'''Proc''' is a term that refers a [[skill]], [[item]], or other effect that is activated automatically, usually on some percentage chance. If a [[skill]] An effect in the game has a such as "2% chance of knockback" could be said to happen on have a melee 2% chance of proc'ing. Procs are mostly commonly seen in Diablo III when active or passive skills trigger an effect with every critical hit, then such as the percentage chance is the "proc rate"Wizard's [[Critical Mass]] passive skill.
Procs are widely used in World of Warcraft skills,[http://www.wowwiki.com/Proc] which no doubt influenced the Diablo III developers in their design.
==Procs in Diablo III==
Procs are present The first use of the term in Diablo III came from a tweety by [[@Diablo]] in many game functionsMarch 2011, though they may not be referred when referring to as "procs" by the developers. For instance, functions like function of the [[Barbarian]]'s [[Critical HitRevenge]]skill.[http://twitter.com/Diablo/statuses/48845117712367616] <blue>No it's are procsa skill, it's a proc, which isn't quite the same as they trigger a special effect some set % of the timepassive. </blue>
A major discussion of procs came from [[Wyatt Cheng]] when speaking of the Wizard's [[Energy Twister]]: [[Wicked Wind]] in the v1.0.4 Wizard patch preview developer diary.[http://diablo.incgamers.com/blog/comments/patch-1-0-4-preview-wizard]
The only <blue>Energy Twister is having its proc coefficient reduced from 0.25 to 0.125. For players who may not know what proc coefficients are: they affect how effectively a skill triggers procs (so far) known skill or effects that works as have a proc in Diablo III is the [[Barbarian]]'s [[Revenge]] skill, which was described as small chance to activate). Many skills (like Magic Missile) have a "proc" by [[@Diablo]] in March 2011coefficient of 1. [http://twitterSkills that hit multiple targets or pulse multiple times have lower proc coefficients.com/Diablo/statuses/48845117712367616]
<blue>No it's In the case of Energy Twister, specifically Wicked Wind, the 0.25 proc coefficient causes the skill to generate more procs in a given time period than any other skill. Currently, it's a this is used in combination with Critical Mass to lower the cooldown on skills like Frost Nova and Diamond Skin. By reducing the proccoefficient from 0.25 to 0.125, which isn't the build still works and remains fairly strong, but it won’t be quite the same as a passivegood as it is now. (For those with extremely high Crit rates, you may not even notice much difference, but I wanted to call it out anyway.)</blue>
::“Proc” is almost entirely [[Everquest]] slang... Even in the muds, it wasn’t that widely used because only some codebases used the term. It took EQ publicizing the inherited term to make it common knowledge.
