Dual Talent Specialization (or dual spec) is a skill players at level 30 can learn in exchange for 10File:Gold.png from their class trainers. Introduced in patch 3.1.0, dual talent specialization is the ability to switch between two talent specs, glyph sets, and action bars on each level 30+ character. Originally 1000File:Gold.png, dual talent specialization has been reduced to a mere 10File:Gold.png most likely to offer players a new experience with their chosen class and/or specific talent selections. It should also be noted that before patch 4.0.3 it was required for players to be level 40 instead of 30, this change was also probably done to offer players more options at a lower level.
