spec (WoW)  

This word is used in several different ways, all related to talent builds.

1. A specific talent build. (My spec is Arms/Fury.)
2. The playstyle associated with favoring one talent tree over another. (A survival spec hunter should focus on items with agility.)
3. Spending Talent points to create your talent build. (I just specced out of shadow for the first time because my guild needs me to heal.)
