=2010-10-18|accessdate=2010-10-26}}</ref>) expertise (200 expertise rating), and the hard cap is 14% parry or 56 expertise (431 expertise rating). Melee DPS classes will usually focus on the soft cap, since bosses cannot Parry when attacked from behind. Some tanks will like to collect a lot of expertise in order to avoid boss parries, which may result in the [[Parry-Hasting]] effect. However, recently the boss [[Parry-Hasting]] effect has been '''disabled on some of the bosses'''.<ref>http://maintankadin.failsafedesign.com/forum/index.php?f=6&t=25841&rb_v=viewtopic&start=15<sup>[broken link]</sup></ref> More information about the bosslist can be found at the references. More information on this effect can be found on the [[Parry]] page.
  +
  +
For level 82 and below (heroic bosses and trash mobs in raids) the dodge and parry caps are the same. You won't need more than about 22 expertise.<ref>{{ref web|url=http://www.tankspot.com/forums/f200/41907-frequently-asked-questions.html|title=Frequently Asked Questions|author=[http://www.tankspot.com/member.php?483-Satrina Satrina]|publisher=TankSpot|date=2008-11-27|accessdate=2010-03-04}}</ref>
  +
  +
===Tanking===
  +
Expertise is of two-fold use to tanks. First, by reducing the target's avoidance, it improves a tank's threat generation (more of his/her attacks will land). More importantly, because mobs may attack more quickly after parrying an attack, expertise reduces the total damage that the tank may receive by reducing the chance that his target parries. The increase in attack speed varies (from 0-40% of the speed of the parried attack),<ref>{{ref web|url=http://elitistjerks.com/f31/t18771-protection_warrior/|title=The Protection Guide|author=[http://elitistjerks.com/members/2828-quigon/ Quigon]|publisher=Elitist Jerks|date=2007-12-03|accessdate=2008-04-08}}</ref> and can stack if multiple attacks are parried in rapid succession, leading to a potential source of massive burst damage. However, this parry-hasting effect from when a boss parries has been disabled from most bosses except the last 3 in 25m TOC.

==Effective Spell Power==
  
−
The effective spell power granted by this item is affected primarily by cast time. This trinket benefits more from shorter cast times.
  
−
The formula for calculating the amount of effective spell power granted by this trinket is:
  
−
E = 590 * 10 / (45 + (t / 0.25))
  
−
Where
  
−
E = effective +spell power
 
−
t = cast time
  
−
The following Java Program can be used to obtain a table of effective +spell power for different cast times.
  
−
public static void main(String[] args)
  
−
{
  
−
float time;
  
−
float effective;
  
−
 
−
for(time = 1; time < 6.5f; time += 0.5f)
  
−
{
  
−
effective = 590 * 10 / (45 + (time / 0.25f));
  
−
System.out.println("<tr><th>" + time + "</th><td align=\"center\">" + effective + "</td></tr>");
  
−
}
  
−
}
  
−

• Note that DPS expertise scores are assuming that the player is attacking the target from behind, and thus only take dodged attacks into account. For targets that can parry attacks (i.e. from with tanks, standing in front of the target), the expertise ratings required to make both parries and dodges impossible would be much higher (see Tanking Expertise Caps, above).
  +
  +
• Also note that the Glyph of Seal of Truth is the only expertise-providing addition listed here that is not a talent or racial bonus. This provides ten expertise points (not rating) to the paladin while active, and requires that the paladin be have Seal of Truth currently cast on themselves.

==Expertise against bosses==
  +
The dodge and parry chances for boss-mobs is currently disputed, but combat parses tend to point at around 6.5% dodge and 14% parry.<ref>http://elitistjerks.com/f31/t37032-faq_working_theories_raiding_level_80_a/</ref> Assuming 6.5% dodge and 14% parry, a player would need 26 expertise (200 expertise rating) to negate a boss's dodge chance, and 56 expertise (431 rating) to prevent parries.
  +
  +
To "cap" expertise against a raid boss, melee DPS need only concern themselves with the boss' dodge chance, provided that they attack from behind. This dictates a goal of 200 expertise rating. Tanks, however, attack from the front, and need to worry about both dodge and parry.
  +
  +
As of 4.0.1a, the expertise cap has been lowered to 23 for current content.<ref>http://forums.worldofwarcraft.com/thread.html?topicId=27397547423&postId=274908951657&sid=1#4</ref> Ignoring racial bonuses, this translates to about 173 for raid bosses.
  +
  +
==Expertise from talents==
  +
Death Knights fain 6 points of expertise from [[Veteran of the Third War]], a talent specialization of the [[Death Knight#talents#Blood|Blood tree]].
  +
  +
Shamans can gain 4/8 points of expertise from [[Unleashed Rage]], in the fifth tier of the [[Shaman talents#Enhancement|Enhancement tree]].
  +
  +
==Patch 4.0.1==
  +
Expertise rating changed from 8.1974973675 to 7.688690185546875 per 1 expertise.
  +
Many talents with expertise were removed from game.
  +
  +
On the character pane, you can also see your percent chance to be dodged or parried by mousing over Expertise in the melee section of the information section.
  +
  +
==Patch 2.3.0==
  +
Expertise was introduced in Patch 2.3.0, replacing effects which increased [[weapon skill]]. With the patch, [[weapon skill]] bonuses for melee weapons were generally replaced with expertise rating bonuses. Talents and [[racial traits]] which increased weapon skill were changed to directly increase expertise (not expertise rating). Items and racials which previously granted ranged weapon skill were changed to grant hit or critical strike rating instead, as expertise has no effect on ranged attacks.

Revision as of 14:49, 20 January 2011

Expertise (also known as Exp and Ept) is an attribute introduced in Patch 2.3.0. One point of expertise decreases the chance that melee attacks made by the player will be dodged or parried by 0.25%. At level 80, every 7.688690185546875 points of expertise rating grant 1 expertise.

Expertise rating

Note that there is a difference between "expertise" and "expertise rating". Expertise rating is typically gained from item bonuses, and for each 7.688690185546875 expertise rating you equip, you gain 1 expertise at level 80.[1] Expertise is typically gained from talents, and for each 1 point of expertise you reduce your chance to be dodged/parried by 0.25%. Thus it takes exactly 30.7547607421875 expertise rating at level 80 to reduce your chance to be dodged/parried by 1%.[1]

Expertise Rating Required Per 1% Dodge/Parry
Level 60 Level 70 Level 80
9.3793201447 14.7904396057 30.7547607422

Racial Bonuses

Certain players get passive expertise bonuses from their passive racial abilities:

  • Humans get +3 expertise with One or Two-Handed Swords and Maces.
  • Orcs get +3 expertise with One and Two-Handed Axes, and Fist Weapons.
  • Dwarves get +3 expertise with One and Two-Handed Maces.
  • Gnomes get +3 expertise with Daggers and One-Handed Swords.

Expertise caps

For boss-level mobs (which are calculated as your level + 3) the soft cap is 6.5% dodge or 26 (currently at 22 for level 80 content[2]) expertise (200 expertise rating), and the hard cap is 14% parry or 56 expertise (431 expertise rating). Melee DPS classes will usually focus on the soft cap, since bosses cannot Parry when attacked from behind. Some tanks will like to collect a lot of expertise in order to avoid boss parries, which may result in the Parry-Hasting effect. However, recently the boss Parry-Hasting effect has been disabled on some of the bosses.[3] More information about the bosslist can be found at the references. More information on this effect can be found on the Parry page.

For level 82 and below (heroic bosses and trash mobs in raids) the dodge and parry caps are the same. You won't need more than about 22 expertise.[4]

Tanking

Expertise is of two-fold use to tanks. First, by reducing the target's avoidance, it improves a tank's threat generation (more of his/her attacks will land). More importantly, because mobs may attack more quickly after parrying an attack, expertise reduces the total damage that the tank may receive by reducing the chance that his target parries. The increase in attack speed varies (from 0-40% of the speed of the parried attack),[5] and can stack if multiple attacks are parried in rapid succession, leading to a potential source of massive burst damage. However, this parry-hasting effect from when a boss parries has been disabled from most bosses except the last 3 in 25m TOC.

• Note that DPS expertise scores are assuming that the player is attacking the target from behind, and thus only take dodged attacks into account. For targets that can parry attacks (i.e. from with tanks, standing in front of the target), the expertise ratings required to make both parries and dodges impossible would be much higher (see Tanking Expertise Caps, above).

• Also note that the Glyph of Seal of Truth is the only expertise-providing addition listed here that is not a talent or racial bonus. This provides ten expertise points (not rating) to the paladin while active, and requires that the paladin be have Seal of Truth currently cast on themselves.

• The expertise rating needed to achieve each expertise number is provided beside each number in parentheses. These numbers are rounded up, and the formula used is 1 expertise = 7.688690185546875 expertise rating.

Expertise against bosses

The dodge and parry chances for boss-mobs is currently disputed, but combat parses tend to point at around 6.5% dodge and 14% parry.[6] Assuming 6.5% dodge and 14% parry, a player would need 26 expertise (200 expertise rating) to negate a boss's dodge chance, and 56 expertise (431 rating) to prevent parries.

To "cap" expertise against a raid boss, melee DPS need only concern themselves with the boss' dodge chance, provided that they attack from behind. This dictates a goal of 200 expertise rating. Tanks, however, attack from the front, and need to worry about both dodge and parry.

As of 4.0.1a, the expertise cap has been lowered to 23 for current content.[7] Ignoring racial bonuses, this translates to about 173 for raid bosses.

Expertise from talents

Death Knights fain 6 points of expertise from Spell misc warsongfocus [Veteran of the Third War], a talent specialization of the Blood tree.

Shamans can gain 4/8 points of expertise from Spell nature unleashedrage [Unleashed Rage], in the fifth tier of the Enhancement tree.

Patch 4.0.1

Expertise rating changed from 8.1974973675 to 7.688690185546875 per 1 expertise. Many talents with expertise were removed from game.

On the character pane, you can also see your percent chance to be dodged or parried by mousing over Expertise in the melee section of the information section.

Patch 2.3.0

Expertise was introduced in Patch 2.3.0, replacing effects which increased weapon skill. With the patch, weapon skill bonuses for melee weapons were generally replaced with expertise rating bonuses. Talents and racial traits which increased weapon skill were changed to directly increase expertise (not expertise rating). Items and racials which previously granted ranged weapon skill were changed to grant hit or critical strike rating instead, as expertise has no effect on ranged attacks.
