So before and TBC you increase the mana cost of WoTLK Gold the arcane blasts, as well as reducing the casting time of Your Arcane Blast. Now, what does it does is boost the damage of all arcane spells as well in the mana cost of Arcane Blast. This effect is stacked as high as four times, and will last for 6 seconds or until an arcane spell is used.

What this basically means is you're going to stack it up to four times. This at a very general level is means you're gonna stack it up prior to using Arcane Blast and you're gonna use Arcane Missiles to drop this debuff. Then you're going to continue to stack it and I'll obviously cover the specifics of this in the section on rotation.

However, this is a basic arcane change that is pivotal to how the spec works. Now, let's talk about some of the changes to the talent tree. It's not my intention to cover every single talent however I'll attempt to cover the most important ones, the cheap WoTLK Gold ones that should be basic knowledge about. You'll be able to recognize them.
